 Series Overview

With upgraded H.265 encoding technology, Dahua Lite series network
camera has efficient video encoding capacity, which saves bandwidth
and storage space. This camera adopts the latest starlight technology
and displays better color image in the condition of low illumination. It
supports SD card storage, dust-proof function, waterproof function and
vandal-proof function, complying with the standards of IP67 (Supported
by some select models).

Functions

1. Smart H.265+ & Smart H.264+
With advanced scene-adaptive rate control algorithm, Dahua smart
encoding technology realizes the higher encoding efficiency than H.265
and H.264, provides high-quality video, and reduces the cost of storage
and transmission.

2. WDR
With advanced Wide Dynamic Range (WDR) technology, Dahua network
camera provides clear details in the environment of strong brightness
contrast. The bright and dark area can get clear video even in high
brightness environment or with backlight shadow.

3. Starlight
With advanced image processing technology and optical technology,
Dahua Starlight technology can provide clear colorful video in 
the environment of low illuminance. It widely applies to various 
environments of low illuminance. 

4. IVS
With advanced video algorithm, Dahua IVS technology supports
intelligent functions, such as tripwire and intrusion.

5. Cyber Security
Dahua network camera is equipped with a series of key security
technologies, such as security authentication and authorization, access
control, trusted protection, encrypted transmission, and encrypted
storage, which improve its security defense and data protection, and
prevent malicious programs from invading the device. 

6. 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.
