Re: Quiet, 24VDC Motion Detector?

[Robert L Bass <sales@xxxxxxxxxxxxxxxxxxxxx>]

Lincoln,

There are hundreds of inexpensive motion detectors available.
Only a few of them work with 24 VDC.  Most are designed for 12
VDC.  Several of the models I sell online can handle 9~16 VDC but
none are rated for 24V.
