Dahua IP PTZ 2MP StarLight 45X Zoom 300M IR

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, low light applications. The series combines a day/night
mechanical IR cut filter for the highest image quality in variable lighting
conditions during the day, and True WDR for applications with direct
sunlight or glare.
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
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.
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.
PFA Technology
PFA technology has innovatively introduced new methods of judgment
to ensure the accuracy and predictability of the direction of subject
distance adjustment. The result is a set of advanced focusing algorithms.
PFA ensures clarity of the image throughout the process of zooming
and shortens focus time. The realization of PFA technology substantially
improves user experience and increases product value.
Dahua cameras operate in extreme temperature environments, rated
for use in temperatures from -40 °C to +60 °C (-40 °F to +140 °F) with
95% humidity. Subjected to rigorous dust and water immersion tests
and certified to the IP67 Ingress Protection rating makes it suitable for
demanding outdoor applications.
The camera allows for ±25% input voltage tolerance, suitable for the
most unstable conditions for outdoor applications. Its 8KV lightning
rating provides effective protection for both the camera and its structure
against lightning.
The camera conforms to the ONVIF (Open Network Video Interface
Forum) specifications, ensuring interoperability between network video
products regardless of manufacturer.
