DAHUA DHI-NVR2104-I2 (4 CHANNELS, 12 MP) - IP VIDEO RECORDER
Description Dahua DHI-NVR21xx-I2
The most affordable entry ticket into Dahua's analytics lineup
Dahua's I2 series is a model range where face recognition and perimeter protection are already present at the base level, unlike the budget S3/H series, which has neither at all. DHI-NVR21xx-I2 is the smallest and most affordable model in this series, with just 4 channels — and that's exactly why it's interesting: analytics that would cost a significant premium with other manufacturers is available here right at the entry point.
The lightest model in its series — just 0.45 kg
A white plastic housing weighing only 0.45 kg is the lightest figure among the Dahua recorders covered here. For a 4-channel system, which is often mounted in a small niche or on a compact bracket, that's not a minor detail: a lighter housing is easier to secure with no need for extra structural reinforcement.
MJPEG format alongside Smart H.265+
Besides Smart H.265+/Smart H.264+/H.265/H.264, the recorder also supports MJPEG — a rarity in modern models, but a useful detail for compatibility with older video-analytics software or specialized systems that still expect that specific frame format.
A -10°C to +55°C operating range — wider than the budget series
This model's operating temperature range reaches +55°C, while the base S3/H series is capped at +45°C. That 10-degree difference matters for rooms with no air conditioning during hot seasons — a utility room under a roof or an unheated warehouse can easily climb past +45°C in summer.
12 MP recording and an 80 MB/s input stream
Support for recording up to 12 MP per channel exceeds the budget series' 8 MP — detail that matters specifically for face recognition — and an 80 MB/s input stream ensures steady reception of video from all 4 channels with no frame-rate drop.
A 205×207×48 mm housing — compact even with full analytics
Housing dimensions of 205×207×48 mm are comparable to the base budget model with no analytics at all — face recognition and perimeter protection required no extra bulk or additional module that would have grown the device's footprint.
IP20 protection class and a 12-month warranty
An IP20 housing protection class tells the installer the recorder is meant for indoors, not outdoors, and the manufacturer's 12-month warranty covers factory defects and early component failures during the first year of operation.
Mouse control both locally and over the network
The recorder supports control both directly via mouse on site and remotely through a network client — the owner checks footage from home while a guard at the site simultaneously works with the same recorder locally, with neither access blocking the other.
Who this model is for
DHI-NVR21xx-I2 is the pick for an owner of a small site (a store, an entrance area, a small office) who needs visitor face identification but sees no point overpaying for 8 or 16 channels when there are only 4 cameras. Tell us your camera count and whether face identification specifically matters to you, and we can advise whether this model is enough.
