Functions

Starlight Technology
For challenging low-light scenarios, Dahua’s Starlight Ultra-low Light Technology delivers exceptional light sensitivity, capturing color details in lighting conditions as low as 0.005 lux. The camera utilizes advanced optical features to balance light across the scene, ensuring clear and detailed images even in dark environments.

Wide Dynamic Range
The camera produces vivid images in extreme lighting conditions using leading-edge wide dynamic range (WDR) technology. True WDR (120 dB) optimizes both bright and dark areas simultaneously, making it ideal for scenes with rapidly changing lighting conditions.

Auto-tracking
This feature enables the camera to automatically track moving objects by controlling its pan, tilt, and zoom functions. Tracking can be activated either manually or through predefined rules. Once a rule is triggered, the camera automatically zooms in and follows the designated target.

Smart H.265+
Smart H.265+ is an enhanced version of the H.265 codec, employing a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction. This technology achieves high-quality video while minimizing network strain, reducing bit rate and storage needs by up to 70% compared to standard H.265 compression.

PFA Technology
PFA technology introduces advanced judgment methods for precise and predictable adjustments of subject distance. It features sophisticated focusing algorithms that ensure image clarity throughout the zoom process and shorten focus times. PFA technology significantly enhances user experience and adds value to the product.

Environmental
Dahua cameras are designed to function in extreme temperatures, with operational ranges from -30°C to 60°C (-22°F to +140°F) and 95% humidity. They also comply with the IK10 Vandal Resistance impact rating, ensuring durability in harsh environments.

Protection
The camera supports ±10% input voltage tolerance, making it suitable for outdoor applications with unstable power conditions. Additionally, it has a 6KV lightning rating, providing robust protection against lightning strikes for both the camera and its structure.

Interoperability
The camera adheres to ONVIF (Open Network Video Interface Forum) standards, guaranteeing compatibility and seamless integration with network video products from various manufacturers.
