Wired Security Cameras Vs. Wireless Security Cameras
Security cameras offer great benefits for various settings. From protecting your business or property to keeping an eye on nursing homes or daycare centers, surveillance camera systems can be incredibly helpful.
The extensive surveillance market is like a double-edged sword. While there is likely a security solution for nearly every need, sorting through the options to find the best security solution for you can be seemingly endless. However, with the proper approach and assistance, you can find a suitable surveillance system in a timely manner.
When shopping for security camera systems, it is best to evaluate your needs and research which solutions may better suit you. For example, choosing between wired or wireless security cameras can be determined by weighing their advantages and disadvantages, while understanding how these can play into your specific requirements.
To help you choose which is better for you, here are some basic pros and cons of both wired and wireless security cameras.
Wired Security Cameras
Pros
- Video is transmitted straight to your recorder with no interference from other wireless devices.
- A wide variety of camera styles are available.
- Wired cameras make it impossible for the signal to be jammed.
- IP-based wired cameras can provide video resolutions at High Definition and beyond, transmitting large amounts of data over CAT5 cabling.
Cons

Security Cameras: Types, Housing & Features
Shopping for security camera systems may seem like a one-size-fits-all deal, but, unfortunately, it is not. Because there are a plethora of security camera types and surveillance features to be considered, it will take some time to decide. Evaluate your security needs, do some research and weigh your options. To make it easier, we will break down the different types, housing, and common features of security cameras.
Types
The following are the advantages and disadvantages of common security camera types.
- Fixed – As the name suggests, fixed cameras are positioned to capture an image and are always pointing in the intended direction. Because these do no move, they are more reliable than PTZ cameras and can be optimized with different housing and features.
- PTZ Cameras– PTZ stands for Pan, Tilt, and Zoom, thus, these cameras can be remotely positioned (thanks to specially designed motors and gears). These cameras may be set to automatically patrol an area, but they seem to be most effective when manually controlled.
For zoom capabilities, 32X is fairly common, although some higher end cameras may have a greater zoom range. While a greater zoom range is helpful when covering a large area, it is not always necessary.
However, there are some downfalls. Because PTZ cameras can adjust its viewing range, there are chances that they may miss something. Also, zoom decreases the size of the area being covered, and the camera can only be facing one direction at a time.
- 360-Degree Cameras – Also known as virtual PTZ, the 360-degree camera utilizes several high resolution fixed cameras in a single housing (usually dome). The images are then stitched together and can be zoomed in on after recording (zoom capabilities depend on the cameras being used). Because this type of camera can face in all directions, it can be an effective forensic tool.
Unfortunately, these cameras are often oversold as a universal solution, despite the fact that very few rooms allow for an unobstructed view in all directions. In applications where this camera is necessary, it often does wonderfully. However, a standard fixed camera can be paired with a lens to give it a 120-degree to 140-degree view. Also, many rooms are better monitored with cameras in corners (which only require a 90-degree field of view).
Housing
Once you have chosen the camera type, housing will come into play.
- Outdoor – Because of changing environmental elements, outdoor camera housing will be more weather resistant and include heaters and blowers.
- Dome – These are designed to obscure the direction of the camera to outsiders. This is often the best deterrent, making it a high priority and often a default selection. Most people assume dome cameras cover the entire area, making a fixed dome camera covering a door entrance more effective.
- Bullet – These are named for their sleek, cylindrical shape, often times resembling a bullet. This housing clearly shows the direction of the lens and generally provides a better picture. The front of the housing is close to the camera lens, decreasing reflections and making it easier to maintain. These act as deterrents as well, but are not as effective as ambiguous housing.
- Discreet – These completely disguise the camera as something else, such as a smoke detector or motion sensor, or as nothing at all, with pinhole or flush mount lenses installed in a wall or ceiling. Because they are hidden, they are not designed to be deterrents. These are often favored by architects looking to achieve a certain aesthetic.
All types of housing can be made to be vandal resistant, which is a step up from weather resistant. These types of housings are most commonly dome shaped and are designed to withstand unfriendly environments while still providing a usable image.
Features
The selection of features for your security cameras will depend on the application and your individual needs.
- Resolution – Resolution is measured in megapixels (millions of pixels) and is a major factor in picture and video quality. The higher the resolution, the more space required to store the images and processing power to manipulate it.
