In this article, i'm going to explain about how to integrate a webcam into your web application using ASP.NET 4.5.1. A web camera can capture images at the server end and a web page can display them. It’s very simple for integrate a webcam and capture images in your website that using ASP.NET 4.5.1.

Before it, make sure that your device has Latest Flash player and Web camera.
Let's following these steps:

First, copy the “WebcamResources” into your new application.
After that, add the following code in to your Default.aspx page:
<object width="450" height="200"param name="movie1" value="WebcamResources/save_picture.swf"

embed src="WebcamResources/save_picture.swf" width="45
height="200" >

This code will place your Flash object into your web page, used to capture the images from the web cam.
Add one more page there with the name ImageConversions.aspx.
Add the following code into ImageConversion.aspx at the page load event:
string str_Photo = Request.Form["image_Data"]; //Get the image from flash file
byte[] photo = Convert.FromBase64String(str_Photo);
FileStream f_s = new FileStream("C:\\capture.jpg", FileMode.OpenOrCreate, FileAccess.Write);
BinaryWriter b_r = new BinaryWriter(f_s);

The above code will convert the bytes to an image and will save the image in the c drive.
