Based on the PIR working principle, users cannot set up PIR detection zones on the Reolink battery-powered cameras as they use the PIR sensor to detect motions.

Applies to: All Reolink battery-powered cameras.

In PIR detection, motion is detected by means of a PIR sensor (passive infrared sensor). The PIR sensor detects emitted infrared energy from objects (humans and animals, but also cars) in the form of heat.
On Reolink battery-powered cameras, there is a PIR sensor on each side of the camera and the camera detects the temperature differences between the two sides to detect motions. The camera will be triggered as long as there's a temperature difference between the two sides. 
Due to the working principle of battery-powered cameras, the function of the PIR detection zone is not available.
