I have an NC450 camera for a few years, but recently I noticed that it restarts every 2 minutes or so, in this case the light turns green and after a few minutes the light automatically flashes red (it disconnects and restarts). This only happens when it is connected to the ethernet or wifi network, if there is no internet this does not happen. I tried changing the charger/power supply, I also used Wi-Fi, I also used another ethernet cable, but the behavior remains the same. It currently uses software version 1.5.6 and version hardware v2, I tried to downgrade, but when I put the camera's ip in the browser, it does not open the camera's configuration web. (I also restarted it, and the same thing happens)
