Functions
Smart Codec (H.265+ & H.264+)
Smart Codec is the optimized implementation of standard video
compression (H.265 & H.264) 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 Codec technology reduces bit rate
and storage requirements by up to 70% when compared to the standard
video compression.
Starlight Technology
For challenging low-light applications, Dahua’s Starlight Ultra-low Light
Technology offers best-in-class light sensitivity, capturing color details
in low light down to 0.006lux. The camera uses a set of optical features
to balance light throughout the scene, resulting in clear images in dark
environments.
Wide Dynamic Range(WDR)
The camera achieves vivid images, even in the most intense contrast
lighting conditions, using industry-leading wide dynamic range (WDR)
technology. For applications with both bright and low lighting conditions
that change quickly, true WDR (120 dB) optimizes both the bright and
dark areas of a scene at the same time to provide usable video.
Intelligent Video System (IVS)
IVS is a built-in video analytic algorithm that delivers intelligent functions
to monitor a scene for Tripwire violations, intrusion detection, and
abandoned or missing objects. A camera with IVS quickly and accurately
responds to monitoring events in a specific area. In addition to scene
analytics, the camera supports face detection to quickly capture a
face and upload the image to a server. The camera also offers tamper
detection by recognizing a dramatic scene change and generating a
warning message to inspect the camera.
