Hikvision DS-7604NI-Q1/4P-2TB 4-Channel 4K NVR with PoE

Hikvision DS-7604NI-Q1/4P-2TB 4-Channel 12MP Network Video Recorder

The Hikvision DS-7604NI-Q1/4P-2TB is a compact network video recorder engineered for deployments where physical space is constrained and infrastructure simplicity matters. This 4-channel unit records all four channels simultaneously at 12MP (4K) resolution and 30fps, making it suitable for retail loss-prevention, small office and warehouse surveillance, and branch locations where forensic detail—zooming to read a license plate or identify a face after an incident—is the primary requirement.

Key Features

• 12MP (4K) Multi-Channel Recording: Records 4 channels at 12MP (4096 × 2160 or 3840 × 2160) and 30fps simultaneously. This resolution density matters in retail and warehouse incident investigation; the megapixel count delivers the margin you need to crop and zoom into recorded video without losing critical detail. Mixed-resolution streams are also supported—8MP, 6MP, 5MP, 4MP, 3MP, 1080p, 720p, and CIF—so you can integrate older cameras without downsampling the newer 4K feeds.
• H.265+ Codec Reduces Storage Overhead: H.265+ compression cuts storage consumption roughly 50–70% compared to standard H.264 while preserving image quality. On the pre-installed 2TB HDD, this translates to 2–3x longer retention before you need to archive or add a second disk. A real factor when running continuous 24/7 recording across four 12MP channels; H.265+ cuts recurring storage costs and delays the need for expansion.
• Integrated 4-Port PoE Switch Simplifies Cabling: Built-in Power over Ethernet eliminates the need for a separate PoE injector or managed switch for your first four cameras. Each port supports IEEE 802.3af/at, delivering up to 30W per port—sufficient for most compact turret and dome IP cameras. This reduces Bill of Materials, cuts field cabling labor, and leaves your main network switch unloaded for other infrastructure traffic.
• Pre-Installed 2TB HDD with Expansion Path: Ships ready to record immediately; no drive installation needed. Supports expansion to 8TB per disk via dual SATA slots, so you can double capacity without replacing the original drive. If redundancy is required, RAID configurations are supported, enabling hot-swap failover for mission-critical locations.
• Flexible Recording Modes Reduce Operational Overhead: Continuous, motion-triggered, and scheduled recording modes adapt to site requirements. Motion-triggered recording cuts storage wear and simplifies forensic log review; scheduled modes let you record only during business hours or high-risk periods, further extending retention on fixed capacity.
• Dual Simultaneous Video Outputs for Multi-Monitor Setups: HDMI and VGA outputs can drive displays simultaneously at 4K, 2K, 1080p, and legacy resolutions. This allows a 4K monitor to display live view and playback in the SOC while a wall-mounted secondary display shows continuous patrol feeds—all without frame-rate degradation or output switching delays.
• Decoding Capacity Supports Forensic Playback Without Live-Recording Interruption: The unit can decode 1 channel at 8MP or up to 5 channels at 1080p simultaneously at 30fps. This means you can play back recorded footage for incident review while all four channels continue recording in real time—no operational pause during investigation.
• Two-Way Audio via RCA I/O: Supports G.711, G.722, and G.726 codecs for voice communication through connected microphones and speakers. Practical for retail intercom announcements or warehouse expediting without deploying a separate PA system.
• Remote Access and Network Scalability: Supports up to 32 simultaneous remote connections over IPv4/IPv6 via RTSP, SADP, SNMP, and UPnP protocols. The single 10/100 Mbps Ethernet interface handles 40 Mbps incoming and 80 Mbps outgoing bandwidth—adequate for mobile app monitoring and secondary remote site access without saturating your WAN link.
• Minimal Footprint and Power Draw: Dimensions of 320 × 240 × 48mm (12.6" × 9.4" × 1.9") and sub-kilogram weight allow mounting on shelves, inside AV cabinets, or behind existing rack equipment. Power draw is just 10W without HDD activity when PoE is disabled, rising to a maximum of 50W with PoE active and HDD spinning—low enough that you can often deploy on building UPS systems without additional power conditioning.
• Operating Environment Rated -10°C to +55°C: Handles most indoor installations and non-extreme outdoor shelters. Verify against your site's local climate if deploying in unheated storage or outdoor equipment closets; extreme cold or heat requires thermal management or shelter relocation.

Integration and Compatibility

The DS-7604NI-Q1/4P-2TB integrates with any ONVIF-compliant network video recorder ecosystem and supports standard IP cameras from Hikvision and other vendors. The single 10/100 Mbps Ethernet port handles both incoming camera streams and outgoing remote access; in bandwidth-constrained environments, confirm your upstream WAN capacity before deploying more than two simultaneous remote sessions. For sites with 32+ remote connections, consider dedicated bandwidth or a secondary WAN uplink.

