4 in 1 Cameras
4-in-1 cameras can be changed to Analog, TVI, CVI, and AHD. One camera has four different technology
Analog, TVI, CVI and AHD.
Most have a button on the cable like in the picture, hold for 5 seconds and move left/right/up/down to change. These cameras have BNC female and power input usually 12V DC.
Don't need to worry if the DVR supports the camera; change to desired option with the flip of a button on the camera cable, no tools needed. Even better if you DVR is Analog it will work now as Analog camera. When you purchase an AHD, HD-TVI or HD-CVI just change the mode to HD.
