Camera has no video
From EZWatch Wiki
No video from analog security camera
If you have connected an analog security camera to your recording system but you do not get any video from the camera, there are multiple possibilities and tests that can be run to narrow down the cause to one specific source.
Step 1 - If the camera is connected to a recorder with multiple ports (Such as an EZ Watch Pro v3.1 or v4.0 PC-DVR, or an ArmorPro Hardware DVR) try plugging the camera into a different port on the unit. If the image comes up, then there may possibly be a bad port on your DVR.
If you are plugging the camera into a DVR which only has a single port, it is recommended that you try connecting the camera to a television. To do so, simply place an RCA to BNC adapter on the end of the camera cable, and plug it into a yellow video in port on your TV. Turn the TV on to the video input you connected it to (Input 1 may be 'VCR1', 'AUX1', 'Video 1'or 'Input 1' on your TV. Check your TV manual if you're not certain how to access your TV's input) and you should see an image from your video camera.
RCA to BNC adapters can be purchased at many electronic stores, or you can purchase it directly from EZ Watch Pro.
Step 2 - If you have determined that the camera does not work on any port or by connecting it to a TV, try plugging in a different power supply to that camera. If the power supply was hit by a surge of electricity or if it overheated, it may have shut off and no longer be providing power to the camera. If you have a multimeter available, try testing the end of the power supply and the end of the cable to determine if the power supply is transmitting a full 12V of power. If the unit is transmitting too little power, your camera may not function.
Step 3 - If you have ruled out that the power supply is the culprit, then you will want to eliminate the cable as a possible cause of the issue. Since the cable has most likely already been run and installed replacing the cable may be too difficult, so it is instead recommended that you try removing the camera, moving it to the position of a different camera, and swapping the two. If the camera starts working on another length of cable, and the other camera has stopped working, then your cable is the most likely culprit. It is recommended that you replace the cable.
If you have only a single camera, try bypassing the cable entirely and plugging the camera directly into the back of the DVR/TV. You can use a BNC Male to Male Barrel Connector to connect the camera directly to the DVR without needing the cable.
Step 4 - If you have tried a different cable, a different power supply, and a different port on your recorder, but the camera still does not work then it is likely that something has caused the camera to fail.
