What is a motion sensor?
A motion sensor or detector is a kind of futuristic device. It can detect any rapid motion nearby. A motion sensor is a device that detects moving objects, mainly people. A motion sensor is often integrated into a system that regularly performs a task or alerts a user of movement in a region. These sensors are a very important element of safety, home control, locks, energy efficiency, automated lighting control and other useful systems. The basic principle of the motion detector is to detect a burglar and send an alert to your control panel, which sends an alert to your monitoring center. Motion sensors respond to different situations such as movement in your living room, doors, unlocking or closing windows. These sensors can also activate the buzzer when someone approaches the front door. These sensors alert you when children enter restricted areas of the home, such as a medicine cabinet, basement or weight room. Save energy by using this light sensor in empty spaces. There are many types of motion sensors. Different types of motion detectors are described in the following sections.

Passive infrared sensor (PIR)
All warm-blooded animals produce infrared radiation. Passive infrared sensors include a thin pyroelectric film, which reacts to infrared radiation by emitting electricity. This sensor will activate the anti-theft alarm whenever this influx of electricity takes place. These sensors are economical, do not use more energy and last forever. These sensors are commonly used in indoor alarms.
The ultrasonic sensor can be a passive passive (or passive) sensor paying particular attention to sounds such as metal on metal, broken glass. These sensors are very sensitive, but they are often expensive and subject to false alarms. The assets generate ultrasonic waves (sound waves), then determine the reflection of these waves on a moving object. Animals like cats, dogs and fish can hear these sound waves. An active ultrasonic alarm can destabilize them.
These sensors generate microwave pulses and then calculate their reflection on the objects, to know if the objects move or not. Microwave sensors are very sensitive, but can sometimes be seen in non-metallic objects, which can detect moving objects that are outside the target range. It consumes a lot of energy, so these sensors are often designed to be turned on and off. This allows you to acquire the past, if you know the cycles. Electronic watchdogs use microwave sensors.
Video camera software
With the proliferation of inexpensive digital cameras capable of filming video, it is possible to use the output of such a camera to detect motion in its field of view using software. This solution is particularly interesting when the goal is to record a video triggered by motion detection, no hardware other than the camera and the computer is needed. As the observed field can be illuminated normally, this can be considered as another passive technology. However, it can also be used with near infrared illumination to detect motion in the dark, i.e., with illumination at a wavelength undetectable by a human eye.
Immune movement sensors for pets
A passive infrared sensor can be configured to ignore animals up to a certain weight. A dual technology motion sensor is more resistant to false alarms caused by animals because it requires the triggering of two sensors in the manner determined by the manufacturer. They can be configured to ignore a large animal or multiple small animals without triggering a false alarm. Some pet immune movement sensors have a level of sensitivity that can be adjusted for families with highly active animals.
Other uses of motion sensors
Motion sensors are not just for home security. In industrial fields, they are used on assembly lines to track the number of products and stop dangerous equipment if a person approaches too close. Here are other ways to use motion sensors: To open and close automatic doors, To open and close faucets and automatic toilets, To turn on the lights when a person enters a room, For some parking meters
Best place to install a motion detector?
Although there are several potential locations to install a motion detector, the first choice is the most obvious. Most intruders will check the front door before trying to break a window. The mere fact of installing a motion detector can have a deterrent effect on potential intruders.
Most detectors have a fairly wide range. Walls and ceilings are therefore ideal places to install motion detectors in the home. For example, to prevent your baby from crawling near the water heater, install a motion sensor on the wall or ceiling near the water heater. You will be alerted of movements likely to avoid a possible accident. A professional installer can provide valuable information on positioning and detection range.
Why a motion detector is indispensable for a complete home security system?
An effective motion detector is the backbone of a complete home security system. A motion detector can recognize intruders and trigger alarms. It can be combined with other home security products such as video recorders, broken windows, security cameras, smoke and carbon monoxide alarms and smart locks for a complete security system.
A few great motion detectors for your home security
Flashing cameras detect motion in your home and send HD video and audio alerts directly to your smartphone. Re-record live HD video and audio streams directly to your smartphone from any of your 10 Blink cameras up to 10 Blink cameras per system. Use the infrared night vision of the Blink XT camera or the LED lighting of our classic Blink camera to see what’s happening at night. The water-resistant Blink XT guarantees clear, HD-quality video, regardless of the forecast.
Fully integrated with Amazon Alexa compatible devices, including Amazon Echo, Echo Dot and Amazon Tap. All Blink owners who own these devices can now control their Blink system without lifting a finger, using only the voice. You’ve read correctly With regular use, your Blink cameras will last a very long time with only one set of 2 AA lithium batteries. This incredibly long battery life is made possible by the exclusive chip technology available only in Blink cameras.
