Hikvision DS-7604NI-Q1/4P 4-Channel 12MP Network Video Recorder
The Hikvision DS-7604NI-Q1/4P is a compact, enterprise-grade 4-channel network video recorder engineered for organizations deploying small-to-medium surveillance infrastructure without sacrificing recording quality or operational flexibility. At under 1 kg and measuring just 320 × 240 × 48 mm, this unit fits into space-constrained branch offices, retail locations, and edge deployments where traditional larger network video recorders create installation headaches. The DS-7604NI-Q1/4P (often searched as DS 7604NI Q1/4P) consolidates a complete recording and switching backbone in a single enclosure: 4-channel video input, integrated 4-port PoE power delivery, H.265+ compression, dual video output (HDMI and VGA), and flexible storage scaling up to 8 TB per drive. This consolidation matters in cost-sensitive deployments — one less switch to buy, configure, and power means faster installation and lower bill-of-materials.
Key Features
- 4K (12MP) Recording Capacity: Records all four channels simultaneously at 12MP and 30 fps, delivering the pixel density needed for license plate reads, facial identification, and product shelf auditing. At this resolution, a single 8 TB drive stores roughly 30+ days of continuous 4-channel footage depending on motion settings and compression efficiency — a meaningful cost-per-day-of-retention figure for compliance-heavy deployments like retail or warehousing.
- H.265+ Compression: Cuts bandwidth and storage requirements by 40–60% versus H.264 depending on scene complexity and motion density. On a 40 Mbps incoming limit (the NVR's Ethernet constraint), this codec matters — you can reliably record 4 cameras at high resolution without the buffer drops that plague standard H.264 setups under similar constraints.
- Integrated 4-Port PoE Switch (802.3af/at): Powers four cameras directly from the unit, eliminating the need for a separate PoE injector or switch port reservation. Total power draw (NVR plus fully loaded PoE ports) stays under 50W at 48VDC, meaning no circuit-breaker strain at installation. This is especially valuable in retrofit scenarios where electrical infrastructure is already tight or where a dedicated PoE switch cannot be justified.
- Dual Video Output (HDMI + VGA): Run a 4K monitor on HDMI for detailed playback while simultaneously displaying a multi-resolution live view on a VGA monitor elsewhere in the facility. Both outputs are independent — useful for security operations centers that need simultaneous different-resolution feeds without investing in a separate display matrix or expensive video distribution hardware.
- Flexible Storage Scaling: Single SATA slot supports drives up to 8 TB. For a 4-channel 12MP setup with motion-adaptive recording, anticipate 2–5 TB per week depending on activity level, meaning one drive covers 2–4 weeks of compliance-grade retention. RAID or redundancy is not built-in — plan backup and archival strategy separately to meet your retention policy.
- Multi-Codec Playback: Decodes H.265+, H.265, H.264+, and H.264 streams natively, so mixed-codec camera fleets (legacy and new hardware) work without transcoding delays. Local playback and export remain responsive even with older stream formats in the database, reducing operational friction when integrating with existing Hikvision IP cameras or third-party ONVIF-compliant devices.
- Remote Access and Built-in Analytics: Supports 32 concurrent remote connections via TCP/IP, RTSP, HTTP/HTTPS, and DDNS, allowing mobile apps and web dashboards without mandatory VPN complexity (though VPN is recommended for production security). Built-in 1-channel or 4-channel human/vehicle detection analytics reduce false alerts in retail and parking environments without requiring external compute or edge intelligence hardware.
- Mono Audio Support: Two-way audio capability via RCA connectors using G.711, G.722, and G.726 codecs. Suitable for intercom scenarios at reception or gate monitoring, though audio quality is narrow-band (not high-fidelity) — adequate for voice confirmation, not music or detailed environmental audio.
Integration and Operating Conditions
The DS-7604NI-Q1/4P operates from -10°C to +55°C and tolerates 10–90% humidity without active cooling, making it suitable for unheated storage rooms, retail back-of-house, and temperature-moderated warehouse zones. No fan means silent operation and no maintenance burden from dust accumulation — a real advantage in clean-room or noise-sensitive retail environments.
Network connectivity is straightforward: a single 10/100 Mbps Ethernet port handles both inbound management traffic and remote client connections. Four-port PoE switch on the same unit means you can wire all four cameras directly into the NVR without requiring an external PoE injector, simplifying cable runs in compact installations. The unit does not include built-in redundancy (no mirroring or RAID support) — if storage failure is a risk, plan for external NAS backup or a second recording instance.
Video export supports AVI and MP4 formats, making clips usable in standard video players and evidence-management workflows without proprietary software. ONVIF support ensures compatibility with third-party video management systems (VMS) beyond Hikvision's own ecosystem, should you need multi-vendor integration.
