Functions

Starlight Technology
Dahua’s Starlight Ultra-low Light Technology excels in challenging low-light scenarios, delivering superior light sensitivity and capturing color details with illumination levels as low as 0.005 lux. The camera integrates advanced optical features to balance light across the entire scene, producing clear images even in dark environments.

Wide Dynamic Range
The camera utilizes cutting-edge Wide Dynamic Range (WDR) technology to produce vivid images under high-contrast lighting conditions. True WDR (120 dB) effectively manages both bright and dark areas of a scene simultaneously, ensuring clear video in rapidly changing light conditions.

Auto-tracking
The auto-tracking feature manages the camera’s pan, tilt, and zoom functions to follow a moving object and keep it within view. This tracking can be initiated manually or triggered automatically based on predefined rules. When activated, the camera zooms in and tracks the designated target autonomously.

Smart H.265+
Smart H.265+ represents an enhanced version of the H.265 codec, utilizing a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structures, and intelligent noise reduction. This optimization provides high-quality video while 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 subject distance adjustments. This results in sophisticated focusing algorithms that ensure image clarity throughout zooming and shorten the focus time, greatly enhancing user experience and product value.

Environmental
Dahua cameras are designed to perform in extreme temperatures ranging from -40°C to 70°C (-40°F to +158°F) and can withstand 95% humidity. They meet the IK10 Vandal Resistance impact rating and have passed rigorous dust and water immersion tests, earning the IP67 Ingress Protection rating, making them suitable for demanding outdoor environments.

Protection
The camera features an 8KV lightning rating, offering robust protection against lightning strikes for both the camera and its structural components.

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