Tenvis IP Cameras - no video feed (SOLVED)

[nugget]

A new thread - originally posted in the Zoneminder 1.25 forum. I've just upgraded to 1.26.5 and my problem remains.

A new installation of Zoneminder 1.25 (now upgraded to 1.26.5 with ffmpeg turned off) on Centos 6.5. I purchased a Tenvis IP602W and managed to get it working reasonably well using the remote HTTP feed (/videostream.cgi?user=User&pwd=Password&resolution=32&rate=14). The resolution is a bit so-so, but I can live with it.

Making the assumption the IP602W worked reasonably well, I have since purchased a Tenvis IP391W-HD. I think this is a reasonably new model, it is 720p resolution and claims to do H.264 video streaming. I've all but given in on the H.264 for now, and wanted to do a simple configuration using HTTP/videostream.cgi, unfortunately I'm unable to see any video feed in the monitor window.

In a Firefox browser I'm able to view the feed (at 640x480), eg: /videostream.cgi?user=User&pwd=Password&resolution=32&rate=14; the stream is stable and looks like the sort of thing I'm expecting (based on my experience wit the previous Tenvis camera). Unfortunately Zoneminder does not display any video (just the "broken jpeg" icon).

My last troubleshooting was to turn on debug and compare the output between my working and broken cameras:

There is an obvious difference in the startup HTTP get (Got boundary '--ipcamera' vs --pictureboundary), so it seems to me I have a configuration problem, which is the limit of my knowledge at this point.

I also recieve the following in the ZM error log:

Can't open memory map file /dev/shm/zm.mmap.2, probably not enough space free: Permission denied

Which confuses me - all research points me to shared memory sizes, the defaut shmmax for Centos 6.5 is 64 GB. Any ideas?

Both cameras are configured similarly:
Source type: remote
remote protocol: http
remote method: simple
remote host IP/port (is correct)
remote host path: /videostream.cgi?user=<user>&pwd=<password>&resolution=32&rate=14
target colorspace: 32 bit color
Capture width/height: 640x480

Connecting to the camera via a web browser returns expected results (http://<IP-addr>:<port>/videostream.cgi?user=<user>&pwd=<password>&resolution=32&rate=14 - both cameras are working fine. I should point out there is an onboard software difference between the 2 cameras - they are Chinese clones of something (unsure what at this stage), both cameras appear to be from 2 different OEMs as the software is completely different.

Any ideas? I'm approaching the point where I bin the new camera and find an affordable IP based substitute.

Tenvis IP cameras - I'd rate 6/10. Cheap; but support is lousy.

I've managed to get my IP391W-HD working, but not using the "advanced features" of this camera, ie 720p and RTSP streaming.

For a $110 IP camera at 640x480 it's a nice build, OK resolution. The case and mount of this camera is excellent - once bolted to a wall it would take some effort to disturb the setup of the camera, for positions where the camera is easily accessible (eg my front door) this is a feature I need.

In the hope of helping others out, the settings I've used are as follows:
General:
Source Type: remote

Source:
Remote Protocol: http
remote method: simple
remote port: 8001
remote host path: /snapshot.cgi?user=admin&pwd=<password>&resolution=32&rate=6
Target Colourspace: 24 bit colour
Capture width/height: 640x480

RTSP may have to wait; I am in no hurry to solve that particular problem.
