I have been running two DCS-942L cameras for nearly a year, with direct login to the cameras over internet by direct IP login via fixed ports on my router. I did this daily from Europe for 4 months to monitor the cameras in my house in Australia. No problem, until I upgraded firmware to 1.22. Now, after a fresh power-up of both cameras, I lose direct video after a few hours, with all other functions working fine. I can see the video feeds via programs such as iSpy, but not when I log on via explicit IP address. This happens with two different computers, one running Windows 7, and the others XP, so it is a problem with some streaming application in the cameras themselves. Any suggestions?
