The Hikvision DS-2CD3146G2-IS(2.8mm) dome camera with a 2.8mm lens offers 4MP high-definition images and a wide 101° field of view, ideal for monitoring indoor and outdoor spaces. Thanks to DarkFighter technology, it ensures excellent performance even in low-light conditions, while 120 dB WDR guarantees clear images even in backlighting. Deep learning-based AcuSense technology can distinguish people and vehicles, reducing false alarms. With IP67 and IK10 protection, IR illumination up to 40 meters and the HEOP platform for third-party application integration, it represents a reliable and professional security solution without audio recording.
Main features:
- 2.8mm fixed lens with 101° horizontal FOV
- 4MP resolution (2688×1520) with WDR 120 dB
- AcuSense AI with people/vehicle detection
- IR illumination up to 40 meters
- IP67 and IK10 vandal-proof protection
- HEOP function for custom applications
Further details
2.8mm wide-angle fixed lens with a 101° horizontal field of view, ideal for monitoring large spaces such as entrances, corridors or common areas, ensuring detailed and complete images.
1/3” CMOS sensor with up to 4MP (2688×1520) resolution and 120 dB WDR technology for clear and balanced images even in strong backlight conditions.
IP camera with support for main network protocols (TCP/IP, HTTP, HTTPS, RTSP, ONVIF, etc.), easily integrated with management software such as Hik-Connect and Hik-Central, for centralized control.
Basic and smart event management, including tampering detection, exceptions, scene change, abandonment or object removal, with the ability to send notifications, activate recordings or alarms.
Advanced function that detects motion by distinguishing people and vehicles, reducing false alarms caused by animals, leaves or variable weather conditions.
It includes perimeter protection (line crossing, intrusion, area entry/exit), face capture and people counting, leveraging deep learning algorithms for precise surveillance.
The Embedded Open Platform enables the integration of third-party applications, extending functionality and customizing security management.
Thanks to AI, it intelligently classifies targets by focusing on people and vehicles, increasing surveillance efficiency and reducing false alarms.
It ensures clear and bright images even in low light conditions (up to 0.003 Lux in color), making it ideal for night-time situations or poorly lit areas.
