Question about Pelco CCC1380UH Series High Resolution Compact Camera
Camera system install via tt560 tramitter and tr560 receiver using phone line dvr showing lines through picture
First some quick information on your UTP Devices...
Twisted Sender is recommended for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 26 AWG through 12 AWG but are optimized for 24 AWG. Category 2, 3, 4 or 5 cable may be used. Individually shielded pairs should be avoided as they drastically reduce the operating range of the systems. Multi-pair cable with an overall shield is acceptable (but do not use the shield). Video can be operated in the same communication cable coexistent with telephone, computer, control signals, power voltages and other video signals. While video may be routed through telephone punch-down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair. Did you do this on the existing phone line?
What you are seeing is a ground loop. So that tells me there is something along your cable run that is changing the ground potential. (difference between your cameras’s ground and your DVR’s ground) I would check your phone line for bad connections and to make sure you don’t have any resistive capacitive or inductive devices still connected. Or you can use a GIT100 that Pelco (800) 289-9100

May be bad connection or need larger gauge wire.
