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.
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.
