How many security cameras do I need for every side of a house with an attached garage without running new wires?
Plan on 5 outdoor cameras plus a video doorbell for every side of a typical house with an attached garage without running new wires. This plan costs $720 up front and nothing a month, $720 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 this device configuration in the planner to match your own home. Device quantities, ownership and mounting positions are preserved. Coverage here uses the legacy specification-based engine; the interactive editor uses an illustrative view and recalculates shopping from current offers. These hardware-and-plan figures exclude unlisted storage and installation costs.
