The videometry option works as an integrated function of PL-Winsor so there is no additional learning necessary of other software programs or systems; the PL-Winsor offers intuitive familiarity!
The PL-VIDEO-HD offers zoom, split-screen mode, single picture mode with slow-motion replay, fast scrolling of EEG with video playback synchronised including cut & paste functions whilst retaining all EEG data
Online network review: You may look into running videometry recordings from remote locations by a simple double-click at the PL-Winsor database window
All patient data, EEG, video and audio files can be archived and registered in the PL-Winsor database
Archiving of the complete video stream, or of selected segments, together with the EEG data on hard disk
Synchronised EEG, video and audio may be copied to external media for review using the free PL-Winsor reviewer on any modern PC