Frequently Asked Questions

Q: Can I expand the storage beyond 8TB per disk?

A: The DS-7604NI-Q1/4P-2TB supports SATA drives up to 8TB per slot. Larger drives may be supported via future firmware updates, but you should verify compatibility with the manufacturer before purchasing a 10TB or larger drive for this model.

Q: Does the PoE switch port support high-power cameras like PTZ domes?

A: Each port delivers a maximum of 30W via IEEE 802.3af/at. Most compact fixed-dome and turret cameras (4–12W) will work reliably. High-power PTZ domes (60–95W) require a separate PoE+ or PoE++ injector or managed switch, not the integrated switch on this unit.

Q: What is the maximum bandwidth required for remote viewing?

A: The unit supports up to 32 remote connections with a typical bandwidth requirement of 2–8 Mbps per stream depending on resolution and frame rate. The unit's 80 Mbps outgoing bandwidth supports roughly 10–40 concurrent remote streams before saturation; in bandwidth-constrained WAN environments, use selective stream profiles (1080p or lower) to stay within your upstream limit.

Q: Does the unit support RAID or disk redundancy?

A: Yes. The dual SATA interface supports RAID 1 (mirrored) configurations for automatic failover. If one disk fails, the mirror continues recording without manual intervention. RAID setup is configured via the web interface or local display.

Q: What codec should I use for 24/7 continuous recording to minimize storage?

A: H.265+ delivers the best compression ratio (50–70% smaller than H.264) while maintaining image quality. If you need maximum compatibility with older VMS platforms or third-party software, fall back to H.264. MJPEG is useful only for high-motion scenes where codec efficiency matters less than CPU overhead.

Q: Is the DS-7604NI-Q1/4P-2TB suitable for outdoor deployment?

A: The operating temperature range (-10°C to +55°C) covers most non-extreme outdoor shelter. IP rating is not specified; treat this as an indoor or sheltered cabinet device. If you need true outdoor weatherproofing (rain, dust, extreme cold), deploy the NVR indoors and run camera cabling to exterior locations.

James Everett

The DS-7604NI-Q1/4P-2TB is a practical workhorse for retail and small-warehouse deployments where you need all four channels at native 12MP resolution without the overhead of a larger, multi-bay NVR chassis. The integrated PoE switch is the real differentiator here—it eliminates a separate switch from your Bill of Materials and one less device to power and manage. H.265+ compression on all four simultaneous 12MP streams is what makes 24/7 recording viable on the 2TB factory drive; without it, you'd be adding an expansion disk within weeks.

Technical Highlights:

• H.265+ on All Channels Simultaneously: You get 50–70% storage savings versus H.264 across all four channels at 30fps, not just one. On 2TB, expect 2–3 weeks of continuous 4K recording before you need to expand or archive. That's meaningful in retail incident response—you're not forced to buy a second 8TB drive immediately.
• Integrated 4-Port PoE at 30W per Port: Enough for your first four fixed-dome or turret cameras without a separate injector. Once you hit five cameras, you'll need to move to PoE+ or a managed switch—plan accordingly if you anticipate growth beyond four inputs.
• Decoding Isolation from Live Recording: Playback at 8MP or 5× 1080p simultaneous doesn't steal CPU cycles from recording. This matters in security operations—you can forensically review footage while four fresh channels keep rolling. No recording gaps during incident investigation.
• Compact Footprint, 10W Idle: At just 320mm × 240mm × 48mm and under 2.3 lbs, it fits on a shelf or inside a cabinet without ventilation fuss. Even with PoE active and an HDD spinning, max draw is 50W—low enough for small UPS systems or low-power installations.

Deployment Considerations:

• Four Channels Is the Hard Ceiling: This is not scalable. If you anticipate adding a fifth camera in six months, a larger 8-channel unit will save you a second deployment pass. Budget for it now rather than retrofit later.
• PoE Port Limitation for PTZ: If any of your four cameras are motorized PTZ domes (60–95W), the integrated switch ports will fail them. Those cameras need a separate PoE+ switch and injector—or stick to fixed-dome cameras and use the integrated switch for simplicity.
• Single 10/100 Mbps WAN Link: 32 remote users is a spec ceiling, not a typical number. In practice, expect 10–15 concurrent mobile/remote sessions before you hit saturation. If your remote user base is larger, consider a dedicated edge device or second NVR at a branch location instead of overloading this one.
• Disk Expansion Not Automatic: If you spec H.264 instead of H.265+ to save licensing or for legacy VMS compatibility, you will need an 8TB expansion disk within 1–2 weeks on continuous 24/7 recording. Use H.265+ by default unless you have a specific codec compatibility requirement.

Position this unit for retail stores, small office parks, or warehouse perimeter surveillance where you need 4K detail, PoE simplicity, and tight form factor—not scalability. It's also a solid secondary NVR for branch redundancy in larger deployments where the primary site runs a larger 16–32 channel recorder.
