I recently had a CCTV system installed by Wilson Alarms. They offered professional advice on the type of system/cameras and at a competitive price. They were prompt, honest, polite and the technician was highly knowledgeable.
Wilson Alarms Systems Ltd give an excellent service and represent great value for money. All of their engineers / staff are very knowledgeable – I chose them about 10 years ago for a commercial contract and I am more than happy with them still.
