DS-2CD2T43G2-4I(6mm) – ACUSENSE 4MP 6MM FIXED LENS BULLET NETWORK CAMERA

The Hikvision DS-2CD2T43G2-4I(6mm) camera with a 6mm fixed lens offers 4MP resolution and AcuSense AI technology to distinguish people and vehicles, reducing false alarms. Thanks to 120 dB WDR, H.265+ compression and IP67 protection, it guarantees clear images and reliable security even in difficult conditions, with IR illumination up to 80 meters. A professional solution ideal for outdoor use, easy to integrate into modern video surveillance systems.
Main features:
- 4MP resolution with 1/3″ CMOS sensor
- 6mm fixed lens (52° horizontal FOV)
- AcuSense AI technology for people/vehicle detection
- WDR 120dB and 3D DNR for clear images
- IR up to 80m for advanced night vision
- IP67 protection against water and dust
Further details
The 6mm fixed lens offers a 52° horizontal field of view, ideal for monitoring specific areas with greater precision and detail. It's perfect for monitoring entrances, parking lots, and perimeter areas where a targeted view is required.
Thanks to the 1/3” CMOS sensor and the maximum resolution of 4MP (2688×1520) , the camera guarantees clear and defined images, with 120 dB WDR technology that ensures optimal quality even in backlighting or in the presence of strong light contrasts.
This is a professional IP camera with support for major protocols (TCP/IP, HTTP, HTTPS, FTP, RTSP, NTP, IPv6, etc.), compatible with Hik-Connect and Hik-Central software, for simple and secure integration into network systems.
It manages intelligent events such as intrusion detection , face detection , line crossing detection , and sends real-time notifications. Actions can include uploading to FTP, triggering recording, taking snapshots, or sending alerts to the surveillance center.
The motion detection feature integrates AI algorithms that distinguish people from vehicles, drastically reducing false alarms caused by rain, animals, or blowing leaves. This improves safety and reduces response times.
Powered by deep learning, AcuSense technology takes video analytics to the next level, with intelligent object classification and targeted alarms. This enables reliable and precise control, optimizing surveillance in both commercial and residential environments.