To demonstrate the differences in resolution, an old analog camera is about ¼ megapixel, an HDTV screen is just over 2 megapixels, and the highest resolution projected image in movie theaters (4K) is 8.8 megapixels.
While higher resolution cameras may be appealing, these do not respond as well as lower resolution cameras in low light situations. Thus, it is possible to buy more resolution than you need, unnecessarily increasing storage costs while decreasing performance.
- Low Light – Cameras with day/night capabilities are able to automatically adjust modes in various lighting situations. With advanced technologies, these cameras are able to produce usable images in near total darkness.
There are also cameras with infrared illuminators, which provide their own light source to obtain better images in low light settings. As mentioned, in order to improve low light performance, you will need to sacrifice some resolution.
- Lens Features – Varifocal lenses allow the installer to manually adjust the image magnification when installing the camera. However, many fixed cameras now come with remote zoom and focus (allowing the user to adjust the camera without physically going to the camera site), as well as auto-focus.
- Advanced Options – Other options to consider include wireless signal transition, ultra-high resolution, thermal imaging, explosion proof housings and more.
No matter what the application, there’s likely a perfect security solution thanks to the comprehensive options available. And while the selection process may seem overwhelming, we are here to help.

Transitioning From Analog Security Cameras To IP Surveillance
Upgrading your analog security cameras to IP security cameras has plenty of benefits, including improved image quality and advanced features. Most IP surveillance systems can make use of existing network infrastructure that is in good condition, decreasing costs for installation. Whether you are looking to upgrade because your analog system is reaching end-of-life for support or because your needs have changed, an IP surveillance system is a smart decision.
Now, the actual task of transitioning from analog to IP security cameras should not be taken lightly. You want to be sure that you take all things into consideration to ensure that you choose the right IP video surveillance system and that it performs sufficiently. Here are a few aspects you should not overlook:
Goals & Challenges
If you are looking to achieve ROI, you must fully understand how your IP security system will be used. Operational goals and potential challenges should be determined beforehand. Think about what types of cameras and how much resolution you need, as well as how long the footage needs to be stored and which areas need coverage. Proper planning is crucial to the success of your security system.
Budgets
No one wants to pay an arm and a leg for a mediocre surveillance system. If done correctly, you don’t need to. By defining a security budget, you can find the right cameras and video management software (VMS) to fulfill your needs and achieve your goals.
Time
As much as a quick transition sounds ideal, it is not always feasible. Understand that a proper transition will take some time, and it may be in your best interest to plan a phased migration. This will help to accommodate budget availability and operational disruptions. Prioritize which area needs immediate attention and begin there.
Storage
Going from analog to IP improves video quality, but also requires more storage. Advanced VMS can help to effectively optimize your network resources and bandwidth consumption, thus decreasing networking and storage costs over time.
Staffing
A new IP video system may need additional staffing, so you should think about this and how you will train the new and existing staff. This will impact both overall costs and ROI of your system, and may affect cameras and software selection. For example, casinos require live monitoring around the clock while parking lot surveillance may use video analytics to alert security personnel of incidents or events that need attention.
Integration
Numerous third-party integrations can help to increase the efficiency of your system as well as manage costs. While most current systems have an IP-based interface for integration, leading suppliers also have a wide range of integrations which are tested and ready to apply. These can offer functionality, automation, and other enhancements to solve project needs.
Cybersecurity
Cybersecurity is of utmost importance, especially these days. If not addressed properly, going from analog to IP opens up your system, and any indirectly connected networks, to endless vulnerabilities. Be sure to discuss your specific network safeguards, policies, and strategies with your installer. Also, enlist a new IP security system that provides the appropriate cybersecurity architecture, software, devices, and policies.
Licensing
Pay attention to licensing requirements and Software Upgrade Plans (SUPs) or Service Level Agreements (SLAs) that come with most VMS systems. These cover everything from higher tiers of support to future upgrades. For example, third-party cameras may require a license for each IP address, and these licensing requirements can add additional costs.
Environmental Conditions
These include extreme heat or cold, humidity, corrosion, and high dust levels, along with ambient light levels, existing power sources, and network infrastructure. All of these can impact which security cameras and VMS equipment are necessary for you.
