Can anyone explain to a newbie in the cctv field the qualities of leads etc foe me please ? i have been using pcb board camera that i find are low profile and with the right lens cover all the areas i need for my home,some ive got also capable of 940nm but a lead was broken and when i opened the lead up it was a very cheap and nasty job that came with the camera,i read that lead are supposed to be shielded but this was just a shared negative earth lead twisted in a very crude fashion round the video lead, i have tried to repair it but the picture is very dark now,much darker than it used to be and i dont know where to get these small connector leads,what did i do? can someone explain about leads and if shielding makes any difference please ?

it was from a system taken out before demolition of a building by a friend who knows i use cctv and have a pcb camera but its not the same.it just came with diagram of the 4 pin and what the assigned pin are 1 v+, 2v-, 3vid+, 4vid-. on my other pcb camera i just plug it in with 3 pin connectr and then to cctv lead.with 4 pins im not sure just dont want damage it

the cctv dvr i am using needs to use Internet Explorer to view it over the internet is there a dvr i can get that doesnt need to use this as i find it so slow loading and don`t like IE anyway ? i just want a dvr that i`m not tied down with when viewing on the web

from how i understand this it means the v+ and v- from the power connector to pins 1 and 2 and the video+ (pin 3) and video-(pin 4) connected to the bnc ? do i need to unite the earths ? i am using this in a cctv dvr
