Quick answer
Most homes need one camera for each entry point you want to watch, such as the front gate, the front door, the back door and the driveway, plus any blind side or perimeter wall that someone could climb unseen. Count your entry points and approach routes first, then decide how many cameras cover them clearly.
The right number depends on the layout of the property, not the size of the house. A camera that captures faces at the gate is worth more than several wide shots that show only shapes.
Step-by-step guidance
- Walk around the property and mark every gate, door, window and wall where someone could get in.
- Decide what each camera must do: identify a face or number plate, or give a general view of a yard.
- Place cameras so they cover each other where possible, making it harder to disable one unseen.
- Ask an installer to assess night lighting, since infrared and low-light performance differ between cameras.
- Confirm how long footage is stored on the recorder or cloud service and how you will view it remotely.
What to check
- Camera resolution and night-vision capability for each position
- Recorder storage capacity and how many days of footage it keeps
- Backup power so cameras keep recording during load-shedding
- The installer's registration with PSIRA, which you can confirm on its website
Common mistakes to avoid
- Pointing cameras into bright light or directly at the sun
- Mounting cameras so low they can be reached and tampered with
- Recording neighbours' property or the street more than you need to
- Never testing playback until after an incident

Frequently asked questions
How many CCTV cameras does a typical house need?
It depends on the number of entry points and blind spots. Start with one per gate or door, then add cameras for walls or yards that cannot be seen.
Do CCTV cameras work during load-shedding?
Only if the cameras, recorder and router have backup power, such as a UPS or inverter. Ask the installer to plan for this.
Can I record the street or my neighbour's yard?
Recording personal information is governed by POPIA. Keep cameras focused on your own property and check guidance from the Information Regulator.
