System Monitoring

Why not go with the best?

The systems we install in homes and businesses are monitored 24/7 by Sacramento-based Total Monitoring Service (TMS).

When an alarm is activated, TMS immediately acts per the customer’s instructions on file.  TMS also contacts the customer when a low battery or other trouble is detected in the system. All activity is reported to High Country Security.

TMS is more than your typical monitoring station.  They adhere to high standards taking pride in meeting and exceeding customers’ expectations.  

They are the best. They are always available and willing to be there when you need them. I would highly recommend this company. We have had no issues since they installed our alarm. They were very professional and a pleasure to have in our home. I feel so much safer now.

Happy Customers

Bringing peace of mind to Northern California.

Craig and Bradley are great to work with. Just about anything you need, they can do. They are both very knowledgeable in the equipment they use and all the new stuff going on in the world with security features. They have great ideas on where to place cameras for maximum view and security. I highly recommend this company for all of your security needs.

“My system has been in for a few months  and I’m really happy with the functionality and the convenient app that comes with it. The installation went great. We couldn’t be happier with the whole experience.
