OVERVIEW
DESCRIPTION
The DX3000 Series Digital Video Recorder (DVR) is a high-quality digital recorder that combines the functions of a recorder and multiplexer into one unit.
With the number of cameras in systems increasing, the combination of a video recorder with a multiplexer has become standard. In pursuit of the high-quality image playback char- acteristic of digital recording and as a way to make the recording operation more ideal, the DX3000 Series DVR includes versatile multiplexer functions that allow the images from the camera inputs to be shown on the monitor in multiple formats: 1-, 4-, or 9-camera dis- plays on the DX3009 models or 1-, 4-, 9-, or 16-camera displays on the DX3016 models.
The DX3000 Series DVR uses JPEG compression to produce high-resolution playback with more than 450 horizontal lines. There are five user-selectable image quality settings. The DVR has a built-in, large-volume hard disk for both high reliability and high-speed operation. Users can select from six (DX3009 models) or eight (DX3016 models) record- ing intervals ranging from 1-30 frames per second. The maximum number of frames that can be recorded consecutively is as follows:
MODEL | MAXIMUM FRAMES |
DX3009-030 | 2,456,000 |
DX3009-060 | 4,913,000 |
DX3016-060 | 4,800,000 |
DX3016-120 | 9,601,000 |
Recording can be done continuously or at specified time periods. The user also can cat- egorize cameras into three recording groups, allowing different recording patterns, for ex- ample, during weekdays and weekends.
Zoom buttons permit the user to zoom in on a selected area of the image.
There are two methods of detecting alarms. First, for each camera there is an alarm input that triggers alarm recording when a ground signal is received from the alarm device.
A pre-alarm recording function can be set to record images before the alarm sensor de- tects disturbances. Second, each camera can be programmed to detect motion, including the capability to select the motion detection area and the sensitivity of motion detection.
Versatile high-speed search operations include time and date searching, index searching, skip searching, and alarm list searching.
To handle applications requiring long-term storage of recorded images, the DX3000 Series DVR is capable of using supplementary devices to create backups and copies without inter- rupting hard disk recording. Used in conjunction with a wide selection of media, DX3000 Series DVR can handle many different kinds of non-stop recording. Additional hard disk drives can be added to supplement the built-in hard disk when extended recording time is needed, as follows:
MODEL | MAXIMUM NUMBER OF |
| ADDITIONAL HARD DRIVES |
DX3009-030 | 3 | (34 GB PER UNIT) |
DX3009-060 | 2 | (34 GB PER UNIT) |
DX3016-060 | 2 | (103 GB PER UNIT) |
DX3016-120 | 2 | (103 GB PER UNIT) |
Other features include audio recording, recognition of recorded images that have been al- tered, and an RS-232C interface for remote control from a PC or other control terminals.
