System Overview
Featuring powerful optical zoom and accurate pan/tilt/zoom
performance, this camera can provide large monitoring range and great
detail. The camera has very excellent low light performance due to
adopting the latest starlight technology. The camera is equipped with
smooth control, high quality image and good protection, which make it
can meet most of the requirements of video surveillance applications.

Functions
Starlight Technology
For challenging low-light applications, Dahua’s Starlight Ultra-low Light
Technology offers best-in-class light sensitivity, capturing color details
in low light down to 0.005 lux. The camera uses a set of optical features
to balance light throughout the scene, resulting in clear images in dark
environments.

Wide Dynamic Range
The camera achieves vivid images, even in the most intense contrast
lighting conditions, using industry-leading wide dynamic range (WDR)
technology. For applications with both bright and low lighting conditions
that change quickly, True WDR (120 dB) optimizes both the bright and
dark areas of a scene at the same time to provide usable video.

Auto-tracking
This feature controls the pan/tilt/zoom actions of the camera to
automatically track an object in motion and to keep it in the scene. The
tracking action can be triggered manually or automatically by defined
rules. Once a rule is triggered, the camera can zoom in and track the
defined target automatically.

Smart H.265+
Smart H.265+ is the optimized implementation of the H.265 codec that
uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI,
flexible multi-frame reference structure and intelligent noise reduction
to deliver high-quality video without straining the network. Smart
H.265+ technology reduces bit rate and storage requirements by up to
70% when compared to standard H.265 video compression.
