AP-NR2000 Network DVR Server is a digital video recording and processing device based on the advanced next-generation networks. This product is configured with 2-port 10/100/1000 Mbps Gigabit interfaces, module-type power redundancy, and 10 IDE-type 3.5-inch HDD module slots, and enables RAID1 configuration. AP-NR2000 is available in various multimedia network environments such as VoD proxy servers.

The demand for the embedded network DVR server that supports reliability and high quality video services has been increasing as network-based high quality multimedia communication services such as network DVR and VoD proxy servers are getting popular.
If AP-NR2000 is used as a network DVR streaming server, install a hard disk on the front panel to provide services. A hard disk of 300 Gigabytes can accommodate 3 terabytes of DVR storage capacity, and RAID1 configuration enables DVR streaming services of 1.5 terabytes.

Hardware Embedded Network DVR Server

AP-NR2000 is an advanced device where the high quality CPU module designed and developed by AddPac is combined with real-time OS (APOS) and embedded hardware to provide network-based DVR server services. An advanced embedded RISC processor and a reliable embedded OS that support Gigabit Ethernet are used for this product to ensure better performance and efficiency.

Firmware Upgrade-Enabled DSP-Based HW Codec

Since the high-performance RISC processor modules installed into AP-NR2000 are all programmable, the features of AP-NR2000 can continue to be improved, changed, or added. You can flexibly adapt to future technology evolution. If you download an added or changed feature from the home page directly or set an automatic upgrade option whenever feature addition or change is done, you can use the latest feature without further operations.

Various Network Features and Advanced QoS Feature

AP-NR2000 supports the latest features and advanced services ranging from the ones (e.g. a variety of network protocols, better Quality of Service (QoS), and the error concealment technology) specialized for an environment for video communication services to the Virtual Router Redundancy Protocol (VRRP) service for preventing a failure and load balancing. Accordingly, AP-NR2000 can address various issues that may occur depending on network environments.

Available in a variety of multimedia network environments such as multi-channel video surveillance and VoD proxy servers

Video Surveillance: A video bit stream (e.g. network cameras) compressed into MPEG-4 is transmitted from a remote site to the network DVR server and saved in the DVR server in real-time. This product is applicable to surveillance systems such as traffic monitoring, environment monitoring, and accident monitoring. The manager can perform real-time surveillance through a large monitor such as TV or a real-time video decoder. Also, a PC-based DVR client viewer allows the manager at a remote site to perform video surveillance. This product is applicable to surveillance systems such as traffic monitoring, environment monitoring, and accident monitoring.

VoD Proxy Server: AP-NR2000 in addition to the VoD server solution of AddPac can function as a VoD proxy server. The VoD server on Internet networks has the limitations of providing high quality VoD services due to the restriction of a transmission bandwidth on a network and the limitations of QoS assurance. To resolve this issue, AP-NR2000 VoD Proxy Server performs the local cache function for VoD services in a corporate network. Using this technique, AP-NR2000 can provide high quality VoD services to service subscribers.
