The strange thing is that when i ping the camera at the 192.168.1.108 i take some ping replies for some seconds. For this seconds i could telnet the cam but the cam restarts and the telnet loses connection. I dont know if there is a special cable for connecting the cam to pc via a rs232(pc) and ethernet(cam) and run tftp like software.... Inside the cam i had also a 4 pin connector like this in your photo but i cant understand what it is...
