DORI (Detect, Observe, Recognize, Identify) is a standard system (EN-62676-4) for defining the ability of observers to distinguish people or objects in the covered area. The numbers in this table do not reflect distances for intelligent functions. For intelligent function distances, refer to the installation and commissioning guide/project design tools.

Intelligence

IVS (Perimeter Protection)
Intrusion, tripwire (both functions support precise classification and detection of vehicles and people)

Smart Search
Working with Smart NVR to perform intelligent search, event retrieval, and event video merging

Video

Video Compression
H.265; H.264; H.264H; H.264B; MJPEG (Supported only for sub-stream)

Smart Encoding
Smart H.265+; Smart H.264+

Frame Rate
Main stream: 2960 × 1668@(1–20 fps) / 2688 × 1520@(1–25/30 fps)
Sub-stream: 704 × 576@(1–25 fps) / 704 × 480@(1–30 fps)
The above values are the maximum frame rate of each stream; for multiple streams, the values depend on the overall encoding power.
