How to take a picture snapshot and save it as .jpg in C#

In this guide you can find information on how to connect to an IP camera with your Windows Forms/WPF Application written in C# and take a snapshot in JPG file format. 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 take a picture snapshot using C#?

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 additional statements and methods of this example are the following:

button_SaveTo_Click(): makes the user be able to choose the path and saves the result into the TextBox GUI element that can be seen on the picture below.

Btn_Snapshot_Click(): initializes the path variable that is used to determine the destination folder of the captured picture. Then calls the CreateSnapShot() method with this parameter.

_connector.Connect(_camera.VideoChannel, _snapshotHandler): you need to connect the video channel of your camera to the snapshot handler.

CreateSnapShot(): creates a string that contains the actual date and time then uses its parameter to complete the path. Finally, takes a snapshot of the actual picture of the IP camera and saves it into the destination folder:

If the TextBox GUI element is empty, there will not be a path where we could save the captured video then we have to save it to the source folder where the application has been started.

  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 OzekiSDK.dll to the references of the solution.
    • Please import the missing classes.
