Your Best Defence Against Burglary & Intruders

The latest crime statistics for Kent show that, after two years of falling burglary rates, they are now on the rise again and are the highest they’ve been for two years. A good intruder alarm system is your best defence against the nightmare of being burgled.

An intruder alarm isn’t just there to catch thieves in the act, it serves as a very effective deterrent. Research shows that intruders prefer to go for soft targets, i.e. businesses that are not fitted with intruder alarms.

I have to say we received exceptional service yesterday. Clive the engineer was on site within 30 minutes of me making the call and he was extremely efficient sorting out and replacing the unit.

Wired or wireless?

We install wired and wireless alarm systems, with the majority of business customers requiring wired systems. Wireless systems are quicker and easier to install but they don’t scale to meet the requirements of larger premises.

Call us at your site planning stage and we will be able to install a wired intruder alarm with the minimum of disruption.

At the end of the day, each site is different. That’s why we offer a free site survey from one of our experienced surveyors to put together the best solution for your business needs and budget.
