About the Dahua NVR5864-XI/Pro
The Dahua NVR5864-XI/Pro is a 33-64 channel rack appliance built for commercial-scale CCTV — the channel headroom absorbs phased expansion without forcing a second unit. High-capacity HDD bay count carries 60-180 day retention without external storage at typical commercial-camera bitrates, and supports RAID protection so single-disk failure does not lose footage. At 2U the unit balances density and serviceability — hot-swap bays sit on the front panel within reach for HDD replacement without removing the chassis from the rack. No PoE ports are built into the recorder, so cameras connect through a separate PoE switch. That is the preferred architecture on professional installs because a dedicated managed switch gives finer VLAN control, larger PoE budgets, and easier replacement than an integrated switch tied to the NVR chassis.
Best use cases for this recorder
Campus, factory, logistics & critical infrastructure
At 64 channels per chassis, the unit consolidates what would otherwise be 2-4 mid-range NVRs into a single rack appliance. Useful where licensing per-chassis matters and where consolidating storage onto one RAID set simplifies forensic retrieval.
4K/8MP camera deployments
Native support for 32 MP per-channel recording matches it to current-generation 4K cameras — useful when the install plan calls for fewer-but-higher-resolution cameras (typical of perimeter, parking, and identification-focused layouts).
Long-retention archive & evidentiary recording
8 HDD bays at up to 20 TB each give the unit petabyte-class storage capacity, supporting 6-12 month retention windows mandated by some banking, retail-loss-prevention, and public-transport contracts.
Strengths
- •64-channel headroom absorbs phased expansion without forcing a second chassis
- •8 HDD bays support RAID protection for evidentiary recording
- •Smart H.265+ codec halves storage cost over H.265 at equivalent perceived quality
- •ONVIF compliance lets the unit record from third-party cameras, not just the same-brand catalog
- •512 Mbps ingest bandwidth supports the unit at full channel count at 4K resolution
Considerations
- •No built-in PoE — budget for a separate managed PoE switch with appropriate per-port wattage for the planned cameras
- •No RAID support — single-disk failure means losing all footage on that disk; plan retention policy accordingly
Storage planning
Running all 64 channels at the industry-typical 4 Mbps/channel H.265 CBR (15 fps, 4 MP scene complexity), the NVR5864-XI/Pro produces roughly 2700 GB of footage per day — about 18900 GB/week, 81000 GB/month, and 243000 GB across a 90-day retention window. Fully populated with 8× 20 TB drives the unit holds 160 TB raw — enough for roughly 2.0× the one-month archive at full bitrate before RAID overhead. These figures are deterministic — derived from your bitrate assumption, the channel count, and the calendar — not estimated from a marketing data sheet.
Estimates assume 4 Mbps per channel H.265 CBR continuous recording. Motion-only recording typically reduces storage by 40-70%.
Bandwidth headroom
Input (ingest)
Avg 8.0 Mbps per channel — enough for 4K H.265 at 4 Mbps/channel.
Output (playback)
Sets the ceiling for simultaneous remote playback streams to mobile and web clients.
Installation tips for the NVR5864-XI/Pro
Install in a standard 19-inch rack cabinet on supported rack rails; allow at least 1U of clearance above and below the 2U for airflow and HDD-bay servicing.
Plan storage at roughly 2700 GB/day (≈81000 GB/month) for continuous H.265 recording at 4 Mbps/channel — match HDD capacity to the longest retention window the privacy policy or insurance contract demands.
Pair with a managed PoE switch sized for the camera plan — choose 802.3at (≤30 W/port) for typical IR-equipped bullets, 802.3bt (≤60-90 W/port) when PTZ or heated housings are in scope.
Place the recorder on a dedicated VLAN with the cameras — separating CCTV traffic from office VLANs avoids broadcast storms degrading recording quality during busy network hours.
Power & rack
Power draw sits at roughly 70 W idle and around 70 W under full load (8-bay HDD activity). That dissipates approximately 239 BTU/hour of heat into the rack — size the comms-cabinet ventilation accordingly. Allow 2U of cabinet space for the chassis plus 1U of unobstructed airflow above and below; pair with a UPS sized for at least 15-minute hold-up so the recorder shuts down cleanly on mains failure.
Installer time & cost (rough estimate)
A typical EU integrator quotes 13-15 h of labour to commission the Dahua NVR5864-XI/Pro (approximately €585-€675 excluding hardware), broken down as physical install, HDD population, 64-channel discovery and IP/credential configuration, schedule + retention setup, motion / event rules per camera, mobile-app pairing, and a brief operator handover. Allow extra time for sites with non-standard network topology (multi-VLAN, multi-site bridges) or for migrations from a legacy DVR where camera streams must be re-addressed.
Indicative EU 2024-2025 pricing — actual quotes vary by region, network topology and migration scope. Excludes hardware, HDDs, transport, permits, and VAT.
Frequently asked questions
How many cameras can the Dahua NVR5864-XI/Pro record?
Up to 64 IP camera channels per chassis. Total ingest bandwidth is 512 Mbps, which sets the practical ceiling — running every channel at 4K (typically 8 Mbps each) requires 512 Mbps, so verify whether your camera plan fits inside the bandwidth budget.
Does the Dahua NVR5864-XI/Pro support third-party (ONVIF) cameras?
Yes — ONVIF Profile S/T support means the unit records from third-party cameras as well as the same-brand catalog. Most cameras supporting ONVIF 16.12 or newer plug-and-play; older firmware may require manual stream URL configuration in the NVR web UI.
How much storage does the Dahua NVR5864-XI/Pro need for 30-day recording?
At the industry-typical 4 Mbps per channel H.265 CBR (15 fps, 4 MP scene), all 64 channels recording continuously for 30 days produces approximately 81000 GB (79.1 TB) of footage. Motion-only or event-triggered recording typically cuts that by 40-70 % depending on scene activity. Plan HDD capacity for the longest retention window your privacy policy or insurance contract demands.
What HDDs are recommended for the Dahua NVR5864-XI/Pro?
Use surveillance-rated HDDs — WD Purple, Seagate SkyHawk, Toshiba S300, or equivalent. Desktop / consumer drives (WD Blue, Seagate Barracuda) are not validated for 24/7 write workloads and typically fail within 12-18 months in CCTV use. Max 20 TB per bay across 8 bays = up to 160 TB raw capacity; populate matched pairs/sets if planning RAID.
Does the Dahua NVR5864-XI/Pro need its own PoE switch?
Yes — the recorder has no built-in PoE, so cameras connect through a separate managed PoE switch. Size the switch's PoE budget for the planned cameras: 802.3at (≤30 W/port) handles typical IR-equipped bullets and domes; 802.3bt (≤60-90 W/port) is needed for PTZ and heated housings.
What power and cooling does the Dahua NVR5864-XI/Pro need?
Plan for 70 W idle and ~70 W under full load, dissipating roughly 239 BTU/hour into the rack or cupboard. Size the UPS for at least 15-minute hold-up so the unit can flush write buffers and shut down cleanly on mains failure — abrupt power loss is the leading cause of NVR file-system corruption in commercial installs.
Is the Dahua NVR5864-XI/Pro suitable for evidentiary recording?
Depends on the retention and chain-of-custody policy. The 8-bay chassis supports basic mirroring on the install side, but lacks declared RAID 5/6 parity — verify with the vendor whether RAID is supported in newer firmware On the export side, ensure footage is hashed and timestamped before transfer to investigators.
