Dahua’s combination of Radar & Video Detection Systems raise Perimeter Protection to a new level. Although conventional Perimeter Intrusion Detection Systems (PIDS) might be useful, each technology has drawbacks as well. Systems of buried cables and fences might produce false positives or false negatives detections and are extremely expensive to deploy. Even perimeter security systems based on cameras are susceptible to environmental hazards such deep water, snow, fog, and intense rain. Additionally, tiny animals, leaves, and swinging branches may create false alerts on some camera systems, making them susceptible.

Many of these issues are solved by Dahua's integrated Radar & Video Intrusion Detection Systems, also known as Radar Perimeter Protection Solution. Radio waves are used by radar (radio detection and ranging) to determine the proximity, angular relationship, and speed of objects. It comprises of an electromagnetic wave transmitter, a receiver, and a processor. The position and speed of an item are revealed by the radio waves from the transmitter that reflect off it and return to the receiver.

Multi-dimensional Protection

A "multi-dimensional" solution is offered by Dahua's Radar Perimeter Protection Solution. Security radar, which is used to find targets in the monitored region, is the first "dimension." Once the target has been identified, radar may follow it to collect information on its direction, speed, and distance. High-definition, intelligent video is the second "dimension."

Essentially, the radar identifies a moving item while the camera gives visual confirmation of the detection, allowing control room personnel to follow and zoom in on the target to receive a close-up view of the thing. For certain application scenarios, such as forest regions, lakes and rivers, and water reservoirs, a third "dimension" of thermal imaging can be introduced.

The advantages of Radar Perimeter Protection Solution include:

• 24/7 operation, even in difficult weather conditions
• High level of detection accuracy and very low false alarm rates
• Large and wide area detection
• Active target detection
• Dahua multiple PTZ cameras may be linked to a single radar or multiple radars to a single PTZ with the use of clever front-end control.
• Centralized configuration and management of the combined radar/video tracking system on Dahua’s DSS Pro platform

Types of System

Radar-only system: This is best suited for applications that simply need the detection of perimeter crossings, particularly in those involving frequent perimeter crossings.

Radar with multiple PTZs: Linkage tasks may be performed by using numerous PTZ cameras at once in the radar's monitored region. According to the target's entry speed and distance into the monitored region, the radar distributes control of the camera.

Several radars with a single PTZ: To actualize whatever is detected, three or four radars are combined into a 360-degree region and coupled to one PTZ camera, saving money on many camera installations.

The Radar Perimeter Protection Solution from Dahua is particularly good at keeping an eye on vast areas with plenty of activity, such rivers, vital national infrastructure sites, multi-lane road networks, and sizable high-end locations like resorts and parks.

Conclusion

As is obvious, combining video technology with radar results in a powerful surveillance and detection tool that is more effective than the sum of its parts. Users of such systems may rest easy knowing they have the finest defence against unauthorized access and activity on their sites.
