Series Overview With upgraded H.265 encoding technology, Dahua Lite series network camera has efficient video encoding capacity, which saves bandwidthand storage space
This camera adopts the latest starlight technology and displays better color image in the condition of low Illumination
Itsupports SD card storage, dust-proof function, waterproof functio andvandalprooffunction,complying with the standards of IP67
FunctionsSmart 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 transmissioWDR With advanced Wide Dynamic Range (WDR) technology, Dahua network camera provides clear details in the environment of strong brightnesscontrast
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 optical technology, Dahua Starlight technology can provide clear colorful video in the environment of low illuMinimumance
It widely applies to various environments of low illuMinimumance
IVS With advanced video algorithm, Dahua IVS technology supports intelligent functions, such as trIPwire and intrusionCyber Security Dahua network cameras employ a series of security technologies,including security authentication and authorization, access control protocols, trusted protection, encrypted transmission and encrypted storage
These technologies improve the camera's defense against external cyber threatsandpreventmalicious programs from compromising the deviceProtection (IP67, wide voltage) IP67: The camera passes a series of strict test on dust and soa
It has dust-proof function, and the enclosure can works normal after soakingin 1 m deep water for 30 Minimumutes
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
