Environmental
Dahua cameras operate in extreme temperature environments, rated for
use in temperatures from -30° C to +60° C (-22° F to +140° F) with 95%
humidity, allowing the camera to operate in the harshest environments.
Protection(IP67, wide voltage)
The camera allows for ±30% input voltage tolerance, suitable for the
most unstable conditions for outdoor applications. Its 4KV lightning
rating provides effective protection for both the camera and its structure
against lightning. Subjected and certified to rigorous dust and immersion
tests (IP67), the camera is the choice for installation in even the most
unforgiving environments.
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.
