Where to install the isolator, direct to the DVR or to the CCTV camera...I guess Equipment means the Camera and Cable is the DVR?

why redirect from this forum to your own

and then your fix on your forum is the biggest load of crap

 

some of your quotes ......

 

CAUSE: Another thing you can do to find out the cause of the security camera image flickering is to disconnect the coax at the camera output. Check if the flickering still continues.

 

Or

 

 1.CAUSE: The first thing that you will need to check is whether the video input to the monitor a loop through with a video output to drive for example video tape recorder.

 

video tape recorder  ????  Your 20 years behind  

 

 

 

And you want people to pay you with PayPal 

Reading your forum is like reading a joke book
