What is AHD and what is HD-SDI?（Resolution）
Answer
Both AHD and HD-SDI have a resolution of 1920×1080.
AHD: Analog High-definition
HD-SDI: High Definition-Serial Digital Interface (a video standard using the existing broadcast standard)
Since AHD and HD-SDI use different methods, when recording video, use equipment with the same method for the camera and recording equipment.
