Home Security System Cost Guide
Understand the major cost factors behind a home security system, including equipment, installation, monitoring, wiring, and smart home add-ons.
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. |
Common budget levels
| Budget level | Good fit | Possible setup |
|---|---|---|
| Basic DIY | Townhomes, condos, smaller homes, or research-stage buyers | Video doorbell, 2-4 door/window sensors, one indoor camera, app alerts, optional video storage. |
| Balanced homeowner setup | Most single-family homes | Video doorbell, outdoor camera coverage, entry sensors, motion detection, smart lock, and optional monitoring. |
| Full monitored setup | Larger homes, higher concern areas, frequent travelers, families wanting response support | Multiple cameras, full entry sensor coverage, glass break sensors, smoke/CO monitoring, smart locks, keypad, and professional monitoring. |
