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

The wireless glass break detector detects when different types of glass break and triggers alarms in real time. With advanced technology, it captures the low and high frequencies emitted by glass breakage, reducing the chance 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 various 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 failed update.
• The two-way wireless encrypted communication mechanism improves the security and stability of communication.
• With the wireless frequency hopping mechanism, the device will automatically switch to other available frequency bands when the original frequency band is interfered with by other wireless signals, to ensure stable communication.
