Neuron-Spectrum-Video General Properties 

·                   Synchronous long-term recording of EEG and video

·                   Video recording from one or two video cameras (short-distance infrared video camera and general view camera)

·                   Night videomonitoring when using video camera with infrared highlighting

·                   Audio information recording from one or two microphones (patient's microphone and medical staff's microphone)

·                   Events marking in the process of recording

·                   Synchronous review of recorded EEG and video information on one (PIP) or two monitors with common/increased speed or by frames

·                   Instant positioning of video, basing on EEG temporary slice; EEG positioning basing on the video frame

·                   Instantaneous moving to selected event marker, video fragment or definite point of time

·                   Wide capabilities of recorded EEG mathematical analysis and brain mapping

·                   Editing of recorded video EEG for saving only significant fragments

·                   EEG and video data storing on CD or standard video cassettes
