Services
*Domestic and Commercial Security Solutions*
M25 Security Systems Ltd can provide security solutions for both domestic and commercial premises. Whether you are looking for a new system, upgrading your existing system, or just want your security equipment serviced regularly under a maintenance agreement by an SSAIB registered Security Company, we can help. We can install your Alarm, CCTV, and Entry system with minimal disruption. If it is a new build, we will install your wiring before plastering/decoration so all cables are concealed.
*Intruder Alarm System*
There are two main types of burglar alarm: Bells only and Monitored Systems. Bells only systems rely on sounders to both deter the burglar and also warn neighbours of the intrusion. Monitored Systems have all the features of the 'bells only' system with the addition of being monitored by an Alarm Receiving Centre via a telephone line and/or radio link. When the alarm is triggered, it sends a signal to the Alarm Receiving Centre, who then notifies the key holders and police of the alarm.
*Entry Systems*
We offer audible or video entry systems with entry via a keypad or proximity reader with tags or cards. There are several different options and choices dependant on your needs.
*CCTV*
Whether you require one camera or ten, budget or top of the range, these can be installed in both domestic and commercial premises.
