Overview

This VI allows a user to take in the images being broadcasted by an Axis camera.

Description

IP Cameras are a type of digital video camera that send and receive data via a computer network. One of the ways to access these cameras is to use a Web Browser and simply type the IP of the camera into the Web Address bar.

This particular VI mimics this procedure by embedding a web browser into the front panel. It uses an Event Structure to capture when the user clicks the Load Browser button and loads the URL into the browser via the IWebBrowser2 Property Node.

Steps to Implement or Execute Code

  1. Type in the camera's IP address
  2. Run the VI
  3. Click the Load button

Requirements

Software

LabVIEW 8.6 "or compatible"

Vision Acquisition Software 8.6 "or compatible"

The VI worked great.

How would I do image analysis on the web stream I am getting with NI's vision tools.

Tried downloading and running. The first error, the system could not find the 'TitleChangeCallback.vi'. 2nd error, could not find the 'BeforeNavigate2Callback.vi'. I guess, where would I find these guys?

Simple fix. Remove the callback and just have the IP camera load to a webpage. Loaded the new code and it should be working.

The video feeds that I am getting are very large with a "splash" around them. I would really like to be able to trim the splash off and shrink the image. Any ideas?
