We have been contacted 2 times. Dahua video intercom repair. For the first time, they asked me to bring them for diagnosis. As a result, they forgot about our order and the panel lay ready in their office for 4 days, but no one called. The second time (because the panel turned out to be working and the problem was not in it) they have already been sent to the installer. The installer first offered to look at the power supply themselves, because he has a long way to go. Although it is not clear to me what to watch there and if I knew, we would not have contacted the service. And then Vitaly disappeared altogether.
A great store for acs and video. I know Yuri well...., tech support is really lame..There are prospects for growth, good ideas, and projects for development!!
