Smart H.265+ & Smart H.264+

With an 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.

Wide Dynamic Range

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

Starlight

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

Intelligent Video Surveillance

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

Protection

IP67: The camera passes a series of strict test on dust and soak. It has a 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 an outdoor environment with unstable voltage.
