System Overview
Featuring powerful optical zoom and accurate pan/tilt/zoom
performance, this camera provides an all-in-one solution for capturing
long distance video surveillance for outdoor applications. Together with
infrared illumination and Starlight Technology, the camera is the perfect
solution for dark, lowlight applications. The series combines a day/night
mechanical IR cut filter for the highest image quality in variable lighting
conditions during the day.

Functions

Starlight Technology
With advanced image processing technology and optical technology,
Dahua Starlight technology can provide clear colorful video in the
environment of low illuminance. It widely applies to various
environments of low illuminance.

Protection (IP66, TVS 6000 V)
IP66, TVS 6000 V lightning proof, surge protection, and voltage transient
protection.

Perimeter Protection
Automatically filters out false alarms caused by animals, rustling
leaves,bright lights, etc. Enables system to act secondary recognition for
thetargets. Improves alarm accuracy.

Face Detection
Dahua Face Detection technology can detect the face in the image. With
deep learning algorithm, the technology supports detecting, tracking,
capturing and selecting the best face image, and then outputs face
snapshot.

SMD 4.0
Dahua Smart Motion Detection technology works with intelligent
algorithms to classify targets that trigger motion detection alarms. It
filters out objects that are not targets, such as small and large animals,
to avoid triggering false alarms. With an AI NVR, Quick Pick technology
becomes available, allowing you to easily search for and pick out human
and vehicle targets from SMD event videos, prioritizing the highest
matches.
