Achieving Effective Perimeter Security
When it comes to perimeter security, you want to have timely, believable alerts with video of the alarm. This lets you tell right away what’s happening outside of your site, at all times. When you know the nature and location of a perimeter security alarm, you can make a fast and appropriate response, and stop intruders before any damage can happen. While there are several options for detecting outdoor intrusions, thermal cameras with video analytics have become the solution of choice for perimeter security applications. Smart thermal cameras operate day or night, and can detect intruders automatically, even over large outdoor areas in complete darkness.
A number of other solutions, such as coax and fiber fence sensors, microwave, seismic sensors and radar can provide some level of perimeter security. However, smart thermal video provides many important advantages. When a speedy response is needed, only smart video perimeter systems provide an intrusion alert along with video, so you know the location and nature of an event as it’s happening.
Smart thermal video cameras, which were once only used for seeing in the dark, now detect intruders under all conditions, including rain, humidity, fog and bright sun, and no longer create blurry images, excessive nuisance alerts or mis-detects. The SightLogix system has been designed to accurately detect targets in a wide-range of outdoor environments while addressing the core issue of nuisance alarms.
Specifically, SightSensor smart video cameras have a high degree of image processing for addressing all the challenges associated with outdoor security. This includes stabilizing the image to stop camera motion from wind or vibrations, while filtering out the movement from trees, leaves and small animals, and yet accurately detecting people when a security rule has been violated.
Longer Ranges and Coverage Areas Decrease Costs
When smart video cameras use a large amount of video processing, they can detect intruders over great ranges. This means fewer cameras are needed, lowering infrastructure requirements accordingly. The cost savings realized from extended camera range can be as high as 50 percent, stemming primarily from elimination of extra cameras and poles, construction, trenching, power and network connectivity. These infrastructure costs can be the most expensive portion of an outdoor video deployment, and using longer range cameras keeps them low.
Situational Awareness and Perimeter Security
Achieving security awareness also depends on knowing where an alarm has occurred and what it looks like. This is why SightLogix smart camera systems are geo-registered to the scene when they are first installed. Georegistration means that the camera knows the actual size, speed and direction intruders, which leads to greater accuracy. Georegistration is also used for two additional features unique to SightLogix: The system can project the location of the alarm as it moves onto a site map, and can also automatically steer PTZ cameras to zoom and follow the intruder in real time.
