DH-SD42212T-HN
2MP 12x Starlight PTZ Network Camera
System Overview
Featuring powerful opcal zoom and accurate pan/lt/zoom
performance, the camera provides a wide monitoring range and great
detail. The camera delivers 1080P resoluon at 25/30fps. The camera is
equipped with smooth control, high quality image, and good protecon,
meeng compact size demands of video surveillance applicaons.
Funcons
Starlight Technology
For challenging low-light applicaons, Dahua’s Starlight Ultra-low Light
Technology oers best-in-class light sensivity, capturing color details
in low light down to 0.005 lux. The camera uses a set of opcal features
to balance light throughout the scene, resulng in clear images in dark
environments.
Wide Dynamic Range
The camera achieves vivid images, even in the most intense contrast
lighng condions, using industry-leading wide dynamic range (WDR)
technology. For applicaons with both bright and low lighng condions
that change quickly, True WDR (120 dB) opmizes both the bright and
dark areas of a scene at the same me to provide usable video.
Smart H.265+
Smart H.265+ is the opmized implementaon of the H.265 codec that
uses a scene-adapve encoding strategy, dynamic GOP, dynamic ROI,
exible mul-frame reference structure and intelligent noise reducon
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 innovavely introduced new methods of judgment
to ensure the accuracy and predictability of the direcon 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 me. The realizaon of PFA technology substanally
improves user experience and increases product value.
Environmental
Dahua cameras operate in extreme temperature environments, rated
for use in temperatures from -30 °C to +60 °C (-22 °F to +140°F) with
95% humidity. The camera complies with the IK10 Vandal Resistance
impact rang. Subjected and cered to rigorous dust and water
immersion tests, the IP66 rang makes it suitable for demanding outdoor
applicaons.
Protecon
The camera allows for ±10% input voltage tolerance, suitable for the
unstable condions for outdoor applicaons. Its 2KV lightning rang
provides eecve protecon for both the camera and its structure
against lightning.
Interoperability
The camera conforms to the ONVIF (Open Network Video Interface
Forum) specicaons, ensuring interoperability between network video
products regardless of manufacturer.
