Hanwha HRX-835A-24TB 8MP Pentabrid DVR Recorder
The Hanwha HRX-835A-24TB is a professional-grade 8-channel pentabrid DVR built for hybrid analog and IP surveillance environments. This versatile recorder eliminates the need for platform replacement by accepting AHD, TVI, CVI, and CVBS analog signals alongside IP cameras—all up to 8MP resolution. Pre-loaded with 24TB of raw storage across four SATA HDD slots, it provides extended retention for mission-critical continuous and event-triggered recording in enterprises, retail, government, and critical infrastructure installations.
Key Features
- 8-channel pentabrid input: AHD/TVI/CVI/CVBS analog + IP cameras (up to 8MP each)
- Expandable to 18 simultaneous monitoring channels (8 analog + 10 network via ONVIF/SUNAPI)
- 24TB pre-configured HDD storage across 4 SATA slots
- H.265, H.264, and MJPEG codec support with selectable compression per stream
- Maximum 80Mbps recording bandwidth; 32Mbps playback supporting 10 simultaneous streams
- Dual video output: HDMI (4K/2.5K/1080p) and VGA (1080p/720p)
- 8-channel audio input with 1-channel audio output
- 8 alarm inputs and 4 relay outputs for integrated security automation
- Coaxial PTZ control for analog camera devices
Recording and Compression Performance
The HRX-835A supports flexible resolution and frame rate combinations: 8MP at 8fps, 5MP at 12fps, 4MP at 15fps, 2MP at 30fps, plus 1080p and 720p at full 30fps. H.265 compression significantly reduces bandwidth and storage requirements compared to H.264, while maintaining image quality for forensic playback and evidence preservation. Triple codec flexibility ensures compatibility with legacy and modern camera deployments.
Connectivity and I/O Architecture
Eight BNC video inputs (75-ohm) accommodate analog cameras, while dual Gigabit Ethernet ports support IP camera expansion up to 10 channels. Spot monitor output, dual video displays, and comprehensive alarm I/O (8 in, 4 out) enable versatile control room configurations. Audio support across 8 channels facilitates two-way communication and event correlation.
Applications
- Retail and commercial facility surveillance
- Government and critical infrastructure monitoring
- Enterprise campuses with mixed analog/IP camera portfolios
- Transportation hubs and access control integration
- Systems requiring extended storage for compliance and forensic analysis

The HRX-835A-24TB addresses the real-world challenge of mixed-technology surveillance deployments. Organizations upgrading from legacy analog systems can integrate new IP cameras without replacing the entire infrastructure—a cost-effective migration path. The 24TB capacity suits environments with high-resolution (8MP) continuous recording or dense multi-channel deployments requiring 30+ day retention.
H.265 codec adoption is critical for managing bandwidth in bandwidth-constrained or distributed locations. The 80Mbps aggregate bandwidth cap requires careful stream allocation in maximum-density scenarios; 18-channel simultaneous monitoring demands prudent resolution/frame rate tiering. Suitable for mid-to-large organizations balancing performance, scalability, and total cost of ownership.
