Further details
The 2.8mm wide-angle fixed lens offers a very wide field of view (101° horizontal) , ideal for monitoring large areas such as perimeters, entrances and open spaces, ensuring complete and detailed coverage.
The Progressive Scan CMOS sensor ensures high definition 4MP (2688×1520) images, allowing a clear and precise vision even for the analysis of the smallest details.
The vehicle detection function allows for precise monitoring of cars and vehicles in transit, ideal for parking lots, access points and sensitive areas.
Motion detection is optimized by AI to trigger alarms only when significant events occur, increasing operational efficiency.
Deep learning features include perimeter protection with intrusion and line crossing detection, with targeted classification of people and vehicles.
Support for the main professional network protocols (ONVIF, TCP/IP, HTTPS, RTSP, IPv4/IPv6) ensures maximum compatibility and integration with IP video surveillance systems.
