Hanwha HRX-835A-8TB Pentabrid 8MP DVR Recorder
The Hanwha HRX-835A-8TB is a professional-grade pentabrid DVR engineered for mixed-camera surveillance deployments. This 8-channel recorder accepts AHD (up to 8MP), TVI (up to 8MP), CVI (up to 5MP), CVBS, and IP cameras (up to 8MP), with support for up to 10 network channels. Pre-configured with 8TB of storage and expandable to 24TB across four SATA drives, the HRX-835A-8TB delivers flexible architecture for mid-to-large security installations where analog and network technologies must coexist.
Key Features
- 8-channel analog input (AHD, TVI, CVI, CVBS) + up to 10 IP channels
- 8MP analog recording at configurable frame rates; 8MP IP support via SUNAPI and ONVIF
- H.265, H.264, and MJPEG triple-codec compression at up to 80Mbps recording bandwidth
- Pre-installed 8TB HDD; expandable to 24TB maximum (4x 6TB SATA drives)
- Dual monitor output: HDMI 4K and VGA with independent control
- 8 audio inputs, 1 audio output; 8 alarm inputs and 4 relay outputs for external integration
- 32Mbps playback bandwidth supporting up to 10 simultaneous remote users
- PTZ coaxial control and QR code mobile configuration
Format Support & Recording Performance
Analog Channels: AHD supports 8MP (8fps), 5MP (12fps), and 4MP (15fps); TVI and CVI support 8MP, 5MP, 4MP, 1080p, and 720p resolutions; CVBS (NTSC/PAL) for legacy cameras.
IP Channels: Up to 10 channels at CIF through 8MP via SUNAPI (Wisenet) and ONVIF protocols. Dual-stream recording with normal, scheduled, and event-triggered modes maximizes storage efficiency and operational flexibility.
Display & Connectivity
Dual HDMI 4K and VGA outputs enable independent multi-monitor configurations, while a dedicated spot monitor output prioritizes alarm feeds. Eight audio input channels with one output support integrated voice and alert systems. Eight alarm inputs and four relay outputs facilitate integration with access control, lighting, and third-party security devices. Built-in QR code support streamlines remote mobile access setup without complex networking configuration.
Applications
Ideal for retail chains, warehouses, manufacturing facilities, and enterprise campuses where existing analog investments must integrate with newer IP infrastructure. The pentabrid design eliminates costly forklift upgrades, allowing phased migration to higher-resolution IP cameras while maintaining legacy AHD/TVI/CVI systems.

The HRX-835A-8TB balances backward compatibility with modern compression efficiency. H.265 codec delivers superior bitrate optimization versus H.264, reducing storage costs on 24TB maximum configurations. The 80Mbps recording bandwidth caps simultaneous streams, requiring careful resolution/frame-rate planning for full-capacity 10-IP deployments.
Pentabrid architecture justifies mid-market adoption where analog infrastructure retirement timelines span 2-3 years. The 32Mbps playback limit supports moderate concurrent remote viewing but may bottleneck during forensic review of multiple high-resolution streams. Recommend pairing with managed network infrastructure and UPS backup for continuous operation in mission-critical environments.
