Technical Context
The AVC-NKB81M50 is built for long range license plate recognition and detailed outdoor monitoring where both resolution and lens reach are important. Its motorized 5-50mm lens allows installers to adjust the field of view for vehicle lanes, gates, driveways, and other controlled access points, while H.265 compression helps reduce bandwidth and storage usage.
Installation Notes
This camera supports DC12V or PoE power supply for flexible installation. The IP67-rated housing is suitable for outdoor environments, and remote monitoring is supported through the AVYCON ONE mobile app and AVYCON CMSONE CMS.
