All of our installation technicians are internal employees, and not third-party contractors. You can count on your Security Advisor to take the time to set up your system properly, help you understand how the system works, and help make sure your home and family are thoroughly protected.
"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system.

"Fantastic outcome! I was initially convinced replacing my circuit breaker panel would solve my many house electrical problems. Owner Bill convinced me the intelligent/logical approach would be to trouble shoot everything before committing to same. Their staff identified several problems and professionally fixed everything at a very reasonable price. I expect to eventually upgrade the circuit breaker panel but will cross that bridge when necessary. In the meantime, very happy with how fine everything is working now. Wonderful Experience!!!"
