I have been through 4 of these now and have experienced a 50% problem rate. The first one I had kept disconnecting from any of the web based viewing apps every day. I could not see it anywhere except for the computer that was on the same network as it. I wood have to keep disconnecting the power to reboot it so I could see it again. I contacted Dlink support and their solution was to replace it. BUT, apparently there was a firmware update available that might have fixed the problem. Dlink reps did not say anything about an update that was available for it. And when I went to the support page- http://support.dlink.com/ProductInfo.aspx?m=DCS-6010L, it still does not show the firmware update. However if you go to a different support page- https://www.mydlink.com/download, it shows at least 2 new firmwares. If I had been told this I might have been spared the expense of shipping this back to Dlink from overseas.
Now I have another one of these cameras with similar problems but worse. Green tint to the picture, and requires occasional rebooting because it just quits. But I am afraid to apply the new firmware because of so many complaints. One day I will have to take my blood pressure medication and try it.
I do have 2 of these cameras that seem to be fine.
