Security exhibition

South Africa's anti-crime and security businesses displayed their latest wares at the recent 3-day Securex exhibition in Johannesburg. Many products display the Proudly South African label. The displays featured, amongst others, electrified razor wire, flak jackets, and a lock that emits a sound like a gunshot blast if the wrong person tampers with it.

Pierre Halle invented Robo Guard after two friends were killed in farm attacks. A portable canister with an infrared sensor, it can detect an intruder at up to 20m and set the alarms ringing. Profilon is a security lamination for car windows that promises to resist bricks, rocks or even bullets. Cellsecure has designed gadgets such as one that lets you turn your lights on and off at home via your cell phone while you are away. One company has razor wire which is electrified as well as sharp steel spikes for lining the top of the garden wall. The Shock Padlock reacts to vibrations with a starter-gun blank cartridge making an explosive echo in its aluminium shell.
