Improve your home's security with a range of intruder alarms from Dereham Security Alarms. We install alarm systems that send a coded message to our receiving centre, who will contact your keyholder or the police. If you opt for a bells-only system, the alarm will sound only on your premises but are loud enough to alert neighbours. Contact us for details. We serve clients across the Dereham area including all small, remote villages and bigger towns like Swaffham and Fakenham.
