Dahua PTZ WizSence network camera adopts advanced CNN deep learning algorithms to support Perimeter Protection with high accuracy.
This camera possesses 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 makes it meet most of the requirements of video surveillance applications.
Perimeter Protection
Automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc. Enables system to act secondary recognition for the
targets to improve 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.
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.
Environment
Dahua camera can operate in extreme temperature environments, rated for use in temperatures from —40 °C to +65 °C (—40 °F to +149 °F)
with 95% humidity. Subjected to rigorous dust and water immersion tests and certified to the IP66 Ingress Protection rating make it suitable
for demanding outdoor applications.
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.
Protection
The camera allows for 6 kV lightning rating, which provides effective protection for both the camera and its structure against lightning.
Smart H.265+
Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI,
flexible multi-frame reference structure and intelligent noise reduction 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.
