Latest updates - IP Network
By 2025, as a result of BT replacing old phone lines, monitored alarm systems transmitting to an Alarm Receiving Centre will require updating across to the IP network. We have started this transfer for our customers. For further information on how this might affect your system, give us a call.

Whether you’re looking to boost security in your home, office, shop, warehouse or academy, we offer a comprehensive range of intruder alarms. These systems are designed to deter opportunist intruders, whilst our collection includes bells-only alarms, auto diallers, smart home alarms, dual path signaling systems and monitoring contracts.

CCTV
The UK has more CCTV activity than any other country, with many homes and businesses kitted out with cutting-edge cameras. From providing peace of mind to collecting crucial evidence, CCTV systems are continuously playing an important role in society. MJ Security are recognised as the leading CCTV installers in Bedfordshire, so whether you require 24-hour protection with infrared lighting, remote CCTV and protection services or a simple domestic system with a small flat-screen monitor, we can provide the perfect solution for your environment.

It’s true that most criminals seek out opportunities with few risks and high rewards, but access control is designed to deter intruders, increase safety, reduce theft, secure sensitive information and ensure you have no undetected strangers within your building. We’ve installed door systems and access control solutions for a comprehensive range of domestic and commercial customers, from individual dwellings to hundreds of communal doorways in business parks.

We also provide 24/7 monitoring via our alarm-receiving centre (ARC), whilst our fully trained team is equipped to deal with complex situations quickly and efficiently. Our emergency security systems and monitoring services are designed to ensure you remain in complete control, guaranteeing prompt action is taken in the event of a genuine alarm, such as contacting emergency services. We offer flexible maintenance packages, taking your needs and budget into account, whilst our highly qualified engineers can provide regular maintenance to ensure your equipment is working properly at all times.
