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.
