PREFACE

The Digital Disk Recorders WJ-HD316/309 are designed for use within a surveillance system and are a combination of a hard disk recorder and a video multiplexer (16-input for the WJ-HD316, 9-input for the WJ-HD309).

The digital hard disk recorder is a recording device using a hard disk drive to record camera pictures instead of using videotapes so that pictures recorded by repeated overwrit- ing will not cause deterioration of the recorded picture qual- ity. Up to 16 cameras can be connected to the WJ-HD316

directly (up to 9 cameras to the WJ-HD309) and it is possi- ble to record their camera pictures. It is also possible to display four or more camera pictures on a single monitor, to switch camera pictures, and to operate cameras using this unit.

FEATURES

Various Recording Functions

•Multi-Recording

It is possible to perform multiple recording using a sin- gle digital disk recorder even if the operating environ- ments are different, for example, recording pictures of cameras in different places at different times.

Remote Operation via Network

It is possible to operate this unit using a PC connected to a LAN (Local Area Network) or the Internet by the featured network function.

•Schedule recording

It is possible to perform recording automatically at a scheduled time on a designated day of the week. Schedules can be set on each camera.

•Emergency Recording

In case of emergency, emergency recording will be given a higher priority than other recording modes by operating an external switch.

•External Timer Recording

It is possible to perform recording automatically using an external timer.

•Event Recording

At an event occurrence, such as when an alarm signal is supplied, the recording mode (quality and recording rate) can be changed to high quality to record pictures.

•Motion Detection Function (VMD)

It is possible to start recording automatically when motion is detected in a shooting area.

Frame Switcher Function

•It is possible to display pictures of four or more cam- eras on a single monitor (multi-screen) splitting the monitor screen into 4, 7, 9, 10, 13, or 16 sections using the WJ-HD316, and into 4, 7, or 9 sections using the WJ-HD309.

While monitoring a multi-screen, each camera picture will be displayed as a moving image.

Security Function and Reliability

•Authentication function (registration of ID and pass- word) allows users access to a predetermined selection of the available functions. Up to 32 users can be regis- tered.

•If alteration of a recorded image data is made for any reason, the alteration alert function will announce it.

•If a hard disk crashes, the backup function*1, the mirror- ing function*2 and the RAID 5 function*3 prevent there being any data loss.

*1: Only when the recommended DVD-RAM drive, DVD-R drive or CD-R drive is used

*2: The mirroring function does not work with an external hard disk drive such as an extension unit.

*3: To use the RAID 5 function, an optional extension unit is required.

Transmission with Coaxial Cable, PS·Data and RS485 Compatible

•It is possible to control a Panasonic combination cam- era such as the WV-CS850 using only a coaxial cable but not other devices. Using a coaxial cable also com- pensates for transmission loss.

•It is easy to establish the surveillance system by con- necting a PS·Data compatible system controller and peripherals.
