Hanwha HRX-1635-24TB 16CH Pentabrid DVR - 24TB Raw Storage

The Hanwha HRX-1635-24TB is a 16-channel pentabrid DVR engineered for mixed-signal surveillance environments requiring flexibility across analog and network camera technologies. This hybrid recorder accepts AHD, HDTVI, HDCVI, CVBS (analog), and IP inputs on a single platform, eliminating costly infrastructure overhauls during system upgrades or heterogeneous deployments. With 24TB of pre-installed raw storage, H.265 compression, and NDAA/FCC compliance, it delivers enterprise-grade reliability for integrators and security managers overseeing medium-scale operations in retail, education, municipal, and corporate facilities.

Key Features

Mixed-Signal Input Architecture: 16 dedicated analog channels supporting AHD, HDTVI, HDCVI, and CVBS signals, plus up to 2 network camera channels for 18 simultaneous inputs. Analog and IP cameras operate seamlessly in parallel, protecting legacy CVBS investments while enabling modern IP expansion.

Multi-Resolution Analog Capture: Records analog signals at 8MP (15 fps), 5MP (20 fps), 4MP (30 fps), 2MP (30 fps), 1MP (30 fps), and 960H/720H (30 fps) per channel. Independent per-channel configuration optimizes bandwidth and storage allocation based on operational requirements.

Network Camera Support: Integrates up to 18 IP cameras via SUNAPI (Wisenet) and ONVIF protocols with high-frame-rate event capture capabilities.

Advanced Compression: H.265 codec reduces file sizes and storage demands while maintaining image quality across mixed resolution inputs.

Audio Integration: Audio input support enables synchronized voice recording for enhanced incident investigation and compliance documentation.

Regulatory Compliance: NDAA and FCC certified for government, education, and enterprise deployments with strict procurement standards.

Ideal Applications

This DVR excels in environments where analog legacy systems coexist with newer IP infrastructure. Common deployments include retail chain stores with existing analog camera plants, educational institutions upgrading surveillance incrementally, municipal facilities managing multi-site monitoring, and enterprise campuses with heterogeneous camera ecosystems. The flexible input architecture reduces total cost of ownership during technology transitions.

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

The HRX-1635-24TB addresses a critical market gap: the need for hybrid recorders that genuinely support pentabrid inputs without forcing end-users into wholesale replacements. Unlike single-standard recorders, this platform enables staggered camera upgrades, reducing capital expenditure in budget-constrained organizations. The independent per-channel frame-rate and resolution controls are particularly valuable for bandwidth-limited networks or storage-constrained installations.

H.265 compression delivers approximately 50% storage savings versus H.264, extending the operational life of the 24TB capacity. NDAA certification signals suitability for federal, state, and local government procurement. Integrators should note the 2-channel IP limit; deployments exceeding 16 analog + 2 IP inputs require supplementary NVR infrastructure.
