The most commonly used sensing method for fast rolling shutter doors is radar sensing. Because it can both automatically open when vehicles pass by and allow pedestrians to pass through, why sometimes when there are moving objects entering the radar sensing fast rolling shutter door range, but the radar is not working and cannot achieve automatic door opening?
1、 Sensitivity: It is possible that the sensitivity is too low and the detection range is too small, resulting in the inability to detect moving objects when passing, and the fast rolling shutter door cannot receive the opening signal. The detection range sensitivity is adjustable.
2、 Installation height: Generally, the installation height of a regular radar is within 4m, while for a regular 1-3 meter sensor, all moving objects are automatically lifted and lowered by the quick door. If it is higher than this height, it is recommended to install other radar models.
3、 Antenna angle: There is an issue with the antenna angle inside the radar, which makes it possible to adjust the detection angle when the quick shutter door is opened normally.
