When the installation is started, the installation program will scan your PC. If it finds another 2N® Lift8 get-cam-image  installation, it will ask you whether to uninstall the existing version.

By default, C:\Program Files (x86)\2N TELEKOMUNIKACE\2N Lift8\get-cam-image is used. Click Next to make the wizard install 2N® Lift8 get-cam-image.

Once installed, the application is ready for use.

To download an image, enter the following into the command line:

Get-cam-image.exe [Options] intercom contact number


  • Output file name (test.jpg, e.g.)
    • Number of the shaft where the camera module is installed (1–8)

Example: Get-cam-image.exe -o test.jpg -s -p 7008 -u novak -w 1234 603123456

The application downloads the image from the intercom camera in shaft 3 whose contact number is 603123456 and gets connected to the server on the address and port 7008 using user novak and password 1234 for login. The image is saved into the default directory under the name of test.jpg.
