What we install in Northwood
One installer for the whole house
On a large Northwood property the system has to cover the whole plot, not just the front door: the gate, the drive, the garage and the far end of the garden. We design alarm, cameras and intercom together so they work as one, on one app.
CCTV cameras
4K cameras with full-colour night recording, person and vehicle detection, and 30+ days of footage kept at home — no subscription.
CCTV installation →Gate & door intercoms
IP video door entry at the gate or front door. See and talk to visitors from a screen indoors or your phone, wherever you are.
Ask about intercoms →Alarm upgrades & takeovers
Old panel, lost engineer code, or a system the previous owner left behind? We keep the sound wiring and sensors and replace the brains.

How we approach Northwood homes
Northwood is one of the greenest corners of North West London, and many of its houses sit on big plots with mature trees, long drives and woodland at the back. More ground and more cover means more places to approach unseen — so where the cameras and detectors go matters more than how many there are.
Northwood, Moor Park, the Eastbury side
Gated drives, double garages, pool houses and gardens backing onto woods and golf courses.
- Cameras placed to identify faces and number plates at the gate, not just show the drive.
- Detectors in garages, gyms and garden rooms on the same system, with a range extender or an external-grade duct run.
- External detection along the approach so you know someone is there before they reach the house.
Northwood Hills and around
Semis and detached houses with side access, a long garden and often a rear extension or loft conversion.
- Door contacts on every external door, motion detectors in the ground-floor rooms.
- First-floor rooms reachable from an extension roof covered as well.
- Four cameras usually does it: two at the front, one at the side, one over the garden.
Know who is at the gate
A video intercom at the gate lets you see and speak to visitors from inside the house or from your phone when you are away. It sits on the same network as the cameras, so the gate camera and the intercom tell one story.
Alerts you can trust from anywhere
If you travel, the system should tell you what matters and nothing else. We set person and vehicle detection so you get an alert for someone on the drive at 2am, not for every fox or swaying branch, and the alarm reports straight to your phone wherever you are.
Northwood sits in the London Borough of Hillingdon, while Moor Park and Batchworth Heath are just over the county line in Hertfordshire. Parts of the area are conservation areas — we keep external equipment discreet and will tell you at the survey if anything is worth checking with the council first.

New alarm systems are priced after the survey because the device count depends on your doors, windows and layout. Anything that adds cost — a long run to the gate or an outbuilding, scaffolding, cable through finished walls — is flagged at the survey, never on the day.

FAQs
Security in Northwood: your questions answered
How much does a burglar alarm cost in Northwood?
It depends on the house. Replacing an old panel and keeping your existing wired sensors starts from £495 + VAT. A new system is priced from a free survey, because a Northwood Hills semi needs far fewer devices than a detached house with a gated drive and outbuildings. You get a fixed written quote before any work is booked.
How much does CCTV cost in Northwood?
Guide prices, installed and including VAT: two cameras from £695, four cameras from £1,095 and eight cameras from £1,895. Larger Northwood plots with a long drive, gates and outbuildings usually sit in the eight-camera range. Anything that adds cost, such as a long run to the gate, is flagged at the survey.
Can you fit a video intercom at the gate?
Yes. For houses with gates or a long drive we fit IP video door entry, so you can see and speak to visitors at the gate from a screen indoors or from your phone, wherever you are.
Will cameras keep alerting me about foxes and trees?
Not if they are set up properly. We use cameras with person and vehicle detection and draw the detection zones at handover, so wildlife and moving branches in a leafy garden don't flood your phone with alerts.
Can you fit an alarm without damaging decoration?
Yes. In a finished, occupied home we normally install a wireless system such as Ajax, so there is no chasing and no redecorating. Wired systems are best when you are renovating and the walls are open, installed as separate first and second fix visits.
Can you take over my existing alarm?
Usually, yes, including systems we did not install. Where the existing wiring and detectors prove sound we keep them and replace the panel and keypad, which is far cheaper than a new system.
Which parts of Northwood do you cover?
All of HA6: Northwood, Northwood Hills, Haste Hill, Eastbury, Moor Park and Batchworth Heath, plus neighbouring Ruislip, Pinner and Eastcote. We are based in Harrow, around twenty minutes away.
What guarantee do I get?
A 12-month guarantee on our installation work, alongside the manufacturer's warranty on the equipment we supply.
