This worked perfectly with my Hilook (Hikvision) PTZ camera.
I used the setting from Nicovdd above as the Command
curl --anyauth --user admin:Password -X PUT
http://192.168.1.64/ISAPI/PTZCtrl/channels/1/presets/SCENE_VALUE/goto
Then set the scene value to the preset number.
I had to setup the presets via the web interface for the camera. Used the Internet Explorer addon for Chrome.
