Before you choose
What to compare
Use these points to compare any home security provider, whether or not it appears on The Top 10 Experts.
Monitoring
Professional vs. self-monitoring
Professional monitoring dispatches help. Self-monitoring sends alerts to your phone only.
Equipment
Upfront or financed
Some providers bundle equipment into the monthly fee in exchange for a contract.
Contract
Term and cancellation
Check contract length and early termination fees, especially if you might move.
Install
Pro install vs. DIY
DIY kits are cheaper and portable. Professional installs suit wired homes and larger systems.
Common questions
Do I need a contract?
Not always. Many DIY systems offer month-to-month monitoring.
Can renters get a security system?
Yes. Wireless DIY systems are easy to remove and take with you.
Can a system lower my insurance?
Many home insurers offer a discount for monitored alarm systems. Ask your carrier.
