Mar Vista Security And Intercoms Systems - Installed new tektone intercom front

Mar Vista Security And Intercoms Systems

Mar Vista

I recently contacted Mar Vista Security and Intercom Systems about upgrading our call box. My…read moreinitial plan involved spending around $3000 on new hardware and installation to go from land line to cell-based, plus dealing with an ongoing monthly bill of over $50. But Jack turned that around completely with some fantastic advice over the phone. Instead of pushing for an expensive upgrade, Jack recommended switching our land line provider from AT&T to Spectrum. This simple change would save us over $300 per month without needing to touch any of our existing equipment--and he didn't charge a dime for the consultation! We're talking $30 a month for a business landline with Spectrum versus the whopping $360 we were paying AT&T. Thanks to his pointer, Spectrum is coming out tomorrow to handle the switch and finally rid us of that overpriced service. What really sets Jack apart is that he was the only one out of several companies I contacted who actually suggested this smart solution. The others either ghosted me or tried to upsell unnecessary work. Jack's honesty and willingness to help, even if it meant no immediate business for him, speak volumes about his integrity. If we ever decide to upgrade the system or add cameras in the future, Mar Vista will be my first call. Highly recommend--5 stars all the way!

David made 2 visits to our home to install Reolink WiFi surveillance cameras and also to fix an…read moreelectrical issue in our garage. The first time he came with his assistant Oscar to work on the cameras. The two of them worked together on a really hot day, and they got all the cameras installed exactly where I wanted them to be. We discovered however, that the WiFi Modem/Router I had was not pushing the signal far enough. David suggested that I purchase a Wire Mesh Router called an Eero, which would increase the signal to all the cameras. At his recommendation, I purchased the Eero but ran into problems when connecting it all up. But David was right there to help me. Since I also needed some electrical work in my garage, David came out again and diagnosed the problem and created the solution. He then went to work on my Reolink network and saw that I had incorrectly connected the Eero. Once that was connected, it all seemed to be working fine. I would hire David again in a heartbeat and would recommend to others that they do the same. David AV has five star reviews for a reason: it's deserved! It's so nice to find truly professional people like this. Thanks again, David and Oscar!

He took the time to understand exactly what height I wanted and made sure the placement was just right before mounting it. He was professional, meticulous, and respectful of my preferences. The TV looks great, and I'm very happy with the finished result. I would definitely recommend David AV to anyone looking for quality TV mounting!