Redundancy
Because your security system should be operational and accessible at all times, it is important plan provisions for redundancy and back up for primary resources in case they fail. For most systems, simple RAID-5 or -6 redundancy in storage is sufficient. However, you should also consider budgeting for “failover” recorders and other server hardware, and have spare cameras on hand in case of failure.
It is only a matter of time until IP surveillance is the norm and analog security cameras are a thing of the past. But when the day comes, it is ever important to understand your security needs and what you expect from your IP surveillance system. Even a small mistake or misstep along the way can compromise your system.

Home Security Mistakes & Tips
Making mistakes when it comes to your home security can compromise your safety, leaving you vulnerable to burglary and theft. When choosing the best home security system for you, avoid making these common security mistakes and ensure that you properly safeguard your home and loved ones.
Mistake: Buying The Wrong Home Security Systems.
There is no “wrong” home security system, however, what works for one person may not work for you. This is precisely why there are various types of security systems on the market.
In order to choose the best system for you, do your research. You want to look at different reviews from reputable sources. Search the security system you are eyeing, or the type of system you’re looking for. In addition to reviews, pay attention to any complaints from real buyers that you may come across. There may be legitimate issues that you should know about before making a purchase.
Also, these are some important features you should consider when shopping for a security system:
- Remote monitoring
- Real-time notifications
- 911 & emergency services
- Input capacity
- Ease of installation
Lastly, to help you make the right decision, and possibly save you time, you should speak with a security professional. With expert knowledge and experience under their belt, a security professional will have a better idea of which type of security will best suit your needs.
Mistake: Not Testing Your Configurations.
It is rare that one home security system is enough for all your home security needs. For added protection, some components to consider may include:
- Indoor and outdoor cameras
- Motion sensors
- Smoke detectors
- Carbon monoxide detectors
- Glass break detectors
- Door and window sensors
- Freeze sensors
- Water sensors
- Driveway sensors
Of course, these are just some of the many components you may or may not want to add to your system. Whether you have one security camera or 20 different cameras and sensors, you should test all of them to ensure proper configuration and performance. For example, you may not know that your camera is poorly positioned or that your alarm system was not properly activated.
Try simulating a break-in with a friend, family member, or your pet to determine the capabilities of your home security system. Most criminals are seasoned vets so they probably know how to bypass one of more components of your system, thus having more aspects can help to ensure they are stopped.
Mistake: Lack Of/Poor Maintenance Of Home Security System.
Your security system should be maintained on a regular basis, whether it’s weekly, monthly, semi-annually or annually – do what’s best for what you need. Maintenance can involve various things such as updating software, changing batteries, changing faulty or defective parts, and more.
Professional Maintenance
Professional maintenance can be done annually or semi-annually. You may want to check if your vendor offers any maintenance packages in the service contract. If they don’t, you can enlist the services from a home security inspection company.
The services typically consist of the following:
- Repair or replace broken parts of your home security system
- Test the control panel and all other components of your home security system
- Check that signals are sent to and received by the monitoring center
Professional maintenance ensures that there’s no guesswork in handling, fixing or replacing faulty components of your system.
DIY Maintenance
Your DIY checklist should include:
- Check/change exterior lighting to ensure clearer pictures or videos for your surveillance cameras
- Simulate intrusion to check if motion sensors will detect it or trigger the right alarm
- Test your control panel if it has a test model but if your system includes remote monitoring (which it should), inform the monitoring team to avoid starting a false alarm
- The National Fire Alarm Code requires annual inspection of residential household fire systems, but you can press the test button of your smoke detector to see if it’s functioning properly from time to time
Keep these tips in mind in order to avoid these critical mistakes when shopping for a home security system.

Low-Light Security Cameras
There’s something to be said about low-light security cameras. Because lighting conditions in different environments are not always ideal for surveillance, low-light security cameras enable us to capture respectable footage in these situations. And with new technology, the quality of low-light camera images has vastly improved.
But before you invest in low-light security cameras for your home or business, here are some important facts and tips to know to make the most of your security systems.
Here’s some important information in order to make the most of your security systems.
First and foremost, you should know the related terms you may come across:
- Low-Light
- Day/Night
- Starlight
- SenseUp
- Night Vision
- Light Finder
- Light Toucher
- Dark Finder
- Light Catcher
- Thermal Imaging
All of these terms refer to the same classification of surveillance cameras. And while some of these terms are trademarked by manufacturers, the most commonly used terms for these cameras are “low-light” and “day/night.”
