Hanwha HRX-1635-30TB 16CH Pentabrid DVR
The Hanwha HRX-1635-30TB is a 16-channel pentabrid DVR purpose-built for hybrid analog and IP surveillance deployments. This 5-in-1 recorder accepts AHD, HDTVI, HDCVI, CVBS analog signals, and IP network cameras on a single platform without external converters, making it the ideal solution for integrators upgrading legacy systems or managing mixed-signal environments. With 30TB of onboard storage and NDAA/FCC compliance, the HRX-1635 delivers enterprise-grade recording reliability and regulatory adherence.
Key Features
- Pentabrid Input Architecture: Supports AHD (8MP, 5MP, 4MP, 1080p, 720p), HDTVI (8MP, 5MP, 4MP, 1080p, 720p), HDCVI (8MP, 5MP, 4MP, 1080p, 720p), CVBS (NTSC/PAL), and IP network cameras without converters
- High-Resolution Analog Recording: Captures up to 8MP at 15 fps, 5MP at 20 fps, 4MP/2MP/1MP at 30 fps, plus 960H/720H at 30 fps per channel
- Efficient Compression: H.265, H.264, and MJPEG codec support; maximum recording bandwidth of 128 Mbps and playback bandwidth of 32 Mbps
- Expandable Network Integration: Default 2-channel network camera capacity (expandable to 18 channels depending on analog channel allocation); supports SUNAPI (Wisenet) and ONVIF protocols
- Advanced Analytics: Motion detection, video loss detection, tampering detection, and network camera analytics (sensor-based MD, video analytics, defocus detection, audio analysis)
- Audio Support: Integrated audio input for multi-sensory event documentation
- PoE Compatibility: Powers PoE-enabled network cameras for simplified cabling and infrastructure
Technical Highlights
The HRX-1635-30TB delivers flexible frame rates optimized for different resolution tiers, enabling users to balance image clarity with storage efficiency. H.265 compression reduces bitrate by up to 50% compared to H.264 while maintaining visual quality, extending storage life on the 30TB capacity. Network camera analytics leverage Wisenet sensor and defocus detection to trigger alerts based on scene quality and intentional obstruction, while motion and video loss detection provide foundational edge-based surveillance monitoring.
VMS integration spans Wisenet Viewer, Wisenet Mobile app, and industry-standard ONVIF, allowing seamless integration into multi-brand ecosystems. The pentabrid architecture eliminates the need for signal converters, reducing installation complexity and cost in retrofit and hybrid deployments.
Ideal Applications
- Mixed analog/IP surveillance transitions and upgrades
- Enterprise facilities requiring NDAA-compliant recording (government, critical infrastructure)
- Multi-site deployments with legacy analog camera bases
- Retail, hospitality, and commercial security operations
- Integration-focused installations leveraging ONVIF interoperability

The HRX-1635-30TB excels in heterogeneous environments where analog and IP systems coexist. Its pentabrid design and 16 analog + 2 expandable network channels provide significant future-proofing without requiring complete system replacement. H.265 compression and 30TB storage deliver cost-effective long-term retention, while built-in analytics (motion, tampering, defocus) reduce dependency on external VMS processing.
NDAA compliance and Wisenet ecosystem integration make this unit particularly suited for regulated environments and organizations invested in Hanwha's platform. The 480 fps network camera capability supports high-speed motion analysis for critical monitoring scenarios, though users should verify bandwidth availability on their network infrastructure.
