FAQ
1. What could cause the device to be falsely triggered?
Small animals entering the detection area.
Direct exposure of the sensor to infrared radiation from sunlight, car headlights, or incandescent lamps.
Sudden temperature changes in the detection area caused by heating or cooling devices.
2. Why is the device failing to detect human presence?
Obstructions like glass, acrylic, or walls between the sensor and the target, which block infrared signals.
The target is either stationary or moving too quickly.
The ambient temperature is close to human body temperature.
3. How does Detection Duration work?
The SNZB-03P reports motion immediately when someone is detected and can trigger lighting via scene automation.
By default, Detection Duration is set to 1 minute, meaning it reports no motion 1 minute after a person leaves. This can be used to turn off lights via automation. The minimum configurable detection duration is 5 seconds.
