Product Description
The Dahua Wireless Magnetic Contact, ARD323-W2(868S) has a strong signal detection and is equipped with a temperature sensor. With a bidirectional communication technology, this device offers the possibility of updating in the Cloud and in case of a failed update you get automatic recovery of the information.
Furthermore, the integration into the DMSS mobile application makes it possible to view and report any changes in real time. So if the door is open, an alarm is automatically activated thanks to the magnetic sensor, which sends the signal to the hub.
