Smart H.265+ & Smart H.264+

Utilizing advanced scene-adaptive rate control algorithms, Dahua's smart encoding technology achieves higher encoding efficiency than standard H.265 and H.264, delivering high-quality video while reducing storage and transmission costs.

WDR

With advanced Wide Dynamic Range (WDR) technology, the camera captures clear details in environments with strong brightness contrast, providing clear video even in high brightness or backlight shadow conditions.

Starlight

Dahua's Starlight technology, combined with advanced image processing and optical technology, delivers clear, colorful video in low-illuminance environments, making it suitable for various low-light applications.

IVS (Intelligent Video System)

The IVS technology supports intelligent functions such as tripwire and intrusion detection.

Cyber Security

The camera incorporates key security technologies including security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage to enhance data protection and prevent unauthorized access. It holds UL CAP Certification, TÜV Rheinland Protected Privacy IoT Product Certification, and ETSI EN 303645 Certification, meeting demands for cyber security and privacy protection.

Protection (IP67, IK10, Wide Voltage)

IP67: The camera is dust-proof and can operate normally after being immersed in 1 m deep water for 30 minutes.

IK10: The enclosure can withstand a punch from a 5 kg hammer falling from a height of 40 m (Impact energy of 20J).

Wide Voltage: The camera tolerates input voltage variations of ±30% (for certain power supplies), making it suitable for outdoor environments with unstable voltage.
