2MP IR HDCVI Fixed-focal Bullet Camera DH-HAC-B5E20P

Series Overview

Cost-effective and easy to use, ECO series cameras perform
outstandingly, meeting the quality standards of Dahua. It offers the
full-color model and IR model, making them ideal for a variety of
scenarios.

Functions

Smart IR Illumination

With its IR illumination, the camera provides optimal performance
in low light conditions, ensuring uniformity in the brightness of B/W
images. Through its smart IR technology, the camera also compensates
for the distance of targets by adjusting the intensity of its IR LEDs,
preventing overexposure of images as targets move closer to the
camera.

Broadcast-quality Audio

Audio signal transmission over coaxial cables is supported by the
HDCVI camera. It adopts a unique audio processing and transmission
technology that restores source audio and eliminates noise, ensuring
the quality and reliability of the audio information that is collected. This
becomes important for video surveillance applications that use audio
information as a type of supplementary evidence.

4 Signals over 1 Coaxial Cable

HDCVI technology supports 4 signals (video, audio*, data and power)
which are simultaneously transmitted over a coaxial cable. Dual-way
data transmission allows the HDCVI camera to interact with the XVR to
perform various actions such as sending control signals and triggering
alarms. HDCVI technology also supports PoC, which makes the camera
easy and quick to install.
* Audio input is available for select HDCVI camera models.
Long Distance Transmission
HDCVI technology provides long distance transmission in real time
without transmission loss. It supports transmission distances up to 700
m for 2-MP/5-MP/8-MP HD videos through coaxial cables, and up to 300
m through UTP cables. The results were obtained and verified through
rigorous testing in Dahua’s test laboratory.
Simplicity
HDCVI technology inherits the simplicity of traditional analog
surveillance systems, making it a great mechanism for protecting your
valuables. HDCVI can be upgraded from the traditional analog system
without replacing the existing coaxial cabling. Its plug and play design
enables it to produce high-definition videos during surveillance without
the hassle of configuring a network.
Protection (IP67, Wide Voltage)
IP67: The camera passed a series of rigorous dust and immersion tests.
Its enclosure is both dust-proof and waterproof, and can function
normally while being immersed in 1 m deep water for up to 30 minutes.
Wide voltage: The camera has ±30% input voltage tolerance (for some
power supplies) and a wide voltage range, making it suitable for a
variety of outdoor scenarios.
