A project I want to do is write a Labview application that would communicate to the Webcam USB and publication of the application in a secure web page, and allowing users to control Labview applications at home, work, and anywhere in the world without having installed on the PC of the Labview software. On the web, users can control the Labview front panel for zoom, annotations, etc. As a surveillance camera the USB Webcam will be detect an object moving, save images when motion was detected, an alarm to alert.

I was wondering if anyone can help me with this.

I have Labview Vision and I can get the USB Webcam streaming images.

I don't know where to find information about the detection of a moving object.

Can someone help me on this please?

Hi krispiekream!

I guess that your USB camera has the ability to zoom through a control programmatically? If not you should be able to control the camera using a remote facades, which require the LabVIEW runtime engine. Here's a tutorial on the remote Front Panel LV development of Applications: http://zone.ni.com/devzone/cda/tut/p/id/3277.

With respect to the detection of a moving object, you can take two images and subtract to determine if there was movement in the frame.

I hope this helps!

  • Can I use the CD that came with my Palm Z22 to install on my new computer Windows 8 2005?

    I'm upgrading from a Dell XP machine on a computer Dell Windows 8.  My old Palm Z22 driver installation CD will work to load the software into my new Windows 8 machine; or do I need to download a new software specifically for Windows 8?

    After losing almost three frustrating weekends, I finally got my Z22 to synchronize with Windows 8.  You never answered my first question [can I use the CD that came with my Palm Z22 to install on my new computer Windows 8 2005?], that would have eliminated a lot of uncertainty in my many attempts to synchronize with the download of version 6.2 has recommended you.  Fortunately, I wasn't the original CD with version 4.2, because 6.2 has toured with a bit more clear instructions and a new download of http://www.palmdr.com/windows-7-64-bit-usb-drivers

    Original title: built in webcam 1.3

    Hi, Nancy,.

    Control Panel > add a device

    Windows will search for devices connected to your system, but not installed. Click on the name of the webcam which shows in the search box and then click "next".

    Choose whether you want Windows to search for the device driver webcam using Windows Update on the Internet, or if you prefer research of Device Manager to the driver using a disc provided by the manufacturer of your laptop. Most of the drivers are on the system recovery disk included with your laptop, if you choose to add the driver from the disk. Check the box of your choice, then click on "next >" to continue.

    Wait while Windows searches from the driver using Windows Update, if that is your choice. There's an active Internet connection for Windows to do successfully. Allow the computer to install the driver and then restart the system for the webcam to be recognized by the system.

    Otherwise, you can use the system recovery disk or a driver downloaded directly from the manufacturer of your laptop to install the driver without using search Windows Update.

    Open the CD/DVD-ROM drive and insert the disc of recovery system or place the driver downloaded from the manufacturer in a directory of files easily accessible on your PC, or on the desktop, or in your 'My Documents' folder.

    Choose the option 'install the software automatically (recommended)' into the application 'Add a device', then press on "Next >" to start looking for your webcam driver. The Hardware Wizard will search the system recovery disk and automatically installs the driver. Press 'Finish' to close the wizard, and then restart the computer to allow the recognition of the webcam. Choose the option "Install the software manually" in order to access the location of the driver where you saved the driver and install it from there. Use the open file manager and search for the driver. Click on the ' next > ' button to install the driver, and then restart the computer to add webcam functionality. -ehow.com
