Gavin was very informative as helpful in the selection of alarm that was right for my home. The app was an added bonus so now I can set from my alarm. I would not hesitate in using him again More...

We are a high value car dealership and thanks to Threshold Security Systems we were able to get a conviction on someone who broke onto our site via the CCTV system they installed for us. We would highly recommend this company to anyone who is looking for a security system. More...

We can provide both hardwired and wireless home security systems for complete peace of mind. We also offer a range of pet friendly alarm systems so you can protect your property whilst allowing your pets to wander as usual. We can also provide systems with auto dialler options via a landline or GSM mobile network alerting you or an ARC (Alarm Receiving Centre) should your system go into alert. Our engineers will advise whether a wired or wireless solution is appropriate for you. You may worry that having a burglar alarm installed will cause disruption to your home. Our installation team are trained to conceal all wires when installing the system, making the install as invisible as possible! All our engineers genuinely respect the fact that we will be working in your personal property and take care to carry out the installation with the minimum disruption. We will always clear up before we leave! Our system designers will work with you to create a unique system, designed to match your individual requirements and budget, whatever the size or the complexity.

Going away? Last minute holiday or working away from home? Who will be looking after your property whilst you are away? We can supply a professionally fitted alarm at a small monthly rent with a visible bell box at short notice. Between tenants? Property unoccupied for long periods can attract squatters, vandals and other criminals. This often leads to damage and can be a costly headache. To deter potential unwanted tenants we can fit a temporary alarm which will not only offer you peace of mind, but often reduce your insurance premiums.

Maintenance Plans A maintenance contract is a prudent way of protecting your investment in your system – ensuring your equipment is kept in good working order so it won’t let you down when you need it. We not only offer maintenance plans for systems we install, but can offer a similar service for those installed by other companies. * Peace of mind and priority service - We ensure that your alarm stays fully operational and attend to any problems without delay. * Regular servicing - As you would expect, we carry out regular and full inspections. Audible only alarms are carried out once a year, whilst signalled alarms and more complex systems are serviced twice a year. * Continued police response - It is important to note that if your signalled alarm is not maintained, you run the risk of losing police response. * Lower insurance - Is maintenance a condition of your insurance policy? Many insurers offer a discount if a property is protected by a regularly maintained intruder alarm. System Support Have you just moved into a house with an alarm and no code? Or a CCTV System you can't operate? Don’t panic, our engineers are trained on a wide range of panels and equipment which means it is likely that we will be able to get the system up and running without replacing it!* * This is subject to the system being operational after full testing and not being locked by the original installer.
