Dahua PDN22T204GN not functioning as intended

[PTZoom_Zoom]

I have a customer with an older PTZ cam that is randomly moving the camera to the edge of it's axis and then just sitting there and then will not respond for a period of time.

I took the camera back to my shop, hooked it up to my network and factory reset it. I am still getting random dropouts when I cannot see it nor power it. I have to reconnect to the web interface in order to control it again. It was also constantly losing it's date and time thought not doing that anymore.

Anything else I can do or should I just advise my customer to purchase a new one based on this cameras age?

Thanks in advance for any suggestions.

How did you power the PTZ ?

POE switch.

does it have a 'cmos' battery on one of the circuit boards?

How old are they? Do they go by any other model number on their labels or web interface?
