Axis 215 resolution

[ozirisra]

Hi,

I have configured Zoneminder to work with Axis 215, but I have trouble with the resolution settings.
320 x 240 works almost fine, although I get the upper part of the picture I expected.
When I change the resolution to 640 x 480, which I need, I have no picture at all and the source turns from green to red.

My configuration is as follows:

Source Type Remote
Function Modect
Enabled True

Remote Protocol RTSP
Remote Method RTP/ RTSP
Remote Host Name root:password@ip
Remote Host Port 554
Remote Host Path /mpeg4/media.amp
Remote Image Colours 24
Capture Width 320 /640
Capture Height 240 / 480


Is there any additional setting that I'm not aware of?

Thanks.
