When it comes to security cameras, there are many mistakes that can compromise the effectiveness of your surveillance system. Don’t make these mistakes when installing your security cameras.
Sounds like common sense, right? Indoor security cameras are tailored to indoor conditions, so using them outside would produce poor quality videos and images. And the same goes for outdoor cameras being used indoors – just don’t do it.
Direct sunlight can damage your camera overtime, decreasing its overall lifespan. In addition, it can wash out images, deeming your footage useless. Consider investing in outdoor housing that can protect your cameras and adjusting the angle of your camera so that the sunlight does not interfere with your images.
You want to be wary of weather conditions when installing outdoor cameras. Be sure to check the IP ratings of the cameras and any additional housing you may invest in. And, if possible, install your outdoor cameras under the eaves for added protection.
That is, unless you have a night vision camera. Cameras without night vision or a comparable feature will not produce any usable images in the dark.
When recording, you must inform others that they are under surveillance. The easiest way is to install a well-designed sign in a high traffic area so that it is seen by everyone. Be sure to check with local laws and ensure you are in compliance with all laws before implementing your surveillance system.
If your mounting equipment is not as sturdy, you decrease performance and safety and leave your equipment vulnerable to tampering or theft. Also, it should go without saying, but please do NOT attach your cameras to the gutter.
Again, this may sound like common sense but it must be said. While it may seem like there are no obstructions when you first install your cameras, sometimes natural elements can change that. For example, on a particularly windy day, a branch from a nearby tree may block your camera’s view. Be sure to consider all potential obstructions before settling on a location.
By doing so, you may invite others to hack, damage, or disable your camera system. In addition, exposed wires can pose a safety hazards for young children and adults.
Again, this makes it easier for intruders to hack, disable, or even steal your cameras. It helps to install your cameras high and out of reach, not only to prevent theft or vandalism, but to also get a better view of the area.
Of course the front door is an important place to monitor, but really, you should be watching all potential points of entry (ex. sliding doors, basement doors, windows).

PTZ security cameras offer Pan, Tilt, and Zoom capabilities for more advanced and comprehensive surveillance. Because of their unique flexibility and broad coverage, PTZ cameras are often chosen to remotely monitor large areas such as parking lots or stadiums. If you are considering installing PTZ surveillance cameras for your property, here are some of the best PTZ camera features and benefits.
Large Field Of View
Depending on where you install your PTZ camera, it could have a 360 degree field of view. In addition, most cameras can be pre-programmed to provide specific viewing angles at pre-determined times. Pan and Tilt can also be pre-programmed. Thanks to this, PTZ cameras can do the job of a multi-camera installation, making them a cost-effective and smart alternative for large area surveillance and protection.
Most PTZ cameras come with built-in tracking which can be set to detect motion and track a person or object, automatically panning, tilting or zooming to follow the person or object as it moves. This feature can prove invaluable should a theft or vandalism occur on your property. When choosing a PTZ camera, full motion tracking capabilities is a must.
This is an important feature in nearly all security cameras, but especially in areas with poor lighting conditions. The modern, more advanced PTZ cameras can capture images in total darkness thanks to LEDs and special IR filters. The small LEDs emit infrared light, which is not visible to the human eye, but with the special IR filter, the camera sees a well lit area.
Remember that a PTZ camera that is rated for a detection range of 600 feet or more will usually be rated for a max range of 400 feet for night vision. Also, it is recommended that you set up your PTZ cameras in the same lighting conditions they will be recording in, whether dark or light.
If you will be installing PTZ cameras outdoors, they must be weatherproof. Most PTZ cameras are designed to withstand harsh elements, but it is wise to double check the specifications to ensure their durability. Weatherproof PTZ cameras can be installed in very remote locations such as rooftops or the sides of tall buildings.
PTZ security cameras have a detection ability that ranges from 150 feet (on the low end) up to 1,000 feet (on the higher end). The ability to zoom in on a person or object ranges from 12X to 36X for higher level PTZ Speed Domes. This makes them ideal for large parking lots or building tops as it allows the camera to be discreetly out of sight while still providing the option to zoom in for a better picture of what is happening.
The best place for a PTZ camera is mounted high above the ground, which enables the best view possible, a wide 360 degree range, and added protection. As mentioned, most PTZ cameras are built tough, with rigid metal housings and high-strength polycarbonate domes that are virtually shatterproof to vandals.
Most PTZ cameras have four alarm inputs, which connect to other important devices (ex. motion detectors, door contacts, glass break sensors). The camera can be programmed so that when activity occurs in a given area, other programmed activity is halted in order to zero in and record what is going on.
The good PTZ cameras will have full range auto focus built in. This ensures clarity no matter where you pan, tilt or zoom. In addition, most have an auto adjust IR LED that quickly focuses the picture when moving the camera in areas of complete darkness. This feature is almost always missing from cheaper cameras.
Because they can cover a wider area, it may be more cost-effective to install a couple PTZ cameras to monitor your property (ex. parking lots, garages) rather than implementing several fixed security cameras. You can save on both the initial cost and installation of your system.
High Definition Options
Higher end PTZ Speed Domes are also available in IP versions, which will deliver resolutions from 720i to 1080P, and with HD-SDI technology, which provides high definition video in full 1080P resolution. The HD-SDI PTZ cameras are easier to install and maintain than IP cameras since they are installed and set up exactly the same way as standard analog cameras.
These types are only recommended when you need the highest resolution images possible. They require 2-4 times as much hard drive space as regular analog security cameras and are rather expensive for large installations.

