DEA7WL is a compact wireless entry alarm system which is easy to install in both indoor and outdoor. It is designed for both residential and commercial using such as garage door, shops, warehouse restaurants and farm etc. to alert you to the entry of customers and visitors. The system consists of a send/receive unit which transmits an IR beam across the doorway onto a prismatic reflector mounted on the opposite side. The beam is reflected back to the receiver to complete the circuit. When a person walks through the beam, the circuit is interrupted and this causes the alarm to sound an audible warning. The warning buzzer can be mounted in any suitable location. The package comes with a solar panel and rechargeable Lithium-Ion battery which enable the sensor to work outdoor that saves you the time and money of wiring.

Q: Can I use DC power supply with the sensor instead of the solar panel?
A: Yes, you can use our DOSS SM520 5V 2A power supply (web link), but you need to change it to 2.5mm DC tip (web link) instead.
