Whenultra violet is used, once it hits a solid object form, it scans through it and show on a moniter whats inside it
Nope! Only when it is dark out.
With a ultraviolet light detector.
motion detector
Motion detector lights work by using sensors, such as infrared or microwave sensors, to detect changes in the environment caused by movement. When movement is detected, the sensors trigger the light to turn on and illuminate the area.
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 reset a motion detector light and restore its functionality, first turn off the power to the light at the circuit breaker. Wait for a few minutes, then turn the power back on. This should reset the motion detector and allow it to function properly again.
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.
