They extended my contract an extra year without even telling me, just casually expecting me to sign off on it. When I refused (because who wouldn't?), they ended up not even finishing the install -- leaving me with ugly holes in my wall and zero accountability. Apparently, your home is just collateral damage in their rush to hit their quotas. Customer service? Forget it. Transparency? Nonexistent. Special thanks to Rey Zendejas for the stellar experience (note the sarcasm).

We were looking around for a security camera installer and stumbled upon their fantastic reviews on Yelp and Google and they did not disappoint! I gave them a call and they came the same following week! We had 8 CCTV cameras installed, and the quality of both the equipment and the installation is high quality and truly top-notch. What impressed me most was the speed and professionalism. They got all 8 cameras installed and set up within 4 hours!! The last place that did my installation took almost a week to complete lol. Pricing is fair, you get what you pay for! Bobby handled our install, and he was absolutely knowledgeable and professional from start to finish. He clearly knew his stuff and made the whole process smooth and easy! 1000% would recommend to everyone looking for reliable, high-quality camera installation.

He gave us a great price (and a piece of mind) It was a fast and painless procedure! Blake set us all up with the alarm we needed. Skyline security's agreement/contract was simply stated. The promise was kept on the date the technician would arrive. Joesph, the tech, arrived right on time, worked diligently, explained everything to us at the end, set us up with out password, and off he went. We have been extremely happy with this company! Highly recommend!!!!! Love the name Guardian too.... feeling protected

The techs are OK, but their salesman, Doug Spencer, in Utah (West Valley) ghosted us for 6 weeks…read morebefore we gave up and went with someone else. Their loyalty department in California gave me the runaround and lies every time I called and asked them to help me reach a different salesman or a manager to help us since we couldn't reach Doug. They said they kept trying but no one would respond. When I (by myself without their help) finally found a manager and a tech, they said no one had reached out to them. (And after telling Jack Kelly, the local Utah manager about Doug Spencer ghosting us, and about the lies and mistreatment by the loyalty department, he ghosted me too after telling me to reach out to the loyalty department and they could help me. Seriously?) The Loyalty Department offered me compensation for the 6 weeks of lies and headaches and not having a working system (they had put in some equipment, then stopped when they needed a part...I didn't see them again until I told them 6 weeks later to come get their stuff out of my house). Anyway, they deny ever offering compensation and won't even discuss it with me saying it was never offered and isn't going to happen. Every message I left for someone to call me was ignored, I had to retell my story every time I called, and the Rep named Camillo yelled at me because he refused to believe a different Rep (Stalin) offered me compensation (he was just too incompetent to put it in his notes, which was a common theme that their notes on my calls were completely inaccurate.) Run far away from this company. There might a good egg in there somewhere, but most of the carton is rotten. ​​
