How to get detailed camera information and capabilities in C#

This example demonstrates a simple method for how you can get detailed camera information and capabilities of your camera 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 get detailed camera information and capabilities using C#?

To establish the connection properly between your application and an IP camera you should apply the same code snippet 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:	https://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\ Configure_Camera_Information_WF\Configure_Camera_Information_WF.sln
WPF version:	C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\ Configure_Camera_Information_WPF\Configure_Camera_Information_WPF.sln

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

The additional methods of this example are the following:

Subscribing to the CameraStateChanged event of the camera object:

_camera.CameraStateChanged += _camera_CameraStateChanged;

When the ''Streaming'' event occurs, you can inform the user by writing the information and the capabilities of the camera to the label:

textBox_Info.Text = GetDeviceInfo();

In the GetDeviceInfo() method you can get information and capabilities of your camera by getting the _camera object's properties.

GUI

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. After you have connected to an onvif camera successfully, you can see information and capabilities of your camera.

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.

DISCLAIMER: Please note that the following features will only work if your IP camera supports the given function. You should check the user manual of your IP camera to make sure it supports the feature that you wish to implement in C#.

FAQ

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

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.)
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 the OzekiSDK.dll to the references of the solution.
- Please import the missing classes.
Can I get more queryable information about the camera?

Yes. For example at the _camera.NetworkSettings you can get information about network settings
of the camera like DHCP, DNS, HostName, HttpPort, HttpsPort, IpAdress, MacAddress etc.
For more queryable properties please see under the IPCamera class definition.
