Network Video Recorder
Chapter 1 — Introduction
1.1 Features
This network video recorder (NVR) provides monitoring of video from network video transmitters, network
cameras and DVRs, recording of monitoring video (DVR excluded) and playback of video recorded in the
NVR system or DVR.
• Remote monitoring of live images
• Remote monitoring of live images in multiple Client systems through a streaming service (the number
of channels that can be streamed equals the number of channels that can be recorded)
• Up to 20 simultaneous connections to the NVR system
• Software upgrades and multiple systems setup remotely (supported only for devices which provide the
functions)
• Display of system log information (supported only for devices which use the SiRiS protocol)
• Map monitoring of live images
• Centralized system operation and management and event handling
• Enhanced security using the SSL function
• Two-way audio communication and audio broadcasting
• Enhanced security by setting up different authorities for each user group
• Controlling with a network keyboard
• Text-in and alarm function via TCP networking
• Intuitive GUI
• The following are supported only for network cameras and network video transmitters:
− Recording of video and playback of the recorded video
− Instant Recording of monitored images
− Audio recording
− Stable recording using proprietary video database file system
• The following are supported only for DVRs:
− Playback of video recorded in DVRs
− Remote control of panic recording
• Number of devices that can be registered and channels that can be recorded and streamed:
− Registration: Maximum of 1,024 devices including devices which do not use the SiRiS protocol (The
devices which do not use the SiRiS protocol can be registered up to the maximum number of available
recording channels. For example, if the NVR system is a 16-channel model, up to 16 devices that do
not use the SiRiS protocol can be registered.)
− Recording (not supported for DVRs): Maximum of 16 (16-channel model) /32 (32-channel model) channels
− Streaming (not supported for DVRs): The number of channels that can be streamed equals the number
of channels that can be recorded.
NOTES:
• In this document, the “remote system” refers to a network video transmitter or DVR which cameras are
connected to or a network camera. The “client system” refers to a PC running the Client program to
connect to the NVR system remotely.
• If the device is a four-channel network video transmitter which uses the SiRiS protocol, all four cameras
are counted even if some of the four cameras are disabled, and four channels per network video transmitter
are deducted from the number of channels available for recording and streaming.
• This document covers the 16- and 32-channel network video recorders. For simplicity, the illustrations
and descriptions in this document refer to the 32-channel model. Refer to Appendix (p. 141) for the
system specifications of each model.
