The error “Failed to save image to temporary file” can happen if the filename to upload to the server is not a JPG or PNG file.
To check the filename:
- Open the KABcam settings
- Navigate to Snapshot->Destination->Server
- In the Filename field make sure the filename ends with a .jpg or .png
If KABcam doesn’t run or runs and immediately crashes when run on the German language edition of Windows Server 2016 you will need to disable DEP for KABcam.
To disable DEP for KABcam:
- Right click the Start Menu and click System
- On the left click Advanced System Settings
- Click the Advanced tab
- Click the Settings button
- Click the Data Execution Prevention tab
- Enable the option Turn on DEP for all programs and services except those I select:
- Click the Add button near the bottom
- Browse and select the file C:\Program Files (x86)\KAB Software\KABcam\KABcam.exe
- Click the OK button to save the change
This will allow KABcam to to run properly.
The error “Failed to read initial server version string” is usually caused by SSH being blocked by a firewall. Make sure your Windows firewall or security software is not blocking port 22. If you are behind a router or firewall device make sure it is not blocking port 22.
This information only applies to KABcam version 5 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 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.
