The following picture is the connection setting in v. 0.9. So I select similar option which is "IP Camera" in V. 1.5.
In V. 1.5, I selected "IP Camera" as camera model, and then input IP, Port, user, password. Testing connection is OK.
PTZ work in v. 0.9 but don't know if it works in V1.5.
Please send me a PM.
