Dahua DHI-NVR2104-I2 - 4 Channel NVR
The Dahua DHI-NVR2104-I2 is a 4 channel WizSense network video recorder in a 1U case with one hard drive bay. It records IP cameras from D1 up to 12MP, which makes it a fit for a small home or shop system.
Bandwidth is 80Mbps for incoming video and 80Mbps for recording. With AI switched off it can decode one 12MP camera, two 5MP cameras or up to six 1080p streams; with AI on, the figures drop to one 8MP, two 4MP or four 1080p. The single SATA bay takes a drive of up to 10TB.
The recorder runs face detection and recognition on 1 channel, perimeter protection on 1 channel and SMD Plus on all 4 channels. It has no PoE ports, so cameras need a PoE switch or their own power. HDMI (up to 4K) and VGA outputs run at the same time, and ONVIF Profile T, S and G allows third-party cameras.
Also listed as NVR2104-I2.

Works with
Hard drive options are listed on this page. The datasheet supports one SATA drive of up to 10 TB. Surveillance drives we stock include:
- Western Digital WD Purple WD10PURZ 1TB surveillance hard drive
- Toshiba S300 HDWT720UZSVA 2TB video streaming hard drive
- Western Digital WD Purple WD40PURZ 4TB surveillance hard drive
- Toshiba S300 HDWT740UZSVA 4TB video streaming hard drive
- Western Digital WD Purple WD82PURZ 8TB surveillance hard drive
Also suggested for a complete system:
- Dahua DH-PFS3005-4ET-60-V2 5 Port PoE Switch: powers the cameras, since the recorder has no PoE ports
- Dahua DH-IPC-HDW3849HP-AS-PV-0280B-PRO 8MP Eyeball: an 8MP camera; with AI on, the recorder decodes one 8MP stream at 30fps
Pairings are suggested on general compatibility (same brand, matching connection type and specification), not as tested combinations.
Other Dahua recorders in this range: DHI-NVR2104HS-I2 (4 channel, compact 1U), DHI-NVR2104-P-I2 (4 channel, 4 PoE ports), DHI-NVR2108-I2 (8 channel), DHI-NVR2116-I2 (16 channel).
Common questions
How many cameras can the DHI-NVR2104-I2 record?
It has 4 access channels and accepts IP camera resolutions up to 12MP. Bandwidth is 80 Mbps for access, 80 Mbps for storage and 60 Mbps for forwarding.
Does the DHI-NVR2104-I2 have PoE ports?
The Dahua datasheet lists no PoE ports for this model, so IP cameras need a PoE switch or their own power supply. If you want built-in PoE, see the DHI-NVR2104-P-I2 (4 channel, 4 PoE ports).
Can I order the NVR with a hard drive?
Yes. Use the Hard Drive option on this page to add a Western Digital WD Purple or Toshiba S300 surveillance drive to your order, giving you an NVR with hard drive, or select recorder only. The datasheet supports one SATA drive of up to 10 TB.
How much hard drive storage can it take?
It has 1 SATA port and supports up to 10 TB. Dahua notes that the maximum HDD capacity varies with environment temperature.
What does WizSense mean?
Dahua describes WizSense as a series of AI products and solutions that use an independent AI chip and a deep learning algorithm, focused on people and vehicles. Read our WizSense guide for more.
Do I need AI cameras for face detection or perimeter protection?
Not for the recorder functions. AI by NVR gives 1-channel face detection and recognition, 1-channel perimeter protection and 4-channel SMD Plus. The datasheet also lists AI by camera for compatible cameras.
Can it record third-party IP cameras?
Yes. Dahua lists third-party network camera access through ONVIF (profile T, S and G), CGI and SDK.
What monitor outputs does it have?
One HDMI output up to 4K and one VGA output, which can be used at the same time. Live view can be shown as 1 or 4 views.
Can I view the cameras on my phone?
Yes. Dahua lists mobile phone access on Android and iOS, and browser access through Chrome, Firefox or IE9 and later.
How is the recorder powered?
It runs from a 12V DC, 1.5A supply and uses 10W without a hard drive fitted.
