Wide detection range, but energy saving and safety design
The antenna consumes less than 10W of power.
The antenna covers a very wide area, but the strength of the antenna's electric field is less than 1/5 of Japan's radio law limit,
so the antennas have no effect on other electronic devices such as pacemakers which means the antenna is safe.
