4K 40x network video camera Starlight PTZ Dahua DH-SD8A840WA-HNF
Dahua AI series products use the most advanced artificial intelligence (AI) technologies, including deep learning algorithms that are used to recognize vehicles and people.
The Dahua AI series supports various types of security solutions with many advanced features, including facial recognition, ANPR, metadata collection and analysis, human counting, image search, face flow, traffic accident detection, and statistical analysis of traffic data.
The full line of Dahua AI includes network PTZ video cameras, network video recorders, servers, management platforms, etc. In addition to observing the world, deep learning capabilities using AI allow devices to find the best path to complete their tasks, offering greater flexibility and accuracy for end users.
The Dahua PTZ AI network camera uses advanced CNN deep learning algorithms to support facial recognition with high accuracy. This camera features a wide range of monitors, a PFA algorithm that can always display a clear, focused image when zoomed in, and intelligent windshield wiper technology supported by RainSensor.
The facial features obtained from captured faces are stored in a database where they can be easily searched and compared with other images. After a successful match, the system outputs the result. The camera's memory holds up to 10,000 faces, allowing you to capture and compare faces in real time.
Thanks to starlight technology from Dahua, the camera is ideal for working in difficult conditions with limited lighting. Its low light sensitivity ensures the performance of a color image with minimal ambient lighting. Even in extreme low-light conditions, almost in total darkness, Starlight technology is able to display a color image.
Automatic filtering of false alarms caused by animals, rustling leaves, bright lights, etc. Allows the system to perform secondary target recognition. Increasing the accuracy of signaling.
PFA (Predictive Focus Algorithm) introduces a new method to achieve continuous high-precision focusing throughout the entire zoom process. PFA technology has introduced new methods for estimating accuracy and calculating the distance to any object that falls into the frame. This is also due to a set of completely new developed focusing algorithms. PFA provides image clarity throughout the entire zoom process and reduces focus time.
Metadata is an object attribute information extracted from the target object that can be used to retrieve data. There are four types of metadata supported by the Dahua PTZ AI camera: metadata of a person's face, a person's body, a car, and a non-motorized vehicle. Face information includes gender, age, glasses, mask, beard, and so on. Information about a person's body includes hat, top, top color, bottom, bag availability, and so on. Car information includes color, type, sun visor, pattern, seat belt, Smoking, annual inspection sticker, etc.
Information about non-motor vehicles includes the type, color, top type, top color, number of people, and so on.
Dahua cameras operate in extreme temperature conditions, designed for use at temperatures from -40 ° C to 70 ° C (-40 ° F to 158 ° F) with 95% humidity. The camera meets the IP67 protection standard, which makes it capable of being subjected to severe environmental conditions.
The camera supports input voltage protection of ±25%, suitable for operation in unstable power conditions that can occur in outdoor applications. Also, the device has a built-in lightning protection of 8 kV, which is designed to preserve the structure of the camera during thunderstorms.
The camera meets the ONVIF (Open Network Video Interface Forum) and PSIA (Physical Security Interoperability Alliance) specifications, which ensure interaction between network video products regardless of the manufacturer.
