The cause for a double image could be as simple as a loose BNC connection at the DVR or the camera, to a defective video monitor or security camera.

First try moving the connector back and forth while watching the video on the monitor, if you see the image clear up then you know that it is the connector.

If that doesn’t work next thing I would do is to power down and reboot the camera. This might solve the problem, but even if it does it might mean the camera is reaching towards the end of its life and will probably have the same problem again. 

If that still doesn't work, please contact support, provide a photo of the camera lens, a screenshot of the LiveView page, and the purchase invoice.
