Wireless alarm installation in Kent
Ajax alarms that arm from your phone, tell you which sensor triggered and which door opened, and integrate with your cameras. No drilling channels into the walls, no dated keypad by the front door.


The alarm that texts you before it wakes the neighbours
Ajax is the system we are authorised to install because it is the one we would choose ourselves. Wireless sensors with five year batteries, a hub that talks over broadband and 4G so it keeps working if the internet drops, and an app that shows you exactly what happened and when.
- Ajax authorised installer, Grade 2 equipment suitable for insurance
- Motion, door, glass break, smoke, leak and CO sensors on one system
- Arm and disarm from your phone, a key fob or a keypad, with schedules and geofencing
- Alerts with photo verification from motion sensors with built in cameras
- Integration with CCTV, smart locks and lighting so a trigger turns the lights on and shows you the camera
What an Ajax system can do
Beyond the burglar alarm. One hub can look after security, fire, water and the people inside.
Intruder detection
Motion sensors that ignore pets, door and window contacts, glass break detectors and outdoor sensors for the garden.
Photo verification
MotionCam sensors take a series of photos when triggered so you can see whether it was the cat or a burglar before you call anyone.
Fire, smoke and leaks
Smoke, heat, CO and water leak sensors on the same app. A leak under the sink can be caught in minutes rather than weeks.
Access and keypads
Keypads, key fobs and app control with individual codes for family, cleaners and dog walkers, with a log of who armed what.
Business alarms
Shops, offices, units and farms with zoning, opening and closing schedules and multiple users.
Smart integration
Lights on and cameras up when a sensor triggers. Sirens indoors and out. Everything from one app.
How an alarm install works
Free survey
Aaron walks the property and identifies the entry points, the rooms that matter and where sensors should sit.
System design
A written plan listing every sensor, siren and keypad, with the price. Usually with you the same day.

Wireless sensors fitted, the hub connected and configured, sirens mounted. Most homes are done in half a day.
Handover
App set up for everyone who needs it, arming schedules configured and a full test with you watching.
Alarm plus cameras is where it gets useful
On its own an alarm tells you something happened. With cameras on the same system you can see what it was, in colour, from your phone, and decide what to do. We install both, and we make them talk to each other.

Alarm systems questions
Is a wireless alarm as good as a wired one?
For modern systems, yes. Ajax is Grade 2 certified, uses encrypted radio with jamming detection and reports over broadband with 4G backup. It is accepted by insurers and avoids the disruption of chasing cables into your walls.
Do you offer monitoring?
Yes. Self monitoring through the app is included, and for homes and businesses that want it we can connect the system to a monitoring centre that will call keyholders or the police. Aaron will explain the options and costs during the survey.
How long do the batteries last?
Ajax sensors run for around five years on their batteries and the app tells you well in advance when one needs changing. On a care plan we replace them as part of your annual check.
Can I have pets in the house with the alarm set?
Yes. Ajax motion sensors have pet immunity for animals up to around 20kg. For larger dogs we position sensors and use door contacts so you can arm the house without false alarms.
What does an alarm cost in Kent?
A typical Ajax home system with a hub, four sensors, a keypad and an outdoor siren, installed and set up, is from around £750. Adding smoke, leak and camera sensors is itemised on the quote so you can build the system you want.
