Hanwha HRX-835A-6TB vs Hanwha QRN-830S: Specification Comparison
Both the Hanwha HRX-835A-6TB and the Hanwha QRN-830S are 8-channel recorders sharing the same brand family, maximum 80 Mbps recording bandwidth, and H.265/H.264/MJPEG codec support. The critical architectural divide is recorder type: the HRX-835A-6TB is a pentabrid DVR accepting analog (AHD/HDTVI/HDCVI/CVBS) plus IP cameras, while the QRN-830S is a pure IP NVR. Buyers choosing between them are weighing an analog-legacy-compatible hybrid platform against a dedicated IP-only system with deeper network feature sets.

How do channel capacity and storage scalability compare between the two recorders?
The HRX-835A-6TB supports 8 analog channels (AHD/HDTVI/HDCVI/CVBS) plus 2 to 10 additional IP channels, yielding up to 18 total channels in a mixed deployment. It ships with 6TB pre-installed across one of four SATA HDD slots and is expandable to 24TB total. The QRN-830S is capped at 8 IP channels with a single SATA HDD slot supporting a maximum of 6TB and no stated expansion path beyond that ceiling.
For deployments that need to grow storage over time, the HRX-835A-6TB's four-slot, 24TB ceiling offers a clear advantage. The QRN-830S's single-slot design limits on-board storage to 6TB, though its simultaneous playback specification—up to 32 channels (local 8, remote 8 per user across 3 remote users)—suggests it is optimized for networked rather than local-storage-centric architectures.
What are the differences in physical connectivity, power, and operating environment between the two units?
The QRN-830S includes a built-in 8-port PoE switch (8× RJ-45, 10/100 Mbps) with a 65W PoE budget and a separate 1 Gbps LAN/WAN port, powered at 54VDC/1.55A with a maximum draw of 84W including PoE. It operates from 0°C to +40°C at 20–85% RH, weighs 1.32 kg, and measures 300×47.6×238.9 mm in a 1U black metal chassis.
The HRX-835A-6TB lists PoE++ (802.3bt) support, an IK10 impact rating, and an IP66/NEMA 4X environmental rating—specifications that suggest suitability for harsher or semi-exposed installations. However, the provided specs do not state an operating temperature range, exact power consumption, chassis dimensions, or weight for the HRX-835A-6TB, so a direct numerical comparison on those points is not possible.
The QRN-830S provides 4K HDMI output at 3840×2160 (30Hz) with flexible multi-screen layouts (1/2H/2V/3V/4/6/8/9 screens). A corresponding local display specification for the HRX-835A-6TB is not present in the supplied data.
Which recorder offers broader integration, analytics, and remote management capabilities?
The QRN-830S carries a detailed network feature set: IPv4/IPv6, RTSP, SNMP, ONVIF Profile-S, SUNAPI (server and client), 802.1x port security, device certificate authentication via Hanwha Techwin Root CA, signed firmware, IP address filtering, and a 100,000-entry system and event log. Remote access supports up to 10 live unicast users, 20 multicast users, and 3 concurrent search users. N+1 failover and ARB (Automatic Recovery Backup) redundancy are specified. Fisheye dewarping is available via CMS, and PTZ preset capacity is listed at 300 presets.
The HRX-835A-6TB specifies ONVIF compliance, Deep Learning (DLPU)-based analytics, and People Counting—capabilities not listed for the QRN-830S in the provided data. Two-way audio is confirmed for both units; the HRX-835A-6TB lists 8-channel audio input and 1-channel output from its dedicated specs, while the QRN-830S specifies 8-channel network audio input/output with G.711, G.726, and AAC (16/48 kHz) compression formats.
The QRN-830S supports Windows 10 and macOS 11 web viewers (Chrome, Edge, Safari), iOS and Android mobile apps, P2P QR-code setup, and SUNAPI integration. Camera-level configuration items—bitrate, GOP, MD polygons, WDR, SSNR, DIS, and hallway view—are accessible from the NVR GUI. Equivalent remote management depth for the HRX-835A-6TB is not detailed in the supplied specifications.
Which should you choose: the HRX-835A-6TB or the QRN-830S?
Our take: The HRX-835A-6TB is the stronger choice when a site has existing analog cameras (AHD/HDTVI/HDCVI/CVBS) that must be retained alongside new IP cameras, or when storage growth beyond 6TB is required—its four SATA slots expand to 24TB versus the QRN-830S's single-slot 6TB ceiling. It also adds DLPU-based analytics and People Counting not listed for the QRN-830S. Conversely, the QRN-830S is the better fit for all-IP deployments: its built-in 8-port PoE switch (65W budget) eliminates a separate switch, its 4K HDMI output (3840×2160) exceeds any display spec provided for the DVR, and its N+1 failover, ARB redundancy, 802.1x security, signed firmware, and SUNAPI ecosystem make it the more network-mature platform. Choose the HRX-835A-6TB for hybrid analog/IP migrations with multi-TB growth needs; choose the QRN-830S for greenfield IP-only installations prioritizing network resilience and integrated camera power.

Can the HRX-835A-6TB or QRN-830S use my existing analog CCTV cameras?
Only the HRX-835A-6TB supports analog cameras. It accepts AHD, HDTVI, HDCVI, and CVBS signals across its 8 analog channels. The QRN-830S is a pure IP NVR and has no analog inputs; all cameras must connect over the network.
Which recorder gives me more storage room to grow?
The HRX-835A-6TB ships with 6TB installed and has four SATA slots expandable to 24TB total. The QRN-830S has a single SATA slot with a stated maximum of 6TB and no documented expansion path beyond that limit.
Is the HRX-835A-6TB or QRN-830S better suited for a fully IP camera system with remote monitoring?
The QRN-830S is purpose-built for that use case. It includes a built-in 8-port PoE switch (65W budget), supports up to 10 concurrent live unicast remote users and 20 multicast users, offers N+1 failover and ARB redundancy, and integrates with Hanwha's SUNAPI ecosystem. The HRX-835A-6TB's remote management depth is not fully detailed in the available specifications.
