System Overview

The IR Megapixel Fixed camera delivers 4MP resolution with a

2.8mm/3.6mm fixed lens.The camera’s elegant blend of aesthetics

combined with a range of easy mounting solutions provides an excellent

choice for a variety of small to mid-size applications at an affordable

price.

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.

Intelligent Video Analysis (IVS)

Dahua camera is equipped with a built-in intelligent analytic algorithm

based on video, which can realize intelligent functions like Tripwire

and Intrusion, to quickly and accurately respond to monitoring events

in specific area, It can enhance monitoring efficiency. In addition, the

camera supports intelligent tamper detection, which is to generate

warning message via detecting dramatic scene change and to guarantee

effective video surveillance.

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

Smart IR Technology

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. Smart

IR technology prevents IR LEDs from whitening out images as they come

closer to the camera. The camera’s integrated infrared illumination

provides high performance in extreme low-light environments up to 30m

(98ft).

Protection (IP67, wide voltage)

The camera allows for ±25% input voltage tolerance, suitable for the

most unstable conditions for outdoor applications. Its 2KV lightning

rating provides effective protection for both the camera and its structure

against lightning. Subjected and certified to rigorous dust and immersion

tests (IP67) , the camera is the choice for installation in even the most

unforgiving environments.

Environmental

Dahua cameras operate in extreme temperature environments, rated for

use in temperatures from -30° C to +60° C (-22° F to +140° F) with 95%

humidity.

Image Flip

Capturing unnecessary data such as 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

better video optimization.

Interoperability

The camera conforms to the ONVIF (Open Network Video Interface

Forum) specifications, ensuring interoperability between network video

products regardless of manufacturer.
