What home security systems cost, what drives the price and how the main options compare.
This section answers the question most shoppers start with: how much will a home security system actually cost? Quotes usually mix three different kinds of money, which are equipment, installation or activation, and the recurring monitoring fee. Looking at only one of them is the easiest way to be surprised later.
The guides here break a typical price into its parts, explain why two houses of the same size can get very different quotes, and compare do-it-yourself kits with professionally installed systems. You will also find a plain explanation of monitoring plans, a look at camera and video doorbell costs, and a practical guide to negotiating.
All dollar figures in these guides are labeled as illustrative ranges, because equipment and plan prices change often and vary by region and provider. Use them to understand structure, then get written quotes for your own address. The calculators in the Tools section let you plug in the numbers from those quotes and see the multi-year total.
