What Our Customers Say

Highly recommend! Installed cameras and security system for our business with very personalized, seamless service at a great price.

I am so happy I called HM Security for my ADT alarm system. I wanted to get an alarm system to save on my homeowners insurance. I called Rey the owner at 11am and by 5pm i was already installed with my new alarm system and explaining to my husband and I how to use it. I will definitely recommend HM Security to my friends, cowokers and family for any of their security needs.

We had Bay Alarm in our facility we made some changes to our building and called for new service the price was much higher than we expected. We decided to look for another company. I called HM Security and Rey was so helpful and he came out the same day with his tech. He send me the quote for ADT and it was amazing. We are grateful and thankfull for the amazing work and support and dedication that he has given to us. If anyone is looking for a great company and services please contact Rey.
