The aim of this study was to develop a home-monitoring system for recording and analyzing infant movement using image processing during nocturnal co-sleep, and to construct platform to network among pediatric sleep researchers.The equipment for the video monitoring system consisted of digital camera, Vari-zoom-lenses, near infrared LED, Image Recording Tool (including a computer to record infant's state), and Video Analysis Viewer for automatic analyses. We examined whether this system was robust for recording and detecting three infant states : quiet sleep, active sleep and awake. The range of interrater agreements of each infant's state was between 0.59-0.77. This newly developed video monitoring system shows good potential as a reliable robust system able to automatically detect infant-sleep wake state.
