"I regret ever choosing SafeStreets. The whole process was frustrating from the start. The technician who came to install the system was late, didn’t answer my questions properly, and left my house a mess. When I reached out to customer service, I was put on hold for over an hour, only to get a half-baked answer. Save yourself the trouble and look elsewhere."

Rush Security & Alarm
Rush Security & Alarm
Rush Security and Alarm is your Home and Building Security Professionals! Serving the Colorado Springs and surrounding areas we offer protection for your home and business. We pride ourselves with quality service. We proudly service the Colorado, Kansas, New Mexico and Wyoming areas.
"Working with Rush security has been highly disappointing and mediocre at best. We had multiple missed appointments with their technician until I put my foot down and said I'd cancel service if they did not show up. He started to show up after that, but just for a couple days and in my opinion still did subpar work. At first, the alarm system would not register away, only "stay". Then the doorbell camera was constantly ringing even when no one was there. The motion detector also does not work. Next, we paid $400 for equipment and a $75 monthly monitoring. I wish I would just gone with Ring because they are cheaper but I wanted to support local. When we asked to cancel we were told we'd have to pay a 1400 cancellation fee to recoup the loss of having an electrician come out and for the 'low' $75 monitoring and to buyout the contract. Initially, we were told they offered no contract service, which was the only reason we went with them. I did the math and that 1400 fee would total out to about 1.5 years of subpar service. No thanks. We took the loss but you do not have to, go with someone else or just install your own alarm"
