For a normal single-family home, 2–4 well-placed cameras are usually enough. The goal isn’t to cover every inch of the property like a bank; it’s to watch key access points and give you a clear idea of who came and went.
A common setup looks like this:
- One camera facing the main entrance / front door.
- One covering the driveway or front yard.
- One watching the back door or backyard.
- Optional extra one for a side entrance or a dark spot that’s hidden from the street.
Placement matters more than quantity. A single camera at the front, mounted at the right height with a clear view of faces, is more useful than three pointing at useless angles. Also, think about lighting at night – cameras near a small light or motion sensor lamp give much clearer footage.
In apartments, sometimes one camera at the entrance door or overlooking the corridor outside is enough, depending on building rules and privacy limitations.
