Seven things home CCTV actually does for you

13 September 2026 · iComm Solutions

Deterrence, evidence, remote checking and the insurance question — what cameras really change, and what they don't.

People ask for cameras after something has happened, which is the worst time to be choosing them. Here is what a home system actually changes, in the order it tends to matter, from someone who fits them.

1. It stops the opportunist, not the determined

Most domestic break-ins are opportunistic. A visible camera moves you down the list because the house next door is easier. That is a real benefit and it is worth having. What it is not is a force field: somebody who has decided on your house specifically will wear a hood and do it anyway. Cameras shift the odds; they do not remove the risk.

2. It gives you something to hand over

Without footage, a report is your word about a person you half-saw. With it, there is an actual description, a time, a direction of travel and often a vehicle. That is the difference between a crime number for the insurer and an investigation that goes anywhere.

This is also where resolution earns its money. A camera that proves somebody was there is easy. A camera that shows who, at 2am, from twelve metres, is a different specification — and the gap between the two is the main thing worth spending on.

3. You can look, from wherever you are

Modern systems stream to your phone, so "did I shut the garage" stops being a forty-minute round trip. On holiday it is the difference between a fortnight of low-level worry and ten seconds of checking.

4. It tells you whether the alarm means anything

An alarm going off tells you something moved. Cameras tell you what. If you are two hundred miles away and the alarm triggers, being able to see a cat rather than a person saves you calling a neighbour out at midnight — and on the occasion it is a person, you know immediately and you have it recorded.

5. It settles the arguments that are not crimes

The footage people actually end up using is rarely a burglary. It is the delivery marked as handed to a resident that was left in the rain, the reversing van and the gatepost, the boundary disagreement with a neighbour. Being able to look rather than argue is worth more day to day than the dramatic use everybody buys it for.

6. Your insurer may care — ask before you assume

Some insurers reduce a premium for monitored security. Many do not move at all for domestic CCTV, and a few want specific standards before they will count it. It is a five-minute phone call to your insurer and it is worth making that call before you budget on a discount that may not exist.

7. It costs a fraction of what it used to

The grainy black-and-white footage everybody pictures is two decades out of date. A sensible domestic system now records in enough detail to identify a face, keeps weeks rather than days, and costs less than a decent phone.

What to think about before you buy

Three things decide whether a system is useful or just present:

Where the cameras point. Covering the whole garden badly is worse than covering the two ways in properly.
Light. A camera is only as good as the worst conditions it has to work in, and that is 3am, not Sunday afternoon.
How long it keeps. People often discover something a week later. If the recorder holds four days, it has already gone.

One legal point worth knowing. Domestic CCTV that only covers your own property sits outside data protection law. The moment it captures a pavement, a shared drive or a neighbour's garden, the UK GDPR applies to you as the operator — which brings obligations about signage and about handing over footage when someone asks for their own. It is manageable and common, but it is better known about at the planning stage than discovered afterwards. The ICO publishes plain guidance on domestic cameras.

We install and supply systems across Northampton and Northamptonshire, and we will tell you when cameras are not the answer to the problem you are describing. A survey costs nothing.
