How to implement automatic movement (left and right scan between two points) for an IP camera at different speeds in C#

This example demonstrates how to implement automatic scan function into your PTZ camera application with motion control using C# language. With these features your application will be able to pan the environment automatically between two points, in left and right directions. 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.

Using the SDK's motion control features

To establish the connection properly between your application and an IP camera you should apply the same code snippet what you have used in the example (How to connect to an IP camera device using C#?). 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:
Windows forms version: C:\Program Files\Ozeki\Ozeki SDK\\Examples\Other\
WPF version: C:\Program Files\Ozeki\Ozeki SDK\\Examples\Other\

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

The following methods can be used to scan automatically wtih your PTZ camera.

  • _camera.CameraMovement.Patrol(patrol, duration);
  • _camera.CameraMovement.StopMovement();

These two methods provide the function to start and stop automatic movement at different patrolling durations.

_camera.CameraMovement.Patrol can start scan with these given parameters:

  • patrol: ToRight, ToLeft, ToUp, ToDown
  • duration: double value

Automatic control

The following lines will show you a possible way to make your application to be able to scan automatically. With the presented method the camera can pan the area between two fix points. With the code below you can set the direction of the scan and start the automatic process that will operate the camera. Beside the described function you can also set how much time the camera should spend between the sides of the scanned area. Here is the code you can use to add these features.

Below you can find the answers for the most frequently asked questions related to this topic:

  1. How can I get the URL of the camera?

    You can get the URL from the producer of the camera. (In the 10th tutorial you can find information on how to create an own IP camera discoverer program.)

  2. I have not managed to build the solution. How to solve it?

    • Please set the Target framework property of the project to .NET 4.0.
    • You should add the System.Drawing.dll and OzekiSDK.dll to the references of the solution.
    • Please import the missing classes.
  3. Why is the camera scanning, when I didn't order it?

    It is possible that someone else is also using the camera.
