How many CCTV cameras does a house need?

The direct answer

There is no standard camera count for every home. A small property with one clear entrance may need fewer views than a detached house with a drive, side access, rear garden, garage and outbuildings.

The survey should decide what each camera must show and whether the customer needs live alerts, continuous recording, detailed vehicle views or general awareness.

Common residential views

Many designs start with the front approach and then address routes that are not visible from the street.

• Front door and approach
• Driveway and parked vehicles
• Side gate or alley
• Rear doors and patio
• Garden and boundary approaches
• Garage doors
• Detached outbuildings
• Long or gated driveways

One camera cannot always do two jobs

A wide camera may show the whole drive but provide less detail at the gate. A close entrance view may capture faces but not the vehicle area. Position, lens, distance and lighting should match the purpose.

Mounting cameras too high can create impressive overviews while losing useful facial detail. Appearance matters, but the view must still work.

Recorder-based versus smart cameras

A professional recorder-based system can provide consistent multi-camera recording and playback. Smart cameras, doorbells and floodlight products can suit customers prioritising app convenience, alerts and a lower-disruption installation.

NOX explains the difference without describing smart security as a budget substitute.

Privacy and future maintenance

Camera views should focus on the property requirement and avoid unnecessary coverage of neighbouring areas. The customer should also be able to access playback, manage users and maintain clean, useful camera views after installation.