How It Works
Despite the sometimes confusing terminology, the basic components remain the same for all low-light cameras: a lens and sensor and some level of image processing. And to be clear, low-light cameras are different than thermal cameras (which track heat rather than motion or images) or cameras with IR illuminators.
A majority of low-light cameras use an IR cut filter, which is a mechanical filter that sits between the lens and the sensor (CMOS chip). The name is derived from its ability to “cut out” or filter out IR illumination during the day to improve color quality. At night, as available light diminishes, it slides out of the way to allow more light to get the sensor, thus improving low-light video quality. In order to help the video quality, it is also captured in black and white. In most cameras the filter is mechanically driven by an algorithm, however, some cameras allow manual control.
Optics
Because nearly all the cameras contain IR cut filters, it comes down to the lens and the processing to set these items apart from one another. The lens transmits light to the sensor and then the data on the sensor is processed by a processor. The variance among cameras is often in the optics. You want to be sure that both the lens and the sensor are of great quality, otherwise the potential for stellar images will be wasted.
Processing
Aside from the optics, processing is an important factor in determining the best low-light camera for you. Most manufacturers employ the same OEM processor yet make their own adjustments to them. The ability to control the tuning of an image is crucial as the tuning of an image during daylight will likely not hold up at night or in complete darkness.
Pay close attention to image toning, noise suppression, and the ability to maintain color and contrast in low light as these often differentiate one camera from another.
Lux
Typical IR cameras will capture images between 1 lux and 0.1 lux, however, the latest technologies can allow .01 lux to 0.00001 lux. This means that what would have been a completely black image a few years ago now looks like a near-daytime picture thanks to new low- and ultralow-light sensors.
While this achievement is impressive, in reality, there will rarely be any situations where there is complete darkness. Some ambient light will likely be present, whether it is from street lamps, the moon, or even the stars.
Spec Sheets Vs. Live Demo
As discussed, the impressive low-light sensitivity and lux will likely be included in the spec sheets, along with other important features. However, these spec sheets often represent technical specifications as opposed to actual performance.
Instead of simply relying on spec sheets, try to find a manufacturer or company that will provide you with a live demo and comparisons. This will give you a better idea of the low-light camera’s performance and whether or not it lives up to your requirements. In addition, third party reviews can give you more insight as well.
Resolution
Just because a camera boasts a high megapixel count does not necessarily mean it will produce a better low-light image. With higher resolution and higher megapixels, each pixel becomes a smaller percentage of that sensor. For example, image the sensor has a fixed size, yet the resolution is doubled. The pixels are smaller, thus, the sensor for each pixel is also smaller, increasing the amount of sensitivity needed to maintain the same level of quality.
Lens Speed
The speed of the lens is important and investing in a fast lens and better optics is crucial. The lens determines what information reaches the sensor, and, because of this, you get what you pay for when it comes to lenses and optics.
Positioning & Distance
Proper positioning of your security cameras is critical. Focus on what you want to capture and the level of detail you need when choosing the location of your cameras.
Position surveillance cameras so that the common range of motion is moving across the field of view rather than having common movement coming toward the camera. Also, avoid bright light pointing directly at the lens – this can cause flare or “fog” on the image.
Consider the field of view in terms of distance. The level of detail from the camera is highly dictated by how close the camera is and how much it’s zoomed in.
And when it comes to distance, you want the right combination of lens and camera that factors in the distance from the area you are trying to monitor. If you need to detect motion from long distances, your best bet would be to switch to thermal cameras. Activity will be detected, however, it will be harder to determine whether it is a person or an animal.

Home Security Camera Placement Tips
When it comes to security camera systems, you can invest in the best, most advanced equipment, but choosing poor locations for your security cameras can render your system ineffective.
In order to choose the best placement for your surveillance cameras, you should consider the layout of your property and which areas need monitoring. Most home or business owners target high traffic areas and entryways.
Here are more helpful tips for installing your security cameras.
- The most commonly targeted entryways are the front door, back door, and first-floor windows, so be sure these are under video surveillance.
- In addition, a security camera at the front door can act as a digital peephole since you can access your live feed to see who’s at the door. You can place it above the door or window frame facing downward so that it covers the area a few feet in front of the opening. Or you can place it inside your home on the window sill overlooking the front yard.
