Great clear sound. Heres what I did. I didnt attach this to my cameras audio socket, as I didnt receive sound that way, myself. I pushed the red end on this into a electric 12 volt wall plug and plugged into the wall after doing as follows, I pushed the white audio socket on this into one of the ends, the white one of a 10 metre phono lead (bought from amazon) then put the audio receiving end of this outside my window next to my camera but not plugged into my cameras audio socket, and pluged the other end of the phono audio lead into the audio of my receiving audio of my video audio equipment which has the video of the camera already pushed in, which in my case is a mini dvr, my mini dvr only plays back sound during playback of recorded video files but that can be a usual occurrence with some dvrs. However this audio receiver does receive live sound if plugged into a video recorder, a dvd recorder, or a tv, with a scart adapter at the other end of the phono audio lead if the tv, video recorder, or dvd recorder requires one. Remember the video lead from the camera must also be plugged into one of the sockets of the same scart adapter the yellow socket. I usually use the red end of my 10 metre phono lead to extend my cameras video lead to my recording equipment plugging the red end of phono lead into the yellow socket on the scart adapter and white end into the white audio socket on the scart adapter. Av 3 source leads can be used but they are thicker. Great I now have very good clear sound for a security camera that had no sound at all via its audio socket plugged into the receiving audio source before. Phono leads can be bought in various sizes depending on how long you need them to be mine is 10 metres but they do 5 metres and 1.5 metres depending on how far your recording equipment is from the camera some cameras require male to male phono leads for extending them whilst others might require female to male phono leads check end leads of camera before buying.
