Every 26 seconds, a theft happens in the UK. ThiefStop is the alarm built to make sure it’s not your van, shed, or e-bike that’s hit.

With a 120 dB siren as loud as a jet engine, it delivers an instant, heart-stopping deterrent to any intruder. The 6–8m PIR motion sensor reacts the moment movement is detected.

Power comes from 4× AAA batteries with up to 6 months life — most likely the longest lasting in its class. No wiring, no hassle, just install and protect.

Unlike cheap alarms, ThiefStop is rugged and anti-tamper. Its unique bracket system fixes in place with an Allen key (included), making it tough to pull off or disable. And with the included remote fob, you can arm and disarm in seconds — fast, simple, convenient.

Designed in Britain, UK patented, CE + UKCA certified, and built to protect what matters most.
