System Overview
With upgraded H.265 encoding technology, Dahua Lite series camera has
ecient video encoding capacity, which saves bandwidth and storage
space. This camera adopts the latest starlight technology and displays
beer colorful image in the environment of low illuminaon. It supports
SD card storage, waterproof funcon, dust-proof funcon, complying to
the standards of IP67.
Funcons
Smart ( H.265+ & H.264+ )
Adopng advanced algorithm of auto stream control according to the
environment, Dahua smart encoding technology realizes the higher eciency than (H.265 & H.264 ), providing high-quality video, and reducing
the cost of storage and transmission.
Wide dynamic range (WDR)
Dahua adopts advanced Wide Dynamic Range (WDR) technology. You
can get clear details in the environment of strong brightness contrast.
In high brightness and back- light environment, bright region and dark
region with strong light source, you can also get clear images.
Starlight
Dahua Starlight technology mainly applies to the environment of low
illuminaon, and it can provide clear colorful video. Even in the environment of min. illuminaon, the technology can guarantee the good
image eect.
Intelligent Video Analysis (IVS)
With advanced video algorithm, Dahua camera supports intelligent
detecon, such as tripwire and intrusion and so on.
Protecon (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has
dust-proof funcon, and the enclosure can works normal aer soaking
in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% input voltage tolerance (wide
voltage range), and it is widely applied to outdoor environment with
instable voltage.
