Outdoor Analytics With GPS Available on SightSensor Cameras

SightLogix : 24 March, 2010  (New Product)
The SightSensor range of cameras from SightLogix includes all-weather thermal variant with built-in analytics and subject tracking capability
SightLogix, a supplier of outdoor Video Analytics systems for area and perimeter security, is displaying Visible and Thermal SightSensor intelligent video cameras at ISC West this year. Long and wide-range outdoor SightSensors provide a high probability of detection with low nuisance alarm rates, and can operate in all weather and climate conditions, including rain, snow, humidity, sand and temperature extremes. Each SightSensor camera incorporates either a visible or a thermal imager, lens optics, electronic stabilization, on-board image processing, Video Analytics software, camera control, and geospatial target tracking, all sealed inside a rugged NEMA 4X nitrogen-purged housing.

"Unlike indoor analytics, which are designed to operate in static environments, the outdoors is constantly changing," said John Romanowich, President and CEO, SightLogix. "Our systems have been designed to recognize and address the unique variables associated with outdoor surveillance, and meet our customers' needs for an outdoor solution that is cost-effective, reliable, and easy to use."

Multiple on-board digital signal processors (DSP) communicate directly with the image sensor to analyze the scene details of each video frame for better accuracy and extended range. This extra processing power supports electronic image stabilization to eliminate video shake, while compensating for low and changing lighting conditions in the visible model. The processing power is also used to accurately detect objects in a background of environmental movement such as leaves, shadows from clouds and wind-blown objects. "Without effective image processing," said Romanowich, "the only way to prevent nuisance alarms from these outdoor variables is to lower sensitivity of the system, which directly impacts camera range and detection accuracy."

An additional element that SightLogix considers essential for accurate Video Analytics outdoors is geo-registration. SightSensor cameras are registered to the scene with GPS coordinates so they can accurately determine target size, bearing, and speed in order to filter out small animals and blowing debris, reducing nuisance alarms. SightLogix systems also use geo-registration to display the coordinates of detected targets onto a sitemap for situational awareness, and to steer PTZ cameras to automatically zoom and track detected objects.

By providing a high level of imaging processing, each SightSensor camera can cover wider areas or greater distances; as much as three times the coverage area of other surveillance cameras. This means that SightLogix systems require fewer cameras, reducing the supporting infrastructure (poles, trenching, networking, power, etc.) and associated costs. As a result, SightSensor cameras lower installation, infrastructure and overall project costs by one-third versus alternatives.

The cameras integrate easily with third-party video management, physical security information management (PSIM) and access control systems. Flexible and secure communications include 10/100 Ethernet with support for satellite, cellular, wireless (802.11 a/b/g) and full broadband communications, with AES 256-bit encryption and SSL protocol.
