Best motion sensors 2020: Buying Guide

Safety is the key ingredient to a happy home and a viable business. The lights emitted from the movement sensors at the appropriate time are often a good deterrent to trespassers or intruders. Let’s find out what are the best motion sensors to buy.

It is well known that criminals attack more easily isolated private buildings or commercial, that have few sources of light, so as not to be caught in the act. In order to strengthen security and to improve the lifestyle of the inhabitants and workers, they are available on the market several models of motion sensors. We see below what are the best and what parameters to consider for an appropriate choice for the home or business.

Example of a motion sensor from internal Philips.

As can be guessed from its name, the motion sensors are products designed to ignite when warn any movements around a specific area, whose amplitude is variable depending on the individual model.

Among the main features that this great – and cheap – product performs gather those concerning the security of a property: the motion sensors, in fact, they can alert residents about the presence of intruders, which at the same time they are frightened by ‘ ignition of lights activated by the sensor.

In addition to being an effective support in helping to prevent break-ins by malicious, the motion sensor provides numerous other advantages. For example, these devices have considerable potential to make the best for those who want to contain their energy consumption and have a special focus on environmental sustainability. Many of the best models on the market in fact allow you to reduce energy costs, illuminating dark areas of the house only when necessary.

How do they work

Operation of a motion sensor.

The motion sensors are in the first instance a safety system, designed to detect the presence of unwanted people. They are based on different technologies, often combined within a single model, designed to detect movement within the area in which the sensor is installed.

Once the sensor has made a detection, the light turns on and illuminates the surrounding area and anyone who passes nearby. In addition to regulatory requirements, these objects are important to answer the needs of an increasingly intelligent home automation and designed for the modern lifestyle.

How to choose a motion sensor

After I provided a general overview of these devices, it’s time to find out how to choose the best motion sensor for your needs. Read on to find out all the things to know before purchasing.


There are a number of sensors used to detect movement: among the most common ones are passive infrared, ultrasonic, microwave and vibration.

As evidence of the great strides being made to make these increasingly precise objects, were born of dual technology motion sensors, which combine two different to be able to reduce false alarms. Here, then, that in the case of these particular sensors, both types of detection must be activated to result in ignition of the lights or in any action.

For example, a vibration sensor may be activated by branches that move due to the wind, but with the dual technology, the light would not be activated because the infrared sensor would not disclose the heat coming from the branches. In addition to these types, for sure the most common, mention should be made of contact motion sensors, very cheap, and the reflections sensors. The latter, are employed exclusively in the supervision, LEDs emit a light beam which, if crossed, activates the sensor.

Response time

One of the aspects that most differentiates the various types of motion sensors is found in the reaction time, ie the seconds required for the sensor to be able to turn on the light starting from the moment in which it is detected for the first time the movement. Similarly, the reaction time can also be measured in the shutdown.

More than one sensor is sensitive, the lower the reaction time: this aspect is very important especially in the passage of environments, such as stairs or the corridors, where there is no time to wait and the light should light up as soon as possible.

Distance and bearing angle

The devices on the market also vary in a very sensitive with regard to the distance and the angle of the motion detection.

These two elements, in particular the scope of the survey, are useful parameters that guide in identifying the most suitable models. For example, those who have a radius smaller than can be applied inside, while in areas where it is difficult to follow the different movements is important to choose a sensor at 180 ° or even 360 °, that allow to illuminate the area at best.

Autonomy and battery

For ease of installation, battery power would seem the best option, especially for the outside: using rechargeable batteries is not necessary any wiring. The batteries will last about a year if you consider an average of ten activations per day, but the sensor is located in a busy area, the batteries will not last long.

The lighting with motion sensor wired is the most common and should not scare you: most of the systems includes detailed instructions and tutorials to which to refer. For those who want to reduce consumption and choose the most sustainable option, it may be worth investing in motion sensors to solar power, easy to install and use. They are perfect to ensure the use even during a power failure, as long as there is enough stored energy.

However, there are some downsides to this type of sensor. The solar energy lamps require about 6-8 hours of light per day to function properly and there are few areas where such a large amount of light is available. In addition, if the mounting position does not receive direct sunlight, the solar energy sensor may not be the best solution.

How to place the motion sensors

Even in this case the internal or external positioning will be an important index to be taken into consideration to choose the best place. For internal motion sensors it is important to choose areas of transition and ensure that there are no obstructions that may interfere with the affected area by the sensor.

It is important in this case, try not to put sensors near windows, because any curtains that move could activate the sensor, and if there are pets, it is best to choose a sensor that does not detect their passes.

In the case instead of an external motion sensor, it should be positioned in difficult to access areas to prevent damage. It is crucial to consider the range of the sensor: placing too high, in fact, will not be able to effectively capture. Finally, attention should be paid to exposure to light or heat sources that could damage it.

Conclusions and final considerations

Within this study we examined all the parameters that can play an important role in the choice of a specific model of motion sensor. Some of these, such as autonomy, the angle of detection, the reaction time, are important, while others, such as the internal or external positioning, are really fundamental.

The motion sensor to choose for your residence or business will depend ultimately on the individual lifestyle needs and budget. Regardless of the model, the installation of one of these precious objects should not take too long and fail to deter potential thieves, while at the same time will make life easier for residents.

A motion sensor is a great product, on which it is worth investing to protect the environment, people and their valuables.
