Remote Viewing Bandwidth Limitations?
We wish our system would forward a single video stream from each device, local or remote, and then reformat as necessary to accommodate each client stream request. For example, the VMS would respond to requests and as necessary output one best quality stream for the video wall, other lower quality streams to iOS and android mobile device requests, and perhaps others for port 80 HTTP requests, as appropriate to whichever clients were active and requesting streams.
Our experience is based upon an austere location 8-camera ADP local DVR with remote RASPLUS viewers across Verizon copper ADSL, with uplink (video exfiltration) rates averaging well below 768 kbps.
The central office is not bandwidth limited. There is always a remote viewer active at the office, and occasionally up to two ios devices somewhere in cyberspace also remotely viewiwng the active video.
With remote exfiltration as the limiting factor, ADP's solution has been pretty suboptimal since the DVR handles remote streams independently, completely saturating the ADSL uplink and delivering a frame every 2 seconds or worse, with occasional lock-ups.
The "A" in ADSL doesn't help, since we use the internet exclusively for video exfiltration yet 80% of the ADSL capacity is in downlink, which is used only for external interfacing with the DVR and for packet acknowledgements, etc.
We'd like to exfiltrate each camera video stream once, to a remote VMS at a well-connected location. Then the VMS should support all viewing requests, whether local or across the internet (such as iOs, etc.).
Our feeling is that ADP (or at least their local franchise) didn't really understand how to design an effective system within a link-limited environment, or else maybe all they had was a hammer (ADP DVR with RASPLUS remote viewers) and so every problem was treated like a nail. At $6K for eight cameras, we've really come to regret going with the security market leader on this install.
