Dahua WizSense 2MP 25x Starlight IR PTZ AI Network Camera DH-SD49225XA-HNR

Dahua PTZ WizSence 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 ex
cellent low light performance due to adopting the latest starlight tech
nology. 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.


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.
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.


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.

The camera allows for 6KV lightning rating,which 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.

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.


With Deep-Learning Algorithm, Dahua SMD PLUS filters the motion de

tection alarm triggered by non-concerned target and recognizes human 
and vehicle effectively, sending alarms when human and vehicle intrude.
