Issue with High Definition camera. Please help

RobinQi · Post by **RobinQi** » Wed Mar 03, 2010 9:18 pm

Hi! Guys: I recently purchased a 1M pixel camera but having some difficulties setting it up. The camera can run in either regular NTSC or Hi Def mode, under NTSC everything is fine, but when I hook up the Hi Def channel, the picture I saw keeps jumping left/right, up/down raplidly, it's like oscillation or something.

I set the Device Format to NTSC and Capture Palette to RGB55, Capture size is 540x480.

Obviously above setting is wrong, but I have no idea what it should be. is there a way to check?

Here is the output from "zmu -d /dev/video4 -q -v":

ntsc cant do megapixel, the std is limited to 640 x 480.

id try running the card at full res and see if that helps.

Other than that increase the frame grab setting. but id try the res first

Could you please be more specific. What do you mean by running the card at full resolution?
I wonder if my card actually support High resolution. Is there a way to tell?

well if you have a normal interline transfer cam then runnng at full res will give interlace issues.
However i would test it at that first.

What i dont understand is your '1M camera' that is NTSC?

The camera has two BNC heads. One is NTSC which works fine with my zoneminder, the 2nd BNC head is for High definition which I am having trouble with. I don't know what format of video the 2nd BNC head outputs. The manual doesn't say that, it just say it is Hi Def.

How do I do the test?

I have heard of these. As far as i know its a new high def std for coax. I was reading about it in a trade press release.
afaik there is no cards that can do this yet, however there are one or 2 dvr's.

Its designed as a std to get megapixel without ip, ie upgrades on existing cable etc.
