Please post your system info.
1. Type Camera?
2. Type wireless receiver single or multi channel and # of outputs?
3. Type DVR?
4. Did you buy it or build it?
5. How is it all tied together?
With the above info we can see the system and not guess at answers.

Hi,
1. camera wite CCD sensor, i checked a few cameras.
2. I used 3 independes recivers + transmiters 1.2 Ghz, the chanells are diferents.
3. the DVR card is GV-800 of GEOVISION.
4. i didnt bild it myself, i buy it from en engineer that fix between the transmiters and the JMK recivers.
5. the cam connected to the transmiter, the reciver connecting to the input of the DVR card.
I want to remind you that it works every set but together i get VIDEO LOST or the pic stuck,
i dont know what to do!
thanks,

It sounds like you have interferance from your wireless.
1. If you can with without to much trouble move the camera's to the dvr and see if they will work hardwired. If that works try adding the wireless one at a time and see where it quits working. You also might try seprating the receivers 4 to 5 feet apart, receivers have rf ossilators and they will transmitt a signal and could be the problem.
2. If it does not work hardwired let us know it might be a video setting. Also what are the pc specs. motherboard cpu video card and settings if you know.
