ARD512-W2(868)
Dahua Wireless Glass Break Detector
> Detects when the glass is broken, triggering alarms for different types of glass such as tempered, double-glazed, laminated, wired, plate and float glass.
> Detects high and low frequency sounds at the same time, and uses algorithms to reduce the occurrence of false alarms.
> Two-channel alarm input.
> Cloud update and automatic recovery from update failure.
> The two-way wireless encrypted communication mechanism improves the security and stability of communication.
> With the wireless frequency hopping mechanism, the device auto matically hops to other available frequency bands when the original frequency band is being interfered with by other wireless radios, to ensure communication remains stable.
