The traditional role of the camera in border and perimeter security applications is to provide accurate and rapid assessment of alarms through high quality images, both day and night, and in a variety of lighting and weather conditions.
Video content analytics embedded in Lumenera's Li-series cameras improve these conditions by providing specific and timely alerts to the control room based on the images from the cameras.
Video analytics and intelligent cameras
Lumenera's intelligent camera products use ObjectVideo's OnBoard™ embedded video analytics software. Using a simple graphical user interface, one may configure specific rules related to the position and behaviour of persons, vehicles, or objects that can be used to track alarms and/or log them. Basic examples involve the appearance or entry of a person or vehicle, as well as defining tripwire rules that specify the forbidden direction of travel. The same capabilities can be used to count persons or vehicles, or to measure the time or speed of travel.
Video analytics is embedded in the camera operating at the network edge to provide a much more scalable and cost-effective system, with lower latency between real-world events and operator alerts. Accurate rules-based alerts provide low nuisance alarm rates and shorter response times.
Rules can specifically identify the location and behaviour of people, vehicles, or objects relative to defined areas. Easy-to-use filters are available to exclude alarms due to nuisance factors, such as small animals, disruptive weather, or falling leaves.

Video analytics serve as an aid to the security control room personnel by reducing operator fatigue, increasing motivation, improving decision making, and operator response time. By providing an automated display highlighting a potential intrusion alarm, rules-based content analysis embedded in the camera reduces false alarm rates, and provides automated alert display and logging. The presence of a highlighted visual display of a specific alert helps the person on duty take quick and appropriate action.
Lumenera's Li045 cameras
Lumenera's Li045 cameras use the Pixim Orca chip set to provide rapid and effective responses to challenging and ever-changing high-contrast lighting situations. This has a broad applicability to both outdoor and indoor situations that may include bright daylight or spotlights as well as shadows.
The same Pixim image sensor technology allows one to view the interior of vehicles which are always shaded, in a variety of conditions. The level of JPEG compression can be specified by the user or set automatically, depending on image quality, bandwidth and storage requirements.
