The Lite Series is a great choice for consumers looking for high quality
monitoring products at a reasonable price. Its low cost and high
performance make it ideal for residential areas and SMB solutions. This
series is equipped with a wide range of technologies, such as full-color
and starlight, providing various solutions for different scenarios.
System Overview
Full-color
With its advanced image processing algorithm and capability to absorb
large quantities of light, the camera provides colorful monitoring that
collects clear and highly detailed information, significantly increasing
the reliability of the human and vehicle images that are collected as
evidence for intelligent analysis.
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.
Wide Dynamic Range
With its advanced Wide Dynamic Range technology (WDR), the camera
captures highly detailed images and produces high-definition recordings
in high-contrast lighting conditions, and in scenes with backlighting or
shadows.
Super Adapt
With its intelligent algorithm, the camera automatically adjusts its
parameters to provide optimal performance and vivid images.
Advanced 3DNR
Dahua’s advanced 3DNR technology reduces image noise with little to
no impact on image sharpness, especially in poor lighting conditions.
It detects the noise, and compares the sequential frames to effectively
reduce the noise. It also makes efficient use of bandwidth, saving on
storage space.
Functions

Smart Dual Light
With its smart dual light mechanism, the camera automatically turns on
the white light when Perimeter Protection/SMD Plus function of AI XVR
detects a target in the rule area to capture clear, vivid images. When the
target leaves the rule area, the camera automatically switches over from
the white light to the IR light to significantly reduce light pollution.
Protection
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.
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.
