Ghost horizontal lines on display

[JohnDesouza 0]

I have a Prama (Indian) 5 mp analog camera setup. 

Have been getting these horizontal lines in 3 of  the camera display. These are exposed to rain. Although they are under a shade and not under open sky. 

Earlier the line was barely visible only at night. But since it really rains a lot in Goa, India. Now the lines are visible in the day as well. See image. 

I am hoping this will get resolved with coax video ground loop isolator balun so ordered then.

Hi 5mp analog will not work on ground loop isolation 

5mp cameras will be HD analog ……. How are your cameras wired up can you post a picture of bnc and also the power supply

Hi, here are the pic of the power supply and the BNC connected on the DVR

So no coax insight ?? Twist any cable together 

75ohm cable is needed which is standard for cctv done in coax

standard cable 100 ohm  which you have used is not good for quality

in India this is what we use for CCTV cabling.

The Coaxial  bit  is joined to a BNC connector and  2 of the small wires are used for power, if the camera has audio then the third will be used

then we get prewired BNC connectors where the Coax cable can be linked to.

Sorry none of your pictures are compliant 

yes that cheap multi core cable has coax BUT not 75ohm ……. Then you use made up bnc cables that does not have coax it’s just 0.75 wire so your defeating the object

using cat5 with baluns is better and cheaper

you are just putting lipstick on a pig
