I'm having trouble syncing the camera with my hub.
In order for the Sync operation to complete you should first ensure that the camera and hub are both on. For the hub this occurs automatically as soon as the power cable is connected and turned on at the socket so be sure to do this after connecting the hub to your router first. To power on the camera press and hold the button on top of the camera for five seconds. The camera led will flash green.
Once powered on press and hold down the button on the hub for 1 to 2 seconds then repeat with the button on the camera making sure to only press for 1 or 2 seconds, any longer and you may inadvertently turn the camera off again.
If the camera does not sync to the hub try moving the camera closer to the hub, it may be that the camera cannot connect over wireless. When performing the sync operation it is important that the two hub and camera units be as close as possible, with line of sight of each other.
