Home Security System Cost Guide

What this guide covers

Home security pricing usually includes three parts: equipment, installation or setup, and ongoing monitoring or video storage. The right budget depends on how many entry points your home has, whether you want cameras, and whether you prefer self-monitoring or professional monitoring.

Common home security cost factors

Cost category	Typical planning range	What it usually covers
Starter equipment	$200 to $400+	Base station or hub, a small number of door/window sensors, and basic motion detection.
Additional sensors/devices	$20 to $300+ each	Extra contact sensors, motion sensors, glass break sensors, cameras, smart locks, smoke/CO devices, or keypads.
Professional installation	$300 to $1,238	Labor, setup, mounting, wiring needs, camera count, and system complexity.
Wireless system	$200 to $2,000	Often lower upfront installation effort, app control, and flexible device placement.
Wired system	$800 to $1,600	Professional installation, wiring, more permanent setup, and less Wi-Fi dependency.
Monitoring	$10 to $65 per month	Professional monitoring or service plan features, depending on provider and plan.
