Yesterday I decided to finish writing my paper and wrote an additional four pages and my computer suddenly ran into a problem and automatically shut down. The system should have auto saved everything since it's programmed to save every 10 minutes, but it was all gone and all I could see was the two pages from the days prior once my computer started up again. I was in panic mode and did not know what to do. Thank God I came across this yelp page and called Ron. He did some troubleshooting, trying a few different things after remoting into my computer. He was able to relocate my lost document and I felt like I won the lottery. Thank you so much! Saved me hours

California Security Pro…read more Home security has never been my favorite topics, at first a bit confusing there's network apps, motion sensors and connected door alarms all of which seem to work flawlessly together. We called two places ADT corporate and California Security pros.    Bill Wood approached us in August 2016 after buying new house. Many of us have had that one teacher who makes it all click together they are often energetic and fun seemingly always at the top of their game. Bill's smile, genuine personality and willingness to teach difficult subjects to us made him the clear choice a 2nd time this summer when we installed ADT at our local Napa Business. We feel great knowing who to call and who to let in our house when our batteries need replacing. Communicating via text message and follow ups afterwards were "Better than Expected" Thank you!

I was a Deep Sentinel customer with wireless cameras and wanted to upgrade to wired. Jose designed an entire system with me and worked to coordinate his work with the remodeling. By doing this we were able to run all cameras with virtually no conduit and made the entire system seamless with our house. Jose worked so hard for us and worked with us when he had to make extra visits due to coordinating with construction. I know he did more work for us than originally estimated but the final job was 1000% amazing. I would recommend Jose to anyone!

Two promptly came back with bids within 24 hours. One, Bay Alarm set expectations they needed more days and even a weekend to prepare the bid. The weekend came and went without a bid showing up. By Thursday afternoon, a week after the other bids were in my inbox, I called in only to find out the service technician was still working on it. A week after he said we'd have it to us, and long after the others had arrived, still working on it. It made me pause. Naturally I was wondering exactly how long it would take them to call the police if my newly installed security alarm were to go off in our home? Always under commit and over deliver, not the other way around. Confidence shaken for sure.
