AI series products adopt the most advanced AI technologies, including deep learning algorithms that primarily target people and vehicles,
which provides higher flexibility and accuracy for end-users. This enables
the Dahua AI series to offer various advanced applications such as Face
Recognition, ANPR, Metadata, People Counting, traffic data statistics,
etc. The complete lineup of Dahua AI includes network (PTZ) cameras,
network video recorders, servers, and more devices. Beyond seeing the
world, the power of AI allows devices to perceive the environment and
understand the world in a better way.
System Overview
Dahua PTZ AI 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.
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 filters the motion detection alarm triggered by non-concerned target and recognize human and
vehicle effectively, sending alarms when human and vehicle intrudes.
