We had installed 10 PTZ cameras in line over 10 Kms dropping 1 pair of fiber at each camera location. Now the problem is Video from all the cameras are being displayed clearly, but the data (PTZ command) is working for only 1-2 cameras . earlier it worked well for 7 cameras. We had used ONV make Fiber convertors. My doubt is - if video is crystal clear from all sources , then why the data is not operating. I had also checked for all type of RS 485 leakage, terminations etc. Also tried installing single camera over 7th KM (removing all other cameras ) but in vain. PLEASE HELP SOMEONE.

hi all, would like to share knowledge and gain from your experiences.

Locally Each PTZ are working fine (tested with Keyboard)

already done that but in vain.

we had installed ONV fiber transmitters and receivers with PTZ. cable length is 10 kms , SM is there a possibility that video is shown but data does not works?? as we are facing this issue. At the time of installation , the system was perfectly running but on an average every 3 months one camera stops moving (Video is still displayed clearly)
