Cooling criminal cravings

July 2018 Security Services & Risk Management, Products

The high crime levels in all areas of South African life has not shown any signs of abating, in fact, the numbers have increased over the past few years. We only need to look at farm murders and cash-in-transit attacks to realise that things are not improving.

When it comes to the protection of a home or business, there are options to choose from for added security, but not all of these are effective. Home and small business owners in particular are not offered security measures tailored to their requirements (unless they have an enormous amount of money to spend), but are offered generic one-size-fits-all solutions.

Günther Wockelmann from Roteck South Africa believes that the result of this status quo is simply a reactive security operation that reacts after the criminals have done what they intended. As Wockelmann says, “Since a bullet only needs 20 milliseconds to reach a target, I believe that, especially in crime, every second counts.”

This means that blurry images from late-night CCTV operations and having a tracker in your car that allows someone to find your vehicle (hopefully) after it has been hijacked are simply not good enough. We need to be able to identify and deter criminals before they are in control of the situation. In other words, pressing a panic button once they are in your house is too late.

Wockelmann has therefore come up with a solution that could deter criminals, but at the very least will delay them for long enough to allow potential victims to secure themselves. The solution is water.

Wet and unhappy criminals

During his research, Wockelmann found that crime statistics were much lower when it was raining. Not even criminals want to work in the pouring rain. Roteck has therefore designed a few security products that douse criminals with water when they try their luck. This works especially well when the water is sprayed from an inconvenient angle, like from the ground up.

The solution is not simply a water cannon of some form, but early detection and a generic spray nozzle or sprinkler. Catching the fiends before they are in control is important, after which you can apply your water protection to delay them. And even if they are determined to continue, you have given yourself more time to secure yourself and your loved ones, and call for help.

Wockelmann adds that there are also different ways to enhance the efficiency or your water protection without causing permanent damage to the target. For example, mixing the water with harmless liquid bio fertiliser (which leaves an unpleasant smell for days), dishwasher liquid (which creates foam and a slippery surface) or food colouring (which sticks to the target for a long time) can make their crime spree very unpleasant.

He says even cold drinks containing sugar are an option as they leave a sticky and inconvenient mess. Then you can also add other unpleasant products, such as pepper or chili (with oil to prevent clotting), or even a drop of Tabasco.

Easy to install and use

The Roteck systems can be triggered manually by an individual (there’s even a solution that attaches to a car to discourage hijackers and window washers – see image), or automatically by existing security sensors. Many surveillance cameras include analytics that trigger an event when someone walks into a specific area, if this area is in front of your door, for example, you could ensure unexpected snoopers receive a cold welcome.

Roteck has developed a number of liquid security solutions which can be used indoors and outdoors. These are not the water cannons one sees the police using against rioters on TV, but they dispense enough water to make anyone on the receiving side unhappy. The solutions are power friendly and can even run on battery power during power outages.

The company’s latest product is the eGuard, an automated revolving 4-channel high-pressure water spray system for indoor and outdoor applications. The outdoor version operates with high pressure tap water, while the indoor version is portable, battery operated and fuelled from a canister. This canister can store any none corrosive liquid or mixture hereof. A similar but smaller system is available for vehicles to be activated in case of hijacking attempts.
