Hi I was referred to these forums by our AVTech supplier, I hope somebody here is able to help. We have purchased an AVtech AVC798 16ch DVR, primarily because of it's excellent connectivity for remote viewing using iPhones, iPads, Web Browsers etc. over the internet. The setup was easy enough, and initially appeared to work well, allowing remote viewing for multiple users both from the internal LAN and from the internet. Now that the system has been in place for a couple of weeks we appear to be encountering a periodic problem with loss of connectivity to all remote devices, both on the internal LAN and over the internet. The symptom is simply that nobody can connect any more. LAN connection is still good as I can ping the DVR, but it would appear that the remote access completely fails. The only resolution I have found is to restart the DVR, then everything is immediately OK for another couple of days until it fails again. I called the supplier for support, to be informed that "The AVTECHS are are bit glitchy and prone to this". He went on to say that if no more than one person connects at a time, and nobody connects for extended periods of time (say 1 hour), then the problem should not occur. This is despite the fact that the AVTech system promises up to ten concurrent connections, and suggests no limitation to the length of time for remote viewing. The system is only 2 weeks old, and I have confirmed with the supplier the it was shipped with the latest firmware. Restarting is only possible if you have direct physical access to the console, so this makes recovery of the remote viewing very inconvenient (during the Christmas break for example when nobody is on site). Has anybody else encountered this problem? and if so how do you get around it? In the event that remote access being "glitchy" is an unavoidable feature of AVTech systems, what can people recommend as the BEST DVR solution for a client requiring remote access, primarily from iPhones and iPads? Many thanks for all help received Regards Steve
