Advanced 3DNR
3DNR is noise reduction technology that detects and eliminates random
noises by comparing two sequential frames. Dahua’s advanced 3DNR
technology allows remarkable noise reduction with little impact to
sharpness, especially under limited lighting condition. Besides, the
advanced 3DNR effectively decreases the band width and saves the
storage space.
Smart Illumination
The camera is designed with IR illumination for best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W
image under low illumination. Dahua’s unique Smart IR adjusts to the
intensity of 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.
Protection (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has
dust-proof function, and the enclosure can works normal after soaking
in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% (for some power supplies) input
voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.
