Series Overview

With upgraded H.265 encoding technology, Dahua Lite series network
camera has ecient video encoding capacity, which saves bandwidth
and storage space. This camera adopts the latest starlight technology
and displays beer color image in the condion of low illuminaon. It
supports SD card storage, dust-proof funcon, waterproof funcon and
vandal-proof funcon, complying with the standards of IP67 (Supported
by some select models).

Funcons

Smart H.265+ & Smart H.264+

With advanced scene-adapve rate control algorithm, Dahua smart
encoding technology realizes the higher encoding eciency than H.265
and H.264, provides high-quality video, and reduces the cost of storage

and transmission.

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.

Starlight

With advanced image processing technology and opcal technology,
Dahua Starlight technology can provide clear colorful video in

the environment of low illuminance. It widely applies to various
environments of low illuminance.

IVS

With advanced video algorithm, Dahua IVS technology supports
intelligent funcons, such as tripwire and intrusion.

Cyber Security

Dahua network camera is equipped with a series of key security
technologies, such as security authencaon and authorizaon, access
control, trusted protecon, encrypted transmission, and encrypted
storage, which improve its security defense and data protecon, and
prevent malicious programs from invading the device.

Protecon (IP67, wide voltage)

IP67: The camera passes a series of strict test on dust and soak. It has
dust-proof funcon, and the enclosure can works normal aer 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.
