How many cameras does a property need?
Short answer: Count the places you need to see, not the walls of the building. Most properties need one camera for each entry point, one for each driveway or gate, and one for each outbuilding or yard area that matters to you. A typical home lands in the 4 to 8 range, while farms and larger properties often need more.

Start with how people arrive
List every way a person or vehicle reaches the property: the end of the driveway, the gate, the front and back doors, the garage and any walk-in doors on barns or shops. Each of those spots usually gets its own camera, because that is where you want a clear look at faces and vehicles.
Decide what each camera must show
A camera covering a whole yard shows that something happened. A camera aimed at a door or gate from a short distance shows who it was. Good systems use both: wide views for awareness and closer views at entry points for detail. Trying to make one camera do both usually means neither view is good enough.
Cover outbuildings and open areas
Barns, shops, equipment yards, docks and parking areas each need their own view. A pan-tilt-zoom camera can watch a large open area and follow activity, but it only looks one direction at a time, so it works best alongside fixed cameras that are always watching the entrances.
Plan for night and distance
Every view should be checked for lighting at night and for how far away the subject will be. Long driveways and gates far from the house may need a camera placed closer to the entry, with a cable run or wireless link to reach it.
Leave room to grow
Choose a recorder and PoE switch with spare capacity. Adding a camera later is simple when the ports, power and storage are already there.
Frequently asked questions
Is one wide-angle camera enough for a yard?
It can show activity across a yard, but it rarely captures enough detail to identify a person or vehicle. Pair it with closer cameras at the entry points.
Do I need a camera at the gate?
If vehicles enter through a gate, a camera there is usually the most useful view on the property, because every visitor passes it.
Can cameras reach buildings far from the house?
Yes. Cameras at outbuildings or gates can connect with a buried cable run or a point-to-point wireless link back to the main network.
