The PTC-155 series HD PTZ cameras include the standard PTC-155 model and the HDBaseT-supported PTC-155T. The most difference between the PTC-155 series and previous Datavideo PTZ cameras is the addition of an auxiliary panoramic camera dedicated to automatic tracking, complementing the main lens. Both the main and auxiliary lenses use 1/2.8” CMOS sensors, providing a resolution of 1080p at 50/60 frames per second.
