Functions

Starlight Technology Dahua’s Starlight Ultra-low Light Technology excels in low-light environments, providing exceptional light sensitivity and capturing color details down to 0.005 lux. The camera features advanced optical systems that balance light across the scene, ensuring clear images even in dark conditions.

Wide Dynamic Range Using industry-leading Wide Dynamic Range (WDR) technology, the camera delivers vivid images in high-contrast lighting situations. True WDR (120 dB) optimizes both bright and dark areas of a scene simultaneously, making it ideal for environments with rapidly changing lighting conditions.

Perimeter Protection The camera effectively filters out false alarms caused by animals, rustling leaves, and bright lights. This enhances alarm accuracy by allowing the system to focus on secondary recognition of targets.

Environmental Designed for extreme temperatures, Dahua cameras operate reliably in conditions ranging from -40 °C to +70 °C (-40 °F to +158 °F) and 95% humidity. They undergo stringent dust and water immersion tests and are certified to IP66 Ingress Protection, making them suitable for demanding outdoor use.

Protection With a 6KV lightning rating, the camera is well-protected against lightning strikes, safeguarding both the camera and its structural components.

Interoperability The camera adheres to ONVIF (Open Network Video Interface Forum) standards, ensuring compatibility with various network video products regardless of the manufacturer.

PFA Technology PFA technology introduces advanced focusing algorithms for precise and predictable adjustment of subject distance. It enhances image clarity throughout the zoom process and reduces focus time, significantly improving user experience and product value.

SMD PLUS Utilizing a deep-learning algorithm, Dahua SMD PLUS effectively filters motion detection alarms to reduce false alerts. It distinguishes between human and vehicle movements, sending alarms only for relevant intrusions.

4G Transmission The camera supports 4G signal transmission and is compatible with LTE, WCDMA, and GSM network types. It operates on the following frequencies:

• LTE FDD: Band 1/2/3/4/7
• WCDMA: Dual-band Band 1/2
• GSM: 1800 MHz/1900 MHz
