IntroductionParameters

Product Introduction

Enhanced image clarity: Featuring a large sensor area and an ultra-wide aperture lens design to maximize light transmission, combined with AI-ISP's advanced noise reduction technology, the system delivers fivefold improved low-light performance and full-color imaging in dim environments.

l supports ICR infrared filter switching for true 24/7 monitoring.

MIPI: Leveraging the real-time performance and high bandwidth efficiency of the MIPI interface, it enables real-time transmission of 4MP@60fps lossless video data.

l Network: 10M/100M adaptive network interface, supporting video output up to 4MP@60fps.

 Gyroscope image stabilization: This feature effectively stabilizes footage and reduces shaking in common vibration environments.

l Focus Stability: The system features built-in temperature compensation technology, ensuring stable and rapid focusing performance even under varying temperatures.

l Fog-Resistant Imaging: Optically transparent to penetrate fog and haze, providing comprehensive monitoring coverage with no blind spots and a visual range enhanced by 1.7 times.

l Wide Dynamic Range: Features built-in strong light suppression, backlight compensation, and wide dynamic range modes effortlessly handling any lighting scenario.

Perimeter Detection: Features a comprehensive suite of intelligent video analysis capabilities, including area intrusion detection, abnormal behavior detection, and integrated smart tracking.

l Target Recognition: Equipped with a deep learning-based algorithm for identifying people, vehicles, and fireworks, enabling comprehensive and advanced applications in intelligent security protection.

The7  instantly switches between wide-angle and telephoto modes with seamless zoom performance, maintaining sharp image quality throughout for consistent tracking accuracy.

The stepper motor boasts a service life of 1 million cyclesfive times that of conventional brushless DC motorsand is ideal for applications requiring frequent zooming and focusing, such as anti-drone systems.

 supports the VISCA/PELCO protocols, enabling easy control of devices and turntables.

l supports GB28181/ONVIF standards, enabling seamless integration with mainstream platforms.

l Supports HTTP CGI and can integrate with third-party platforms.

With a compact size of just 178 mm and a weight of 970 g, it significantly reduces the load requirements on the pan-tilt unit, thereby lowering both its cost and installation expenses.
