This guide breaks down every cost component so you can budget accurately and avoid surprises.

Equipment Costs

Starter Kits

Most DIY brands sell starter kits that include a base station, a few sensors, and sometimes a keypad or camera:

SimpliSafe Core: ~$120 (base, motion sensor, 2 entry sensors)
Ring Alarm 5-Piece: ~$200 (hub, keypad, contact sensor, motion sensor, range extender)
Abode Iota All-in-One: ~$200 (hub + camera combo)
ADT Self Setup: ~$100 – $300 (depending on kit size)

Individual Components

How Many Sensors Do You Need?

Apartment (2 BR): 4 to 6 sensors, 1 to 2 cameras
Small house (3 BR): 8 to 12 sensors, 2 to 4 cameras
Large house (4+ BR): 12 to 20+ sensors, 4 to 8 cameras

Installation Costs

DIY Installation: $0

Brands like Ring, SimpliSafe, Abode, and Wyze are designed for homeowner installation. Setup typically takes 1 to 3 hours. No drilling required for most sensors (peel-and-stick mounting).

Professional Installation: $99 – $499

ADT: $99 to $199 standard installation fee (often waived with promotions)
Vivint: Free installation with 60-month contract, or $199 without contract
Local alarm companies: $150 to $499 depending on scope

What pro installation includes: Running and concealing wires, mounting cameras at optimal angles, configuring the control panel, testing, and training.

Note on Hardwired vs. Wireless

Hardwired systems typically require professional installation. Wireless systems are DIY-friendly and are the dominant standard in 2026.

Monthly Monitoring Fees

This is where many buyers underestimate total cost.

Self-Monitoring (Free)

Brands like SimpliSafe and Ring allow self-monitoring: you get app alerts but no professional dispatch.

Professional Monitoring Tiers (2026 Prices)

Key difference: ADT and Vivint lock you in with 36 to 60-month contracts with early termination fees of $400 to $1,500. SimpliSafe, Ring, and Abode are month-to-month.

Hidden Costs to Watch For

Permit fees: Some cities require alarm permits ($25 to $100/year).
Cellular backup fees: Some providers charge extra for cellular backup.
Camera cloud storage: Camera subscriptions are separate from security monitoring on most platforms.
Equipment upgrades: Proprietary systems (ADT, Vivint) may lock you into buying their hardware.
Early termination fees: Breaking a 36 or 60-month contract can cost hundreds.

How to Save Money on Home Security

Buy during sales: Black Friday, Amazon Prime Day, and back-to-school sales regularly discount starter kits 30 to 50%.
Choose DIY over professional install: Save $99 to $299 upfront.
Avoid long-term contracts: Month-to-month plans give you flexibility without penalties.
Use cameras with local storage: Avoid per-camera cloud subscriptions.
Check homeowner/renter insurance discounts: A monitored security system can reduce your premium 5 to 20%.
