  3. Click the Advanced tab
  4. Click the Settings button

  7. Click the Add button near the bottom

This information only applies to KABcam version 5.  You do not need to download FFmpeg for version 6 and higher.

For network cameras that only provide a video stream KABcam uses FFmpeg to extract a snapshot from the stream.

FFmpeg is a free, open source program for handling audio, video and multimedia files and streams.  Due to patent and licensing concerns FFmpeg is not included with KABcam. This FAQ will help you download and setup FFmpeg for use with KABcam.

FFmpeg is licensed under the GNU Lesser General Public License (LGPL) version 2.1 or later. However, FFmpeg incorporates several optional parts and optimizations that are covered by the GNU General Public License (GPL) version 2 or later. If those parts get used the GPL applies to all of FFmpeg. See https://www.ffmpeg.org/legal.html for more information.

KABcam calls FFmpeg as an external executable, it does not contain any FFmpeg source code or link to any FFmpeg binaries.

The download links on this page are for the executable program, source code for FFmpeg can be downloaded from www.ffmpeg.org.

Most network camera manuals provide the image or video stream in the camera manual, however not all do and not everyone still has the manual to their camera. If your camera manual doesn’t provide the URL you can try some of these common URLs, some of them are common across different manufactures so if you camera manufacturer isn’t listed you can try ones from other manufacturers

The list does not include every camera and we cannot guarantee these will work.  If you have a working URL that’s not in the list please contact kab software to have it added.

We recommend using an Image URL whenever possible.  When using one of the URLs replace [ipaddress] with the IP Address of your network camera.

You can capture from multiple cameras on the same computer by running multiple copies of KABcam with different settings files.

  2. Create a new shortcut to KABcam by right clicking on the KABcam icon and selecting Create Shortcut
  3. Right click on the new shortcut and select Properties
  4. In the Properties window on the Shortcut tab add a space to the end of the Target field followed by:

    KABcam version 5 and higher
    -config “NewSettings”

    Example: "C:\Program Files (x86)\KAB Software\KABcam.exe" -config "Logitech C270"

    KABcam version 4 and lower


    Example: "C:\Program Files (x86)\KAB Software\KABcam.exe" LogitechC270


  5. Click OK to close the Properties window.
  6. Start KABcam from the new shortcut and configure the settings for a different camera.


  • Each time you start KABcam with the new shortcut it will use the new settings file.
  • You can create multiple shortcuts with different settings.
  • You cannot have multiple copies of KABcam accessing the same camera.
  • The settings file for KABcam version 4 and lower cannot contain spaces.


KABcam v5 supports nearly all USB and built-in cameras and most network cameras.

KABcam v4 supports cameras that are available as WDM or VFW devices and network cameras that allow a still image to be viewed as a url.  KABcam v4 may not be able to select the correct camera when 2 or more cameras are connected to the computer.

The easiest way to tell if your camera will work with KABCam is to download the free 20 day trial.

If you placed your order between April 1st 2019 and August 1st 2021 you can view your purchase history from the Shopper Support page, otherwise please contact KAB Software.

This only affects KABcam version 4 and lower

At the end of March, 2016 Yahoo! shutdown the public weather server used by version 4 and lower, this does not affect version 5 and higher.