The price was very competitive (the price seems to be creeping though). Easy to use and install for the family (children in particular). App works really well. Remote cameras located from the house (50 feet is my farthest and always great – you may need a standard Comcast router / modem at 75 mps). The quality of the picture with the sound is impressive (just like the sound part). Very easy to install. Installed the cameras in less than an hour. Decide where to put them? Take your time before making a decision.
The arm that attaches to the cameras is a little weak. Be careful with that. Seems to be well once installed. If you do not place the cameras in the right place or adjust the sensitivity correctly, you will receive many motion detection notifications. Squirrels and birds love watching this one if you install it in a tree in front of your house.
1byone Wireless Home Security Driveway Alarm
When motion is detected, the passive infrared sensor (PIR) sends a wireless signal to the receiver at a maximum distance of 100 m. By adjusting the receiver, you can choose to be alerted by a high or low chime, a buzzer, or simply by flashing the light. In addition, the receiver can couple up to 50 sensors, which effectively secures a large area. It offers many combinations of sensors and receivers, just choose what best suits your needs.
Do not mount the IRP sensor in direct sunlight (as moving heat sources trigger an IRP) or in a windy location. When installing outdoors, it is best to mount it in a shady and protected area with minimum temperatures. Also avoid mounting on metal door frame or UPVC surfaces that could reduce the range of the transmission.
These are excellent security products. The sensors each take three AAA batteries and are about the size of a deck of cards. The battery life seems good so far. You can install one in your garage – hang it on the wall (screw provided in the box) facing the garage door. You install the second in your backyard, place it in the slats of the fence facing your back door. Both are about 75 feet from your house, with intermediate walls, trees, etc. Now, whenever my garage door moves or moves in the garage, or if the door opens, the sensors ring and you know someone is there. The sensors have about 30 different chimes and have volume controls. They are discreet and look great in the outlets. They work and are a breeze to set up. The system costs me a total of about $ 30 and is very effective. Well worth the money. If you are looking for a reliable and inexpensive motion detection system, it will do the trick. Why pay hundreds when $ 30 is enough? And they look good. And are almost invisible.
Guardline Wireless Driveway Alarm
The Guardline wireless entry alarm alerts you when the outdoor sensor detects the movement of a person, vehicle, or large animal. Super simple to set up. Only takes a few minutes using our quick start guide. Easy do it yourself installation. The set includes a sensor / receiver. Expandable up to 16 sensors and unlimited receivers for complete coverage of your property. Detects movement in 4 different zones and 4 sensors per zone. The sensor operates on (4) AA batteries for up to one year. Low battery indicator included. The receiver can be connected using the supplied AC adapter. Can also work with 4 AAA batteries as a backup in case of power failure. The sensor can detect a movement up to 20 meters. The receiver includes a 12-volt relay to add external alarms, chimes or wired external ringtones.
Easy to install and install. Read the manual first. The transmitter mounts easily on anything. We used a 4 “x4” treated post mounted about 3’6 “from the ground, the message is excessive but looks pretty, does not seem to have a lot of false alarms but will capture everything in the sensor range that has enough movement to trigger the sensor (as it should be) There was an alarm for two weeks and we never saw the reason for the alarm Maybe something blew on the sensor We also have a sprinkler system that sprays water on the sensor and never triggers the alarm, which is a good thing, install the sensor at least 3 or 4 feet above the ground, which will prevent most dogs / cats / squirrels, etc., and do not place it on metal.I would not place it near or near shrubs / tree limbs or similar objects that can move with the wind. the sensor (you must remove the four screws from the sensor). e aisle being reserved for a car, so I reduced the sensitivity level to 23 ‘(game). at 39 ‘from the factory), you can easily adjust the angle of the sensor once installed. Does the sensor’s low battery sensor blink inside the receiver? Easy to add other sensors if needed up to 16 (4 on each zone). Uses the usual batteries. The sensor takes four AA batteries (should last one year); The receiver uses four AAA batteries and / or a wall outlet. The receiver can be connected to installed batteries as a backup battery in the event of a power failure. The receiver has many melodies to select (~ 30) and can be very loud if the volume is set to the maximum. No problem of scope because our sensor is only 150 ‘from the receiver but passes through a few walls. Our sensor is installed in time without any other coating. According to the instructions, it can be mounted anywhere outside and I do not see the need to place the sensor in a protective cover.
Would have liked more color options for the sensor. For example, black, white and camouflage. Worried about losing the small screws when adjusting the sensitivity and / or replacing the batteries in the sensor once installed. It would have been nice if the sensor had been delivered with type screws that did not fall once. Receiver is not the most fun to watch, but we managed to place it in a central location of the house and it’s not so obvious. More than 30 melodies are available, but we were hoping to have more chimes / bells similar to ring style options. Many are song type melodies that we did not like.
