The short answer
Most homes need about four to eight cameras. Cover the entrances, the driveway or gate and the blind side of the property rather than counting rooms. Plan around where someone would approach or climb in, then add cameras for the vulnerable spots.
| Type | Good for | Watch out for |
|---|---|---|
| Bullet | Long views, such as a driveway or a wall | Visible and easy to angle, but easier to reach |
| Dome | Doors and covered areas | Harder to tamper with |
| Turret | Night-time clarity and simple set-up | Check the field of view for your spot |
There are two jobs a camera can do: show what is going on, and help identify a person or a number plate. For a general view, a standard resolution camera is often enough. For a gate or a door where you want a face or a plate, choose a higher resolution and place the camera at the right distance and angle. Ask your installer to test the view before fixing it.
Cameras only help if they are running. Plan for load shedding from the start. Read CCTV and load shedding, and make sure you can view them remotely: viewing CCTV on your phone.
Make sure your camera positions respect your neighbours and your estate’s rules. See is CCTV legal at home in South Africa?
This is an illustration, not a fixed plan.
| Position | Cameras | Purpose |
|---|---|---|
| Front gate and driveway | 1 | Vehicles and faces as people arrive |
| Front door | 1 | Visitors at the door |
| Garage and side access | 1 | A common entry point |
| Back door or patio | 1 | Sliding doors and the rear entrance |
| Back garden and wall | 1 | The blind side of the property |
| Side passage | 1 | A narrow route that is hard to see from the street |
| Total | 6 |
Many people only use outdoor cameras. Indoor cameras raise privacy questions, so think carefully about where they go.
Not always. It uses more storage and bandwidth, so match it to the job.
Often one or two covering the front door and balcony, subject to your building’s rules.
They may deter some people, but they give no footage when you need it.
It depends on the number of cameras, the resolution and how many days you want to keep. Ask your installer to calculate it.
