I got a single channel Winfast Tuner card. When i hook up the quad to it all the channels have lots of noise. While hooked up to the TV they work fine. They are all wireless cameras.

Also i noticed when i push the QUAD button to have all 4 up the quad seems to act funny and all the pictures are very fuzzy or barely seeable.

Is it because i am using wireless ?

The receivers are on the other side of the room. I also tried to bring them outside

Any analogue to digital conversion has some degree of loss. In this case you're looking at a few things. One is a weak camera signal. Second may be the card. I don't know that card so I can't help you troubleshoot it.
