Which of the following lists includes only volumetric sensors?
Which of the following lists includes only volumetric sensors?
Volumetric sensors are designed to detect changes within a volume of space rather than at a specific point. Among the given lists, the combination of video motion, magnetic field, and microwave sensors fits this definition. Video motion sensors detect movement within a visual field, magnetic field sensors detect changes in magnetic fields which can occur within a volume of space, and microwave sensors use microwave radar to detect motion within a defined area.
Fiber optic cable is not Volumetric
It is C.
A, cz video motion is not volumetric
