Super Adapt
With its intelligent algorithm, the camera automatically adjusts its
parameters to provide optimal performance and vivid images.
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.
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.
