Introduction
Outdoor video surveillance systems are used to detect and identify people in a variety of different environments. Identifying people in a video frame can be extremely accurate in a controlled setting. But, many of the locations that video surveillance systems get installed in are noisy environments. Additionally, capturing and recording camera data can be a very power-intensive process, which drains battery life for battery-powered systems.
Using radar to detect movement and alert the video surveillance system increases battery life by keeping the camera off in times when it is unnecessary. Radar outperforms similar presence detection technologies such as PIR, ultrasonic, or just the camera operating alone, by reducing the number of false positive detections. This leads to longer battery life for camera systems.
More than just saving battery power, the radar also adds functionality to the system. Its precise distance measurements keep the camera from unnecessarily recording neighbors as they pass on the sidewalk. Its long range detects people at 15+ meters. It can detect people and objects in conditions that are challenging for cameras such as darkness, glare, smoke, fog, and rain.
