Product information

Dahua HUM4431S1-L4-AS-0280B pinhole IP camera 4MP, 2.8mm

4MP Fixed-focal Pinhole Network Camera-PoE

Smart H.265+ & Smart H.264+

With an advanced scene-adaptive bitrate control algorithm, Dahua smart encoding technology provides higher efficiency than H.265 and H.264. It ensures high-quality video while reducing storage and transmission costs.

WDR (Wide Dynamic Range)

Advanced WDR technology delivers clear image details even in environments with strong brightness contrast. Both bright and dark areas remain visible, even in backlight conditions.

Starlight

With advanced image processing and optical technologies, Dahua Starlight delivers clear, colorful video even in low-light environments. It is ideal for poorly lit areas.

Protection (Wide Voltage)

The camera supports ±30% input voltage tolerance, ensuring stable operation even in environments with unstable power supply, especially outdoors.

Cyber Security

Dahua network cameras use multiple security technologies, including authentication, access control, encrypted transmission, and secure storage. These features protect against cyber threats and unauthorized access.
