How Many Cameras Do You Actually Need for a Average Home?
We are in the process of setting up security cameras for the first time and I am genuinely confused about how many cameras we actually need. Every article I read gives a different answer and every company I speak to naturally recommends more cameras than the last one.
Our property is a standard suburban home, single story, three bedrooms, attached garage, medium sized backyard with a side gate on each side. Nothing unusual about the layout but I keep getting quotes ranging from four cameras all the way up to ten and I have no idea how to evaluate whether that range makes any sense for our situation.
The salesperson at one company told us we needed eight cameras minimum for proper coverage. Another installer came out and said four well placed cameras would cover everything we actually needed. The difference in price between those two quotes was significant and I genuinely cannot tell if the higher quote is better or if we are just being upsold.
I understand that every property is different and placement matters as much as quantity but is there a general rule of thumb that people use? Like front door, back door, garage, and one wide angle for the backyard seems logical to me but I do not want to find out after the fact that we had an obvious blind spot that could have been easily covered.
What did you end up going with for a similar sized home and do you feel like you have the right number of cameras or do you wish you had added more?

For a property like yours, the four camera approach is almost always sufficient if the placement is done correctly. The eight camera quote sounds like upselling. Front door, back door, garage entrance, and one covering the side gate or backyard is a solid baseline for a standard single story suburban home.
The key thing most people miss is lens angle and camera height. A wide angle camera placed too high loses all facial detail. The goal is coverage that actually captures usable footage, not just movement, so placement matters far more than quantity.
Where the higher camera count makes sense is when you have multiple entry points, long driveways, detached structures, or large open areas where a single camera cannot cover the full zone without leaving blind spots. For your layout that does not sound like the case.
My honest advice is to get your layout assessed by security camera experts who will tell you what you actually need rather than what generates the highest invoice.
