Dahua Technology Pro Series 4MP Outdoor Network Wedge Dome Camera with Night Vision and 2.8mm Lens


Dahua Technology N44BN52 Overview

The Pro Series 4MP Outdoor Network Wedge Dome Camera from Dahua Technology features a 1/3″ progressive scan CMOS sensor and 2.8mm fixed lens for capturing videos at a maximum resolution of 2688 x 1520. Enclosed in an IP67- and IK10-rated housing, the camera can be used for both indoor and outdoor applications in areas at risk of vandalism. For applications with both bright and low light 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.

The IVS (Intelligent Video System) is a built-in video analytics algorithm that delivers intelligent functions to monitor a scene for tripwire violations, intrusion, and abandoned or missing objects. A camera with IVS responds 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 to generate a warning message that prompts you to inspect the camera.

The H.265 video compression standard offers improved compression by expanding pattern comparison and difference-coding, improving motion vector prediction and motion region merging, and incorporating an additional filtering step called sample-adaptive offset filtering.

Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction to deliver video without straining the network.

The camera comes with Smart IR technology that adjusts the intensity of the camera’s infrared LEDs to compensate for the distance of an object. Smart IR technology prevents IR LEDs from whiting out images as they come closer to the camera.

With a temperature range of -22 to +140°F, the camera is designed for use in harsh temperature environments. With support for ±30% input voltage tolerance, the camera can be used for outdoor applications with voltage fluctuations. The 6kV lightning rating indicates the camera and its structure are protected from the effects of lightning.
