    Joseph P.

    Sergio was GREAT! Texted him and got back to be with questions on what I needed, told him I wanted my new 75in tv mounted on my living room wall with a full motion bracket and to hide the cables thru the wall. He emailed me a quote and let me say that it was a better deal than anyone else or company. Came in right on time at 9am and by 10am he was done, he even installed some led color strips behind my tv that change colors. My wife and I are very happy with his work and will get our room tv's installed by Strong Security in the near future. Thank You Strong Security.

    I have used Valley Alarm for yours. Recently had problems with it and they came out at a reasonable…read moretime and fixed it. The serviceman was knowledgeable, kind and fixed the problem within a few hours. So happy for Valley Alarm being so professional and prompt!

    We've been a customer of PV Security for decades, which was bought by Valley Alarm and absorbed…read moreinto their system years ago. Had assumed all these years that our house security was adequate but recently was horrified to experience that it very much was not, and more importantly, that the folks at Valley Alarm were not trained properly, made a ton of mistakes, and made for a very stressful holiday. The day before Thanksgiving, we received text alerts of a burglary - nothing else. No idea if this was a fake text or anything, as it provided minimal information (the title: BURGLARY) . Everything that transpired after was across the board an extremely negative experience: 1. I had to call Valley Alarm to get more info. Each time I called, I was on hold for at least five minutes - terrifying when you've just received a text saying BURGLARY. To add insult to injury, the hold music is an advertisement for VA saying that "agents will be on the phone in seconds." 2. I spoke to multiple agents, and none provided sufficient information or answer any of my questions adequately in a way that would reassure me. 3. Horrifyingly, I had to be the one to tell VA to CALL THE POLICE. They were supposed to have called me first, and immediately dispatched the police. Neither happened. In fact, when I called the first time, the agent was a very blase "oh, do you want us to call the police?" Uh YES. And then once that happened, they provided zero follow up information. I eventually found it easier to call my police station directly, and speak to the police via my neighbors. 4. ALL OF THIS WAS A FALSE ALARM. Valley Alarm NEVER provided an explanation of why we had received an alarm. The neighbors never heard the alarm, and when we had someone check the house, there was no sign of anything amiss. 5. After all of this (and before we were able to have someone enter our house) I called VA repeatedly to make sure that our alarm system was still actively armed. Every person gave me a non-answer in the form of double negatives: "well, if nobody has gone in to disarm the alarm, we can only assume it is still armed." Not only was this absolutely not reassuring, and felt like they were hedging their bets, it turned out to be completely incorrect - they just straight up had no way to tell, blaming us for having an old system (which they had never told us to change) and for not performing routine checks (which they had never told us to do). 6. 3x I had their "service technicians" call me to "provide more info" because the agents at the call center were proving to be completely useless. The first time a technician called, she literally started the phone conversation with "what do you want." I was never assured that our house was okay and that the alarm system was still working because none of these agents or technicians could provide straightforward information. I am just horrified with how badly this entire experience went across the board. Valley Alarm has admitted that there was a lot of human error after they looked into this experience, and I have never been more certain or faster in changing companies. I have a new system that provides me with way more information, and doesn't keep me on hold to speak to an agent. Absolutely stay away from Valley Alarm.
