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+

Adopng advanced algorithm of auto stream control according to the
environment, Dahua smart encoding technology realizes the higher e­ciency than (H.265 & H.264 ), providing high-quality video, and reducing

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. With UL CAP Cercaon, TÜV
Rheinland Protected Privacy IoT Product Cercaon, and ETSI EN 303645
Cercaon, Dahua network camera beer meets the demands of cyber
security and privacy protecon.

Protecon (IP67, wide voltage)

IP67: The camera passes a series of strict test on dust and soak. It has dust­proof 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% input voltage tolerance (wide
voltage range), and it is widely applied to outdoor environment with
instable voltage.
