Security cameras Dahua Technology

1/3" CMOS, 2688 x 1520px, 256MB RAM, F2.0, 3.6mm, 3D DNR, RJ-45, IP67, 380 g, Intelligent Video System System Overview
The IR Megapixel Fixed MiniDome camera delivers 4MP resolution with a choice of 2.8mm, 3.6mm, or 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.

Functions
True Day/Night
A day/night mechanical IR cut filter makes this camera ideal for applications with fluctuating lighting conditions, delivering color images during the day and automatically switching to monochrome as the scene darkens.

Regions of Interest
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.

Smart IR
The camera's Smart IR technology adjusts to the intensity of camera's infrared LEDs to compensate for the distance of an object. Smart IR prevents IR LEDS from whiting out images as they come closer to the camera. The camera's integrated IR illumination provides high performance in extreme low-light environments up to 30m (98ft).

Image Flip
Capturing unnecessary data such as surrounding hallway walls can increase storagerequirements without any added value. The image flip feature allows the camera's image to be rotated in 90°increments for better video optimization.

Wide Dynamic Range
Embedded with industry leading wide dynamic range (WDR) technology,vivid pictures are achieved even in the most intense contrast lightingconditions. For applications with both bright and low lighting conditions that change quickly,True WDR (120dB) optimizes both the bright and dark areas of a scene at the same time toprovide usable video.

Intelligent Video System (IVS)
With built-in optional intelligent video analytics, the camera has the ability to detect and analyze moving objects for improved video surveillance. Thecamera provides optional standard intelligence at the edge allowing detection of multiple object behaviors such as IVS also supports Tripwire analytics, allowing the camera to detect when a pre-determined line has been crossed, and Facial Detection, for searching or identification of individuals.

Protection
The camera's outstanding reliability is unsurpassed due to its rugged design. The camera isprotected against water and dust to IP67 standards, making it suitable for indoor or outdoor environments. With its IK10 rated impact resistant design, the camera provides maximum durability against vandals making it capable of withstanding the equivalent of 55kg (120lbs) of force.
Supporting ±25% input voltage tolerance, this camera suits even the most unstable conditions for outdoor applications.
Its 8KV lightning rating provides protection against the camera and its structure from
the effects of lightning.

Streaming
With a choice of unicast or multicast streaming, bandwidth-efficient viewing, recording and third-party video management can easily be achieved. Multiple streaming enables bandwidth
-efficient viewing and recording. Depending on the resolution and frame rate selected on the first stream, the second and third stream provides a copy at a lower resolution.

Smart H.264+
Delivering high quality video without straining the network, Smart H.264+ is the optimized implementation of H.264. The Smart H.264+encoding platform includes
a scene adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structureand intelligent noise reduction,providing a savings of up to 70% of bandwidth and storage when compared with standard H.264.
