About the Dahua XVR1B04-I
The Dahua XVR1B04-I is a small-channel NVR aimed at home, shop-front and small-office sites — the channel count caps the project naturally at a domestic-scale install. On-board storage tops out in single-digit TB — suitable for short retention windows (one to two weeks) at moderate channel counts. Plan an external NAS or eSATA expansion if the privacy policy or insurance contract requires longer retention. A single rack-unit slim chassis keeps the install footprint minimal and leaves headroom in the cabinet for a PoE switch, UPS and patch panel above it. 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
Residential & home installations
With 4 channels and 1-bay storage, the XVR1B04-I fits the typical home or villa install — front door, garage, garden, driveway. Single-disk recording at SMB bitrates covers 2-4 weeks of retention.
Strengths
- •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
- •Hybrid HD-CVI/AHD/TVI inputs let legacy analog cameras share the recorder with new IP cameras — useful for staged retrofits
- •Compact chassis fits in a half-height comms cabinet or office bench
Considerations
- •No built-in PoE — budget for a separate managed PoE switch with appropriate per-port wattage for the planned cameras
- •Single HDD bay means no RAID protection — schedule regular backups or pair with a secondary NVR/NAS for redundancy
- •Channel count caps install at small-site scale — verify the camera plan does not push past the channel limit during phased expansion
- •No RAID support — single-disk failure means losing all footage on that disk; plan retention policy accordingly
Storage planning
Running all 4 channels at the industry-typical 4 Mbps/channel H.265 CBR (15 fps, 4 MP scene complexity), the XVR1B04-I produces roughly 169 GB of footage per day — about 1181 GB/week, 5063 GB/month, and 15188 GB across a 90-day retention window. Fully populated with 1× 6 TB drives the unit holds 6 TB raw — enough for roughly 1.2× 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%.
Installation tips for the XVR1B04-I
Install in a standard 19-inch rack cabinet on supported rack rails; allow at least 1U of clearance above and below the 1U for airflow and HDD-bay servicing.
Plan storage at roughly 169 GB/day (≈5063 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.
Schedule weekly off-site backups (NAS, cloud, or sister NVR) since the single-bay design has no internal redundancy — a failed disk loses the entire archive.
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.
Power & rack
Power draw sits at roughly 35 W idle and around 35 W under full load (1-bay HDD activity). That dissipates approximately 119 BTU/hour of heat into the rack — size the comms-cabinet ventilation accordingly. Allow 1U 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 5-7 h of labour to commission the Dahua XVR1B04-I (approximately €225-€315 excluding hardware), broken down as physical install, HDD population, 4-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 XVR1B04-I record?
Up to 4 IP camera channels per chassis. The ingest bandwidth ceiling is not declared in the datasheet — confirm with the vendor before specifying high-bitrate (4K, 12 MP) cameras across all channels.
Does the Dahua XVR1B04-I 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 XVR1B04-I need for 30-day recording?
At the industry-typical 4 Mbps per channel H.265 CBR (15 fps, 4 MP scene), all 4 channels recording continuously for 30 days produces approximately 5063 GB (4.9 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 XVR1B04-I?
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 6 TB per bay across 1 bays = up to 6 TB raw capacity; populate matched pairs/sets if planning RAID.
Does the Dahua XVR1B04-I 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 XVR1B04-I need?
Plan for 35 W idle and ~35 W under full load, dissipating roughly 119 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 XVR1B04-I suitable for evidentiary recording?
Depends on the retention and chain-of-custody policy. The 1-bay chassis is single-disk only; for evidentiary recording, pair with a secondary NVR or NAS for redundancy. On the export side, ensure footage is hashed and timestamped before transfer to investigators.
