ZoneMinder Forums

Hello All:

I am running Zoneminder 1.24.2 on Ubuntu. My capture card is a PV-143 with all four channels in use. The computer system is a dual Xeon 2.8 w/2gb of ram.

This system has been up and running and has been stable for nearly four years. I have updated Zoneminder when possible along the way.

However, I have never been able to achieve greater than 320x240 resolution on any one channel. I have the channels set to run at 5.00FPS with an alarm rate of 5.00FPS. The cameras run under NTSC with the capture palette set to RGB24.

If I ever try to increase the resolution greater than 320 x 240, the channel turns red.

Is this a limit due to the PV-143 capture card? Or does this have to do with my system hardware?

Any help would be greatly appreciated.

Thank you.

PV-143 card is a single 878 chip that allows up to 4 cameras being attached. Because it's only got one chip all monitor settings have to be identical for all cameras attached or the one you make different will fail. So to increase resolution on one you must then do it to the rest and all will be fine. Don't forget about shared memory......
