Hanwha HRX-1635 16CH Pentabrid DVR Recorder

The Hanwha HRX-1635 is a versatile 16-channel pentabrid digital video recorder engineered for professional surveillance deployments requiring flexible camera compatibility and high-resolution recording. Supporting five input types—AHD, HDTVI, HDCVI, CVBS, and IP—this DVR accommodates mixed analog and network camera ecosystems, making it ideal for system expansion and hybrid infrastructure environments.

Key Features

• Pentabrid architecture supporting AHD, HDTVI, HDCVI, CVBS, and IP inputs
• 16 analog channels plus up to 18 network camera channels for total flexibility
• 8MP analog camera recording at 15 fps; 5MP at 20 fps; 4MP/2MP at 30 fps
• Dual video output: HDMI 4K-ready and VGA for dual-monitor configurations
• 128 Mbps maximum recording bandwidth with H.265, H.264, and MJPEG compression
• 8 SATA HDD slots supporting up to 6TB drives for 48TB total capacity
• 16 alarm inputs and 4 relay outputs for integrated event management
• Coaxial PTZ control via RS-485/422 protocols (Pelco-D/P, Samsung-T)

Recording & Playback Capabilities

The HRX-1635 delivers comprehensive recording flexibility with multiple modes including continuous, scheduled, and event-triggered recording with pre/post-event buffering. Advanced event triggers span video loss detection, motion detection, tampering alerts, and camera-level analytics for network sources. Event actions include email notifications, FTP uploads, PTZ preset execution, and external alarm relay activation. Simultaneous playback supports 18 channels locally, 18 channels via CMS, 4 channels via mobile app, and single-channel web access. Maximum playback bandwidth reaches 32 Mbps across all connected streams.

Remote Access & Mobile

Built-in Wisenet DDNS and P2P connectivity enable QR code-based device pairing for rapid remote setup. iOS and Android mobile support includes live streaming across 16 channels with multi-profile adaptation, 4-channel simultaneous playback, and real-time event push notifications. Web-based access, SmartViewer software, and SSM provide flexible monitoring from Windows/Linux environments. Up to 10 concurrent unicast live users and 3 search users ensure scalable remote operations.

Security & Reliability

Enterprise-grade security includes IP address filtering, user access logging, 802.1x authentication, and encryption of credentials, recordings, transmissions, and backups. Device certificates via Hanwha Techwin Root CA authenticate hardware integrity. Automatic Redundancy Backup (ARB) protects critical recordings. Setup Wizard automates initial configuration including language, date/time, network parameters, and camera auto-detection.

Applications

• Mixed analog-to-IP surveillance transitions
• Retail and commercial security networks
• Multi-site enterprise deployments via CMS integration
• High-capacity archival and long-term retention
• Industrial facilities requiring PTZ integration

Physical & Operational Specifications

Compact 1U form factor (440 x 88 x 384.8 mm) delivers rack-mount capability. Operating range spans 0–40°C at 20–85% humidity. Universal AC input (100–240V, 50/60 Hz) with peak 200W consumption supports global deployment. Multilingual interface covers 23 languages. UL, CE, FCC, KC, and UKCA certifications ensure regulatory compliance.

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

The HRX-1635 excels as a bridge solution for organizations modernizing surveillance infrastructure. Its pentabrid design eliminates the need for parallel analog and IP recorder systems, reducing capital and operational overhead. Support for 8MP analog sources justifies investment in existing HD camera plant while enabling gradual network camera adoption.

The 128 Mbps recording ceiling and 48TB storage capacity suit organizations requiring 30+ days of continuous multi-channel retention at high resolution. Dual HDMI/VGA output is particularly valuable in NOCs requiring simultaneous monitoring across redundant displays. However, the 2-channel native IP input (expandable to 18) subordinates network camera throughput compared to dedicated NVRs, making this recorder optimal for minority IP camera deployments rather than pure-IP environments.

Coaxial PTZ control via RS-485 ensures compatibility with legacy PTZ domes, essential for retrofit projects. Integration with Wisenet CMS and third-party VMS platforms via ONVIF and SUNAPI APIs positions this unit as an enterprise-grade component within larger security ecosystems.
