Hanwha HRX-1635-20TB 16CH Pentabrid DVR with 20TB Storage

The Hanwha HRX-1635-20TB is a 16-channel pentabrid digital video recorder engineered for security integrators and IT managers deploying hybrid analog and IP surveillance systems. This 5-in-1 hybrid recorder accepts AHD, HDTVI, HDCVI, CVBS, and network camera inputs in a single unified platform, supporting analog resolution up to 8MP and eliminating infrastructure redundancy. Pre-configured with 20TB raw storage and NDAA/FCC compliant, it is purpose-built for mission-critical and government-regulated deployments.

Key Features

Pentabrid Input Architecture: 16 analog channels (AHD, HDTVI, HDCVI, or CVBS) plus up to 2 additional network camera channels for mixed deployments, with network channel count inversely dependent on analog channel utilization

8MP Maximum Analog Resolution: Records analog cameras at up to 8MP (15 fps), 5MP (20 fps), 4MP (30 fps), 2MP (30 fps), 1MP (30 fps), and 960H/720H (30 fps) per channel with independently configurable frame rates

Advanced Compression Support: H.265, H.264, and MJPEG codecs with maximum recording bandwidth of 128 Mbps and playback bandwidth of 32 Mbps for efficient storage utilization and multi-user playback

Audio Integration: Audio input support for synchronized multimedia recording and playback

Expandable Storage: Ships with 20TB raw capacity, expandable to 48TB maximum via 8 SATA HDD slots supporting drives up to 6TB each

Flexible Channel Configuration: Dynamically allocate channels between analog and network inputs based on deployment requirements

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

The HRX-1635-20TB's pentabrid architecture eliminates the common integration challenge of managing separate DVR and NVR systems in hybrid environments. The H.265 compression codec delivers superior storage efficiency compared to H.264, extending retention periods or supporting higher frame rates within fixed storage budgets. With 20TB pre-configured capacity and maximum expandability to 48TB, this recorder accommodates extended 24/7 recording scenarios across 16 channels.

NDAA compliance and FCC certification make it suitable for federal, state, and local government procurement. The independently configurable frame rates across channels allow optimized bandwidth allocation—allocating higher frame rates to high-traffic areas while reducing redundant captures in low-activity zones. Security integrators will appreciate the flexible analog/network channel allocation, which accommodates phased camera system upgrades without requiring complete recorder replacement.
