|
Assigning camera address and "Device ID".
|
A camera address must already be assigned to a Cohu PTZ device before using it with this driver (the Cohu PTZ device have no DIP-switches for assigning camera addresses).
|
|
"Joystick" navigation and "continuouspantiltmove".
|
The "Joystick" navigation mode and the "continuouspantiltmove" command are not supported (tilt motor may be stalled when reaching the lower tilt position limit).
|
|
Manual focus and zoom move.
|
A zoom move will set autofocus=on. After a zoom move, a short delay is required before a manual focus move is possible.
|
|
Presets saved in the Cohu PTZ unit and digital zoom.
|
When saving a preset in the Cohu PTZ unit (device presets), the digital zoom position is not saved (e.g. device presets are only saved in optical zoom area).
|
|
Preset positions.
|
When saving a preset position, only pan, tilt and zoom positions are saved in the preset.

The optical data limits are used to tune image centering:
- Zoom out completely and adjust Max Field Angle until the spot you click becomes centered accurately.
- Zoom in completely and repeat for Min Field Angle.

| Parameter |
Description |
Range |
| Focus time |
The calibration constant for focus (time in ms for maximum focus change). Higher values give greater focus changes. Calibrate by confirming that a maximum focus request (i.e. "rfocus=9999") at one extreme (e.g. focus near) takes you to the other. |
1-65535 |
| Iris time |
Calibration constant for iris (time in ms for maximum iris change). Higher values give greater iris changes. Calibrate by confirming that a maximum iris request (e.g. "riris=9999") at one extreme (e.g. full iris close) takes you to the other. |
1-65535 |
| Goto preset delay |
Time (in seconds) it takes for the image to stabilize it self, after the camera has performed the longest "goto device preset action". Used for disabling/enabling image analysis (e.g. motion detection). Note that this does not apply for server presets. |
