The first motion detector was invented by Russian Leon Theremin in the year 1920, but the first motion detectors used as a security device were developed in early 1950's by Samuel Bagno. The basis of these first detectors was the Doppler effect and ultrasonic waves application.

There are several components of an electro-optical system. These include an EOS detector, position detectors, color detectors, and quadrants.
Short time after photo cameras have been invented, people started thinking of making motion pictures - and invented cinema based on the same technological principle.
Metal detectors work by emitting electromagnetic signals outward. When those electromagnetic signals bounce back to the receiver, the machine knows that there is an object in that location and alerts the user.
Thomas Newcomen in 1712. James Watt expanded on this technology in 1781 to allow for Rotary Motion. Having said this the first Steam powered Locomotive was first released in 1812
Motion detectors are: infrared detectors, ultrasonic, microwave, radiowave and... dogs.
technology that makes use of motion detectors
Motion detectors have had a massive impact on today's society. Motion detectors have made life easier for those who are very busy for example.
There are many levels of long range motion detectors, personal use and commercial use. Some motion detectors can detect movement up to 8-10 miles away. Some good brands for long range motion detectors are Honeywell and KNX.
Yes
Smoke detectors were invented in the year 1967. :P

Some cctv security cameras also have motion detectors. If you are looking for a security camera with this feature, you should check the description before you buy it.
home security, motion detectors, have weapons near
No. They were not invented yet.
