Series Overview
With upgraded H.265 encoding technology, Dahua Lite series network
camera has ecient video encoding capacity, which saves bandwidth
and storage space. This camera adopts the latest starlight technology
and displays beer color image in the condion of low illuminaon. It
supports SD card storage, dust-proof funcon, waterproof funcon and
vandal-proof funcon, complying with the standards of IP67 (Supported
by some select models).
Funcons
Smart H.265+ & Smart 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.
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 opcal 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
funcons, such as tripwire and intrusion.
Cyber Security
Dahua network camera is equipped with a series of key security technologies, such as security authencaon and authorizaon, access control,
trusted protecon, encrypted transmission, and encrypted storage, which
improve its security defense and data protecon, and prevent malicious programs from invading the device. With UL CAP Cercaon, TÜV
Rheinland Protected Privacy IoT Product Cercaon, and ETSI EN 303645
Cercaon, Dahua network camera beer meets the demands of cyber
security and privacy protecon.
Protecon (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has dustproof 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.
