How to configure IP PTZ
In order to use IP PTZ, a camera has to be added as Web Video / IPPtzCamera.
The configuration form contains the option IP PTZ
AbelCam works with coordinates +-100 for both pan and tilt. IP PTZ Cameras use all kind of values and ways to set them. The IP PTZ configuration maps the cameras coordinates to the AbelCam coordinates.
Camera Type
First configure the camera type you are using
AbelCam supports three types of IP PTZ cameras. They all have in common a web interface which allows to control PTZ moves.
- PTZ Read Write
these devices allow to set and read PTZ parameters. Those parameters can either be absolute (in relation to the whole PTZ range) or relative ( to the current PTZ position) - PTZ Write only
While PTZ values can be set, these devices do not reveal the current PTZ position. Positioning is possible either absolute or relative to current position. - PTZ Write Steps
This camera type can only be moved stepwise.
Preconfigured types
the preconfigured types can be used to get started with IP PTZ and be adjusted if required.
Calibrate
Calibrate is required only for cameras with relative positioning.
Control Configuration
Range
Configure the pan, tilt and zoom range in camera units
Set
For bot Get and Set operations, use the templates #PVALUE, #TVALUE, #ZVALUE for the cameras pan, tilt and zoom values
- Initialize Camera
insert up to two URLs which will be called before starting PTZ operations - Move Home
Use this URL to configure the home position - Set
this URL controls the PTZ position
Get
URL and template to retrieve the current PTZ position
Timers
- Keep Alive Interval
some cameras want to move to their home position. If this interval is > 0, every x seconds the position will be set to the current position in order nail the camera to that position - Wait Factor for Pan moves
required for PTZ write only cameras. The wait factor prevents camera move commands while camera is still moving. 2 is a good value for fast cameras, use 10 for slow ones. - Wait Factor for Tilt moves
Same as above for Tilt moves
Pan | Tilt | Zoom
- URL to set value
use these URLs when Pan/Tilt/Zoom cannot be set with one URL in Control Configuration / Set - URL to get values
use these URLs when Pan/Tilt/Zoom cannot be set with one URL in Control Configuration / Get
