This mobile entry detector is ready for action in no time at all thanks to its power supply via 4 x AA batteries. The visual detector works like a light barrier, triggering a gong signal whenever the sensor detects a movement. You can adjust the volume of the gong signal individually using a sliding switch. At maximum signal strength, you can also use your entry detector as a mini mobile alarm system. For constant stationary operation, simply connect an external mains adapter with 300 mA.
