camera screen freezing for few seconds

[cycop 0]

I am using kodicom 416 card connecting to 4 cameras using motion detect turned on. When there is an activity detect on 1 of the cameras, the camera screen freezes for few seconds and sometimes does not even capture the activity.

This problem does not happen when I am only using 2 cameras.

What could be wrong?

Low signal, low light, motion detection too high... all have caused that effect for me.

what does Low signal means?

bnc wire is bad?

 

could it due to PC or DVR card too?

[UMDRanger 0]

Bad connection at BNC (shield touching core, core damaged, etc), too many connectors causing signal loss, or who knows!

 

For example, I have 16 cameras on a Javelin switch. Those 16 cameras come off a Multiplexer. Cameras are a mix of PTZs, stills, 24AC and 12VDC. I have the Javelin input into a Geovision 800-4, allowing me to choose any 4 out of 16 cameras to be recorded. But for some reason the Geovision won't accept some of the cameras, including the 24VAC PTZs. Some work, some don't.

 

Aside from trying to swap out some of the parts or cable, not much else I can tell ya. Start troubleshooting it, each part at a time, until you find the problem.

I tried with another BNC cable the motion detection screen freezes too.

I am think if that could be due to DVR card problem now

 

any idea how to confirm that?

Have you tried different settings? Like constant recording verses motion? How about adjusting the motion sensativity?

 

Otherwise, it'd mean trying a different card

i tried with different DVR settings same problem.

how do i enhance the signal for BNC cable?

Can you take a camera, and plug it in directly to you PC DVR?

 

If the cable was a long run it would cause a voltage drop that the camera may not agree with. If it is a long run then the video may fall apart before it gets to your DVR.

 

If you can try a camera locally this will tell you if it is a power/video problem or the DVR itself.

 

What kind of mother board are you running? What chip set is it?

video acceleration settings? lower that setting........

 

motion causes PC based DVR's to "jump" in CPU resources........

i tried connecting the camera directly to DVR same problem.

i am running it on P4 1.8GHZ with 1GB RAM

Why the problem does not happen when i only have 2 cameras?

4 cameras uses more CPU and memory than 2 cameras.. and like VST said, also more from the video adapter.

 

Note: As far as we know only Kodicom builders have the cards, so is this a legit card or a ready built Kodicom System; or did you buy the card from somewhere. Unfortunately we cant assist with pirated cards.

 

Thanks
