Dahua PTZ Security Camera: 2MP, Starlight 40X Zoom, IR 300m
DAHUA 2MP PTZ Camera, 40X Zoom, IR300m - DH-PTZ19240V-IRB-N(-B)
For challenging low-light applications, Dahua’s Starlight Ultra-low Light Technology offers best-in-class light sensitivity, capturing colour 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.
Ultra-Wide Dynamic Range
For applications with both bright and low lighting conditions that change quickly, Ultra WDR (140 dB) optimises both the bright and dark areas of a scene at the same time to provide usable video.
This feature controls the pan/tilt/zoom actions of the camera to automatically track an object in motion and to keep it in the scene. The tracking action 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+ is the optimised 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.
With Dahua smart wiper technology, the wiper can start/stop automatically when the built-in rain sensor detects rain. This technology offers better surveillance performance against wet weather and reduce dependence on manual operation.
Innovative PFA technology introduces 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 realisation of PFA technology substantially improves user experience and increases product value.
Dahua cameras operate in extreme temperature environments, rated for use in temperatures from -50 °C to +70 °C (-58 °F to +158 °F) with 95% humidity. Subjected to rigorous dust and water immersion tests and certified to the IP68 Ingress Protection rating makes it suitable for demanding outdoor applications.
The camera allows for ±25% input voltage tolerance, suitable for the most unstable conditions for outdoor applications. Its 8KV lightning rating 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.
