Corrupted captures causing alarms...

Sometimes I'll get alarms where the frame looks weird like:

What causes this and is there anyway around it??

Thanks,

Is this for a regular video camera or a netcam? I've seen images like this on my regular cameras for a while when I had some cabling problems with the sheidling and earth.

Thanks for your response.

It's a Creative NXPRO webcam. Since the original post, things got a lot worse...the image capures started becoming more and more corrupted, with constant alarms. I tried restarting ZM, removing the cam and setting it up as just a monitor, but the corrupted images kept coming. I then rebuilt the webcam driver and reloaded the module in the kernel, and now the image appears to be fine. Not sure why that would make any difference? I'll let you know if things start getting funky again.

Thanks!

Adam

Is that a USB cam? They can be a bit hairy as the bandwidth isn't always managed optimally in the drivers.
