This is adapted from the forum post (src: https://forums.zoneminder.com/viewtopic.php?p=130513), but for redundancy will be put here:
ZM has a number of command line tools which do various swiss army like tasks for zm. Try typing zm, then hitting 'tab' for autocomplete in bash, to get a list of them. One of them, zmu, can give you a screenshot of a monitor. Such as:
zmu -v -m ## -i -U username -P password.
See zmu -h for more details.
