I have never brought or seen any manufacturer that makes a 4 in one camera that can only change from TVI,CVI,AHD and CVBS via the OSD menu. Having that option for you guys that don't understand why ( no offence to anyone by that) is that i no longer need to run a beldon cable for rs 485 comms for data to the camera (this cable allows me to control the camera for zoom, focus,name of camera,privacy and all other sorts. Like the other gentleman said, you must have a button or a switch inside the camera or via the rg59 coaxial cable. In the old days you would need for one camera....................one rg59 coaxial cable, one power cable and the one cable for your data..... Now we can do it all via the RG59 coaxial cable which i think is absolutely amazing.
