wireless alarms

Untethered security sensors

Wireless alarms are security systems that communicate between components—sensors, control panels, sirens—without physical wiring.

They use radio frequencies or Wi-Fi to transmit signals, making installation simpler and allowing placement where running wires would be impractical: The wireless alarms were up and running in an hour.

The term covers home security systems, car alarms, and commercial installations.
