BWA Technology: 3D real-time video analytics system with face localization

BWA Technology: 3D real-time video analytics system with face localization. Traditional „passive“ outdoor video monitoring systems do not provide sufficient resolution for the clear identification of faces, details of clothing and objects. The effectiveness of mega-pixel cameras in 24h-operation is often limited due to their lack of light sensitivity. The amount of data that is generated this way is unnecessarily large due to irrelevant picture areas and image details. Conversely, when using highly sensitive cameras in standard resolution, an excessive number of cameras are needed to monitor large areas. PTZ cameras may offer a possible solution, but then the higher number of operating personnel that is needed increases operating costs.

An ideal solution would employ PTZ technology to do all the discovering and recognition work, with humans doing the final analysis. BWA Technology may be onto something with their new active 3D video analytics system with realtime face localization.

Currently in the final stages of development and still with a little room to define the final feature list, the Direx- 4Scan will provide a compact automatic control system for pan/tilt cameras and speed domes which analyzes video content from up to four stationary cameras. It is expected to achieve market launch around August or September this year.

A unique method of triangular video analytics will allow three-dimensional modeling which, among other things, provides zone priority options, a number of tracking targets, moving profiles of objects, and automatic facial zooming. If several cameras are used, it will also be possible to process the „Person group segmentation“ scenario.

The system can be configured automatically on a local network. Upset up is done once and does not require any further readjustment or calibration. Only the camera assignment, the priority of the monitored areas and operating schedule need defining.

Leaving the technology to do the bulk of the work means that video analytics can be performed on up to four cameras. A smart, operator-free speed dome control will track several targets and provide facial zooming. Where regular patterns occur, a multi-zone scan can be scheduled via a timer. The entire system is very compact and, with due consideration to the security personnel, runs without a fan.

To integrate the Direx-4Scan into existing CCTV systems, four video outputs will be available next to the video inputs which forward data from stationary cameras. This allows easy cascading of several devices to analyze overlapping areas. It will be possible to control other dome cameras and to automatically observe areas of unlimited size.

The active video tracking system is therefore expected to be a perfect add-on for the new Direx-8D1 eight-channel video recorder. It includes integrated de-interlacing in real time recording at full 4CIF resolution with superb H.264/AME (Advanced Motion Estimation) performance – up to 40% more efficient video compression compared to H.264 Baseline Profile.

Visitors to Ifsec will be able to discuss the system‘s capabilities with BWA staff in Hall 5 at Stand 5A35. Input is always welcome from system integrators who are most often in the ‚front line‘ of video surveillance installations.
