Hanwha HRX-1635-36TB 16CH Pentabrid DVR with 36TB Storage

The Hanwha HRX-1635-36TB is a professional-grade 16-channel pentabrid DVR engineered for hybrid analog and IP surveillance deployments requiring substantial storage capacity and flexible input architecture. This standalone recorder combines legacy analog camera support with modern network camera integration, delivering up to 18 total recording channels with 36TB of pre-installed raw storage—ideal for mid-to-large security integrations demanding extended retention periods without external storage dependencies.

Key Features

Pentabrid Input Architecture: Records simultaneously from 16 analog channels supporting AHD, HDTVI, HDCVI, and CVBS formats with capacity to add up to 2 network IP cameras for maximum flexibility

8MP Analog Resolution: Analog channels deliver up to 8MP recording at 15 fps (NTSC) or 12 fps (PAL), with scalable options including 5MP at 20 fps, 4MP at 30 fps, 2MP at 30 fps, and 960H/720H at 30 fps

36TB Raw Storage Capacity: Pre-configured with up to eight 6TB SATA HDDs, providing extended video retention without additional investment

Multi-Codec Compression: H.265, H.264, and MJPEG support with 128 Mbps maximum recording bandwidth and 32 Mbps playback bandwidth for efficient storage utilization

Audio Support: Integrated audio input capability for synchronized audio and video recording across channels

Dual-Stream Technology: Enables simultaneous multi-user access and flexible bandwidth management for concurrent viewing and playback operations

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The HRX-1635-36TB addresses a practical market need: organizations with existing analog camera investments who require modern recording capabilities without complete infrastructure replacement. The pentabrid approach—supporting four distinct analog standards plus IP—reduces integration complexity across diverse installations. H.265 compression is particularly valuable at this channel density, delivering 30-50% bitrate reduction versus H.264 while maintaining 8MP fidelity, directly extending the effective storage duration of the 36TB capacity.

The 128 Mbps recording bandwidth ceiling is sufficient for 16 channels at mixed resolutions (typical deployments blend 8MP, 4MP, and 2MP streams). For organizations requiring pure IP architectures, Hanwha's NVR lineup offers alternative options; this DVR excels in hybrid environments where analog camera bases justify continued investment.
