Functions

Starlight Technology
For challenging low-light conditions, Dahua’s Starlight Ultra-low Light Technology delivers superior light sensitivity, capturing color details in lighting as low as 0.005 lux. The camera employs a set of optical features to evenly distribute light across the scene, ensuring clear images even in very dark environments.

Wide Dynamic Range
The camera produces vibrant images even under extreme contrast lighting conditions, thanks to advanced wide dynamic range (WDR) technology. True WDR (120 dB) manages both bright and dark areas simultaneously, providing clear and usable video in scenes with rapidly changing light levels.

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

Environmental
Dahua cameras are designed to function in extreme temperatures, operating within a range of -30 °C to +60 °C (-22 °F to +140 °F) and 95% humidity. The camera meets the IK10 Vandal Resistance rating, capable of withstanding impacts equivalent to 55 kg (120 lbs). With an IP66 rating, it is thoroughly tested for dust and water resistance, making it suitable for demanding outdoor environments.

Protection
The camera supports a ±10% input voltage tolerance, accommodating unstable outdoor power conditions. It is equipped with a 2KV lightning rating to safeguard both the camera and its structure from lightning strikes.

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