Starlight Technology.

Featuring Dahua’s Starlight Technology, this camera is ideal for
applications with challenging lighting conditions. Its low-light
performance delivers usable video with minimal ambient light. Even
in extreme low-light conditions, Starlight Technology is capable of
delivering colour images in near complete darkness (0.005 lux).

Wide Dynamic Range

Embeded with industry leading wide dynamic range (WDR) technology,
vivid pictures 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

With a temperature range of -40 °C to +60 °C (-40 °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 enviroments
with rain, sleet, snow and fog, an integrated wiper provides users with
clear visibility at all times.

Supporting ±30% input voltage tolerance, this camera suits even the
most unstable conditions for outdoor applications. Its 2KV lightning
rating provides protection 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.
