Why Activate With The Monitoring Center?
Pay less, protect more. We provide dependable, UL-Certified monitoring with in-house customer support and six months free when you activate today.

Lowest Monthly Costs
Our monitoring plans start as low as $9.99 per month, giving you reliable coverage without paying premium prices for the same police, fire, or medical response standards.
Compatible With Existing Systems
TMC can take over and reprogram most wired alarm systems, allowing you to activate monitoring without starting over or buying new equipment.

Get Started TodayWhat Our Customers Say
Rated 4.8 stars on Google based on 400+ reviews.
Switched from ADT and saved over $40 a month. The team was professional and the transition was seamless.
Great service and lower rates. They were able to monitor my existing system without any issues at all.
Transition to TMC could not be easier or more efficient. If you have a wired service your cost will be 1/4. Could not recommend them highly enough.
Frequently Asked Questions
Can you really use my existing alarm?
Yes. TMC can activate monitoring on up to 98% of existing alarm systems including wired and wireless systems from all major manufacturers — without replacing your hardware.

Many older systems are still compatible. Call us with the brand/model of your keypad or panel and we'll confirm compatibility quickly.
