Dahua PTZ-DH-SD49225XA-HNR 2MP 25X OPTICAL ZOOM WDR IP66 PTZ CAMERA 100METER

System Overview
Dahua AI PTZ network camera adopts advanced CNN deep learning
algorithms to support face recognition with high accuracy. This camera
possesses wide monitoring range and PFA algorithm that can always
present a clear, focused image while zooming, and adopts smart wiper
technology that supported by RainSensor.
Functions
Perimeter Protection
Automatically filters out false alarms caused by animals, rustling leaves,
bright lights, etc. Enables system to act secondary recognition for the
targets. Improves alarm accuracy.
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.
Environment
Dahua cameras can 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 6 kV lightning rating, which provides effective
protection for both the camera and its structure against lightning.
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.
