Hello, im working in store, and sometimes we need to check cameras but we can only access few cameras, and its only work in old internet explorer, something called nvr3.0, first we open ie then type ip address and its asking username and password, then its gonna show few camera. But before there was guy who can access all the camera. I dont know he used ie or nvr enterprise software, i tried to use that software but dont know server name, ip, port. So other cameras using different username password? Or its ip address different? I know about tech stuffs but dont know much about networking or ip stuff. So how can i access other cameras and how to use nvr software u think its better than ie, atleast i can save some playbacks.
