Dahua ARD512-W2(868), Wireless glass break detector, AirShield

Description

The wireless glass break detector recognizes when different types of glass break and activates alarms in real time. With advanced technology, it captures the low and high frequencies released when glass breaks, reducing the risk of false alarms due to ambient noise. It also features two external ports that can be connected to third-party wired detectors. 

  • Detects when glass breaks and activates alarms for different types of glass, such as tempered, double-glazed, laminated, reinforced, sheet and float glass.
  • Detects high and low frequency sounds simultaneously and uses algorithms to reduce false alarms.
  • Two-channel alarm input.
  • Cloud update and automatic recovery in case of a failed update.
  • The two-way wireless encrypted communication mechanism improves the security and stability of communication.
  • With the wireless frequency hopping mechanism, the device automatically switches to other available frequency bands when the original frequency band is disturbed by other wireless signals, to ensure that the communication remains stable.