Surveillance camera systems help to provide home and business owners security, protection, and peace of mind. But did you know you can use your security cameras for additional purposes? Here are some lesser known uses and benefits of security camera systems.
Some cameras come equipped with a time lapse feature which can allow you to create videos to display changes over time. These are great for construction or demolition sites, for capturing weather, nature, or wildlife.
Do you manage a barn, farm, or ranch on your property or remotely? Security cameras can save you time and travel costs by allowing you to check in on your animals remotely. And if you have pregnant livestock, you can keep an eye on the progress and possibly record the birth.
If your family is a fan of pranks, security cameras can come in handy. Features like two-way audio and alarms can startle your unsuspecting guests, and you can capture the reactions as a souvenir.
Did you know security cameras help when checking the forecast? When you see images and footage from remote areas, such as when you are checking a weather application, those are taken from strategically placed security cameras.
Whether it’s your baby’s first steps or first words, you may be able to capture it on video. If you were away when it happened, you can review it later, and you can also share the special moment with other family members and friends.
While the cost of security cameras may discourage homeowners, the benefits of having it should be considered. Aside from peace of mind, insurance agencies often offer a discount as well. And this discount can help to offset the costs of the system.
Nanny cams help to ensure that your babysitter is behaving properly and that your children are safe. On the other hand, nanny cams can also help you keep an eye on your elderly family members and caregivers to make sure your loved ones are not in danger.
Speaking of seniors, especially those who live alone, some home security systems come equipped with emergency pulls or medical alert pendants. When triggered, these instantly dispatch emergency assistance to homes.
Whether it’s the neighborhood kids or unwelcome intruders, your security cameras can help to prevent any trespassing or vandalism.
Have things gone missing or end up in random places in your home? Want to know who finished your leftovers in the refrigerator? You can review your surveillance footage to solve the mystery.
For the gardeners out there, you can set up security cameras with motion detection to monitor your goods. If squirrels, raccoons or the like are ruining your crop, you can set up your motion sensor to sound an alarm to scare off the critters.
Security camera systems enable you to have peace of mind when it comes to latchkey kids. Your system can alert you when someone enters your home, therefore, you will know when your kids get home from school. You may disarm the alarm remotely or have your children do it.
Having a surveillance system already installed in your home can increase the resale value of your home. It can also keep your home protected during the selling process as you can keep an eye on the strangers that come and go during open houses and inspections.

When it comes to securing your property, CCTV cameras can be very effective. However, because there are a wide variety of CCTV cameras suited for different applications, if they are not properly implemented, their effectiveness may be compromised.
Before choosing your surveillance system, review the different types of CCTV cameras and the application for which they are best suited.
Different Types Of CCTV
PTZ (Pan/Tilt/Zoom) Camera
What To Consider
Choosing the right CCTV camera for your property is important. You want to evaluate your needs to determine where you will place these cameras as well as their primary use in that location. Some factors to consider when choosing include the lens, sensor, and output resolution.
The lens will dictate the quality of the image. The appropriate lens will allow your camera to focus and bring in enough light to the sensor, providing clarity and the ability to better identify things such as faces and license plates. A zoom lens will allow for further detail since it can adjust the light as it reaches to sensor for enhanced pictures and flexibility.
There are two types of sensors:
CCD are more expensive than CMOS and produce clearer images (ideal for identifying faces and license plates).
Generally speaking, the more pixels, the better the picture. The highest resolution you can get is 700TL, but most cameras range between 300-550TVL. Be sure to match a resolution that your camera can produce because anything more is unnecessary.
Other Things To Consider:
Box cameras are easier to be seen and clearly tell passersby that they are being recorded, which acts as a great deterrent. Dome cameras, on the other hand, are smaller and more discreet, making them ideal for monitoring larger areas such as front or backyards.
Consider where you will place your cameras both indoors and outdoors. If you plan on placing them outdoors, you want to ensure they are in the best location and well protected (weatherproof and vandal proof housing). For indoor cameras, you want to make sure it will not be affected by things like grease or steam from the kitchen.
Whether indoors or outdoors, lighting will always change so it is advised that you test different camera models to see what works best with your lighting conditions. You also want to check for any reflections or backlighting during day or night.
This will depend on the size of the area you want to monitor. Thus, a camera situated in a small room need not be of high resolution. The resolution of your CCTV camera should reflect the landscape in order to provide effective images.
This depends on your personal preference (you should also look into the laws regarding audio recording if applicable). Some CCTV systems allow you to speak to the intruders, or you can have audio or alarms sound automatically when they reach a certain point. These tactics are meant to scare the intruders away before they can cause damage.

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:
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.
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.
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.
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.
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.
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.

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.
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 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.
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.