- The type of camera will also help determine where it should be placed. Surveillance cameras with a focus range of around 45 to 75 degrees should be aimed at specific areas (ex. doorway, garage). Wide angle cameras should be placed where they can view 75 to 180 degrees without any obstructions. For security cameras that can rotate, be sure to check with the manufacturer for information on how much unobstructed viewing area is necessary.
- For surveillance cameras being installed outdoors, be sure they are waterproof, vandal proof, and have night vision capabilities in order to record overnight. Motion detection lights around the perimeter of your home can also help capture quality recordings as well as deter burglars from approaching.
- In addition, when placing security cameras outdoors, you want them to be visible yet out of reach. By installing them at least 9 feet above the ground, you decrease the likelihood of tampering, vandalism, or theft of your cameras.

CCTV Home Security Camera Systems
For the best home or business security, it’s important to choose the right CCTV security cameras. With the wide selection of security cameras to choose from, the task can seem daunting. To help ease some of the stress, here are a few things you should focus on when shopping for the perfect CCTV security system.
- Cheap ≠ Cost-Effective
You always want to invest in good quality, but sometimes the ideal option falls a little bit out of your price range. That doesn’t mean you should just go the cheap route as this can end up costing you more in the long run. Remember, more often than not, you get what you pay for. Look for reputable security companies that offer a range of options from solid brand names (ex. Hikvision, Dahua, Axis) and pay attention to warranty offerings (reputable brands usually offer up to 3 years).
- What Do You Need To Record?
Consider what you need to record in order to narrow down which specific camera functions you require. From fixed position to a range of angles, and up to 360-degree range, there’s a security camera for that. Also consider the location of your camera and the environment as there are a variety of cameras that can accommodate as well.
- Lenses Explained
Don’t understand the lens size of wide angle degree for CCTV cameras? We’ve got you covered. The rule of thumb is that for each millimeter of lens size that is how far away in meters the camera will be able to view its subject (focal length). The degree of the wide angle lens will determine the field of vision and shorten the focal length as the angle gets wider.
For example, let’s say you have a camera with 60-degree wide angle, 4mm lens. This camera will be able to effectively identify a human target at up to 4 meters, but will not have enough range to view a neighbor’s property to the left or right.
- Storage & Data
When it comes to storage and data, it will depend on the security camera and how long you will need to store your footage. IP cameras can connect to your network and enable real-time notifications as well as send data to your provider’s control center.
HD security cameras require better bandwidth and internet connection and may consume lots of data when accessed via mobile devices. They also require higher levels of storage to maintain their high resolution and quality.
- Analog Vs. HD Vs. IP?
The quality of images you need from your security cameras will often determine the type you choose. Analog cameras offer low-resolution images, and thus, decreased storage demands. HD cameras can record higher resolution images and are suitable for identifying numbers and characters. They also retain quality when digitally zoomed in. While basic analog cameras may be more affordable, if you’re looking for higher quality footage, you may want to opt for high definition or IP cameras instead.
- Positioning
If you have the best security cameras in poor locations and positions, what good are they really? Think about your property overall and begin by covering the perimeter. By securing the perimeter, you can get an early warning of any suspicious activity, allowing you to act accordingly and in a timely fashion. Also, having your security cameras in plain view but out of reach can be an effective deterrent.
- Lighting Situations
Typically, CCTV surveillance cameras can record color during the day and revert to black and white recording at night. You can supplement your day and night cameras with motion sensor lights, which will allow for sufficient lighting for better images when motion is detected. Low light cameras are another option and may not need supplemental lighting.
- Consider All Costs
When shopping for a CCTV system, you are not just buying cameras. Keep in mind the cost of other necessary items such as recorders, cables, connectors, an uninterrupted power supply, as well as the cost of labor, installation, and possible service provider fees.
- Advice From Security Professionals
Seeking advice from a security professional will give you better insight as they can assess your property and provide the best solutions to suit your needs. Here at SecurityCamExpert, we can provide site surveys and free quotes, along with quality equipment and professional installation. Feel free to contact us 888-203-6294.

Hidden Spy Cameras
Before, spy cameras, like the ones seen in the movies, were merely pipe dreams. The ones that were available never really lived up to the expectation. Fortunately, technology improved over time and hidden cameras became more accessible to everyone.
