[VF-101G-KIT/VF-102G-KIT/VF-106G-KIT] Why did the monitor connected to HDVR display show black and white video?

The VF-10xG-KIT supports AHD/TVI/CVI/CVBS video. Please make sure your camera is set as AHD/TVI/CVI/CVBS mode and adjust the HDVR to a corresponding mode. For example, set the camera and HDVR as an AHD mode.
