Continuous Pan/Tilt/Zoom - Sony CH140 Application Manual

Application Guide

4.1.5. Continuous Pan/Tilt/Zoom

Notes:
• Full and Pan/Tilt users, as well as the administrator, can use this command.
• After the camera returns the HTTP response "204 No Content," send the next command.
If you do not wait for the response, wait for the target camera command transmission
interval time, which can be obtained using the "ContinuousPanTiltZoomInterval" inquiry
parameter, before sending the next command. (For a description of the inquiry parameter,
refer to the "4.2. Inquiry Command" section.) To stop the camera's PTZ operation,
immediately send "ContinuousPanTiltZoom=0,0,0" without waiting for the response to
the previous command. In environments other than the LAN environment, the moving
command and stopping command might be reversed, causing the camera not to stop.
In this case, wait for the HTTP response from the camera to ensure the order.
• Each time a command is sent, end and then restart the session. If you continue to send
commands without first disconnecting, the camera may respond less quickly to the pan, tilt
and zoom control.

You can specify a value in the pan direction in
one-step increments ranging from -100 to 100. The
actual moving velocity is 120 deg/sec with the zoom
position set to the wide-end when 100 is specifi ed as
the parameter. The actual velocity varies according
to the zoom position. When a positive value is
specifi ed, the camera pans to the right. When a
negative value is specifi ed, it pans to the left. When
0 is specifi ed, pan operation stops. If both pan
speed and tilt speed values are omitted, the current
pan/tilt operation is maintained.
You can specify a value in the tilt direction in
one-step increments ranging from -100 to 100. The
actual moving velocity is 60 deg/sec with the zoom
position set to the wide-end when 100 is specifi ed as
the parameter. The actual velocity varies according
to the zoom position. When a positive value is
specifi ed, the camera tilts upwards. When a
negative value is specifi ed, it tilts downwards.
When 0 is specifi ed, tilt operation stops. If both pan
speed and tilt speed values are omitted, the current
pan/tilt operation is maintained.
You can specify a value in one-step increments ranging
from -100 to 100. When a positive value is specifi ed,
the zoom moves in the tele direction. When a negative
value is specifi ed, it moves in the wide direction. When
0 is specifi ed, zoom operation stops. If input is omitted,
the current operation is maintained.
