Functions
Wide Dynamic Range
Embeded with industry leading wide dynamic range (WDR) technology,
vivid picutures are achieved even in the most intense contrast lighting
conditions. For applications with both bright and low lighting conditions
that change quickly, True WDR (120dB) optimizes both the bright and
dark areas of a scene at the same time to provide usable video.
Intelligent Video System (IVS)
With built-in intelligent video analytics, the camera has the ability to
detect and analyze moving objects for improved video surveillance. The
camera provides optional standard intelliegence at the edge allowing
detection of multiple object behaviors such as abandoned or missing
objects. IVS also supports Tripwire analytics, allowing the camera to
detect when a pre-determined line has been crossed, ideal for business
intelligence, and Facial Detection, for searching or identification of
individuals.
Environmental
With a temperature range of -30 °C to +60 °C (-22 °F to +140 °F), the
camera is designed for extreme temperature environments. Subjected
and certified to rigorous dust and water immersion tests, the IP67 rating
makes it suitable for demanding outdoor applications. For enviorments
with rain, sleet, snow and fog, an integrated wiper provides users with
clear visibility at all times.
Protection
Supporting ±30% input voltage tolerance, this camera suits even the
most unstable conditions for outdoor applications. Its 4KV lightning
rating provides protectection against the camera and its structure from
the effects of lightning.
Smart H.265+
Deliver high quality video without straining the network, Smart H.265+
is the optimized implementation of H.265. The Smart H.265+ encoding
technology includes a scene adaptive encoding strategy, dynamic GOP,
dynamic ROI, flexible multi-frame reference structure and intelligent
noise reduction, providing saving of up to 70% of bandwidth and storage
when compared with standard H.265.
HEVC (H.265)
H.265 ITU-T VCEG is a new video coding standard. H.265 Following
standard developed around the existing video coding standard H.264
, some retain the original technology , while some of the relevant
technology to improve the new technology uses advanced technology
to improve the relationship between the code stream , encoding quality
, and the delay between algorithm complexity , optimize settings
specific contents include : Improve compression efficiency , improve the
robustness and error recovery capabilities, real-time to reduce the delay,
reduce channel acquisition time and a random access delay , reduce
complexity , etc
