    It is so odd reading these reviews. I have had numerous other alarm systems in the past and they…read moreare terrific. ADT was still in the 19th century with its products and services. There was none. You had to have someone walk you through how to DIY troubleshooting to no avail and then they charged a fortune to have someone come out. Xfinity was unreliable because unless you have strong internet and not a lot of things connected to it, it works. If however, you have multiple items using the internet e.g. TV, computer, phone, Alexa etc. The signal is weak. With Vivint, I have not had any problems, I love how I can see a video of someone pulling in my driveway. At night the lights on the camera go on and a sensor beeps while it is recording. It saves the video for 30 days and you can download it if you need to. I think people need to be there when it is installed to make sure of placement for inside and outside cameras. I'm not sure I understand the comments about wiring as the only wires that I have are for the outdoor cameras and the doorbell. It would be the same with any other company. As for the technicians, you can ask for an experienced installer. However, I have had a much worse experience with Comcast/xfinity installers.

    Do NOT use Vivint for your security needs! i have been paying $53/month for two years for equipment…read morethat is in a box after moving to a location where I could not drill holes. The technician misrepresented the terms of the contract, so while they are protected it is criminal to pay over $1000 for equipment and 3 years of service while only benefitting from ONE year of service. There are too many other options for your security needs!

    I bought a home in March 2025 where the previous owner had Flex Alarms. We were told by Trent…read morePercival, as was the previous owner, that we could take over the remainder of their contract so they wouldn't be penalized. (March-Sept 2025; they had already paid for 2.5 years) They acted as if this was helping us both out. Then Trent would tell me we will be there on a day at a certain time without asking me first. I had to tell him 3 times that didn't work for me and he couldn't just tell me when he was coming. Once they showed up unscheduled at 7:45am and he texted me that the tech was here. I was leaving for work. 3 other times a tech, Zach, was supposed to come and didn't show up. The front door sensor was broken so it was silently setting the alarm off which wasn't even armed so the police came and multiple times we had to call them off from coming. Jim Anderson, the owner reached out to inform me that if I didn't pay, even though we never had service or even set the alarm, he would be turning me over to his attorney. I explained the situation and even sent him texts proving all this. He said they didn't do anything wrong and asked if we could reset. He didn't care about us or that we were told lies, misinformed, or were trying to help the previous owner not be penalized even though they moved 6 hours away! He has told me I'm not honorable, I'm not following through, and that I will be paying his attorney's fees and costs. Buyer beware!!

    One of the worst companies I've ever worked with. Customer service was horrible. I had to be the…read moreone initiating contact every time. Company customer service will never accept any blame and try to pin it on anyone else they can. Trent Percival was looking to make a quick buck instead of trying to actually help. Never reached out to help until I persistently called to get something done. Wouldn't recommend to anyone looking to have someone that does that their with pride and honesty
