Description
The Dahua ARD821-W2(868) is a miniature wireless panic button with a single key, 55×36×14.2 mm in size, that talks to the hub in the 868 MHz band over a two-way encrypted (AES128) link from up to 1,200 m in open space. It is guarded against accidental presses, a multi-colour LED shows status, and the app displays battery level and signal strength. It runs on a CR2032 cell that lasts 3 years when used twice a week; IP54 rating, –10 to +55 °C operating range. Works as a key fob for a home alarm owner, a cashier in a shop or an elderly person calling for help.
