Example plan · House with attached garage · data checked 2026-09-16

How many security cameras do I need for the backyard and patio of a house with an attached garage without running new wires?

Plan on 2 outdoor cameras plus a video doorbell for the backyard and patio of a typical house with an attached garage without running new wires. This plan costs $220 up front and nothing a month, $220 over 3 years. Everything required is covered, but the backyard is hard to see at night. Your layout will differ, so start from this plan and adjust it.

We picked the easiest install: no new wiring, as few devices and apps as possible. This is a template result, not a site survey: your doors, trees and outlets move the numbers. Open it in the planner to match your own home.
