"IUS014F-Z" is an all-in-one imaging module type with a camera signal processing functions on the image sensor, with built-in auto-focus and image quality adjustment.
"AF Limit Mode" can adjust the range of auto focusing and "Shutter Priority AF" offers faster focus adjustment by stopping the live view to increase the speed of the auto focusing.
In exchange for a more substantial energy-bill savings (5-10% of the summer's air-conditioning tariff), participating customers agree to an "Auto-Tune" of their Nest, a three-week adjustment period where the algorithms plan a regime that routinely rejiggers air-conditioning use during the day.
