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 Stevenage (SG1) for intruder alarms. New-town neighbourhoods, the leisure and retail core, and a serious industrial/warehouse belt that wants yard and loading-bay coverage.
We design, supply, install and support intruder alarms for homes and businesses across Stevenage 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 Stevenage 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 Stevenage (SG1) 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.
