4K video is the latest in surveillance technology, delivering exceptional image quality and resolution. With four times the resolution as 1080p HD, 4K video blows high-definition video and older standard video formats out of the water. But, without careful planning, its effectiveness can go down the drain.
Switching to 4K video, or even HD cameras, is not as easy as simply buying the new cameras. While HD cameras require four times the storage and bandwidth as a legacy 480TVL camera, 4K cameras require four times the storage and bandwidth as an HD camera. Without the proper equipment to support such requirements, your new 4K system may not live up to your expectations.
Here are a few things to consider when you decide to adopt the new 4K technology.
Data Switches
Simply adding 4K cameras to your current system can quickly overwhelm it. On a normal data network, legacy 100Mbps is standard and is designed for computing data, not video streaming. Normal user data is considered “bursty” because user data is sent in bursts and remains low until the next burst. Memory buffers are built in so that if more data is received than can be processed, the data is stored until it can catch up.
Unfortunately, video streaming does not work like that. Video is sent in a steady stream, and if more data comes in than can be handled, the switch does not have a chance to catch up. This overload of data can result in dropped videos, or the switch may even lock up until it is rebooted.
Imagine a system that has 10 20-megapixel cameras sending at 3.5 fps, and requiring about 112Mbps of bandwidth. Hooking these cameras up to a 110Mbps switch will overload it, causing the system to malfunction. In the same vein, if you have two 110Mbps switches that have five 20-megapixel cameras each, they require about 56Mbps each and should work accordingly. However, if these switches connect back to a main switch that cannot handle the workload, you end up with the same problem as the first scenario.
When choosing a switch for your system, there are many things to consider aside from the port speed. Location is important, whether it be a core switch or a field switch. Also, you will want to pay attention to its switching capacity and buffer size, along with different features and support.
Server/NVR
When it comes to server-based NVRs, again, if it is not designed to support and record at levels up to par with 4K or even HD cameras, you will come across performance issues. Things like bus speed and read-write speed on hard drives will affect how many devices you will need to support your cameras properly.
Storage Space
When planning for storage, you may want to consult with your IT department or an industry professional for guidance and advice. You must consider the number and type of cameras you need to support and how long you need the video to be retained. Proper storage abilities can make or break a quality surveillance system.
Power & Cooling
While often overlooked, power and cooling systems play a crucial role. Large scale video systems require a lot of equipment which need power for functioning, air conditioning to prevent overheating, and a UPS to safeguard from power outages or surges. Without these things, the best security systems would not be able to function properly.

It used to be common to see security guards monitoring public areas such as parking lots or building entrances, but, these days, the prevalence of security cameras is growing. Our means of surveillance is transitioning from human surveillance to networked devices. While some areas have added security cameras to complement their guards, others rely on comprehensive security systems.
There are numerous reasons why network security cameras are becoming more widespread. Aside from the covert nature of security cameras, technology allows us to do more with fewer risks. Rather than potentially putting a person’s life in danger, you can monitor your surveillance feed remotely and be aware of what is going on in various places. This will enable you to react in a timely manner and as safely as possible.
Some may oppose the implementation of security cameras for fear of an invasion of privacy, but they fail to acknowledge that other platforms that are seen as more acceptable can pose a threat. For example, loyalty programs often track and record your purchasing history and can be linked to your image through facial recognition technology. And think about how ads are becoming more tailored to the viewer’s interests. Common things like mobile phones, social media, credit cards, and more can offer data and insight about a person.
In comparison, surveillance cameras would simply be used to monitor public areas to improve safety. When crimes occur, footage can provide evidence, as well as paint the picture of events leading up to the incident.
Mass CCTV coverage has been achieved in cities like London and Melbourne. In some British cities, traffic light operation has been used to prevent criminals from escaping by car. This shows that networked devices can work together to increase safety and security.
There are obvious risks and benefits when it comes to networked devices and data collection. What are your thoughts on the use of connected devices and the Internet of Things in terms of security and surveillance? Do you think more cities will follow London and Melbourne’s lead and adopt a mass surveillance system? Share your thoughts with us on Facebook, Google+, Twitter, Vine, and Pinterest.

