Hikvision DS-7604NI-Q1/4P-1TB 4-Channel 4K Network Video Recorder

The Hikvision DS-7604NI-Q1/4P-1TB is a compact 4-channel network video recorder engineered for small-to-medium business and enterprise branch deployments where installation simplicity and cost efficiency matter. This unit combines 12MP (4K) recording capability with integrated PoE power distribution and H.265+ compression—eliminating the need for a separate PoE injector or external power supply and cutting storage consumption roughly in half compared to H.264. The pre-installed 1TB hard drive is ready for immediate deployment, with expandable storage up to 8TB per disk for longer retention periods.

Key Features

• 4K Recording at 12MP (4-channel simultaneous): Captures detail-rich footage at 30fps across all four channels simultaneously. This resolution provides readable facial and license plate detail at distance—critical for forensic analysis and incident review.
• H.265+ Compression: Delivers 40–70% file size reduction versus H.264 depending on scene complexity. For 24/7 multi-camera deployments, this translates to meaningfully lower storage costs and reduced WAN bandwidth when transmitting footage to centralized monitoring sites.
• Integrated 4-Port PoE Switch (802.3at): Built-in PoE power distribution eliminates the expense and floor-space overhead of a separate injector. Supplies power and Ethernet to four PoE-compatible IP cameras over standard Cat5e/Cat6 cabling.
• Pre-installed 1TB HDD: Ships ready to deploy. Storage capacity supports 24/7 recording at 12MP across all four channels for approximately 20–40 days depending on scene activity and compression efficiency—adequate for typical SMB incident retention policies.
• Flexible Recording Modes: Continuous, motion-triggered, and scheduled recording allow fine-tuning of storage usage and system load based on facility risk profile and operational hours.
• Dual Video Outputs (HDMI + VGA): Supports simultaneous 4K display on a primary monitor and extended monitoring on a secondary display—useful for command centers or distributed review workflows.
• 4-Channel Synchronous Playback: Review all four streams in real time during incident investigation, reducing time spent correlating separate timeline views.
• Remote Access & Mobile App: Live viewing, playback, and configuration via Hikvision app or web browser. Supports up to 32 concurrent remote connections—practical for distributed teams or after-hours access.
• Human/Vehicle Detection: Built-in intelligent algorithms reduce false alerts during playback search and event review, accelerating investigation workflows on systems with steady-state motion.
• Two-Way Audio (RCA): Integrated audio I/O enables real-time voice communication at the recording site—useful for retail or facility access control scenarios.

Integration & Compatibility

The DS-7604NI-Q1/4P accepts any ONVIF-compliant IP camera but pairs naturally with Hikvision IP cameras for streamlined management and feature parity. The single 10/100 Mbps Ethernet port supports TCP/IP, DHCP, IPv4/IPv6, DDNS, NTP, RTSP, HTTPS, and iSCSI protocols—essential for enterprise network integration. Operating temperature range of –10 to +55°C (14 to 131°F) accommodates small server closets and unheated outdoor shelters typical in warehouse or retail branch environments. When selecting this unit for a multi-site deployment, consult your network video recorder architecture guide to validate storage retention and bandwidth capacity across your PoE switch infrastructure.

The unit's ultra-low power consumption (≤10W without HDD) and compact 320 × 240 × 48 mm profile (1.9 inches tall, under 1 kg) make it suitable for wall-mount, shelf, or rackmount scenarios where space and thermal load are constrained. FCC Part 15 and CE (EN 55032, EN 61000-3, EN 50130-4) certifications confirm compliance with North American and European electromagnetic and safety standards.

When to Choose a Different Model

If your cameras exceed 12MP resolution or you require analytics (people counting, abandoned object detection) at the recorder level, evaluate higher-capacity variants in the DS-76xx series. If you need 8+ channels, consider an 8-channel or 16-channel recorder instead. For deployments requiring local alarm I/O, RAID redundancy, or hot-swappable drive bays, consult a higher-tier commercial platform.

Frequently Asked Questions

Q: What is the maximum storage capacity of the DS-7604NI-Q1/4P-1TB?

