5.7.5 Configuring Pan
Enable pan, the Camera can realize continuous 360° horizontal rotation at a certain speed.
●
The interval between pan circles should not be lower than the default value. High PTZ speed
might cause missing alarm (see the table below for PTZ speed and time). The coverage area is
area that the thermal channel covers. The recommended speeds offer reference for heat
detection only; for smoke detection, make sure that the picture is not blurred during pan.

cover the area to be detected.
