8MP IR Vari-focal Bullet WizSense Network Camera

Launched by Dahua Technology, WizSense is a series of AI products and
solutions that adopt independent AI chip and deep learning algorithm.
It focuses on human and vehicle with high accuracy, enabling users to
fast act on defined targets. Based on Dahua's advanced technologies,
WizSense provides intelligent, simple and inclusive products and
solutions.

Series Overview

With advanced deep learning algorithm, Dahua WizSense 3 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, by working with AI NVR.

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, fast
moving,parking detection, loitering detection and gathering detection)
are largely reduced, by working with AI NVR.

accurate detection of vehicle and human, by working with AI NVR)

· Abnormality detection: Motion detection, video tampering, scene

changing, audio detection (Only - ZAS support), no SD card, SD card

full, SD card error, network disconnection, IP conflict, illegal access, and

voltage detection

· SMD Plus

Starlight

Dahua Starlight technology mainly applies to the environment of
low illumination, and it can provide clear colorful video. Even in the
environment of min. illumination, the technology can guarantee the
good image effect.

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.

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 works normal after soaking
in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% input voltage tolerance (wide
voltage range), and it is widely applied to outdoor environment with
instable voltage.
