Your camera's dying. Spend more, get more.

Looserguy,

I can not get into the link that you gave. The reason I asked you to record into bigger size is that the camera gives your DVR, as good as D1 size video. But it seems that DVR scales down to CIF(a quarter of D1), for recording. If color components are not scaled down properly, or hard compression to save recording file size, then such pseudo color artifacts can be appearing.

You can narrow down the issues when you plug the camera video out directly to your TV to check whether it is from camera.

i fixed the link. Please try again.

I couldn't get the d1 dvr option when i was using the dvr main program directly on pc with the dvr card. Yesterday i connected remotely with dvr-net and using the remote setting option i was able to change to d1 option. I asked for camera distortion because i have connected video and power cable by twisting the pairs without using plugs and concerns me that probably that is the cause.

 

Thanks for you time

Do you mean that your D1 sized video can be displayed without those color artifacts at the edges?

No. In both recording sizes the same color artifacts. I meant the main program gave me only cif option for recording. When i used main program remotely with dvr-net i was able to change to D1 option

Can you go to your place and plug the camera output into a TV set? This is for identifying who's fault, camera or the card.

Can you take picture of your DVR PC capture card and post it?

I like to know the manufacturer of chipsets on the boards. Judging from the video clip, I guess the card is pretty old type.

Let me inform you that there are also 4 more cameras same model in this place that work fine.

Probably i go to this place the next week.

The dvr card model number is nt-08120

looserguy,

I checked out all pictures that you linked.

That's pretty old model-hardware compression card,based on MPEG4.

I thought those color artifacts coming from scaling down to compression and scaling up for display as there are not enough color pixels for interpolation.

That's why I asked you to plug the camera output directly to a TV set, as the original D1 size of being captured, not scaling involved.

Simply bring another camera as well when you go to the place. The camera's probably gotten aged to retire.

looserguy,

If found the camera is ok, please let me know.

We just developed a PCI-Express 8Ch capture card (software compression) under promotion. If interested in, please leave a mail to my PM (private mail)box in this forum.
