Preface
The Digital Disk Recorder WJ-RT416 is designed for use within a surveillance system. The digital disk recorder is a
recording device using a hard disk drive to record pictures of surveillance cameras instead of using videotapes so
that pictures recorded by repeated overwriting will not experience deterioration of the recorded picture quality.
Up to 16 cameras can be connected directly with this unit and it is possible to record images from them. It is also
possible to display images from multiple cameras (multi-screen), to display images from a camera to camera
sequentially (sequential display), and to operate the connected cameras using the recorder.
Configuration of the settings of the recorder can be made using the monitoring software, and operation of the
recorder can be made using the monitoring software and a web browser.
