If you haven’t heard of the Dahua WizSense series, well, too bad. The top feature of the series and all devices in it is the AI Artificial Intelligence Processor as a foundation, which enables the device to execute intelligent functionality like face recognition, advanced motion detection, and perimeter protection, and use deep learning algorithms. And there’s nothing so special about this guy, we've seen a lot similar, but what makes this one special is that it’s fresh and brand-new, it just launched, it’s smart, and it is priced below $100. A really odd fact.
Features Overview
Alright, what NVR2104-I is capable of: face detection and, more importantly, face recognition, meaning a full-featured search and comparison over the entire database. Also, the face tracking, optimization, and results output. But! We are limited by only a single channel for this function. But! What this single channel offers is 8 faces processing at once in 1s, strangers’ detection and filtering, searching and comparing due to the power of artificial intelligence over the entire database using 8 photos of the suspect’s face at once. Advanced lists and filtering, and we can upload 10 databases in here with as many as 5,000 faces in total.
SMD Plus
Next – the thing named “SMD Plus”. So, this is a Dahua-specific feature, where SMD stands for Smart Motion Detection, that can be activated on all 4 channels in the recorder. And what it is, it’s basically a more accurate motion detection. Accurate here means the advanced objects filtering – only people and vehicles are in focus, and you can search by these labels in the database. The technology cuts off the detection of animals, the detection of trees and leaves on them, and all other inanimate objects in sight. SMD plus can take no notice of lighting changes and weather conditions like rain, snow, and wind.
Perimeter Protection & Intrusion Detection
On Dahua NVR2104-I are made due to the artificial super-mind too, and what can I say – more accuracy and the ability to search the database by labels, whether it’s a car or a man.
Dahua’s H.265+
A few words about Dahua’s H.265+ video compression technology – Dahua promises a reduced up to 30% video file size and the bandwidth, accordingly, in comparison to the standard H.265 codec. And up to 80% in comparison to the older H.264. And these numbers are achieved by the advanced compression allocation. You see, the objects of our interest, the moving objects, people, and vehicles, are recorded in good quality, but fixed objects are compressed way more. But don’t worry, it won’t look like what you see now on the GIF below, this is a conscious exaggeration. The bottom line is that the required objects look good and are compressed just slightly, but the level of detail of unwanted things is what we have sacrificed to get a reduction.

Hardware & Common
Concerning the common characteristics, 1 channel for cameras under 8 MP resolution. 4K, but for a single camera only. The rest 3 are up to 2 MP FullHD, 30 FPS. The maximum hard drive capacity supported is 6 TB. We have here 3 ONVIF profiles supported for 3rd-party cameras. That is: live streaming, saving and recording of videos onto the hard driveand H.265 compression rate support for 3rd party cameras. The motion detection events and the tamper alarm, and even a PTZ camera over the network in live mode. Regarding the ports and interfaces: 2 USB 2.0, HDMI, VGA, RJ-45 for twisted pair, RCA in and out, and 12V power in.
Also, what’s awesome on the setup stage is the fresh web-interface version 4.0, which you can see on our YouTube channel with activation and setting up smart functions.
Awesome, device regarding intelligent functionality and feature set, regarding the price, and the comfort when using it, thanks to the new UI. I enjoyed working with this Dahua NVR2104-I network video recorder, based on the artificial intelligence processor, and I hope you like it too.