It’s true – surveillance footage can provide beneficial evidence when trying to prosecute and charge criminals. However, a better way to utilize security camera resources is to actively monitor the live feeds, which, in turn, can lead to improved response times and increased safety.
That is precisely what a new security operations control center (SOCC) in Washington is aiming to do. Opened in November of last year, the Metro Transit Police Department (MTPD) is using this new center to solve and prevent crime within the public transportation system.
Within the SOCC, surveillance footage is displayed from a large projector onto the front wall. Suspects’ photos are displayed on flat-screen televisions around the room and there is a police bubble that overlooks the floor. In the police bubble are dispatchers and call takers who log emergency complaints and text tips and relay the information to officers in the system.
The same operations were previously offered, however, not housed in the same room. Now that all teams are gathered together into one area, communications are faster and more efficient than before. And with a price tag of $3.6 million, this fruitful investment is proving its worth.
With a comprehensive security camera system, authorities are able to effectively monitor all areas public areas. When crimes occur, witness statements can be corroborated with surveillance video, providing a solid case against criminals.

As we ease into the New Year, there are several technology trends to watch. The Internet of Things has been on the radar for some time now, and more and more devices are becoming connected.
In terms of security, network IP cameras are nothing new. However, the influence of IoT and other technologies is having an interesting impact on security and surveillance. Here’s what we can expect, or hope for, in 2016.
IoT
As mentioned, the IoT devices remain in the spotlight. In terms of security, IoT-based systems will need to provide easy installation and maintenance, while catering to the specific needs of the user.
With an IoT-based security system, you may be able to incorporate other unrelated devices for an all-encompassing system. Combine your video surveillance with things like smoke detectors, gas sensors, or access control panels to monitor your home or property. Also, the IoT will enable video surveillance to expand its applications far beyond loss prevention. For example, your network IP cameras can be used to analyze traffic patterns and crowd behaviors in real-time.
However, as we continue to connect and share video and data over our networks, we must also think about reinforcing our network and cyber security.
Security as a Service
The Cloud is making its mark and will begin to play a more important role in security and surveillance. Not only can businesses utilize Security as a Service, where systems are managed remotely, but the Cloud offers more secure and cost-effective data storage. Archived video and data can be stored longer while being easily accessible as necessary.
Big Data
Thanks to security cameras and surveillance, video is becoming the fastest growing type of data. Aside from security purposes, surveillance video can be used for business intelligence. We can expect to see improvements for video management systems (VMS) to search and filter big data for relevant footage or information.
Wireless
Going wireless has played a significant role in our everyday lives already (ex. mobile phones and Wi-Fi). The same convenience has been applied to security systems, as whole security networks can be managed remotely through mobile phone and devices. Complicated software on stationary PCs is no longer necessary, making it easier for businesses to employ a more affordable and convenient security solution.
Details
We want everything to look sharp and clear, which is why technology continues to improve megapixel resolutions and technology. Some existing trends include the 4K ultra HD, which offers four times the resolution of HDTV 1080p. While analog CCTV cameras may work for some, most others will be attracted to the new and improved technologies and devices.
Analytics
In the coming year, we will also see an increased use of video analytics, for both security and business use. Video surveillance will expand its repertoire, becoming useful for more industries such as advertising and marketing.

New technologies are always emerging, and consequently, businesses can benefit in many ways. One of the benefits comes in the form of improved video surveillance. New imaging technologies help to enhance our monitoring capabilities. Discover the different ways that these new technologies can impact business surveillance for the better.
Situational Awareness
In order to cover a large area, businesses may opt to install multiple cameras. However, the implementation of numerous cameras can become costly. Using PTZ (Pan/Tilt/Zoom) cameras can be helpful, but over time, coordinates may become inaccurate and, thus, ineffective.
However, things like panoramic cameras, increased megapixel resolution, and digital PTZ help to improve image quality and viewing range for more comprehensive monitoring. Surveillance video becomes more effective with the use of video analytics and smart motion detection. As a business, you are able to extract useful customer information and be alerted of unusual activity.
Applications
These new technologies improve both indoor and outdoor surveillance. In the case of varying backlight conditions (ex. near entrances or windows), there is wide dynamic range (WDR) and super dynamic range (SSDR) to enable better images. With optical zoom, digital image stabilization, and even fisheye cameras, security cameras are able to capture more. The fisheye cameras are especially helpful in transportation as they can oversee passengers or watch the road ahead. The distorted images can be adjusted for different views and angles.
Cost
Budgets are always a concern, so when it comes to security systems, users look at the total cost of ownership (TCO) and return on investment (ROI). With so many options available, and more emerging frequently, it’s hard to determine which is best for your business. When deciding between upgrading to a full IP system or a hybrid system, it may be wise to go with the latter. Hybrid systems enable you to utilize your existing equipment while trying out new equipment. The new 1280H analog security cameras boast CMOS megapixel sensors and may be reason enough to choose a hybrid surveillance system.
Integration
With advanced technology comes compatibility with a number of third-party apps to enhance your system. There’s an app for nearly anything you can think of, and if there isn’t, it won’t be long. With that said, if your surveillance system is missing features and functions that you wish you had, you can find apps that enable these functions and are compatible with your system. Aside from adding to your system, apps can help with analytics, alerts, and business strategies.

