Product Overview
This section provides an overview of the NVR300 network video recorder, software version 3.00. The following information is provided:
•
Description of the functions and features of the NVR300, including a sample application scenario and network architecture considerations
•
Summary listing of the various NVR300 models
•
Front and rear views of the NVR300
DESCRIPTION
The NVR300 network video recorder records video and audio data streams received over Ethernet networks using the TCP/IP protocol.
The NVR300 receives compressed data streams generated by the PelcoNet
™
NET4001A, NET350T, and NET300T transmission systems, indexes
the data streams, and then records the streams onto hard disk drives (HDDs).
Features of the NVR300 include the following:
•
Video recording of MPEG-2 and MPEG-4 data streams at 48 Mbps for internal storage and 100 Mbps for external storage
NOTE:
The NVR300’s recording rate will be affected during a rebuilding of the RAID array.
•
Duplex operation: simultaneous recording on the NVR300 and remote playback on the VMX300 video management system or client PC on
the network
•
Continuous and event-based recording
•
High-speed embedded SQL database that stores data streams, allowing full-featured search capabilities: search based on camera, time,
and date
•
Internal storage of up to 1,500 gigabytes (GB)—internal RAID (Redundant Array of Independent Disks) Level 5 storage from 250 GB to
1,500 GB or non-RAID 250 GB to 1,250 GB
•
Expandable storage with up to two DX9200HDDI video storage units, allowing up to 7,000 GB of external storage (RAID Level 5) (storage is
expandable only for models with no internal storage)
•
Patented Automatic Data Replenishment (ADR) technology that ensures recording from the PelcoNET NET350T despite network failures
(detailed information about ADR is provided in the
Appendix
)
•
Digital certification by watermarking, which inserts an artificial electronic signature into a video picture to prove authenticity (watermarking
information is generated by the PelcoNet NET350T and NET300T devices, software version 2.10, and is recorded onto the NVR300)
•
Full integration with the VMX300 video management system
•
Integrated Web server functionality
The user interface to the NVR300 is Web based and can be accessed locally from the NVR300 unit itself or remotely from the VMX300 video
management system or from any client PC on the network. (Information about client PC system requirements is provided later in this manual.)
