Preface

The Network Disk Recorders WJ-ND200 series are designed for use within a surveillance system, and perform recordings and
playbacks pictures from network cameras in the system.

the settings or operate the WJ-ND200 (this unit) using a web browser installed on a PC connected to a network. Up to 4 PCs
(web browsers) can access this unit concurrently and it is possible to perform the settings and operate this unit.
