Analog camera splitter issue

[phoenixr1 0]

I have a Computar ZC-D5212 that is split between a small pelco analog monitor, and our main system, which implements Nextiva encoders. The camera picture intermittently exhibits thick black lines, strong picture fluctuation and other problems. I initially chalked this up to a splitter issue, and replaced the splitter. Then it seemed to be a cable issue, and eventually I replaced entire cable. When this did not fix the issue, I replaced the camera itself. Now, the new camera is beginning to exhibit these same symptoms, but the issue has ceased now that I removed the splitter altogether. I'm using a standard 2-to-1 or 1-to-2 BNC splitter. Anyone have any ideas why our main system seems to not like this splitter?

The answer is right there in front of you: "the issue has ceased now that I removed the splitter altogether."

 

Splitters CAN often work just fine, but they are never an ideal solution, because you're reducing the signal to each device by 50%. Worse, if one of the devices doesn't present the proper load to the signal, it will cause an even greater loss to both of them, as well as increasing the risk of ground loops and susceptibility to interference.

 

What might help, is if this monitor has a looped "video out" jack on the back - most good CCTV monitors will properly load this pass-through jack, and you should be able to feed the camera into its input, then run from its output to your encoder. Of course, there's no guarantee this will be 100% either, but it should be better than what you're doing now.

 

The best solution, of course, is an active video splitter.

Thanks! I had already deduced that the signal didn't like being split, I just didnt know if i was using the wrong kind or ifor if there was another issue.
