Three Signals over One Coaxial Cable

HDCVI technology simultaneously transmits video, audio and data over
a single coaxial cable. Dual-way data transmission allows the HDCVI
camera to communicate with an HCVR to send control signals or to
trigger alarms.

Long Distance Transmission

HDCVI technology guarantees real-time transmission over long distances
without loss of video quality. HDCVI cameras provide the same resolution
as most IP network camera systems using existing RG-59, RG-6, or CAT 6
UTP cabling.

Simplicity

HDCVI technology seamlessly integrates traditional analog surveillance
systems with upgraded, high-quality HD video, making it the best choice
to protect security investments. The plug and play approach enables full
HD video surveillance without the hassles of configuring a network.

Smart IR

The camera is designed with microcrystalline LED IR illumination for
low-light performance. Smart IR is a technology to ensure brightness
uniformity in black and white images under low illumination. Dahua’s
unique Smart IR adjusts to the intensity of the camera’s infrared LEDs
to compensate for the distance of an object, and prevents IR LEDs from
overexposing images as the object come closer to the camera.

Multiple-format Support

The camera supports multiple video formats including, HDCVI, CVBS,
AHD, and TVI. The camera can switch between these four formats via the
OSD menu or the switch located on the video output cable, making the
camera compatible with not only HDCVI DVRs but also most existing HD/
SD DVRs.

Environmental

With a built-in heater and a temperature range of —40° C to +60° C
(—40° F to +140° F), the cameras are designed for extreme temperature
environments. The cameras, subjected to rigorous dust and water
immersion tests, are certified to the IP67 rating making them suitable for
demanding outdoor applications.
