Similarly, there is an increased use of tying analytic cameras to conventional PTZ cameras, usually via GPS coordinates, to create real-time tracking systems. Since most video is used in a forensic mode, video content analysis can be quite useful in intelligent management of storage resources, including content sensitive resolution and frame rate adjustments, length of storage, and implementation of archiving and duplication policies. From the operator standpoint, awareness of potential events, not yet classified as alarms, can be increased through decisions made about what types of occurrences are worth highlighting.
Thanks to Moore’s law, we have every reason to expect continuing advances in processing power at the camera and at central servers. In parallel, the imagers in surveillance cameras will become increasingly capable. Combined, this will lead to improved performance, lower cost and more intelligence at the camera.
This greater horsepower and intelligence has several ramifications. Increasingly, the rich detail derived from megapixel and high-definition cameras will be exploited for better overall performance. Next, as image quality becomes less of a differentiator for camera manufacturers, look for those devices to serve up new flavors of metadata that can be exploited by VMS and the other systems mentioned earlier for more intelligent, more effective, and faster search of stored video, and more real-time search and tracking capability.
It is reasonable to project that we will see more application-specific and market-specific products due to better information capture and processing. Those who process this data in centralized systems have the opportunity to develop customized algorithms based on different types of metadata flowing into the system; and they can execute them with increasingly powerful processors, providing advanced search functionality, contextual search, correlation with other events and real-time forensics. Learned systems that get smarter over time will not only provide better performance, but easier installation and calibration.
Ultimately, the utility and business value of surveillance systems will be enhanced, enabling expanded use of services such as cloud monitoring, and tighter integration of other business and building functions.
