With powerful optical zoom, light sensitive sensor and precise pan / tilt / zoom performance, the PTZ Dome offers a large surveillance area and great details

The camera delivers a resolution of 1080P at 25 frames per second. The PTZ Dome is equipped with smooth control, high image quality and good protection and meets the requirements for compact sizes of video surveillance applications.

Starlight technology

For demanding low-light applications, Dahua's Starlight Ultra-Low Light technology offers the best light sensitivity in its class and captures color details in low-light conditions down to 0.005 lux. The camera uses a number of optical functions to compensate for the light throughout the scene and get clear images in dark environments.

A large dynamic range

With the industry-leading WDR technology (Wide Dynamic Range), the camera achieves vivid images even in the most intense contrast lighting conditions. For applications with bright and poor lighting conditions that change quickly, True WDR (120 dB) simultaneously optimizes the light and dark areas of a scene to provide usable video.

Smart H.265 +

Smart H.265 + is the optimized implementation of the H.265 codec, which uses a scene-adaptive coding strategy, a dynamic GOP, a dynamic ROI, a flexible multi-frame reference structure and intelligent noise reduction to deliver high quality videos without strain the network. H.265 + technology reduces bit rate and memory requirements by up to 70% compared to standard H.265 video compression.

PFA technology

PFA technology has innovatively introduced new assessment methods to ensure the accuracy and predictability of the direction of object distance setting. The result is a series of advanced focusing algorithms.

PFA ensures clarity of the image throughout the zoom and shortens the focus time. The implementation of PFA technology significantly improves the user experience and increases the product value.

Overvoltage protection

The PTZ Dome enables a flash output of 6 kV, which effectively protects both the camera and its structure from lightning. Interoperability The camera complies with the ONVIF (Open Network Video Interface Forum) specifications and ensures interoperability between network video products regardless of the manufacturer.

Best night vision with infrared

The built-in IR night vision LEDs ensure homogeneous and far-reaching illumination of the scene. The range of the high-performance LED is up to 100 meters. Due to the IR spectrum, which is above the color spectrum, the videos are displayed in black and white during the night. If the videos are also to be displayed in color at night, the use of white light emitters is recommended.

Other features:

- Integrated video analysis

- Weatherproof outer casing

- Wall arm included in the scope of delivery

- Input and output contacts for audio and alarm
