Answer 1

If you have wireless?
----------------------------
Then it is possible that either the camera is too far away from the receiver or

a) there is radio interference, so move camera around to see if this solves the problem or
b) there are other wirless cameras in the area. If you have too many wireless devices in one area, then the frequency is crowded. If the camera have channel selctor, try changing the channel


If you have wired cameras
------------------------------------
The are several possible problems.

a) If the cable is near electrical line, then move cable
b) check to make sure cable is not damaged
c) make sure the power supply is enough,
d) make sure the camera is not more than 30 meters away, as power is lost the longer the cable
e) try a 'hum bar' or 'ground loop isolator'. this can remove interferrence cause by double grounding. This device removes the grey bar moving up & down the screen

Answer 2

If this is wireless, it might be picking up another signal. Try changing the channels or frequency if possible. Of bring the camera closer to see if it's weak signal.

If it's wired, this would sound like a defective cable. Try the the camera on a different cable up close. This will test to see if it's a particular cable.

And remember, maybe it's just bad!
