did you try both ports 8856 and 5856 for icamview and Shixin cameras in the PTZ tab?
It is also possible that the user name and password are wrong, or the account doesn't have PTZ operation privileges.
Email support and see if he can help you...your issue is common when using obscure cameras....i have already try all this and nothing Works.
