Merely enclosing an indoor video analytics solution inside an outdoor casing is not sufficient to achieve the standards of performance and reliability required by automated outdoor surveillance.
The SightLogix intelligent video analytics system is the only solution engineered specifically to meet the unique challenges of outdoor perimeter surveillance.
Lighting: The SightLogix visible sensor solution offers backlight compensation and automatic white balance adjustments to compensate for the changing position of the sun and other external lights, such as vehicle headlights. The infrared sensor consists of a fixed position, long-wave infrared camera.
Motion: High-powered multi-chip processors integrated with the SightSensor camera optics allow the camera to distinguish motion caused by wind, shadows, or vibration from the motion of an object or person crossing the field of view. This advanced image stabilization supports reliable detection of very small images at much longer distances possible with standard cameras.
Temperature/Humidity: The SightLogix SightSensor is housed in a sealed, nitrogen-filled enclosure. This enclosure, along with an optional heater for extreme cold environments, supports extremes in temperature from -22°F to 158°F. The enclosure is rated for NEMA 4X, ensuring that the camera will be undamaged by rain, sleet, snow, windblown dust, splashing water, hose-directed water or the external formation of ice on the enclosure.
Coverage: With a resolution approaching 4 Megapixels, the SightSensor can accurately detect an intruder at up to 1,500 feet away--three times the distance of a typical camera. Increasing the distance by three increases the area covered by the camera approximately ten times. More area covered by each camera means fewer cameras, and lower installation and maintenance costs.
Bandwidth: Because the video processing is completed at the camera’s edge, SightSensors can digitally encode and dynamically adjust the sensor output bandwidth to fit into virtually any channel bandwidth desired. These unique features make the SightLogix video quality and alarm accuracy completely independent of the bandwidth and Quality of Service (QoS) of the communication channel. As a result, the system can communicate over virtually any wireless method.
