La Dahua PTZ85848-HNF-PA es una cámara PTZ de posicionamiento avanzado diseñada para entornos de seguridad exigentes como aeropuertos, fronteras, zonas industriales o centros logísticos. Su sensor STARVIS™ CMOS de 1/1.8” captura video en 8 megapíxeles con una claridad excepcional tanto de día como de noche.
Características destacadas:
Resolución 8MP (25/30 fps) – Video de ultra alta definición en tiempo real
Zoom óptico 48x – Seguimiento detallado a grandes distancias sin pérdida de calidad
Tecnología Starlight + IR – Imágenes en color en condiciones de poca luz y visión nocturna IR hasta 400 metros
Codificación H.265 – Compresión eficiente sin sacrificar calidad
Audio bidireccional – Comunicación en tiempo real con los sitios monitoreados
Protección perimetral inteligente – Análisis de cruce de línea, intrusión, detección de objetos abandonados, etc.
Auto-tracking – Seguimiento automático de objetivos en movimiento
Reconocimiento facial – Tecnología de análisis facial incorporada
Grado de protección IP67 – Resistente al agua, polvo y condiciones adversas
Sistema de posicionamiento WizMind – Alta precisión, velocidad y rango de rotación
Esta cámara PTZ es ideal para vigilancia urbana, protección de infraestructura crítica y monitoreo de grandes perímetros, combinando rendimiento óptico y analítica inteligente en un solo equipo.
