Network

System Overview
With upgraded H.265 encoding technology, Dahua Lite series camera has
efficient video encoding capacity, which saves bandwidth and storage
space. This camera adopts the latest starlight technology and displays
better colorful image in the environment of low illumination. It supports
SD card storage, waterproof function, dust-proof function, complying to
the standards of IP67.
Functions
Smart ( H.265+ & H.264+ )
Adopting advanced algorithm of auto stream control according to the
environment, Dahua smart encoding technology realizes the higher efficiency 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 illumination, and it can provide clear colorful video. Even in the environment
of min. illumination, the technology can guarantee the good image effect.
Intelligent Video Analysis (IVS)
With advanced video algorithm, Dahua camera supports intelligent detection, such as tripwire and intrusion and so on.
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% input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable
voltage.
