The setting's three choices are Default/Assist/Replace, but the description
text described the "Assist" behavior using the literal word "Filter" instead
of interpolating BUILTIN_MOTION_SENSOR_ASSIST — no such option exists, which
is confusing since this setting controls a real, consequential choice
(whether Scrypted's own motion detection replaces or just verifies the
camera's built-in sensor).
