Hi! I have a conceptronic cctv kit and we want to set it up. I have tried to connect from server port, http port and the handset port (7777. 80. 580) opened 80 and 7777 in the router's settings. There is also a "Software update" button, but it needs a USB drive with the file on it to update, there are no update files found on the internet, but can I replace it with some other software by that button? Please I am desperate.
