Who invented motion detectors?
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.
How can pistons that move up and down generate electricity?
The reciprocating motion of the pistons is converted into rotary motion which is connected to a shaft connected to an electrical generator .
Components of electro optical system?
There are several components of an electro-optical system. These include an EOS detector, position detectors, color detectors, and quadrants.
Does your computer need to be connected to a LAN to view an HTML document on a website?
Your computer must be connected to the internet to view an HTML document that is located on a website. Whether that connection is through a local area network (LAN) or not. If you normally connect to the web via the LAN, then yes, you'll need to be connected to the LAN. If instead you run an adhoc network, use a direct connection to infrastructure (like a router) or a modem, then you need that connection to reach the web.

What is the impact motion detectors have on society?
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.
What brand of motion detectors have the the greatest range?
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.

Are cctv securrity cameras also motion detectors?
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.
Do wired smoke detectors mount on electrical boxes?
Hard wired smoke detectors have to have a junction box behind them. These detectors use 120 volts as a working voltage. These types of detectors should be wired with 3 conductor #14 wire. The detector uses the black and white wires for the 120 volt source. Detectors these days have an output signal wire that can be connected to other detectors so that if one trips it will sound the alarm in other detectors that are on the same circuit. This output wire can be connected to other detectors by the third red wire in the 3 conductor cable.
Are there cameras in fire detectors?
Yes. The latest technology Smoke detector IP cameras are integrated with both functions of smoke detector and IP camera. It helps to monitor your home or office from any part of the world. It can be connected to a WiFi network and when a motion is detected, it will send the live videos and images to User's mobile or computer.
