Radar with thermal cameras a.k.a Thermal radar

Francisco Feijoo - Tuesday, Aug 4, 2020

When we talk about perimeter protection, one the most used devices are thermal cameras (or Infra-red IR cameras), able to form gray-scale images that represent the environment temperature.

These images are much less sensitive to sudden lighting changes and in general offer information that is easier to analyse and generate less false alarms than conventional color cameras. Also, these sensors are passive, which means that are undetectable by others.

At Buavi, we have developed an innovative system, that is able to simulate the doppler effect that makes radar work, using only thermal cameras. Any thermal camera connected to the SharpView platform can generate tracks as if was a radar.

How does it work?

Using a geo-referenced fixed lense thermal camera we can detect any movement on the scene by analysing the images.

These movements are positioned in the map providing latitude and longitude coordinates (GPS).

Once the threats are located, a Pan-Tilt-Zoom (PTZ) camera is directed to verify the detection fully automated (without user intervention).

In the event of getting more detections than PTZ cameras, the system alternates between threats to register the best possible evidence.
