The motion sensor detects movements at an angle of 120 degrees and at a distance of up to three metres. Customers are convinced of the price-performance ratio and the possibility of using the LED as a night light.
Guide: Questions you should consider before buying a motion detector for indoors
How does an indoor motion detector work?
The word “motion detector” is a generic term for several types of devices, each of which functions differently.
What they have in common, however, is that they can detect movements of people and also animals and then emit a signal.
The most commonly used indoor motion detector is the passive infrared detector (PIR detector). This type of indoor motion detector receives infrared radiation (heat radiation).
What does an indoor motion detector cost?
Depending on the quality and functionality you choose, the price of an indoor motion sensor can vary greatly.
The average price of a higher quality indoor motion sensor is between 40 and 200 Euros. But if you want to find out whether an indoor motion detector is right for you, you can buy a simple motion detector with a socket connection for as little as 10 euros.
Where can I buy an indoor motion detector?
You can purchase an indoor motion detector online or locally. For the latter, you can ask at a DIY store or electronics store near you. According to research, you can easily buy an indoor motion detector here:
Why is a motion detector useful for indoor use?
Motion detectors for indoors are helpful devices. For example, if you have both hands full and can’t turn on the lights, an indoor motion detector can do the job for you. In your home, you can easily automate certain procedures with an indoor motion detector. For example, if you have a dark room where you always have to turn on the light, an indoor motion detector can always turn the light on for you.
However, an indoor motion detector is also a useful addition to burglary protection. You can either let it switch on the light to deter burglars.
What alternatives are there to an indoor motion detector?
If you decide to use the indoor motion detector as an automatic light switch, you will not find a real alternative. However, if you are considering using an indoor motion detector as an alarm system, you may be interested in a real alarm system as an alternative.
Decision: What types of indoor motion detectors are there and which one is right for you?
If you decide to get an indoor motion detector, you are forced to decide which type of indoor motion detector is best for you. Basically you can distinguish between three types:
- Passive infrared detectors (PIR detectors)
- Radar motion detector
- Ultrasonic motion detector
Each of these indoor motion detectors has its advantages and disadvantages. Below you will find more detailed information on the individual types of motion detector.
What distinguishes a passive infrared detector for indoor use and what are its advantages and disadvantages?
A passive infrared detector (PIR detector) does not send its own signals, but only receives reflected infrared radiation (heat radiation). For this reason it can be called a “passive” motion detector. The lens in the PIR detector focuses the received radiation. The detection area for which the motion detector is responsible is shown as a grid.
Detection range very accurate
various designs available
can be very easily influenced
even radiators can lead to false triggering
This type of indoor motion detector is the most commonly used. However, it also has a few typical sources of error. If a person moves directly towards the motion detector, the PIR detector will have problems detecting the movement. For this reason, it may trigger either very late or not at all, which can be a big disadvantage in case of a break-in.
What distinguishes a radar motion detector for indoor use and what are its advantages and disadvantages?
Besides the passive infrared detector, a radar motion detector is the most commonly used indoor motion detector. Unlike the PIR detector, the radar motion detector is not passive. The device emits electromagnetic waves. When these waves hit an object, they are reflected back, which is detected by the radar motion detector. Over the time it takes for the waves to return to the motion detector, the radar motion detector measures the distances to the objects. If this time changes, for example becomes shorter or longer, the motion detector detects this as motion and gives a signal.
very precise recording
also perceives movement through materials such as wood or plastic
Sensitivity is adjustable
detects even the smallest movements, e.g. of cats
if the path of the electromagnetic waves is disturbed, errors may occur
Due to the applied technology, the radar motion detector is much more sensitive than the HIR motion detector. This can be a big advantage on the one hand, but on the other hand you have a problem if you have pets-
What distinguishes an ultrasonic motion detector for indoor use and what are its advantages and disadvantages?
An ultrasonic motion detector, as the name suggests, sends and receives ultrasonic signals, which makes it an active motion detector, unlike the PIR detector. The indoor motion detector reacts when the ultrasonic waves it emits and then reflects change. This is the case, for example, when an object moves. There are a few things you need to pay attention to when installing. Because the ultrasonic waves are transmitted through the air, the ultrasonic motion detector must not be located behind curtains, over radiators, in the vicinity of ventilation slots or near switching sources, for example.
more flexible monitoring areas
is adversely affected by many factors
very prone to error
reliable detection range very small
In addition, you also have to put yourself in the position of the burglar to some extent during the installation. The closer you get to the motion detector, the greater the change in the ultrasonic waves and the more the motion detector perceives movement. This means that if the burglar moves further away from the motion sensor, it is possible that the motion sensor will not trigger.
Purchase criteria: You can use these factors to compare and evaluate indoor motion detectors
Below you will find a list of aspects that will help you decide between the many possible motion detectors for indoor use. The criteria, with the help of which you can determine
- Type of drive
- Possible applications
In the following paragraphs we will explain what is important for the individual criteria.
You can install an indoor motion detector in two ways: Flush-mounted or surface-mounted. For indoors, it is recommended that you install it under the plaster, as this makes the motion detector much more inconspicuous.
The way you can operate an indoor motion sensor depends on the brand of your choice. Basically, an indoor motion detector works by itself after installation and alignment. Some indoor motion detectors can be adjusted with a switch or remote control, while others can only be adjusted on the device itself.
Type of drive
An indoor motion detector can be used in many ways. Probably the most common use of a motion detector is in combination with a lamp.
You can also use an indoor motion detector to monitor your home and connect it to an alarm system. Instead of turning on the lights, the motion detector gives a security warning. Another possibility is to use the motion detector in combination with a surveillance camera.
Trivia: Worth knowing facts about indoor motion detectors
How can I set my motion detector for indoor use?
There is no single guide describing how to set your motion detector for indoor use. You have to refer to the manual of your own motion detector.
If you have lost your manual, you can also try out the settings until you reach your desired destination. However, if you prefer to read a manual, some manufacturers’ manuals can also be found on the Internet.
What can I do if my motion detector for inside is constantly on or does not go off at all?
There are several reasons why your motion detector is constantly going on inside. But you have to distinguish between a new and an existing installation. In the case of a new installation, it is possible that you have simply connected the motion sensor incorrectly. In the case of an existing installation, it can look quite different, because the possible causes can be many and varied. In this case it is best to consult a specialist, because as a layman it is difficult to find the cause.
