How many security cameras do I need for every side of a house with an attached garage with no monthly fee?
Plan on 3 outdoor cameras plus a video doorbell for every side of a typical house with an attached garage with no monthly fee. This plan costs $250 up front and nothing a month, $250 over 3 years. Every required area is covered day and night. Your layout will differ, so start from this plan and adjust it.
We picked the plan with the lowest 3-year cost that still covers every required area. 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.
