Wireless Home Doorbell & Security Alarm System
Our motion sensor alarm provides a solution to alert you the moment someone enters your property. It’s not only very convenient but also extremely affordable. When movement is detected, the Passive Infrared (PIR) sensor sends a wireless signal to the receiver from up to 280m/918ft away. Adjusting the receiver, you can choose to be alerted by a high or low chime or alarm tone, or instead, with just a silent LED flash.

Features:
It detects movements and sends a signal to the receiver from up to 328 feet (100m) away.
Alerts you when someone enters your driveway, walking path, doorway or store, porch, business, such as visitors, vehicles, intruders, animals or kids coming or going.
Advanced notice when someone or something enters before they surprise you.
Use it to monitor any area inside or outside but keep it protected from direct contact with the sun or rain, its wireless so you can place it anywhere in the house.
Notes:
Don’t mount the PIR sensor on direct sunlight spot (as moving heat sources would trigger the PIR) or in a location blowing wind frequently. When installing outside, it’s best to mount it at shaded location by your driveway, protected place with minimal changing temperatures.
Mount the sensor away from direct sunlight, such as under an overhang, covered area, or in a non-metal box.
Make sure the installation range is good. The user should test before install the alarm unit.
