motion detector
Motion lights will work during the day, but won't be practical in daylight when everything is already well-lit.
Yes, and you wouldn't need the motion detector.
The first motion detector was invented in the early 1950s by Samuel Bagno. He developed a device that could detect motion using a technology called ultrasonic waves. This early version of a motion detector paved the way for the more advanced versions we use today.
That's easy. Motion
Sonic detectors pick up sound waves and motions When things move, they often create changes in surrounding Read more: How Does a Sonic Motion Detector Work? | eHow.com http://www.ehow.com/how-does_4564490_sonic-motion-detector-work.html#ixzz1R9OT0diL not all written by me
The motion detection device was invented by Samuel Bagno in the early 20th century. He developed the first motion detector to detect intruders by sensing their movement.
It's called a "Motion Detector"!
To wire a motion detector with three-way switching, connect the motion detector to the common terminal of one switch. Then, connect the traveler wires from that switch to the common and traveler terminals of the other switch. Lastly, connect the motion detector to the common terminal on the second switch. This setup allows you to control the motion detector from both switches.

A cobra detector is a radar detector. Radar detectors work the same way a radio receiver does. The radar detector looks for frequencies that a radar gun uses.
