Smart Alarm Systems in St Albans

St Albans is a city of period homes, conservation areas around the Cathedral and Verulamium Park, and a strong professional residential base across Marshalswick, Jersey Farm, Sandridge and out toward Harpenden. A lot of these properties are exactly the kind of homes where a wired alarm system is awkward to retrofit. Cables and chasing into solid Victorian walls, holes in plaster, the panel hidden in a cupboard you forget exists. The result is often a system that goes unused.

Ajax was designed for this. Every Ajax device is genuinely wireless, with a sealed lithium battery in each component that lasts up to seven years. The hub talks to every sensor over Ajax’s own encrypted radio. There are no cables to chase, no plaster repairs, no compromises on which rooms you can protect. The whole system installs cleanly in a single day on a typical St Albans home.

We have been the family run installer doing this work for St Albans clients since 2014. The Ajax wireless install we documented at a St Albans property is on our blog if you want to see what one of these jobs actually looks like in practice (read the St Albans Ajax case study).

The components below are the ones we fit most often on St Albans installs. Every job is designed around the property during the free site survey, but this gives you a sense of what a typical system includes.

• Ajax Hub 2 Plus. The brain of the system. Connects to the internet over Wi Fi, ethernet or two SIM cards (so it stays online even if your broadband drops), and talks to every Ajax device over Ajax’s own encrypted radio. Backup battery keeps the system live during a power cut.
• MotionProtect and MotionCam sensors. Pet immune passive infrared sensors covering a 12 metre cone, ideal for hallways, landings and reception rooms. MotionCam adds a small camera that takes a short photo series when the sensor triggers and sends them to the app inside ten seconds.
• DoorProtect and GlassProtect. Door and window contacts that report any opening within a second, plus glass break detection that listens for the specific frequency of breaking glass.
• FireProtect 2. Smoke and carbon monoxide detection in one device, feeding into the same alarm and the same app.
• KeyPad and SpaceControl. Wall mounted keypad at the front door for code based control, plus pocket key fob for arming or panic activation from the car or by the bedside.
• HomeSiren and StreetSiren. Internal sounder and external sounder with flashing strobe, both battery powered and tamper protected.

We install Ajax across St Albans and the surrounding areas every week, with regular jobs in:

St Albans: the Cathedral conservation area, Marshalswick, Jersey Farm, Sandridge, Bricket Wood, Park Street, Chiswell Green, Verulam.

Wider Hertfordshire: Harpenden, Wheathampstead, London Colney, Redbourn and the surrounding villages across the AL postcodes.

If you also need CCTV alongside the alarm system, see our dedicated St Albans CCTV installation page. We design and install combined CCTV and Ajax systems every week, so the two integrate cleanly when fitted together.

If your address is outside the named areas, get in touch with the postcode and we will confirm whether we can cover it. Coverage extends past the named clusters and into the surrounding villages.
