How to adjust Pan, Tilt and Zoom speed in C#

In this guide you can find information on how to adjust pan, tilt and zoom speed of your camera with your Windows Forms/WPF Application written in C#. To implement this example, you need to have Ozeki Camera SDK installed, and a reference to OzekiSDK.dll should be added to your Visual Studio project.

How to adjust Pan, Tilt and Zoom speed using C#?

To implement Pan-Tilt-Zoom control you should apply the same code snippet you have used in the How to implement Pan-Tilt-Zoom (PTZ) control example. Important: you should study this article in order to find out how to setup your Windows Forms/WPF Application correctly.

Getting started

To get started it is recomended to Download and Install the latest version of Ozeki Camera SDK. After installation you can find the example code discussed in this page with full source code in the following location on your harddisk:

Download Ozeki Camera SDK:	https://www.camera-sdk.com/p_6513-download-onvif-ozeki-camera-sdk-for-c-sharp.html
Windows forms version:	C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\ PTZ_Speed_WF\PTZ_Speed_WF.sln
WPF version:	C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\ PTZ_Speed_WPF\PTZ_Speed_WPF.sln

To compile this example you will need Microsoft Visual Studio installed on your computer.

The additional statements and methods of this example are the following:

Whenever you press a PTZ button, you should adjust pan, tilt and zoom speed in the Move() method by the query values of three trackbars:

_camera.CameraMovement.PanSpeed = (float)trackBar_Pan.Value/100;
_camera.CameraMovement.TiltSpeed = (float)trackBar_Tilt.Value/100;
_camera.CameraMovement.ZoomSpeed = (float)trackBar_Zoom.Value/100;

Note: pan, tilt and zoom speed is a float value ranging between 0 and 1, so we'll have to divide the values of the trackbars by 100.

In addition, you can display the trackbars's value on the GUI labels to inform the user by the trackbars scroll event.

GUI

the gui of your app — Figure 1 - The graphical user interface of your application

After the successful implementation of the functions and the GUI elements, the application will work properly. Pressing the connect button will load in the image of the IP camera device, connected to your PC, into the panel that you can see on the picture.

Below you can find the code that belongs to the interface of the previously presented application. With the help of this section your Windows Forms Application will be able to work properly.
