HIGH SENSITIVITY: Our wireless home alarm systems are equipped with highly sensitive infrared sensors that detect movement quickly and accurately. The range is 6 to 8 meters. EASY WIRELESS INSTALLATION: No wiring is required. Simply attach the doorbell's infrared sensor to the wall (with adhesive tape or screws). It detects movement in its vicinity, whether in the driveway, on the porch, at the door, in the shed, in the office, on the sidewalk, by the pool, in the shop, and much more. LONG RANGE: With a distance of up to 280 meters between the receiver and transmitter of the front door alarm system, you can place the sensor at the ideal distance from the receiver to ensure effective monitoring. The separate 40mm speaker has a maximum volume of 95 dB. 22 RINGTONES AND 8 GREETING RINGS: The receiver features 22 different ringtones, from melodic sounds to a simple buzzer, as well as 8 greeting chimes for retail businesses. VERSATILE APPLICATION: The outdoor motion sensor is suitable for mailboxes, driveways, galleries, gates, doors, passageways, apartments, offices, hotels, shops, and many other indoor spaces. The non-weatherproof motion-activated doorbell is not suitable for outdoor use. It can also be used for child safety and as a reminder for the elderly. TWO POWER OPTIONS: The motion sensor can be powered via USB cable or batteries. The main unit requires 3 x 5-cell batteries, and the sensor requires 3 x 7-cell batteries. The batteries should be replaced every 5 to 7 months. Note: Batteries and USB cable are not included.