Thanks to the Internet of Things, Wi-Fi enabled hidden cameras and DVRs are affordable and being used more frequently. You can use these wireless hidden cameras to keep an eye on your children, watch your home while you’re on vacation, or even monitor your business remotely. Hidden spy cameras can be monitored via an app or specialized software that you may access from your smartphone or tablet.
By employing wireless hidden cameras, you can discreetly keep an eye on things. Also, they are less susceptible to tampering as they cannot be easily detected. While visible CCTV surveillance cameras are meant to deter people from wrongdoings, hidden cameras are intended to catch people in the act.
Most hidden cameras are wireless to remain inconspicuous, however, not all are truly wireless. Some are battery powered, while others may need to be prudently plugged in or attached to the electrical system in some way.
What usually confuses people when they see the term “wireless” is that it more commonly refers to the Wi-Fi connection, meaning you don’t have to connect it to any sort of landline or Ethernet cable. Most of these cameras come with their own software and must be configured to your network. IT may sound complicated, but it is no more difficult than connecting any other device to the Internet. However, some spy cameras require that users have an adequate working knowledge of IoT technology to operate them.
Before installing a hidden camera, be sure to review the laws regarding hidden cameras, surveillance, and recording.

Night Vision Cameras Vs. Thermal Cameras: Which Is Better For You?
When it comes to securing the perimeter of your home or business, you want a surveillance system that can perform in various conditions. For 24-hour monitoring, night vision cameras have been the popular solution. However, the emergence of thermal cameras has provided a more advanced solution. Learn more about the different types of night vision cameras and how thermal cameras differ from them.
Low-Light Cameras
These are also known as day and night cameras and electronically and automatically adjust lighting capture settings based on the time of day to produce optimal video images. During the day, IR cut filters are used to “cut out” IR illumination, allowing for color images. At night, the filter is removed entirely to allow the maximum amount of visible and IR light to reach the sensor and produce a monochrome image. The downside to these cameras is that they are completely dependent on lighting conditions. That is, too much light or no light at all will result in unusable images. Thus, the amount of visible light available drastically affects the image.
IR Cameras
IR cameras have a lens that is surrounded by LEDs which emit a beam of near-infrared energy to bounce off objects in its field of view. The image sensor is then able to create a picture; however, distance plays a crucial role in performance. Because the reflected IR light can only reach so far, these cameras are often limited to short-range applications.
Night Vision Cameras
Night vision goggles (NVG) and cameras capture visible light photons. As the photons penetrate a photocathode tube (which acts as an image intensifier), they are converted to amplified electrons that pass through a phosphorous screen and converts them back to visible light to create a picture (often in a greenish hue). Because these devices need just the right amount of visible light to function, they are virtually useless when there is ample light outside (ex. twilight) or in conditions where light is blocked (ex. smoke) or no light is available.
Thermal Cameras
Rather than performing based on light availability, these cameras produce video surveillance images based on the measurement of the electromagnetic heat radiation emitted by all objects and individuals. Their performance is unaffected by bright lights, complete darkness, foliage, and light fog. No matter how small, differences in heat are picked up and produce images with high contrast, which are essential to the success of video analytics and intrusion detection. These cameras may be better suited for properties which require strict perimeter security (ex. oil and gas industries, data centers, mines, power stations), and are often combined with other layers of protection (ex. fence sensors, microwaves, PTZ cameras).
Thermal cameras also boast long-range detection capabilities, thus, reducing the number of cameras needed. They can also be a good substitute for fences where fence installation is not possible. For example, ports and oil refineries have acres of water and land to secure and monitor. Thermal imaging and video analytics can create “virtual fence” and can be a more feasible and affordable solution than installing a physical barrier.

Why You Need IP Security Cameras
Security camera systems have made great advances over the years. From traditional analog CCTV technology to IP networking, security camera quality and features have improved to provide better monitoring and security. Some of these enhanced benefits include higher resolutions resulting in clearer images, fewer cameras covering larger areas, and thus, a lower total cost of ownership. Many businesses and homeowners are opting to trade up to network IP security cameras, network video recorders (NVRs) and cloud-based storage for more convenient and affordable security.
