I would like to suggest having a user positioned or configured-- date/time/text --overlay that is scale / rotation invariant integrated with the "Take Screenshot" function. This could allow users to zoom in on a region of interest and take a photo(Screenshot) of that region which includes the camera name plus date-time on the png.
Additionally, exposing / publishing a server side Onvif or Vapix style "Text Overlay HTTP-API" for licensed channels might help facilitate Point of Sale, SCADA and other "text inserter" type features.
Perhaps something like the following pseudo PUT request.
put('http://HDWITNESS-SERVER:7001/Video/Inputs/channels/1/overlays/text', auth=('user','passwordhash'),data=(XML or JSON for position, font and text))
Thanks for your consideration and congratulations on a great VMS.
