IPC-HDBW8841H-Z-LB
8MP WizMind Classroom Network Camera
> 8-MP 1/1.8" CMOS image sensor, low luminance, and high definition image.
> Outputs max. 8 MP (3840 × 2160)@25/30 fps.
> Supports Classroom Behavior Analysis, including detection of abnormal number of people (for tracking teachers), standing, writing on the blackboard, back turned to students, head up, and walking.
> Supports Exam Behavior Analysis, including detection of students looking around and passing objects between each other.
> Sound Management: With its built-in dual MICs and Dahua noise reduction algorithms, the camera supports the sound management function, using it to collect vocals in the classroom, adaptively reduce noise, and filter non-human voices.
> Built-in Hi-Fi large-diameter speaker covers an auditory range of 30 meters when used indoors.
> Supports two-way talk.
> Alarm: 3 in, 2 out; audio: 1 in, 1 out; built-in dual MICs, RS-485, BNC; supports max. 256 G Micro SD card.
> 24 VAC/12 VDC/PoE power supply, 12 VDC power output, and max. current 165 mA, easy for installation.
> 5 streams for 3-channel HD video display.
> IP67 and IK10 protection.

DORI (Detect, Observe, Recognize, Identify) is a standard system (EN-62676-4) for defining the ability of a person viewing the video to distinguish persons or objects within a covered area. The numbers in this table do not reflect intelligent function distances. For intelligent function distances, refer to installation and commissioning manual/project design tool. Intelligence
Classroom Behavior Analysis
Supports student mode and teacher mode.
Student mode:
Head up detection, standing detection, heads up people counting, and close-up of standing students.
Teacher mode:
Supports up to 5 face databases and 10,000 face images. It offers abnormal number of people detection (for tracking teachers), back turned to students detection, walking detection, writing on blackboard detection, and performs face comparison of teachers.Exam Behavior Analysis
Suport looking around and passing object detection
Face Recognition
Face recognition, track, priority, snapshot, face enhancement, face exposure
Face attribute extract, 6 attributes and 8 expressions: Gender, age, glasses, expressions (anger, sadness, disgust, fear, surprise, calm, happiness and confusion), mask, beard
Face matting setting: face, single inch photo
Two snapshot strategies: priority snapshot, recognition
Face angle filter
Priority time setting
Management of 5 group face libraries
Single person register and person register in batch
Face recognition and similarity setting
Max supports face contrast in face library with 100,000 faces
Support Duration OptimalSmart Search
Work together with Smart NVR to perform refine intelligent search, event extraction and merging to event videos
