Activity Controlled Framerate (ACF)
This is a powerful feature, unique to IndigoVision devices. Using their built-in analytics capability, IP cameras and Transmitters constantly monitor the amount of motion between frames. When there is no motion in the scene, the frame rate is reduced to one frame per second. When motion occurs, the frame rate is instantly increased to the maximum specified by the user. This can reduce data rates by up to 50-fold, which increases the amount of video that can be stored on an NVR.
