So we looked around more for another installer and found one ( I also reviewed them). Oh, I called and made another appointment with Data Installers...still waiting. In the meantime the other guy came out and fixed the problem as scheduled.

Numerous calls to their Un-Helpful Center and visits by other Field Technicians have been just a big waste of time because nobody could figure out how to record more than 2 shows at a time despite the fact we are supposed to be able to record at least 4 shows and still watch another channel. Andrew Flores would not give up. I listened as he called repeatedly to various departments and support people until he traced the problem down and fixed it. As a side note, Andrew has a good sense of humor and has a remarkable resemblance to a young Adam Sandler. Hey Adam, you're always creative with your casting; you should find a place for an Andrew in an upcoming project. You won't be disappointed.

No one will let me speak to a manager and no one seems to know what to do. Just trying to talk to a person is so frustrating, all they do is prompt you to use the app or text.

It's such a shame this company I've been so happy with for almost four years SUCKS.

We had a full security camera system installed at our home in Upland, and the peace of mind it has brought our family is priceless. The team showed up on time, walked us through every option, and helped design a system that covered all the important areas--front door, driveway, backyard, and even our side yard where we've had concerns before. The clarity of the footage is amazing, and we love being able to monitor everything from our phones when we're away from home. David and his team was friendly, knowledgeable, and truly cared about making sure we felt secure and confident in our setup. If you're thinking about getting a security system for your home, don't wait--Calderon Technologies is the team to trust. Five stars all the way!" -- Robert Z., Upland, CA
