ARM320-W2
Dahua Wireless Input Expander
> Six types of alarms: Intrusion, medical, fire, emergency, gas, and tamper.
> Connects to external power supplies.
> Triggers alarms when the device is moved.
> Alarms go off when the device overheats.
> Cloud update.
> The two-way wireless encrypted communication mechanism improves the security and stability of communication.
> With the wireless frequency hopping mechanism, the device automatically hops to other available frequency bands when the original frequency band is being interfered with by other wireless radios, to ensure communication remains smooth.