Hospitals work hard to ensure that they provide a clean and safe environment for patients, visitors, and staff alike. From emergency room visits to hospital admissions, safety precautions are in place to protect everyone involved in the process. While these safety measures are valuable and mostly effective, the addition of security camera technologies can have a positive, lasting impact.
Introducing closed-circuit televisions (CCTV) in hospital and health care settings helps to enhance the safety of patients and workers. One obvious benefit is that being monitored often influences behavior for the better. Workers will be more conscious of their job, helping to eliminate potentially life-threatening mistakes. Unfortunately, unintended retention of foreign objects (URFOs) and hospital acquired infections (HAIs) occur more than they should. However, with video surveillance, these instances can be greatly minimized.
Another useful tool is third-party remote video auditing (RVA). Real-time RVA can help to ensure that hand hygiene and surgical safety checklists are being properly performed and executed. The cleaning techniques of medical devices must be done thoroughly and correctly to minimize the transmission of germs. For example, improperly cleaned duodenoscopes helped fuel the outbreak of carbapenem-resistant enterobacteriaceae (CRE) infections earlier this year. With real-time RVA, cleaning and sanitation techniques can be monitored to ensure that another outbreak does not occur.
RVA technology introduced into the ER can increase patient flow to intensive care units (ICU), labor and delivery/C-section areas, and endoscopy. The ability to monitor protocols, address issues, and improve patient services will eventually lead to happier, healthier patients and more lives saved.

Security camera systems, whether installed at home or in public places, are growing in popularity. There are numerous surveillance solutions available, most of which boast convenience and affordability. An attractive trend is wireless security cameras because they are relatively easier to install and maintain. However, just because you can do it yourself, doesn’t necessarily mean you should. Before installing your wireless security cameras, take a look at these common mistakes so you can avoid them.
Number Of Cameras
You may think that investing in a single PTZ (pan/tilt/zoom) camera will save you money because it has capabilities to expand your viewing range. Unfortunately, this camera may not get all the angles, and zooming in and out may not always produce the best picture. Instead, purchase enough security cameras to cover the different areas you wish to monitor around your property.
Positioning
Aside from installing enough cameras, positioning plays an important role in adequate surveillance. Things to consider are lighting conditions and possible obstructions. You don’t want your video footage to be washed out from too much light during the day, nor do you want any branches or bushes blocking your view.
You should also be mindful of placing your cameras where there is reliable Wi-Fi signal. Without it, your live feed could be choppy and may not be connected at all times. If the Wi-Fi signal is poor in an area where you need a security camera, there are Wi-Fi extenders that you can purchase, or some security cameras have these technologies already built-in.
“Wireless”
Because these cameras do not need to be physically connected to a router or Ethernet port, they are considered wireless. However, the power source is a different story. While most wireless security cameras are powered by batteries, others need to be plugged in. If that is the case with your cameras, be sure that power outlets are close by and accessible.
Password Protection
Since your wireless cameras will be connected to your network, it’s better to be safe than sorry. Your network should have a secure encryption configuration and a strong password to access it. Aside from that, your cameras should have specific passwords that are necessary to input during set up and installation. Most cameras come with default usernames and/or passwords, but it is pertinent that these be changed immediately to prevent hacking or unauthorized access. Passwords should be complex, but relatively easy for you to remember.
Remote Access
If you are looking to remotely access your surveillance feed, you will want to make sure that your wireless security cameras provide that option. More specifically, determine how you want to access your feed (ex. via web browser), and double check your cameras specifications to find out whether this is possible or not. Also, you will want to check the compatibility with your devices (ex. supports iOS, Android, or both).

