  • 4Intelligent Business Analysis

The NK8BA4 Ultra Series 12MP DWDR Network Box Camera from Dahua Technology features a 1/1.7" progressive scan CMOS Sony STARVIS sensor. It uses the Smart H.265+ video compression standard to improve encoding efficiency while preserving video quality. The camera features built-in business intelligence algorithms, auto back focus, PoE, and a microSD card slot. It supports H.265 and H.264 dual codec compression formats with triple-stream encoding.

Electronic Pan/Tilt/Zoom (ePTZ)

It scans a portion of the scene and zooms in for a detailed view. Coupled with an ultra high resolution, ePTZ lets an operator monitor a large area from a single camera.

Intelligent Video System (IVS)

The camera uses an IVS analytic algorithm that delivers intelligent functions to monitor a scene for tripwire violations, intrusion detection, and abandoned or missing objects. This algorithm lets the camera respond to monitoring events in a specific area. In addition to scene analytics, the camera supports face detection to 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.

Intelligent Business Analysis

The built-in IVS features people counting and heat map functionality. Intelligent Analysis tracks and stores daily, weekly, monthly, and yearly people flow through a defined scene and produces a configurable report. The system uses this data to produce a heat map, a two-dimensional representation of data that provides an immediate visual summary of information. People counting and heat maps can identify the most active areas of a retail space, providing valuable data analysis for commercial applications.
