<h2>How to configure IP PTZ</h2>

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.

<h2>Camera Type</h2>

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<br>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<br>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<br>This camera type can only be moved stepwise. 

Preconfigured types

the <a href="#Examples">preconfigured types</a> can be used to get started with IP PTZ and be adjusted if required.

<h2>Calibrate</H2>

Calibrate is required only for cameras with relative positioning.

<h2>Control Configuration</h2>
<h3>Range</h3>

"Range":img:/img/316/ipptzrange.png

Configure the pan, tilt and zoom range in camera units

<h3>Set</h3>

For bot Get and Set operations, use the templates <b>#PVALUE, #TVALUE, #ZVALUE</b> for the cameras pan, tilt and zoom values

"Set":img:/img/316/ipptzset.png

- Initialize Camera<br>insert up to two !URLs which will be called before starting PTZ operations

- Move Home<br>Use this URL to configure the home position

- Set<br>this URL controls the PTZ position


<h3>Get</h3>

"Get":img:/img/316/ipptzget.png

URL and template to retrieve the current PTZ position

<h3>Timers</h3>

 - Keep Alive Interval<br>some cameras want to move to their home postion. 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<br>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 Factore for Tilt moves<br>Same as above for Tilt moves

<h2>Pan | Tilt | Zoom</h2>

- URL to set value<br>use these !URLs when Pan/Tilt/Zoom cannot be set with one URL in Control Configuration / Set

- URL to get values<br>use these !URLs when Pan/Tilt/Zoom cannot be set with one URL in Control Configuration / Get
