Digital Watchdog DW-BJNAS20TR Network Attached Storage
Overview
The DW-BJNAS20TR is a 10TB network-attached storage unit purpose-built for Digital Watchdog Blackjack surveillance systems. It extends recording capacity and enables centralized backup across Blackjack-series deployments without requiring additional NVR hardware. Deploy this when your primary recorder hits storage limits or when you need isolated backup storage on the same network segment.
Compatibility
This unit integrates with Digital Watchdog Blackjack-series network video recorders and storage systems. Confirm your specific Blackjack model number against Digital Watchdog documentation for network binding and RAID configuration requirements before deployment.
Storage and Redundancy
10TB usable capacity with RAID 1 (mirrored) support — write operations are mirrored across physical drives, meaning you lose half the raw capacity to redundancy but gain protection against single-drive failure. Transfer rate of 0.16 Gb/s (roughly 20 MB/sec) is adequate for single-stream playback and archive retrieval, but is not optimized for multi-camera simultaneous write scenarios. If you need high-throughput live record from many cameras, verify network bandwidth availability and NVR write scheduling with your Blackjack control unit before committing.
Network Integration
Connect via standard Ethernet to your surveillance network. The unit operates as a NAS (network-attached storage) and is managed through the Blackjack system interface — direct SSH or NAS-native management tools are typically not exposed. Ensure your network switch has available ports and your Blackjack recorder supports external NAS binding in its firmware version.
