Dahua PTZ-HD-SD49425XB-HNR 4MP 25x Starlight

System Overview
Dahua PTZ WizSense network camera adopts advanced CNN deep
learning algorithms to support Perimeter Protection with high accuracy.
This camera possess wide monitor range, PFA algorithm that can always
present a clear, focused image while zooming. 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.
Perimeter Protection
Automatically filtering out false alarms caused by animals, rustling
leaves, bright lights, etc. Enables system to act secondary recognition
for the targets. Improving alarm accuracy.
Environmental
Dahua cameras operate in extreme temperature environments, rated
for use in temperatures from -40 °C to +70 °C (-40 °F to +158 °F) with
95% humidity. Subjected to rigorous dust and water immersion tests
and certified to the IP66 Ingress Protection rating makes it suitable for
demanding outdoor applications.
Protection
The camera allows for 6KV lightning rating,which provides effective
protection for both the camera and its structure against lightning.
Interoperability
The camera conforms to the ONVIF (Open Network Video Interface
Forum) specifications, ensuring interoperability between network video
products regardless of manufacturer.
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.
SMD PLUS
With Deep-Learning Algorithm, Dahua SMD PLUS Pfilters the motion
detection alarm triggered by non-concerned target and recognizes human and vehicle effectively , sending alarms when human and vehicle
intrude.
