Home CCTV Buying Guide: What to Know Before You Install

CCTV has become one of the most popular ways to protect a home. Whether you are after a single doorbell camera or a full system covering the driveway, garden and outbuildings, a little planning before you buy makes a big difference to how useful the cameras turn out to be, and to how they sit with your neighbours.

This home CCTV buying guide walks through the main things to think about, in plain English, so you can choose a system that does the job without over-spending or causing problems down the line.

Start With Why You Need Cameras

Before looking at kit, it helps to be clear about the problem you are trying to solve. Government guidance on domestic CCTV suggests asking whether cameras are really the answer, or whether something simpler, such as better lighting, would help. It also suggests thinking about what exactly the system needs to see and whether it needs to record all the time.

Common reasons homeowners give include:

• Keeping an eye on cars parked on the driveway

• Seeing who is at the front door, especially when away from home

• Protecting sheds, garages and garden outbuildings

• Deterring opportunist thieves and providing evidence if something does happen

Writing down your reasons first makes every later decision easier, from how many cameras you need to where they should go.

Choosing the Right Cameras

There is no single “best” camera. The right choice depends on what each one needs to see and how far away it is. A few points worth weighing up:

• Field of view: a wide view suits a garden or driveway, while a narrower view gives more detail at a specific point such as a gate or door.

• Image quality: higher resolution helps with detail, but positioning and lighting matter just as much. A well-placed camera usually beats a high-spec one in the wrong spot.

• Night-time performance: outdoor cameras often need to work after dark, so check how each camera performs in low light.

• Build quality: outdoor cameras need to cope with rain, wind and cold winters.

Doorbell cameras are a popular starting point, but they generally only cover the area right in front of the door. Many homes benefit from combining one with a small number of fixed cameras.

Wired, Wireless and Where Footage Is Stored

Systems broadly fall into two camps. Wired systems connect cameras back to a recorder inside the property, which tends to give a stable connection and avoids batteries that need recharging. Wireless and battery cameras are quicker to fit, but depend on a good Wi-Fi signal and regular charging.

You will also need to decide where recordings are kept:

• On a recorder at home, which keeps footage on your premises.

• In the cloud, often through a subscription, which means footage is still available if a device at home is stolen or damaged.

• A mix of both, which some systems support.

Whichever you choose, government guidance recommends checking the date and time on the system are correct and that there is enough recording capacity. If footage is ever needed by the police, accurate timestamps matter.

Smart Features and Keeping Your System Secure

Most modern cameras let you view live footage and receive alerts on your phone. That convenience comes with a responsibility to keep the system secure.

Since 29 April 2024, UK law under the Product Security and Telecommunications Infrastructure (PSTI) regime has required manufacturers of consumer smart devices to:

• Stop supplying devices with easily guessed default passwords

• Provide a way for people to report security problems

• Say how long the product will receive security updates

When comparing cameras, it is worth checking how long the manufacturer promises updates for. The National Cyber Security Centre also advises changing any default password on a device or its app to a strong one, turning on two-step verification where available, and installing updates promptly.

Positioning Cameras and Respecting Your Neighbours

Where cameras point is just as important as which cameras you buy. The Information Commissioner’s Office (ICO) explains that if fixed cameras, including smart doorbells, capture images or audio beyond your property boundary, data protection rules apply to you. Recording outside your boundary is not in itself unlawful, but it does bring some responsibilities.

According to ICO and government guidance, if your cameras capture areas beyond your property you should:

• Let people know recording is taking place, for example with a sign

• Delete footage regularly, or set it to delete automatically

• In most cases, provide relevant footage if someone you have recorded asks for it, and delete recordings of a person if they ask

• Keep recordings secure and limit who can see them

• Use footage only to protect your property, not for sharing on social media

Audio is covered by the same rules as images, so think carefully about whether you need sound recording at all. The ICO also recommends pointing cameras away from neighbours’ homes and gardens, shared spaces and public streets where possible, and using privacy masking or repositioning where it isn’t. Having a quick chat with neighbours before installing can avoid misunderstandings.

DIY or Professional Installation?

Plug-and-play cameras can work well for simple jobs. A professional installer can help with planning coverage, cable routes, camera angles that avoid neighbouring properties, and setting up remote viewing and security settings correctly. For larger homes or properties with outbuildings, a site survey often saves money by showing exactly how many cameras are really needed.

A Quick Home CCTV Checklist

• Know what you want each camera to see, and why

• Choose cameras suited to the distance, lighting and weather

• Decide between local recording, cloud storage or both

• Check the security update period and change any default passwords

• Position cameras to minimise views of neighbours and public areas

• Put up a sign and set sensible automatic deletion
