he estado usando Zoneminder hace unos años y ha funcionado bastante bien, recientemente he entendido varias de sus configuraciones, pero ahora me encuentro detenido con un problema que no puedo resolver, 1 de mis monitores tiene la imagen dividida (adjunto imagen).

Si alguien porfavor puede ayudarme, he intentado diferentes metodos de configuracion y no funciona.

Gracias , de antemano.

Check "CAPTURES_PER_FRAME" setting (options::config). Or possibly disable "V4L_MULTI_BUFFER" (options::config). If neither of these fix the problem try Video for Linux 1 in the monitor source settings. One more thing I just noticed, try changing the palette to BGR24 unless your sure the one selected is correct (palettes seem to have changed with 1.24.2).

Thanks bb99, tomorrow i will try this.

But anyway , thanks.

Just realised I never gave you a value for "CAPTURES_PER_FRAME", it should be 2 or possibly 3. Be patient in between changes, takes awhile to actually see the change after save.

the way fixed this problem was to....(in ver 1.22.2)

1. Make sure all monitor settings on the card in use are the same (i.e. resolution, FPS, ....)
2. Set max FPS to 2 or 3 On ALL 4 channels
3. Click on "Running" and restart the service (not the DVR)
4. Connect Cameras to all 4 ports

this has always resolved my problem and then i could increase the fps to 3 or 4.


also under EACH camera settings go to "BUFFERS" and set the following settings(will also reduce cpu load as well as help resolve the problem)

Image Buffer Size (frames) 20
Warmup Frames 10
Pre Event Image Buffer 10
Post Event Image Buffer 10
Alarm Frame Count 1

Thanks for your help,

i've just applied the settings , anything i'll post it here.

Best Regards.

Hi,

after a complete day testing , i can say that it works...

thanks for your help, now i can Modect ...

Bye.

Perfect! Please edit the title to include "solved", makes searches easier for the next person with the same problem.

Glad i could help!

Your next priority should be to get rid of that Cheap China Card and get something nice..... or keep it for the cams that arent imporant.
