Product SKU: HV-HRX-1635
Product Overview
Upgrading or expanding a mixed-camera site becomes significantly more manageable with the Hanwha Vision HRX-1635, a 16-channel Pentabrid DVR designed to accept AHD, HDTVI, HDCVI, CVBS, and IP camera inputs from a single recorder. Rather than replacing existing analog infrastructure, this recorder allows installers to consolidate legacy analog cameras alongside newer IP cameras into one system, supporting up to 18 total channels depending on how many analog channels are active. Recording reaches up to 8MP resolution with H.265, H.264, and MJPEG codec options, while up to 8 SATA HDD bays accommodate drives up to 6TB each, giving sites serious long-term storage capacity. Coaxial control, 4 audio inputs, 16 alarm inputs, and 4 relay outputs extend the system well beyond basic recording. Remote access via P2P QR code connection links directly to the Wisenet Viewer and Wisenet Mobile app. The unit ships without a hard drive, so storage must be planned and purchased separately. NDAA and FCC compliant.
Key Capabilities
5-in-1 Pentabrid Input Compatibility
Accepts AHD, HDTVI, HDCVI, CVBS, and IP camera signals across 16 analog channels. Sites with existing analog cameras can integrate them directly without replacement, reducing upgrade costs and simplifying migration to higher-resolution cameras over time.
Flexible Channel Expansion to 18 Total
As analog channels are freed up, network camera slots expand accordingly, reaching a maximum of 18 total channels. This lets sites gradually shift toward full IP without needing a new recorder, protecting the hardware investment as the camera mix evolves.
High-Resolution Recording up to 8MP
Supports per-channel recording at 8MP (15fps), 5MP (20fps), 4MP (30fps), 2MP (30fps), and 1MP (30fps). Higher-resolution cameras capture finer detail across entrances, car parks, and loading areas without needing additional recorders.
Large-Capacity Storage Architecture
Eight SATA HDD bays each support drives up to 6TB, allowing a maximum raw storage of 48TB internally. Combined with a 128Mbps recording bandwidth, this supports continuous high-resolution recording across all channels for extended retention periods.
Coaxial Control and Alarm I/O
Coaxial control allows PTZ and camera settings to be managed over the existing coax cable without additional wiring. The 16 alarm inputs and 4 relay outputs support integration with door contacts, sirens, and access control hardware for a more coordinated security response.
P2P Remote Access and Dual Monitor Output
P2P QR code pairing connects the recorder to Wisenet Viewer and Wisenet Mobile without complex network configuration. HDMI and VGA outputs support dual monitor expand mode, with a separate spot monitor output for dedicated display at reception or a guard station.
Best For
- Mixed Analog and IP Deployments: Pentabrid input support lets sites run legacy analog cameras and newer IP cameras from a single recorder, avoiding the cost of a full camera refresh.
- Medium to Large Commercial Sites: 16 analog channels with expansion to 18 total suits warehouses, retail groups, schools, and multi-tenancy buildings where camera counts are high and coverage is distributed across zones.
- Long Retention Requirements: Eight HDD bays supporting up to 48TB of storage suits sites that need weeks of continuous footage retained for compliance, insurance, or incident review purposes.
- NDAA-Compliant Installations: Government facilities, defence-adjacent sites, and projects requiring NDAA compliance can deploy the HRX-1635 with confidence, as it carries both NDAA and FCC certification.
Why Choose the HV-HRX-1635
The HRX-1635 occupies a practical position in any upgrade project where replacing all existing cameras at once is not financially or logistically viable. Its 5-in-1 Pentabrid architecture handles AHD, HDTVI, HDCVI, CVBS, and IP signals simultaneously, which most single-format DVRs cannot. The 8 SATA bays with up to 6TB per drive give installers genuine flexibility in storage planning rather than forcing early compromises. Coaxial control removes the need for separate control cabling when managing PTZ cameras. The 16 alarm inputs and 4 relay outputs allow integration with external security hardware that a basic recorder would not support. H.265 compression keeps bandwidth manageable across all 16 channels at 128Mbps maximum. Available through Security Wholesalers, the HRX-1635 suits integrators and end-users who need a proven, NDAA-compliant recorder that works with what they already have while leaving clear room to expand.
Buyer Decision Tips
Storage Planning: The HRX-1635 ships with no HDD installed. Before deployment, calculate your required retention days based on channel count, resolution, and frame rate. At 2MP across 16 channels using H.265, a single 6TB drive covers only a limited window. For extended retention, plan for multiple drives early and purchase HDDs rated for surveillance use (CMR/PMR type), as SMR drives are not recommended for continuous multi-channel recording workloads.
