The Pain: You press your gate remote, the motor beeps, and you drive away to work. But what if the gate never actually closed behind you?
The Agitation: Criminals are increasingly using remote jammers to gain silent, unforced entry into properties across the Western Cape. If your gate is left wide open, your home, family, and vehicles are completely exposed to intruders.
The Promise: In this article, we explain exactly how criminals block your gate's signal and how to fix this vulnerability immediately.
The Short Answer: Criminals use illegal handheld devices to flood the 433MHz radio frequency, blocking your remote’s signal so your gate won't close. To prevent this, you must physically watch the gate close, upgrade to a smart gate motor with push notifications, or install a dedicated signal jamming detector.
How Gate Remote Jamming Actually Works
Criminals often wait in unmarked vehicles near your driveway. They carry a simple electronic jamming device that broadcasts a powerful, continuous radio signal. Most standard remotes operate on the open 433MHz frequency band.
When you press your remote to close the gate, their jamming device drowns out your remote's signal. It acts exactly like a blasting siren covering up a whisper. Your gate motor simply does not receive the command to close.