Deployment Considerations
This recorder is purpose-built for edge and branch deployments where one 4-port PoE switch plus local storage satisfy the compliance and monitoring requirement. If you need more than 4 cameras, more than 8 TB of storage, or RAID protection, step up to the higher-capacity models in the Hikvision NVR lineup. The single Ethernet port is a constraint in high-bandwidth scenarios — if you have 4 cameras streaming simultaneously at maximum bitrate, saturation is possible; in practice, H.265+ and motion-adaptive recording prevent this in most deployments.
Power it from a 48VDC supply (included or sourced separately) or via an external AC/DC converter. Do not exceed the unit's PoE power budget of 50W if you attach high-power cameras — verify your camera power draw against the 802.3af/at specification before ordering.
When to Choose a Different Model
If you need more than 4 channels, consider an 8-channel or 16-channel variant in the same Hikvision family. If redundancy and RAID protection are non-negotiable, look for higher-end NVRs that support disk mirroring. If you require gigabit Ethernet or higher throughput, step up to models with 10/100/1000 Mbps ports. If your environment is outdoor or requires vandal-resistant housing, verify that this compact form factor meets your physical security requirements — it is primarily an indoor unit.
Frequently Asked Questions
Q: Can I add a second hard drive to the DS-7604NI-Q1/4P?
A: No. The unit has a single SATA slot. You cannot configure RAID or add redundant storage internally. Plan for external backup via NAS or cloud archival if retention beyond one drive's capacity is required.
Q: Does this NVR support ONVIF cameras from other manufacturers?
A: Yes. The DS-7604NI-Q1/4P is ONVIF-compatible and can accept RTSP streams from third-party IP cameras. However, verify that your non-Hikvision cameras output H.264 or H.265 streams — older MJPEG-only cameras may work but will consume more bandwidth and storage.
Q: What's the maximum recording duration on a single 8 TB drive?
A: Approximately 30+ days of continuous 4-channel 12MP recording, depending on motion settings, scene complexity, and H.265+ compression efficiency. Motion-adaptive recording extends this significantly — typical deployments see 4–8 weeks of retention per 8 TB drive.
Q: Can I access recordings remotely via a mobile app?
A: Yes. The NVR supports up to 32 concurrent remote connections via RTSP, HTTP/HTTPS, and DDNS. Hikvision's mobile apps (Hik-Connect) allow remote live view and playback, though for production deployments, a VPN or corporate network integration is recommended.
Q: What power supply do I need?
A: The unit requires 48VDC at 1.35A maximum (≤50W with all four PoE ports active). A compatible external 48VDC power supply is required — verify it is sourced separately or confirm inclusion with your order.
Q: Is this NVR suitable for outdoor mounting?
A: The DS-7604NI-Q1/4P is rated for -10°C to +55°C operation, but it is not designed as an outdoor enclosure. It lacks IP66 rating or vandal-proof housing. Install it indoors — in a closet, rack, or back-of-house area. For outdoor edge recording, consider a weather-sealed variant if available in the Hikvision catalog.

The DS-7604NI-Q1/4P is a workhorse for small-footprint deployments where you need simultaneous 4-channel 12MP recording without the power and space overhead of larger NVRs. The integrated 4-port PoE switch is the real value driver here — it eliminates a separate network appliance and cuts installation time significantly in branch offices or retail environments.
Technical Highlights:
- H.265+ Compression: Delivers 40–60% bandwidth and storage savings versus H.264, critical when you're constrained to a single 10/100 Mbps Ethernet port. Four 12MP cameras at 30 fps would overwhelm H.264 on this link; H.265+ makes it workable.
- Integrated PoE (802.3af/at): Four cameras powered from the NVR itself, under 50W total system draw. No separate PoE switch to provision, no additional power outlet required at installation. This matters in retrofit scenarios where existing electrical infrastructure cannot support another 60W appliance.
- 8 TB Storage Ceiling: Single SATA slot, single 8 TB drive yields approximately 30 days of continuous 4-channel 12MP recording. Motion-adaptive mode extends this to 4–8 weeks per drive. Plan for weekly or monthly archive-to-NAS if compliance retention exceeds this window.
Deployment Considerations:
- Single 10/100 Mbps Ethernet port is a genuine bottleneck if all four cameras stream at maximum bitrate simultaneously. H.265+ and motion-based recording are essential to avoid saturation; confirm your camera bitrate specs before committing.
- No RAID or disk mirroring. If a drive fails, recordings are lost. For mission-critical sites, plan external backup (NAS replication or cloud archival) as a separate step.
- Indoor-only operating envelope (-10°C to +55°C, no IP rating). Do not mount this in outdoor housings or unheated spaces.
The DS-7604NI-Q1/4P is purpose-built for retail chains, small offices, or warehouse branch locations where four cameras and local 30–90 day retention satisfy the compliance requirement. If your site needs more cameras or RAID redundancy, this is not the right choice — step up to an 8-channel or higher-capacity model. For greenfield edge recording without the operational overhead of a full NVR room, this is exactly the fit you're looking for.
