Recently split the output on a cctv camera. 1 monitor get static and the other doesnt. how can i fix this?
Im installing a camera system at work. 2 cameras have a split BNC output running to the DVR as well as a monitor for the machine operators. but the operator screens have static on the bottom 1/4 of the viewing screen. what can i do to correct this.
Its running off a 120v camera and the wire i installed is a 75ohm rating. i dont know the rating of the older wire.
I bought commercially produced splitters and i even tried different ones but there has been no change.
Any ideas?
Is the signal clear when JUST the monitor is connected?
If so then you may simply lack enough signal to go through the split to both the DVR and the monitor. You may need to rewire this using a pass-through on the DVR (signal from camera goes into DVR, and then comes back out of DVR and to operators monitor). An amplifier may help, but you'd have to experiment with it's placement to ensure both the monitor and dvr receive useful signal.
Another problem could be inductance, where your CCTV wire is run beside existing electrical wiring.
You may also want to consider the length of the run and what kind of cable is used for the cameras, as older cable may be more prone to interference, signal loss (rg59 instead of rg6) or may have become damaged (cable nicked, cut or stapled).
Hope this was some help.
