Product Usage Instructions

Intelligent Functions

The Dahua WizSense 2 Series network camera supports intelligent functions, such as perimeter protection and smart motion detection, through its advanced deep learning algorithm. These features allowyou to enhance security and quickly respond to defined targets.

Starlight Technology

This camera series incorporates starlight technology, which improves image quality in low-light conditions, ensuring better visibility even in challenging lighting environments.

SMD Plus

The Smart Motion Detection (SMD) Plus technology utilizes an intelligent algorithm to categorize motion detection triggers and filter out alarms caused by non-concerned targets. This ensures effective and accurate alarm notifications.

Smart Encoding

Dahua’s smart encoding technology, including Smart H.265+ and Smart H.264+, employs an advanced scene-adaptive rate control algorithm. This results in higher encoding efficiency compared to traditional H.265 and H.264 codecs, providing high-quality video while reducing storage and transmission costs.

Perimeter Protection

With its deep learning algorithm, the Dahua Perimeter Protection technology accurately recognizes humans and vehicles, reducing false alarms in restricted areas such as pedestrian zones and vehicle areas. Intelligent detection based on target type, such as tripwire and intrusion, is significantly improved.

WDR

The camera’s advanced Wide Dynamic Range (WDR) technology ensures clear details in environments with strong brightness contrast. It can capture clear video even in high-brightness or backlit conditions.

Cyber Security

Dahua network cameras prioritize cybersecurity with a range of security technologies. These include security authentication and authorization, access control protocols, trusted protection, encrypted transmission, and encrypted storage. These measures enhance the camera’s defense against external cyber threats and prevent unauthorized access or compromise.

System Overview

With advanced deep learning algorithm, Dahua WizSense 2 Series network camera supports intelligent functions, such as perimeter protection and smart motion detection. With starlight technology, this series camera provides a better image effect in the condition of low illuminance.

Functions

SMD Plus
With intelligent algorithm, Dahua Smart Motion Detection technology can categorize the targets that trigger motion detection and filter the motion detection alarm triggered by non-concerned targets to realize effective and accurate alarm.

Smart H.265+ & Smart H.264+
With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission.

Perimeter Protection
With deep learning algorithm, Dahua Perimeter Protection technology can recognize human and vehicle accurately. In restricted area (such as pedestrian area and vehicle area), the false alarms of intelligent detection based on target type (such as tripwire, intrusion) are largely reduced.

8-MP 1/2.7″ CMOS image sensor, low luminance, and high definition image.
Outputs max. 8 MP (3840 × 2160)@20 fps and supports 2688 × 1520 (2688 × 1520)@25/30 fps.
H.265 codec, high compression rate, ultra-low bit rate.
Built-in IR LED, and the max. illumination distance is 40 m.
ROI, SMART H.264+/H.265+, flexible coding, applicable to various bandwidth and storage environments.
Rotation mode, WDR, 3D NR, HLC, BLC, digital watermarking, applicable to various monitoring scenes.
Intelligent monitoring: Intrusion, tripwire (the two functions support the classification and accurate detection of vehicle and human).
Abnormality detection: Motion detection, video tampering, audio detection, no SD card, SD card full, SD card error, network disconnection, IP conflict, illegal access, and voltage detection.
Supports max. 256 G Micro SD card; built in MIC.
12 VDC/PoE power supply, easy for installation.
IP67 protection.
SMD Plus.

WDR
With advanced Wide Dynamic Range (WDR) technology, Dahua network camera provides clear details in the environment of strong brightness contrast. The bright and dark area can get clear video even in high brightness environment or with backlight shadow.

Cyber Security
Dahua network cameras employ a series of security technologies, including security authentication and authorization, access control protocols, trusted protection, encrypted transmission and encrypted storage. These technologies improve the camera’s defense against external cyber threats and prevent malicious programs from compromising the device.

Protection (IP67, Wide Voltage)
IP67: The camera passes a series of strict test on dust and soak. It has dust- proof function, and the enclosure can work normally after soaking in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.
