DH-PTZ85848-HNF-PA
Perimeter Protection
Automatically filters out false alarms caused by animals, rustling leaves,
bright lights, and more, and uses secondary recognition during target
detection to improve alarm accuracy.
Starlight Technology
For challenging low-light conditions, Dahua's Starlight Ultra-low Light
Technology offers the best in light sensitivity, capturing color in vivid
detail, even in lighting as low as 0.005 lux. The camera uses a set of
optical features to balance light throughout the scene, producing clear
images in dark environments.
PFA Technology
PFA technology has introduced new methods of judgment that ensure
the accuracy and predictability of the direction of subject distance
adjustment. The result is a set of advanced focusing algorithms that
ensure image clarity when zooming and that shorten focus time.
This makes the camera highly advanced in its functions, substantially
improving the quality of your experience - Environment (–40 °C to +70 °C, IP67)
Developed to operate in extreme conditions, Dahua camera can function
in temperatures ranging from –40 °C to +70 °C (–40 °F to +158 °F) at
95% humidity. It was subjected to rigorous dust and water immersion
tests, gaining its IP67 Ingress Protection certification, making it suitable
for demanding outdoor applications.
Auto-tracking
This feature controls the pan, tilt and zoom actions of the camera to
automatically track an object in motion, to keep it in view of the camera.
Tracking can be triggered manually or automatically by defined rules.
Once a rule is triggered, the camera can zoom in and track the defined
target automatically.
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, a flexible multi-frame reference structure and intelligent noise
reduction to deliver high-quality videos without straining the network.
Smart H.265+ technology outranks standard H.265 video compression,
reducing bit rate and storage requirements by up to 70%.
Connectivity and Storage
-
H.265 Encoding: Supports efficient video compression for reduced bandwidth and storage requirements.
-
PoE Support: Simplifies installation with Power over Ethernet capability.
-
Micro SD Card Slot: Allows local storage of up to 512 GB.
Applications
Forest Fire Prevention
The PTZ85848-HNF-PA camera serves as a crucial tool for early detection of forest fires. Its 48× optical zoom and Starlight technology enable it to identify smoke or early signs of fire at great distances. The perimeter protection feature minimizes false alarms by filtering out movements caused by animals or natural elements. The camera's ability to function in extreme temperatures and its IP67 rating make it suitable for deployment in forest environments where weather conditions can be severe.
Weather Monitoring
The camera provides reliable performance in various weather conditions. Its advanced optical system and Starlight technology ensure clear imaging even in challenging lighting conditions. The robust construction allows it to operate continuously through extreme weather events, offering valuable observational data for weather forecasting and climate studies. The H.265 encoding ensures efficient storage of continuous monitoring footage.
Wildlife Management
The camera offers non-invasive monitoring capabilities that minimize human disturbance to natural habitats. The 48× optical zoom allows researchers to observe wildlife from a distance without approaching too closely. The auto-tracking feature helps monitor animal movements, while the perimeter protection detects potential incursions into protected areas. The Starlight technology ensures that wildlife activity can be observed during nocturnal hours, providing comprehensive data for behavioral studies.
The Dahua DH-PTZ85848-HNF-PA camera demonstrates versatility and reliability across multiple environmental applications. Its advanced features and robust design make it an invaluable tool for enhancing safety, environmental awareness, and conservation efforts in natural settings. The combination of high-resolution imaging, intelligent analytics, and environmental resilience positions this camera as a leading solution for modern surveillance needs in challenging outdoor environments.