Channel Count Trade-Off: The total of 18 channels is not fixed. The number of available network camera slots increases as analog channels are left unused. If all 16 analog inputs are occupied, only 2 IP channels are available. If you need more than 2 IP channels immediately, plan which analog cameras can be retired or consider how many analog inputs will remain in use before committing to a camera layout.

Ideal Use Cases
Legacy System Upgrades
Sites with existing CVBS, HDTVI, or AHD cameras can be consolidated into the HRX-1635 without replacing existing cabling or cameras. Pentabrid input support means the recorder adapts to what is already installed, not the other way around.
Warehouses and Distribution Centres
High camera counts, extended footage retention, and alarm integration with dock doors or perimeter sensors are all supported. The 16 alarm inputs and 4 relay outputs allow meaningful automation across large floor plans with multiple zones.
Retail Chains and Multi-Tenancy Buildings
The dual monitor output in expand mode lets operators view overview and detail layouts simultaneously. P2P remote access via the Wisenet Mobile app allows managers across multiple locations to check footage without on-site attendance.
Schools and Education Facilities
16 channels cover classrooms, corridors, car parks, and entry points from a single recorder. Audio input across 4 channels supports zones requiring audio monitoring, while the spot monitor output provides dedicated display at a reception or security desk.
Government and Compliance-Sensitive Sites
NDAA and FCC compliance makes the HRX-1635 suitable for government buildings, defence-adjacent facilities, and any project where the recorder supply chain must meet regulatory requirements. Compliance is confirmed, not assumed.
Choosing the Right Model
- Choose this model if: You are managing a site with a mix of analog and IP cameras across up to 16 channels, need serious storage headroom with up to 8 HDD bays, require alarm I/O for integration with third-party devices, or must meet NDAA compliance requirements.
- Choose a different model if: Your site has already moved entirely to IP cameras and you need higher channel counts or advanced analytics, in which case a dedicated NVR with more network channels and native AI processing would be a more appropriate fit. Similarly, if your site needs fewer than 8 channels, a smaller Pentabrid DVR would reduce unnecessary hardware overhead.
FAQs
- What does Pentabrid mean on the HRX-1635?
Pentabrid refers to the recorder’s ability to accept 5 different camera signal types on a single unit: AHD, HDTVI, HDCVI, CVBS (standard analog), and IP cameras. This means you are not locked into a single camera brand or technology, and you can run cameras from different manufacturers or eras on the same recorder simultaneously.
- How many total channels does the HRX-1635 support?
The recorder supports up to 18 total channels, but this is not a fixed split. The number of available IP channels depends on how many analog channels are actively in use. With all 16 analog inputs occupied, only 2 IP channels are available. As analog channels are decommissioned, IP channel capacity increases accordingly, up to a maximum of 18 total channels.
- Does the HRX-1635 come with a hard drive?
No. The HRX-1635 is supplied without any HDD installed. You need to purchase compatible SATA surveillance-grade hard drives separately. The recorder supports up to 8 drives at a maximum of 6TB per drive, giving a raw storage ceiling of 48TB. Surveillance-rated CMR/PMR drives are strongly recommended for continuous multi-channel recording.
- What resolution can the HRX-1635 record at?
The recorder supports per-channel recording at 8MP (15fps), 5MP (20fps), 4MP (30fps), 2MP (30fps), 1MP (30fps), and 960H or 720H at 30fps. The resolution recorded depends on the camera connected to each channel, so you can run different resolutions across channels within the same system.
- How does remote access work on the HRX-1635?
The recorder uses Hanwha’s P2P service, which allows you to scan a QR code displayed on the unit and connect directly to the Wisenet Viewer desktop application or the Wisenet Mobile app on a smartphone or tablet. This simplifies remote setup without requiring manual port forwarding or static IP configuration in most network environments.
- Is the HRX-1635 suitable for a wall-mounted guard station or reception desk?
Yes. The recorder provides both HDMI and VGA outputs in dual monitor expand mode, allowing a guard station or reception desk to display different camera views on 2 separate screens simultaneously. The dedicated spot monitor output adds a third display option, useful for a standalone overview or alarm trigger display at a control point.
- Is the HRX-1635 NDAA compliant?
Yes. The HRX-1635 carries confirmed NDAA and FCC compliance. This is relevant for any project supplying equipment to federal government facilities, defence-adjacent environments, or commercial clients whose procurement policies require NDAA-compliant hardware. Compliance documentation is available from Security Wholesalers upon request.
