Dahua Technology N42AH3Z Overview

The Lite Series 4MP Outdoor Network Eyeball Camera from Dahua Technology features a 1/3″ progressive scan CMOS sensor and a 2.7-12mm varifocal lens for capturing videos at a maximum resolution of 2688 x 1520. 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 a usable video.

Enclosed in an IP67-rated housing, the camera can be used for both indoor and outdoor applications. This day/night camera provides 24-hour surveillance thanks to the removable IR cut filter and two built-in IR LEDs with a range of up to 197’. The Regions of Interest (ROI) is a user-defined feature that allows the operator to monitor specific areas of a scene while still maintaining overall situational awareness of less important areas.

With IR illumination, detailed images can be captured in low light or total darkness. The camera’s Smart IR technology adjusts the intensity of camera’s infrared LEDs to compensate the distance of an object. The Smart IR technology prevents IR LEDs from whiting out images as they come closer to the camera.

Capturing unnecessary data, such as video of surrounding hallway walls, can increase storage requirements without any added value. The image flip feature allows the camera’s image to be rotated in 90° increments for improved video optimization. The camera conforms to ONVIF (Open Network Video Interface Forum) specifications, ensuring interoperability between network video products regardless of the manufacturer.

The Smart H.264+ is the optimized implementation of the H.264 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 Smart H.264+ technology reduces bit rate and storage requirements by up to 70% when compared to standard H.264 video compression.

With support for ±10% input voltage tolerance, the camera can be used for outdoor applications with voltage fluctuations. The 6KV lightning rating protects the camera and its structure from the effects of lightning.1/3″ 4MP progressive scan CMOS sensorSmart H.264+ and H.264 dual-stream encoding4MP at 20 fps and 3MP at 30 fpsWDR (120 dB), Day/Night (ICR), 3D-DNR, AWB (Auto White Balance), AGC (Automatic Gain Control), and BLC (Backlight Compensation)Multiple Network Monitoring: Web Viewer, CMS (DSS/PSS), and DMSSmicroSD card slot (accepts cards up to 128GB)2.7-12 mm varifocal LensIR range of up to 197’IP67-rated housingSupports PoE
