Products & Services



Our CCTV Systems can monitor your home and business premises 24/7. Up to 16 cameras can be used to cover your property. The cameras give a Full HD 1080p picture and glow red at night which is a great deterrent. You can also use a USB memory stick to copy recordings which can be used as evidence in a court of law etc.

Wireless Alarms

Wireless Alarms

No mess to decorations or carpets. A very reliable and easy to use system to deter today's would-be thieves.
The control panel is the only item that is wired to the electrical mains of your premises.
It has a standby rechargeable battery in case of any power cuts. It also has a built-in Telephone Dialler which can be fitted to your existing phone land line to deliver a message to your mobile etc. (up to four phone numbers) in the case of an alarm.
If you receive a message you can (a) listen in (b) talk back i. e. "the Police are on their way".
You can also arm or disarm your alarm system from a phone!
Another feature is the "Latchkey" facility - when a child arrives home from school etc. a message will be sent to your phone to let you know they have arrived home safely.

Customer Testimonials

Twenty three years of excellent service. Thank you Masterguard Security.

We “inherited” the burglar alarm (and Colin) when we moved into the house. Colin has kept the system running efficiently which we were very thankful for when someone attempted to get into the house one night. The alarm went off and no one came in – worth its weight in gold.
