Functions

Perimeter Protection
The system automatically filters out false alarms caused by animals, rustling leaves, bright lights, and other non-threatening elements. It enhances target recognition and significantly improves alarm accuracy.

Starlight+ Technology
Dahua’s Starlight Ultra-low Light Technology is designed for low-light applications, providing exceptional light sensitivity. It captures color details in lighting conditions as low as 0.001 lux and uses advanced optical features to balance light across the scene, resulting in clear images even in dark environments.

PFA Technology
PFA technology introduces innovative methods to ensure precise and predictable subject distance adjustments. This advanced focusing technology delivers clear images throughout the zoom process and reduces focus time, significantly enhancing user experience and product value.

Environmental
Dahua cameras are built to withstand extreme temperatures, operating effectively in environments ranging from -40 °C to +70 °C (-40 °F to +158 °F) with up to 95% humidity. They are rigorously tested for dust and water resistance and are certified with an IP67 Ingress Protection rating, making them ideal for challenging outdoor conditions.

Wide Dynamic Range
The camera utilizes industry-leading wide dynamic range (WDR) technology to produce clear images even in high-contrast lighting situations. True WDR (120 dB) optimizes both bright and dark areas of a scene simultaneously, ensuring usable video in rapidly changing light conditions.

Auto-tracking
This feature automatically controls the camera's pan, tilt, and zoom functions to track moving objects within the scene. The tracking can be initiated manually or automatically based on predefined rules, allowing the camera to zoom in and follow the target automatically.

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

SMD PLUS
Powered by a Deep-Learning Algorithm, Dahua SMD PLUS effectively filters out non-essential motion detection alarms, accurately recognizing and sending alerts for human and vehicle intrusions.
