Dip switches settings
|
| S1, S2: |
The setting of S1, S2 rotary dip switches
corresponds to Identity
(in hexadecimal

unit.
The switch S1 is blue and the switch S2 is
yellow. |
| LK1: |
This is
a small jumper located beside the yellow rotary dip
switch S2 (see above). Select termination of the
RS485 bus with this jumper.
For the last unit,
set this jumper = ON.
For other units, set this
jumper = OFF (remove the jumper). |

Movement,
Move Speed: |
The
Speed used when one of the 8-arrow buttons are clicked
and when the CGI commands "rpan" and "rtilt" are
used. |
Movement,
Move Time: |
This value is the time it takes for the dome
to move one degree at the speed given above. Used when
one of the 8-arrow buttons are clicked and when the CGI
commands "rpan" and "rtilt" are used. |
Movement,
Picture Speed: |
This is
the maximum speed used with click-in-picture movement.
This speed depends on the distance from the center of
the image - the further away from the center the higher
the speed becomes, and reaches its maximum value at the
edge of the picture. |
Movement,
Picture Time: |
This is the time between the start and the
stop commands for a click-in-picture movement. This time
is independent of where in the picture you click. |
| Zoom,
Speed: |
The
speed used for zoom movements. |
| Zoom, Time: |
The maximum time for a zoom move, used when
you click the ends of the relative zoom bar. If you
click closer to the center the time will be scaled to
reflect this, i.e the further from the center you click,
the longer the time used. This also affects the "rzoom"
cgi-command. |
| Focus,
Speed: |
The
speed used for focus movements. |
| Focus, Time: |
The maximum time for a focus move, used when
you click the ends of the relative focus bar. If you
click closer to the center, the time will be scaled to
reflect this. i.e the further from the center you click,
the longer the time used. This also affects the "rfocus"
cgi-command. |
| Digital zoom: |
To enable
or disable digital zoom, use one of the commands from the table below
in the CGI-request:
"http://<server name>/axis-cgi/com/ptz.cgi?camera=<cam
nbr>&auxiliary=<command>".
| extend-on |
Enable digital zoom. |
| extend-off |
Disable digital zoom. |
| extend-toggle |
Toggle enable/disable of digital
zoom. |
