An alarm that is designed around how you actually use the building — part-set for nights, full-set for empty days, and sensors that do not cry wolf every time a radiator ticks.
Book a free site surveyFrom our Hoddesdon base we cover Sawbridgeworth (CM21) for intruder alarms. Stony streets around the church, the station approach, and a short run to the M11 — homes, small workshops and the odd farm on the Essex border.
We design, supply, install and support intruder alarms for homes and businesses across Sawbridgeworth and the surrounding Hertfordshire towns. The survey is free; the proposal is fixed-price; the install is documented and handed over with remote access already working.
Homes that have outgrown a DIY siren, and commercial sites that need a graded system for insurance.
An engineer visits the Sawbridgeworth property, marks camera or device positions, and notes power, cable routes and any listed-building or landlord constraints. You get a written proposal within 48 hours. Certified engineers then install, label and test every device — typically in one or two days for a house, longer for a commercial site — and walk you through the app before they leave.
Hoddesdon is our home patch, so Sawbridgeworth (CM21) is a normal travel job, not a long-distance add-on. Nationwide commercial work is still available when a group has other sites further out.
We install to the grade your policy asks for. If they specify PD 6662 / EN 50131, that is what goes on the proposal — not a consumer kit with a sticker.
Yes. Alarm activations can throw the nearest cameras to live view and bookmark the NVR so you are not scrubbing an hour of footage.
Pet-tolerant PIRs exist, but they are a compromise. For dog-heavy homes we often use contacts and carefully aimed cameras instead of hoping the PIR “ignores” a labrador.
