| Parameter | Description | Range |
| Device ID | This is the address of the connected device. This value corresponds to the value of the address switches in the connected device. | 1-255 |
| Device type | Selects the type of device used. | "Generic", "DD5-C", "Esprit ES30C/ES31C", "LRD41C21", "LRD41C22", "Spectra III", "Spectra IV", "Spectra Mini" |
| Parameter | Description | Range |
| Flip pan | If set to true, relative pan operations will be inverted | true, false |
| Flip tilt | If set to true, relative tilt operations will be inverted | true, false |
| Parameter | Description | Range |
| Back light compensation | Set to true to use the back light compensation. | true, false |
| Parameter | Description | Range |
| Move speed | Current maximum pan and tilt speed. | 1-100 |
| Pan move time per degree | Calibration constant for pan movements. Higher values give larger movements. When changing the "Move speed" (see above), re-calibration is required. Calibrate at currently used "Move speed", by adjusting the value until a 360 degree pan request (e.g. "rpan=360") pans (exactly) 360 degrees. If the pan speed is known, calculate this parameter value as 10000 * "seconds/degree". | 1-500000 |
| Pan scale compensation | Calibration constant to compensate for non linear pan speed values. A value of "0" will disable the compensation. Higher values will compensate with a higher pan speed and lower values will compensate with a lower pan speed. When changing the "Move speed" (see above), re-calibration is required. Calculate a pan request that will require only half the time of a tilt request (e.g. if the pan speed and the tilt speed in degrees/second is equal, "rpan=45&rtilt=90"). When sending this request, if the pan move is too small, increase this calibration constant, if the pan move is too big, reduce this calibration constant. | -100 - 100 |
| Tilt move time per degree | Calibration constant for tilt. Higher values give larger movements. When changing the "Move speed" (see above), re-calibration is required. Calibrate at currently used "Move speed", by adjusting the value until a 90 degree tilt request (e.g. "rtilt=90") tilts (exactly) 90 degrees. If the tilt speed is known, calculate this parameter value as 10000 * "seconds/degree". | 1-500000 |
| Tilt scale compensation | Calibration constant to compensate for non linear tilt speed values. A value of "0" will disable the compensation. Higher values will compensate with a higher tilt speed and lower values will compensate with a lower tilt speed. When changing the "Move speed" (see above), re-calibration is required. Calculate a tilt request that will require only half the time of a pan request (e.g. if the pan speed and the tilt speed in degrees/second is equal, "rpan=180&rtilt=90"). When sending this request, if the tilt move is too small, increase this calibration constant, if the tilt move is too big, reduce this calibration constant. | -100 - 100 |
| Zoom speed | Current zoom speed. NOTE: This value is mapped to 4 discrete speeds in the driver. | 1-100 |
| Zoom per unit | Calibration constant for zoom. Higher values give greater zoom changes. Calibrate at the most commonly used zoom speed, by confirming that a maximum zoom request performs a maximum zoom change. | 1-65535 |
| Focus speed | Current focus speed. NOTE: This value is mapped to 4 discrete speeds in the driver. | 1-100 |
| Focus per unit | Calibration constant for focus. Higher values give greater focus changes. Calibrate at the most commonly used focus speed, by confirming that a maximum focus request performs a maximum focus change. | 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 |
| Current field angle | Calibration constant for click-in-picture (center.) Higher values give larger movements. Calibrate at minimum zoom (i.e. zoom wide) and at the most commonly used speed, by making sure that clicking on an object brings the object to the center of the image. | 1-1800 |
| Pan bar range | Range (in degrees) to use with "panbar" requests. Clicking at the very end of a bar will pan half this value in the corresponding direction. | 1-720 |
| Tilt bar range | Range (in degrees) to use with "tiltbar" requests. Clicking at the very end of a bar will tilt half this value in the corresponding direction. | 1-720 |
| Send gap time | Minimum time gap in ms between sending two commands. Some "Pelco" devices require a time gap between commands. | 0-500 |
| Goto preset delay | Time (in seconds) it takes for the image to stabilize it self, after the camera has performed the longest "goto preset action". Used for disabling/enabling image analysis (e.g. motion detection). | 0-100 |
| Pelco protocol | What protocol to be used when communicating with the camera. | "Coaxitron" |
| Fixed pan tilt speed | If set to true, fixed pan and tilt speeds will be assumed. | true, false |
| Fixed zoom focus speed | If set to true, zoom and focus speed commands will be ignored. | true, false |
