Functions

Starlight+ Technology
Dahua’s Starlight Ultra-low Light Technology excels in low-light conditions, offering superior light sensitivity and capturing color details down to 0.002 Lux. The camera’s optical features balance light across the scene, ensuring clear images even in dark environments.

Face Recognition
Captured facial features are extracted and stored in a database for easy searching and comparison with other images. When a match is found, the system provides the result. The Dahua Face Recognition camera includes a built-in database capable of storing up to 10,000 facial images, facilitating real-time face capture and comparison.

Perimeter Protection
The system filters out false alarms triggered by animals, rustling leaves, bright lights, and other sources. This allows for secondary recognition of targets, thereby improving alarm accuracy.

Metadata
Metadata provides detailed attribute information about target objects for data retrieval. Dahua PTZ AI cameras support four types of metadata: human face, human body, motor vehicle, and non-motor vehicle. Facial metadata includes attributes such as gender, age, glasses, masks, and beards. Human body metadata covers items like hats, tops, and bottom color. Motor vehicle metadata includes plate color, type, vehicle color, and other features. Non-motor vehicle metadata includes type, color, and the number of people, among other attributes.

PFA Technology
PFA technology employs advanced methods to enhance the accuracy and predictability of subject distance adjustments, utilizing sophisticated focusing algorithms. It ensures image clarity during zooming and reduces focus time, thereby improving user experience and product value.

Environment
Dahua cameras are designed for extreme temperatures, operating within a range from -40 °C to +70 °C (-40 °F to +158 °F) and 95% humidity. They undergo rigorous dust and water immersion tests and are certified to the IP67 Ingress Protection rating, making them suitable for demanding outdoor environments.

Protection
The camera supports ±25% input voltage tolerance, making it resilient to unstable outdoor conditions. It also features an 8KV lightning rating, providing effective protection against lightning for both the camera and its structure.

Interoperability
The camera adheres to ONVIF (Open Network Video Interface Forum) specifications, ensuring compatibility and interoperability with network video products from various manufacturers.
