DHI-ARD812

Wireless keyfob

• 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.

Connection to Hub through RF or network communication. > 16 alarm inputs, 4 relay outputs. > 2 auxiliary power outputs with a maximum power of 24W for powering wired detector and siren, and support overload and short circuit detection. > POE, AC power and rechargeable battery (optional) three power supply options.

•  Supports alarm video verification through integration of the IPC with the hub.
• Images can be remotely and quickly transferred from the PIR-Cam to the device.
• Features voice call alarm.
• Supports wired and AP network configuration methods, which makes it easier to add the hub to apps and to switch to the hub's network.
• Supports multi-network redundancy for Ethernet and Wi-Fi to ensure the network remains stable and reliable.
• Supports two-way communication and frequency hopping to make communication with wireless peripherals stable and reliable.
• Features cloud update. You can also remotely update the device and wireless peripherals on the mobile app.
• Offers a dual backup system, and uses auto recovery when an update fails.
