Dahua AirShield Wireless Door Detector

The Dahua AirShield Wireless Door Detector is a wireless opening detector for Dahua smart alarm systems. It consists of a sensor and magnet, triggering an alarm when an armed door is opened. It can also display the open and closed state of doors and windows in the DMSS app in real time.

Designed for indoor use, the detector is mainly applied in villas, shops, apartments and similar properties. It is suitable for monitoring entry points, internal doors or windows where open and close status needs to be reported as part of an alarm system.

The detector uses a reed switch and is designed for non-metal doors, with a movement distance of less than 40mm. It also includes a 1-channel dry contact input for an external zone, supporting additional flexibility within the alarm installation.

Wireless communication is supported through two-way communication, AES128 encryption and frequency hopping to help maintain stable connectivity. The detector also includes signal strength detection, tamper alarm, low battery alarm, test mode, cloud update and automatic recovery from update failure.

Powered by a CR123A battery, the detector provides up to 4 years of battery life when the external input type is NO, or up to 2 years when the external input type is NC or Pulse. It is bracket mounted, housed in a PC + ABS casing and designed for indoor operation between -10°C and +55°C.
