speed dome IP camera reverting back to preset position and not recording

I recently purchased a speed dome IP camera (DS-2DE52201-AE) that continuously reverts back to preset focus position whenever i focus it in a specific direction. I have tried creating a tracking pattern but if there is a power outage or interruption, it reboots and goes to the preset position. moreover i have 16 cameras on my 9600 series NVR and just that specific camera has no recorded feed on it.

how do i rectify?
