8.4 ContinuousPanTiltZoom parameter (syntax: ContinuousPanTiltZoom=<pan
speed>,<tilt speed>,<zoom speed>)
This parameter is suitable for the pan and tilt operation which a joy sticks was used for.
About <pan speed> setting:
This value can be specified with one step within the range from -100 to 100. It moves to the right side
when a positive value is specified, and when a negative value is specified, it moves to the left side. Pan
operation stops when 0 is specified. The speed is almost directly proportional according to the value.
Actual speed changes according to the zoom position. When the value is 100 on the Wide edge, speed
becomes 120 degree/sec. When this value and <tilt speed> are omitted at the same time, present
operation is maintained about pan and tilt operation.
About <tilt speed> setting:
This value can be specified with one step within the range from -100 to 100. It moves to the upper side
when a positive value is specified, and when a negative value is specified, it moves to the lower side. Tilt
operation stops when 0 is specified. The speed is almost directly proportional according to the value.
Actual speed changes according to the zoom position. When the value is 100 on the Wide edge, speed
becomes 60 degree/sec. When this value and <pan speed> are omitted at the same time, present
operation is maintained about pan and tilt operation.
About <zoom speed> setting:
This value can be specified with one step within the range from -100 to 100. It moves to the Tele
direction when a positive value is specified, and when a negative value is specified, it moves to the Wide
direction. Zoom operation stops when 0 is specified. When this value is omitted at the same time,
present operation is maintained.
About parameter sending interval:
You should send the next command after waiting for HTTP response "204 No Content" from the camera.
When you do not wait for the response, you should send the next command after it waits at the time of
the value of "ContinuousPanTiltZoomInterval" obtained by using system information inquiry
"/command/inquiry.cgi&inq=system". The unit of "ContinuousPanTiltZoomInterval" is ms. Send
"ContinuousPanTiltZoom=0,0,0" at once regardless of the above-mentioned when you stop PTZ
operation of camera. Except for LAN environment, moving command and stopping command might be
reversed, and the camera doesn't stop. In this case, wait for the HTTP response from the camera to
guarantee order.
About Connection:
When using "ContinuousPanTiltZoom" parameter, reconnect every time the command is sent. The
reaction of the PTZ operation worsens if keeping connection.
