How to set/query the camera name and location in C#

This example demonstrates how to set and query your IP camera name and location 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 set/query the camera name and location 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 set up 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: http://www.camera-sdk.com/p_13-download-camera-onvif.html
Windows forms version: C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\
Configure_Name_Location_WF\Configure_Name_Location_WF.sln
WPF version: C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\
Configure_Name_Location_WPF\Configure_Name_Location_WPF.sln

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

In addition to the methods discussed in the previous tutorials the additional methods of this example are the following:

IPCamera, created by using OZEKI Camera SDK is able to get notified when an attribute setting is completed, by subscribing to the AttributeSetCompleted event of the ipcamera object:

_camera.AttributesSetCompleted += _camera_AttributesSetCompleted;

When the event occurs, we are able to refresh this attributes:

_camera.RefreshAttributes(e.UpdatedProperties);

You can set the name and location of the camera by set the DeviceInformation property with new CustomInfo values:

_camera.SetAttributes(IPCameraAttributes.DeviceInformation, new[]   
            { 
                new CustomInfo("name", textBox_Name.Text)
            });

_camera.SetAttributes(IPCameraAttributes.DeviceInformation, new[]   
            { 
                new CustomInfo("location", textBox_Location.Text)
            });

After this, you are able to query the name and location of your camera or any other CustomInfo value by filtering the CustomInfo's properties:

var customInfos = _camera.CameraInfo.CustomInfos;
            foreach (var infos in customInfos)
            {
                if (infos.Name == "name")
                    label_Name.Text = infos.Value;
            }


var customInfos = _camera.CameraInfo.CustomInfos;
            foreach (var infos in customInfos)
            {
                if (infos.Name == "location")
                    label_Location.Text = infos.Value;
            }

Please note that none of the cancel and disconnect methods are included in the example because of the demonstrating intent and briefness of the article.

GUI

The Graphical User Interface of an application for setting/querying camera name and location in C#
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 the image of the IP camera device connected to your PC into the panel you can see on the picture. You can set the value of the textboxes responsible for storing the name and location by clicking to the "Set name" and "Set location" buttons. With the "Get name" and "Get Location" buttons, you are able to query the name and location of your camera into the labels you can see below.

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.

FAQ

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