Start with entry points, not a number
The most common question homeowners ask is “how many cameras do I need?” — but the better starting point is “where can someone get in, and where can’t I currently see?” Most break-ins happen at obvious access points: the front door, back door, ground-floor windows and, for many homes, an attached garage.
List every door and accessible window, then walk your property and note where you have no line of sight. That map — not a round number — tells you how many cameras you actually need.
A typical starting point for an average home
For a standard single-family home, a well-planned system often lands around four to six cameras: front entry, back entry, the driveway or garage, and one or two covering side approaches or the backyard. Larger homes, corner lots and properties with multiple access points naturally need more.
Quality and placement matter more than quantity. Two well-positioned cameras that cover approaches cleanly are worth more than five pointed at the same open lawn.
Cover the four priority zones
Front entry: captures visitors, deliveries and anyone approaching the main door — often paired with a video doorbell.
Rear and side doors: these are frequently out of view and are common entry points, so they deserve dedicated coverage.
Driveway and garage: protects vehicles and captures anyone approaching the property, often at a useful distance.
Backyard and blind spots: fills the gaps a would-be intruder would look for.
Don’t forget storage, lighting and the network
More cameras — and higher resolutions — mean more recording storage, so plan retention up front. Night performance matters too: choose cameras suited to low light for any area that isn’t well lit.
Finally, remember the network. Cameras rely on stable connectivity and, for wired systems, tidy cabling. A professional design accounts for all of this so the system is dependable, not just present.
