Ok this is what I did to overcome the binding issue
The plate on the camera is ok the problem is when yo screw it to the bracket
The dimples in the bracket seem to kick out the alignment
As when I first screwed mine on after hooking it up on the bench I tested it in the bracket and it made all sorts of noise and seemed it couldn't get to where it was supposed too in its start up sequence
So I took it off tested it without the bracket and it was perfect
So I then glued 4 washers to the ptz bracket and sprayed some silicone spray on the camera silver bracket and twisted the camera on,then tested the camera hanging as it would off the wall and it made no noise and did its check sum
That really fixed my problem I did make a lead up as I have audio and power and cat cable going thro mine and ran them to a junction box as fitting all those wires in the bracket seemed painfully hard
this does not fix the issue for me, as soon as the PTZ need to go behind i.e. down to floor and spin around and go back up, it just locks up as soon as it hits the down position. I have tried contacting AliExpress merchant, but they are now ignoring my communication, I so I have a Credit Card claim in with bank. the PTZ is defiantly faulty Imo, as I have another from a UK official retailer and that is working perfect, same cable, same mount, same everything, IMO they must be a dodgy batch going around, UK Hikvsion had never herd of the issue and ask me to return the camera to where I purchased it from. so lesson learned only buy from official retailers from now on.
