Hanwha HRX-1635-4TB 16CH Pentabrid DVR - 4TB Raw Storage

The Hanwha HRX-1635-4TB is a 16-channel pentabrid DVR engineered for integrators and IT managers deploying mixed analog and network camera environments. This 5-in-1 recorder accepts AHD, HDTVI, HDCVI, CVBS (analog), and IP inputs on a single platform, eliminating the need for separate recorders and reducing deployment complexity. With support for up to 8MP analog cameras and expandable network camera channels, the HRX-1635-4TB delivers scalable recording capacity for small to mid-sized security installations.

Key Features

Pentabrid Input Architecture: Single recorder accepts AHD (8MP, 5MP, 4MP, 1080p, 720p), HDTVI (8MP, 5MP, 4MP, 1080p, 720p), HDCVI (8MP, 5MP, 4MP, 1080p, 720p), CVBS (NTSC/PAL), and ONVIF/Wisenet IP cameras without mixed-platform complexity

Multi-Resolution Analog Support: Records analog cameras at 8MP (15 fps), 5MP (20 fps), 4MP (30 fps), 2MP (30 fps), 1MP (30 fps), and 960H/720p (30 fps) per channel, accommodating both legacy and modern analog deployments

Network Camera Expansion: Supports up to 2 network camera channels standard, expandable based on analog channel configuration; network cameras record at up to 2MP at 30 fps or up to 480 fps in burst mode

H.265 Compression: Advanced video compression reduces storage requirements while maintaining image quality across all input types

Expandable Storage: Includes 4TB raw storage with support for up to 8 SATA HDD slots for 48TB total capacity

Audio Support: Integrated audio input for comprehensive surveillance coverage

Applications

The HRX-1635-4TB is ideal for retail environments, office buildings, industrial facilities, and educational institutions requiring flexible camera integration. Its pentabrid architecture simplifies system upgrades when transitioning from analog to IP cameras, protecting existing analog camera investments while enabling modern network camera expansion. Organizations can deploy higher-resolution analog cameras (up to 8MP) alongside IP cameras without separate recorder infrastructure.

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

The pentabrid design addresses a critical market need: mixed-camera environments are common in legacy system upgrades. Rather than requiring customers to replace working analog infrastructure or deploy dual recorders, this unit consolidates everything into one device. The H.265 compression codec is particularly valuable for high-resolution analog recordings, reducing storage costs significantly compared to H.264 while maintaining compatibility with modern IP cameras.

The expandable network channel capability (up to 18 total) provides future-proof scalability without requiring hardware replacement, making this recorder a cost-effective solution for growing security deployments.
