4in1 security camera's (BNC)

XVR cameras are also known as 4-in-1 cameras: these cameras have both analog signal and AHD, CVI and TVI signal.
As a user, you can then choose which signal you want to use, so that you can also use the camera in combination with newer AHD, CVI or TVI recorders.
Conversely, there are also XVR recorders that are compatible with all the aforementioned signals.
There are also tribrid cameras (3-in1: analog, HD-TVI and IP) and Pentabrid cameras (5-in-1: analog, AHD, TVI, CVI and IP).