The presence of security cameras often deters people from behaving badly and provides evidence if and when a crime occurs. Most businesses employ video surveillance for loss prevention purposes. However, as surveillance technologies get smarter, video surveillance can play a larger role.
Surveillance data can provide a wealth of information for different industries. For example, in retail, not only do security cameras help loss prevention, but surveillance footage can hold the key to increase sales and improve the shopping experience. Video surveillance data can replace “mystery shoppers” as a more effective avenue of collecting consumer data. For the transportation and shipping industry, surveillance analytics combined with RFID tags can help track cargo, lower operational costs and improve traffic flow.
To achieve such excellent benefits, businesses must seriously consider an effective storage solution. In order to get substantial results, studies must evaluate data over long periods of time, forcing business to get smarter about video surveillance data storage. When choosing the appropriate storage method, the main components to consider are performance, access, and cost.
Because high quality equipment can be costly, considering proper surveillance storage often goes by the wayside. This should not be the case if business analytics are your focus. For an effective system, your means for storage must be able to handle high traffic and high bandwidth without dropping data. If your cameras have high definition, the bandwidth load will only increase from there. For effective performance, your storage should be able to upload, process, and allow access as quickly as possible.
While you need a strong performing system, you must balance your cost. You can spend your entire budget on a storage system that can perform appropriately, but may lack functional organizational. On the other hand, you can cut costs by implementing more affordable means of storage, but again, organizing and accessing this data can become a nightmare.
Your best bet when it comes to storage would be to employ a high-performance, tiered-storage infrastructure that can be managed as a single system. A tiered structure allows data to be stored as a cost-effective medium. The files will be stored based on user defined policies, allowing you to be in total control of your data. Costs are lowered and data is analyzed more effectively.
Business analytics of surveillance data can afford your business with a multitude of benefits. But you can only capitalize on these benefits with an effective storage system. Pay close attention to your options and evaluate your needs before making a final decision.

Security cameras are great for monitoring areas and deterring crime. But how can video analytics take surveillance a step further?
In the beginning, the promise of video analytics and its capabilities caught the attention of many, but sadly, its performance fell short. But over time, these technologies have improved and video analytics are now offered more confidently. Features such as heat mapping and license plate recognition are delivering what they promise and consumers are pleased with the outcomes. Consequently, security cameras and video analytics are finding themselves more useful than ever in different environments.
For retailers, security cameras provide many benefits. Not only do they help to prevent shoplifting, but are also allowing business owners the ability to analyze customer behaviors in relation to traffic, shopping patterns, and more. Luckily, with these advancements comes a system that is easier to use and deploy.
Video analytics can also help businesses improve their customer service by introducing more checkout personnel when lines get too long, or providing low inventory alerts so that stock can be replenished and customers can get what they need. Because this type of data and marketing metrics is ever useful for business owners, we will likely see an increase in demand and implementation for these types of video analytics.
As with any major purchase, it is wise to do research and find which solution works best for you and your needs. For those who are employing these technologies, how is it helping your business?

We are all too familiar with that panicked feeling you get when your mobile phone battery is in the red zone with no charger in sight, when our car batteries die at the most inopportune times and places, or when there is an unexpected power outage or blackout. We rely heavily on power sources for many things. But why not get our power and energy from what we already have and allow our devices to power themselves?
A team led by computer science professor Shree K. Nayar at Columbia University realized that an image sensor of a camera is capable of more. With lots of time, thought, and careful execution came the first self-powered camera. Running on its own power, this camera can produce an image each second, indefinitely.
Basically, how this works is that the image sensor not only works to capture the image, but at the same time generates power with the available light source. More technically, the photodiode measures the incidence light level to capture the picture and then converts that into electrical energy to continually power the camera.
Albeit, the image sensor produces a mere 30×40 pixels, but the amazing part is that as long as there is a light source, this camera can continue recording forever (ideally). When the camera is not in use, it can power other devices, like a watch or a phone. It can even take advantage of rechargeable batteries’ harvesting ability.
It is still in the early stages, but as this technology develops, it can change the way we power our security cameras and other devices. What are your thoughts on this topic? Share with us on Facebook, Google+, Twitter, and Pinterest.