A: The unit supports one internal 3.5-inch or 2.5-inch SATA hard drive up to 8TB. The pre-installed 1TB drive can be replaced or the NVR expanded with larger capacity drives depending on your retention policy and budget.

Q: Does the DS-7604NI-Q1/4P-1TB support ONVIF cameras from other manufacturers?

A: Yes. The recorder accepts any ONVIF-compliant IP camera. However, advanced features (edge AI, automatic calibration, firmware management) may be limited to Hikvision cameras and may require integration with a Hikvision management platform.

Q: Can I use PoE cameras that draw more than 30W per port?

A: No. The integrated 4-port PoE switch is rated 802.3at (30W per port, ~95W total). High-power cameras (40W+) require a separate PoE++ injector or switch. Verify camera power budget before purchase.

Q: What is the bandwidth requirement for remote viewing of all four channels at 12MP?

A: The recorder supports 80 Mbps outgoing bandwidth capacity. Actual WAN bandwidth depends on encoding bitrate, frame rate, and H.265+ efficiency. Plan for 15–30 Mbps per channel for reliable remote access.

Q: Does the DS-7604NI-Q1/4P-1TB work with Milestone XProtect or other third-party VMS platforms?

A: The unit operates as a standalone recorder with ONVIF support. Third-party VMS integration is possible via RTSP and web API if supported by your VMS vendor. For seamless integration and advanced features, Hikvision recommends using the native HiLook or iVMS management suite.

Q: What happens to recorded footage if power is lost?

A: The HDD contains all footage. Upon power restoration, the recorder resumes recording automatically. For uninterrupted recording during brief outages, integrate an uninterruptible power supply (UPS) rated for the unit's low 10W idle power draw.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-7604NI-Q1/4P-1TB balances cost and operational efficiency effectively for distributed surveillance across retail chains, small office parks, and warehouse networks. The integrated 4-port PoE switch eliminates a separate hardware dependency—one less failure point and one less power budget to manage on your core switch. H.265+ compression genuinely reduces storage overhead; on a unit recording 24/7, you'll see meaningful cost savings across 10+ recorders in a branch deployment.

Technical Highlights:

• H.265+ Compression: 40–70% smaller files than H.264 translate directly to lower NAS/SAN costs when centralizing footage from multiple branch locations over WAN links.
• Integrated 802.3at PoE (95W total): Eliminates the need for a standalone injector or injector pair; reduces cabinet clutter and power consumption on core infrastructure. Watch the per-port budget: 30W maximum per camera, so confirm your camera power draw before deployment.
• 12MP 4-Channel Simultaneous: Supports readable forensics across four zones at once. Decoding capability is single 8MP at 30fps or five 1080p streams in parallel—adequate for multi-monitor playback in SOC or investigative workflows.
• Compact Form Factor (<1 kg, 1.9" profile): Wall-mount or shelf-deploy in server closets, cabinet corners, or small retail back offices where space is tight. Low 10W idle draw means thermal load is negligible even in unventilated shelters.

Deployment Considerations:

• Network connectivity is single 10/100 Mbps Ethernet—adequate for four-channel 12MP streaming but not a bottleneck if you plan camera mix-and-match. Validate WAN bandwidth: 80 Mbps egress capacity supports roughly 2–3 concurrent remote 12MP streams over typical broadband. Plan for saturation if multiple sites initiate live viewing simultaneously.
• Storage: 1TB at 24/7 recording delivers ~20–40 days retention depending on scene complexity and H.265+ compression efficiency. If forensic storage beyond 60 days is required, evaluate an 4TB or 8TB swap-in HDD upfront rather than upgrading later.
• PoE power budget is firm: 95W total across four ports means you cannot stack multiple high-draw cameras. If you have high-speed dome or thermal cameras consuming 40W+ each, this recorder is not the platform—upgrade to a higher-power PoE switch or use a standalone injector.

Best positioned for retail multi-location surveillance, small office and warehouse networks, and educational or hospitality branch sites where IT overhead is minimal and pre-configured, single-unit deployments reduce commissioning risk. If you need centralized RAID, failover, or deep analytics at the recording layer, step up to an 8-channel or 16-channel unit in the commercial NVR tier.
