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.
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.
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.
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.
