What are the main security applications for embedded vision products?

Embedded vision products have been used in the physical security market for a number of years. The technology is commonly referred to as video content analysis (VCA) or intelligent video in the physical security industry. It is used in virtual tripwire applications, providing perimeter intrusion detection for high-risk facilities such as airports and critical infrastructure.
Typical projects use video analytics to generate real-time alerts when an object is identified and tracked through a pre-defined area. Operators, based in the central control room, can manage more video streams as they are not required to identify intruders purely from watching the monitors. Instead, the embedded vision product will identify and alert the operator when there is a potential security issue. It is then up to the human operator to decide how best to deal with the threat.
Other applications of embedded vision products in the security space include wrong-way detection and trajectory tracking. These types of algorithm can be used in airport exit lanes, where security managers want to identify people entering the restricted area from the main terminal. This responsibility has, historically, been given to security guards; however, embedded vision technology can reduce security guard costs for airport operators and increase the accuracy of the security system.

Other applications in the security market include behaviour recognition algorithms such as “slip and fall” and abandoned/left object detection. These applications are less developed than the perimeter detection systems, but will provide powerful tools for security managers over the coming years.


What are the primary embedded vision products used in security?

The primary embedded vision products in the physical security market are network cameras, encoders, NVRs, DVRs and intelligent appliances. The majority of products are supplied by established video surveillance vendors. These vendors either develop analytics in-house or embed third party algorithms from video content analysis software developers. Consequently, growth in the market is heavily driven by what these vendors decide to do and the extent to which they commit to intelligent video.

Over the last couple of years, the video surveillance market has also seen “low-end” analytics, such as camera tamper detection and video motion detection, become a standard feature on many vendors’ product ranges. These applications have developed from a distinct video analytics market, to a product feature used as a differentiator. “Low-end” analytics are embedded on cameras, encoders and storage devices.


Who are the main suppliers of embedded vision products in security?

The embedded vision product market for physical security applications is comprised of traditional video surveillance manufacturers, such as Bosch Security Systems, Honeywell and NICE Systems. These companies have made a strong commitment to the intelligent video surveillance device market.

There are also dedicated video analytics device manufacturers active in the market: VideoIQ and SightLogix are two examples of this type of vendor. ioimage was another dedicated VCA device manufacturer; however, it was recently acquired by DVTel, a video surveillance vendor active in the security industry.
