The root reason

Old cloud certificate expires in April 12 2016, and new certificate uses device time as access, in the other word, only device time after April 12 2016 can access to our new cloud service.



How to solve the problem

Go into management interface first. If you don’t know, how please click:

How to log in to the cloud camera’s Web Interface?

 In System>>Date/Time>>Automatic Time, please choose Synchronize with NTP Server, and the camera will get the right time automatically.


Note: We don’t recommend you to choose Set Date and Time Manually, or your camera will reset the time to 2008/01/01 every time you unplug and plugin the power supplier, which means you won’t connect to our cloud server once you do that.
