dahua IPC-D1B40 4MP IR Indoor Mini-Dome Network Camera


System Overview

  • EZ-IP is perfect for small to medium size applications like home/residential security, small retail shops, and other typical SMB applications. It offers a perfect alternative to migrate from analog to an IP system with its easy to use nature and cost effectiveness.
  • EZ-IP is fully in line with Dahua’s quality. Stable and reliable components are utilized and Various tests such as anti-vibration, water resistance, and aging tests are performed to ensure Dahua quality standards.

  • 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.
  • 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
    With IR illumination, detailed images can be captured in low light or total darkness. 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 technology prevents IR LEDS from whiting 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 20m (65ft).
  • 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.
  • Environmental
    Dahua cameras operate in extreme temperature environments, rated for use in temperatures from -20° C to +50° C (-4° F to +122° F) with 95% humidity.
  • Protection (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.
  • Interoperability
    The camera conforms to the ONVIF (Open Network Video Interface Forum) specifications, ensuring interoperability between network video products regardless of manufacturer.
