Radar technology is inherently suited for wide area surveillance. It can quickly sweep a full 360 degrees, analyzing the return signals to determine if there is any movement in the area. It operates in all weather and lighting conditions, and can be designed to have an extremely low false alarm rate.
It can work over land as well as water; it can detect a variety of targets: i.e. crawling, walking and running people, and moving vehicles. A radar detector can pinpoint the exact location and path of travel of the target(s). A radar surveillance system can also provide masking of areas where detection is not required, in both range and angle, so that complex installations can be masked appropriately to avoid nuisance alarms from areas where activity is allowed.
This system uses modern radar technology for wide area detection of objects which are moving, and then using the precise location information from the radar to point a camera at the object. The operator is then presented with the location, direction of travel and identification, including the number of potential intruders, all in a matter of seconds. This allows the operator, at his console, to quickly have the detailed information he needs to determine an appropriate response.
The system can continue tracking the intruder with both radar and camera, even after a perimeter breach, to provide real time assistance to the response team.
Radar detection systems do require line of sight to detect an object, which means that it is sensitive to terrain undulations and remote buildings. Unless the detection system is deployed in a completely open space it is better to install multiple low power units than a single high power version.
A major advantage of radar is that it can see beyond the perimeter fence and be used as an early warning device creating an amber alert, for example, if a person is detected approaching the fence line. The detection areas within the 360 degree sweep can be defined and configured for different reactions to detection. Some areas can be masked completely whilst other can generate a full alarm.
After an event has occurred the operator can determine the nature and extent of the intrusion whilst tracking their progress within the protected area, both on screen via the radar and with the fully functional CCTV / thermal imaging support
