If you’ve landed here, you’re looking for a recorder that:

✅ records in resolution up to 12 Mpx – this is high quality guaranteeing a wide frame and high pixel density

✅ built-in 8-port PoE switch , 25.5 W / Channel – PoE (802.3af / at)

✅ built-in AI functions : object classification – human/vehicle (4 channels)

✅ SMD+ – object classification with false alarm filtering

✅ allows recording from 8 IP cameras simultaneously

✅ has remote live viewing in the manufacturer’s application

✅ has a HDD space up to 1×20 TB

✅ archives on external USB drives

✅ enables control of PTZ rotating heads

✅ access from mobile phone (Android, iOS)

Face Detection

Face detection is to detect if there is any human face appearing in the video. This technology adopts a deep learning algorithm to support face detection, tracking, optimization and capturing, and then output the best face snapshot.

Face Recognition

Dahua Face Recognition technology extracts the features of captured faces and compares them with those in face database to recognize the person identity.

Perimeter Protection

Automatically filtering out false alarms caused by animals, rustling leaves, bright lights, etc. Enables system to perform secondary recognition for the targets. Improving alarm accuracy.

AI Search

Support AI seach by metadata of different targets or uploading face pictures to device and comparing them with recorded faces by similarity. Enable operators to quickly and easily search through multi channels and long duration, efficiently find out when and where a person of interest appeard.

Heat Map by Camera

Dahua heat map technology is used to display the crowd density and people appearance probability. Export and display the crowd status by different colors. Generally, the crowd status is the statistics of people quantity in space and time dimensions.

Quick Pick

Dahua Quick Pick technology can enable users to quickly pick up the human/vehicle targets that they are interested in, which facilitates retrieval from SMD events.

Support for cameras with AI functions (Motion Detection + Intelligent Image Analysis)

The recorder supports Intelligent Image Analysis and motion detection , making it perfect for use with modern IP cameras.

Additionally, the ability to view live images from cameras on a smartphone allows you to assess the situation on an ongoing basis, as you receive an appropriate notification on your phone when an alarm is triggered/an event is detected.

The functions are implemented in cooperation with the recorder and cameras that support these functions:

✅ Advanced perimeter protection features: intrusion, line crossing with separate rules for vehicles and pedestrians,

✅ Classification of people and vehicles ,

✅ SMD PLUS – search for an object classified as: human, motor vehicle

✅ Motion detection

✅ Privacy zones

SMD+ false alarm filtering

The camera uses artificial intelligence (AI) self-learning technology to distinguish objects appearing in the frame and filter out alarms.

This technology can distinguish between a person, a car or a small animal. Small animals, moving leaves, rain or falling shadows do not trigger an alarm.

Cooperation with cameras with the function of counting people

The camera can track and process moving people who enter, exit and pass designated areas during specific time periods. Data is counted after discarding irrelevant, unwanted measurements (shopping carts, loiterers, staff, etc.)

Cooperation with cameras with “Heat Map”

The heat map is the best feature for defining which areas of the room are of interest to visitors . Red shows the highest density, while blue shows the lowest. What’s more, the heat map also recreates how customers move around the store and how much time they spent at each stand/shelf.

Motion detection + Intelligent image analysis

The recorder has support for Intelligent Image Analysis and motion detection , making it perfect for use with modern IP cameras.

Additionally, the ability to view live images from cameras on a smartphone allows you to assess the situation on an ongoing basis, as we receive an appropriate notification on our phone when an alarm is triggered/an event is detected.

The functions are implemented in cooperation with the recorder and cameras supporting these functions:

✅ Advanced perimeter protection functions: intrusion, crossing the line with separate rules for vehicles and pedestrians,

✅ classification of people and vehicles ,

✅ face detection ,

✅ counting people ,

✅ SMD PLUS – searching for an object classified as: human, motor vehicle, non-engine vehicle

PTZ camera control function

Dahua NVRs allow you to manage the basic parameters of PTZ (rotary) network cameras. Controlling various camera functions such as zoom and focus, rotation speed, manual definition of the field of view.

It guarantees control of the monitoring system to the maximum extent possible, tailored to the user’s needs.

Connecting cameras

In the NVR4104HS-P-EI Dahua recorder, cameras are connected via an external PoE switch. This recorder model can support up to 4 IP cameras . Below is a diagram of connecting IP cameras via a switch to the recorder (using a 4-channel PoE switch as an example).
