System Overview

Dahua Pinhole series network camera includes one-in-all camera and

separated camera. Separated camera can work with dierent lens to
meet the requirements in dierent installaon scenes. Pinhole Series

camera is widely applied in hidden or small scenes such as banks and

adversing screen.

Funcons

Smart Codec

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.

Protecon (wide voltage)

Wide voltage: The camera allows ±30% input voltage tolerance (wide
voltage range), and it is widely applied to outdoor environment with
instable voltage.

WDR

Cyber Security

Dahua network camera is equipped with a series of key security tech-

nologies, 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.
