DHI Keyfob ARA24

The ARA24-W2(868) is a wireless remote control from Dahua for easy operation of alarm systems built around Dahua's wireless hubs. With four buttons – Home, Away, Disarm, and SOS – the user can quickly switch alarm modes or trigger a panic/emergency alarm directly from the fob.

The remote control also supports control of roller shutters and doors, as well as both local and remote operation. Thanks to two-way communication and frequency hopping, the fob communicates stably and interference-free with the hub at a distance of up to 900 meters in open areas, with support for jamming detection and encrypted communication for added security.

The unit is powered by a CR2032 battery with up to 3 years of battery life and features real-time power consumption monitoring and support for connecting high-power devices. The fob supports cloud-based remote updates (OTA) with automatic rollback if an update fails, as well as several installation methods for flexible mounting.
