Motion detectors used on their own in a circuit, such as in an area
intrusion system or burglar alarm, will always work while the system is
armed.
Motion detectors used in conjunction with a day/night electric eye, of
the type used in outdoor floodlights, will work only when the electric eye
senses that the ambient light is low enough to turn on the floodlight. The
motion detector and the electric eye are in effect two switches wired in
series between the source power and the floodlight. If either switch is
open
then the floodlight remains off.

Agreed. So just bypass the electric eye and it will work 24/7 4 U.
