Camera

[Rousey75]

Hi I am from the uk and just built my first rov done all the necessary checks and works fine once I got past the buoyancy issues. I have used a cheap cctv camera but can't even get it to show a picture on tv my tv. Don't the usual by using a 12v supply and used a 25m av cable with av and audio. Picture is very poor so I assuming quality will be lost due to the length of the av cable. Any ideas on what to do. Thanks paul
