Some Motion Sensor Detectors Are Not Best Fit For Home


Motion detector sensors are installed in homes, offices, schools, or any other workplace for security purposes because they sense the entry of any unwanted person in your home or office and send signals to your control panel attached to it to notify you about this suspicious entry. You might be thinking that you have heard that motion detector sensors are not suitable to be installed in homes.

Yes, you have heard it right, but that’s not true for all types of sensors, but some particular kinds like the wireless ones. So, what can be the disadvantages of using them in your house? Hold on, we will discuss it in this article in detail. The sensors detecting only within the radio range, those working on Wi-Fi only, and those using batteries are not best for your home.

How Does Motion Detector Sensor Work?

So, the working of motion detector sensor is based on the type of sensor because mainly there are two types of these detectors:

  • Active ultrasonic detector
  • Passive infrared detector
  • Active ultrasonic detector: This type of detector emits ultrasonic waves that reflect the point of emission, and if there is any object or a person that disturbs the path of this ultrasonic wave, it will detect it, and the alarm will alert the owners about it with an alarm ring or by turning a light on.
  • Passive Infrared detector: Mostly, the detectors used in our homes are based on passive infrared detection; infrared rays are those which humans and animals generally release out of their bodies as heat. If there is an increased infrared radiation emission, the PIR sensors detect and notify the homeowners by ringing the alarm. Still, you have to ignore small changes like there can be some temperature fluctuation, or it can be your pet, cat, or dog passing by.

The lenses on these motion detector sensors are broken into segments. So the question is, why would the lens be broken into segments? This feature allows the users to focus only on particular areas to detect suspicious movements and ignore the other areas.

Also, this is helpful because it will alert and notify you if there is any home invader, but not when your pet cat passes by. So it is more user-friendly with these segmented lenses.

Purpose of Motion Detector Sensors:

So you might be wondering why you need a motion detector sensor in your home. How will it benefit you? So here are some major uses of motion detector sensors:

  • Motion detection: These motion detector sensors detect unwanted persons, like thieves entering your house or workplace.
  • Security Alert: Motion detector sensors alert you when someone enters the restricted areas of your home like the basement, garage, etc.
  • Energy-Saving: Using them saves energy because they only turn on lights where needed.

To conclude, it would be better to say that these sensors are installed and placed in your home or any other place for security purposes so that if anyone tries to cross the restricted area, you will be informed so that you may take action against it.

Disadvantages of Using Motion Detector Sensors:

Here are some reasons why motion detector sensors are not the best fit for homes:

  • Usage of batteries.
  • Detecting the motion within the radio range only
  • Wireless sensors that work on Wi-Fi.

Usage of Batteries:

One of the main drawbacks of the motion sensors is that the alarms use batteries to work, so for their proper working, you need to check regularly if the batteries are working or not or if they are expired because, without batteries, they will not be able to detect any motion. There is no use in installing it like that. So to make it function properly, you need to change the batteries whenever they stop working.

Moreover, changing batteries is not the only issue here because when you need to change them regularly, they will cost you money, of course. Not all people can afford to buy new batteries for their motion detector sensors every other day. So it is suggested that these motion detector sensors are more suitable for offices and schools than homes.

Detecting Within The Radio Range:

Most wireless motion detector sensors only detect the objects that are within the radio range, which means if you have a large office or house, there is a high chance of unwanted entries that will not be detected by the wireless motion sensor that you have installed because if the object is not within the radio range, how can it be detected?

Not only this, but there is another main issue with these wireless motion detector sensors because they are usually installed at the main entrances of your house, office, school, or wherever it is being used. So if a detector is only installed at the main entrance, what if an unwanted person enters your house from the back door or any other entrance? The detector will not sense its motion, of course.

Wireless Sensors Using Wi-Fi:

Some wireless motion detector sensor uses Wi-Fi to function properly and serve their purpose. We all know that hackers can easily hack the Wi-Fi password, be it your Wi-Fi or the one connected to your home’s wireless motion sensors. So if you are installing a wireless detector in your home, office, or any other place of use, keep in mind to keep a strong password so that it cannot be hacked easily.

Also, the signals sent by WiFi-based sensors get lost easily, so they are not as reliable as wired ones. So that’s why avoiding wireless sensors in your homes is suggested, especially those that work on Wi-Fi.

Once a hacker hacks your Wi-Fi password, your motion detector sensor will be useless. Anyone will be able to enter your house or office. So it is always advised to be careful and wise while choosing the passwords for your detection sensors.

FAQs:

How many motion sensors should a house have?

The number of motion detector sensors installed in a house depends on its size or the layout of the basement of the house. If it is of normal size, having only one motion sensor installed, there is enough to detect suspicious motions. Still, if it is large, you can have another detector in the corner so that you will be able to detect from forty meters away.

Can we fit the motion detector to any light?

If you want to fit a motion sensor detector to any light, you should get a remote-style motion sensor because it can fit all the lights of your house, even decorative ones. It will be more helpful to install it this way because it will be a secret, and nobody can notice that you have a motion detector sensor installed in your home.

Which type of motion sensor is the best?

Passive infrared detectors are the best type of sensors you can install in your home that will help you detect and investigate the entries of unwanted persons in your home.

Do all motion sensors work with LED lights?

If your sensor has an electromechanical relay, it will work fine with LED lights. Still, if the motion sensor comes with an electronic switch, the sensor may not work with the low voltage LED lights as they need a minimum load to power the motion detector sensor on the circuit.

Can you tell the difference between motion sensors and motion detectors?

Motion sensors and motion detectors are two names used for the same thing. A motion sensor is a detecting system that detects the movement of a person who should not be there in your home, and if there is someone like that is detected, it will notify you by switching the light on or by ringing the alarm. Hence, you can say that it is a security system installed in homes or offices, etc.

Conclusion:

So, are you planning to install a motion detector sensor in your home? And you are worried because you don’t know much about it and don’t know what type of detector is suitable for your home?

There is nothing to worry about because we have mentioned all the necessary details about motion detector sensors and their type. After all, that’s all you need to know before buying one for your house.

But, here is a friendly and important reminder that you don’t prefer buying the sensors that work on Wi-Fi and batteries and the ones that only detect movements within radio ranges as they are not that reliable for homes. CWP
