For example, you have configured temperature limit for the target, all areas with temperature
exceeding this configured threshold will be highlighted with specific colors. After receiving the
alarm, you can quickly determine the alarm source through the isotherm image.

5.3.1 Installation Requirements on Perimeter Protection
5.3.1.1 Site Selection
●
When installing the Camera, keep a depression angle (10°–40°) to avoid obstruction or overlap
between the targets caused by parallel view, which can reduce the false alarms and missed
alarms.
●
The recommended installation height is 3 m–5 m. (In the detection area, we recommended high-
point installation rather than low-point installation).
●
Install the Camera horizontally and firmly to guarantee the analysis result.
●
To get a clearer movement of the target, make the monitoring direction vertical to the moving
direction. Make sure that the target is continuously present in the image, and has crossing action.
Make sure that there is no obstruction in the detection area, and leave some space at both sides
of the rule line, otherwise the target might rush out of the image because of the fast speed.
5.3.1.2 Typical Scenes
●
When there is no obstruction around the perimeter, install a vertical pole (≥ 1 m) on the
perimeter, and then install the Camera on the vertical pole.
