5.2 Operating Modes
The device features three distinct operating modes:
- Welcome Mode: When motion is detected, the device will play a specified 'welcome' sound. This is ideal for entryways in shops or homes.
- Smart Mode: Similar to Welcome Mode, but the detector will not activate for the first 3 seconds after sensing motion (LED light on). This allows for brief passages without triggering the sound.
- Alarm Mode: Upon detecting motion, the device will emit a continuous, loud alarm sound. This mode is designed for security purposes. To turn off the alarm, press the Mode button. The alarm typically sounds for around 20 seconds.
