Zoneminder can not only record cameras, but can also do screen recording of Windows/Linux/Mac or any computer that uses VNC. LibVNC in 1.36 is a way to record VNC sessions. Any VNC server should be able to be used, but this guide has tested only TightVNC.

Setup

Using TightVNC on Windows

1. Install TightVNC. https://www.tightvnc.com/download.html

2. Setup a view only user with a password. Disable the primary user and also disable the java client. There is also the Access Control page where you can optionally put firewall rules in to only allow access to the ZM server.

My settings in Zoneminder look something like this. Note that I've specified to record only 2 FPS. For LibVNC, you should specify a max FPS. 2 is enough for my use case. Also note that there is no username, and instead just a password is used. The resolution may be any value that you want to record at. I have not tested how it affects performance, but have had success with both 1600x600 and also at say 320x240.

If everything goes right, you should have the computer screen recording in Zoneminder. Note: There has been a bug where the computers, if shut down then the recording will freeze in ZM. This can be avoided by restarting the monitor or ZM service after the computer is shut off (e.g. overnight).