Network IP Cameras & Assisted Living Communities
Aside from protecting homes and company headquarters, assisted living communities can also reap the benefits of installing network IP security cameras.
In the way that security cameras deter burglars from targeting your property, in assisted living facilities, the aim is to deter abuse and neglect. By strategically placing these cameras in and around the facility, family members can put their worries at ease by reviewing stored footage to ensure that no mistreatment is taking place and that the staff is providing the proper care. For facility managers, video surveillance footage can provide evidence should an employee or resident be charged with abusive behavior.
Network IP cameras can also help the staff keep a closer eye on residents or patients. For those residents at risk for falls, staff can potentially prevent falls and injuries, or respond faster to those incidents. Medical equipment such as oxygen tubes may get dislodged, and staff can get to the rooms faster to fix the problems. In the case of memory units, the entrances and exits can be closely monitored to prevent residents from wandering outside of supervised areas, and can help protect the facility from possible intruders.
These security cameras can also prevent employee theft. Although we would rather think that this is uncommon, it is not unheard of for residents to report their belongings stolen. Whether these claims are accurate or not, cameras provide evidence to prove what really happened. Also, facilities often find that supplies may go missing. To counter these losses, IP cameras can document the incident or prevent it from occurring in the first place.
Of course, opponents of these security measures stand firm in their belief that it makes it more difficult to recruit staff and that employees will have trouble making sound decisions for fear of families challenging their actions. The problem with this stance is that numerous other careers and industries are under constant surveillance with little to no issues arising. Proponents of employee surveillance believe these measures will help workers to make better decisions and avoid any questionable situations.
Why Should You Upgrade To IP Security Cameras?
As stated, upgrading to IP security cameras comes with a myriad of enhanced benefits. Aside from the obvious video quality improvement, IP cameras are able to utilize your existing CAT5 or CAT6 Ethernet cabling, saving time and money on installation. The intelligent video features include facial recognition, motion detection, audio detection and people-counting, to name a few. Also, because they are connected to the Internet, owners are able to remotely view live video, search archived footage, and receive alerts via any PC, tablet, or smart phone.
Choosing the Right IP Security Camera
Because the various IP camera choices on the market, it can be a bit overwhelming. Here are some important features you should know about before choosing the best IP cameras for your needs.
- Camera Types
There are three design options for IP cameras: bullet, dome and PTZ (Pan, Tilt, Zoom). As inferred by their name, bullet cameras resemble a bullet shaped and best suited for directional monitoring. They typically do not possess the capability to zoom in or move. Dome cameras are shaped like domes and ambiguously monitor areas, aiding in its role of deterring misconduct. “Speed domes” spin quickly to capture a broader range of images. Lastly, PTZ cameras are ideal for covering large areas. These cameras can move and capture different angles, thus, delivering the work of several fixed-point cameras in one single device. PTZ surveillance cameras may also be preprogrammed to scan an area or may be controlled remotely.
- Resolution
IP camera resolution is the amount of visual data that can be captured and is measured in megapixels. It is often provided in horizontal and vertical pixel dimensions (ex. A camera that has 1280 x 1024 resolution is 1.3MP because 1280 x 1024 = 1,310,720 or 1.3MP). A higher resolution means the camera can capture more data, resulting in improved video clarity.
- Power over Ethernet (PoE)
This allows you to transmit power over the data cable, which can run up to 100 feet. This will save you money and decrease installation limitations. In addition, the PoE standard 802.3af supports higher power ratings needed for motorized cameras (ex. PTZ).
- Wide Dynamic Range
If you are monitoring an area that has challenging lighting conditions, you will want a camera that has good wide dynamic range (WDR). This will control the backlight and remove shadows to produce adequate footage in difficult environments.
- IR LED
Infrared (IR) LED lighting is like night vision, allowing cameras to capture clear footage in low to no light conditions. IP cameras can see infrared light and when wavelengths reflect back, it is as if the room is illuminated and the camera can record video. Night vision capabilities improve with more IRLEDs and longer ranges.
- Weather/Vandal Resistance
If you are using your surveillance cameras outdoors, be sure to choose weatherproof and “vandal resistant” cameras, which will often be IP66 rated and IK10 rated respectively. This will safeguard against water or dirt, which can interfere with your recordings or damage your equipment. Some cameras even offer thermostatic controls, which will help to prevent condensation forming over the lens.
