Motion Detecting Sensor

United States authorities estimate that over 7.9 million property crimes took place in the country in 2016. That means that 2,450 crimes happened for every 100,000 individuals.

Scary, right?

Especially since it's not only an issue of having your valuables stolen from you. There's also the more important matter of your emotional and mental well-being. Becoming a victim can traumatize anyone, since this also robs them of their sense of safety and security.

It's for this reason that motion detecting sensors have seen a huge increase in its market value. Experts estimate that come 2022, it'll reach a staggering value of $8.17 billion!

That's because this technology has proven time and time again that it plays a crucial part in home and business security systems. That's why you need them at home.

How do they work and benefit you though?

That's what we'll share with you today, so keep reading!

A Look into Property Criminals' Behaviors

Whether it's a robber, thief, or burglar, they're all criminals who can put your entire household in danger. Infrared motion sensors can help you stop these unlawful individuals before they even set foot in your home.

But to understand the important roles these devices play in your family and property's safety, it pays to know more about the threats themselves. Their way of thinking and how they react to properties with security systems installed.

For starters, a lot of people think these criminals opt to commit their breaking-and-entering activities at night. The truth is, there's a 6% higher chance of such crimes happening around 6 AM to 6 PM.

For the simple reason that it's during these hours most homes sit by themselves, all alone. Think about it. It's when you're away at work and the kids are at school.

There's also the fact that more than 80% of surveyed property criminals say they'd first check for any sign of home alarm before proceeding. 60% of them said they'd look for a new target if there was.

All these should already make you recognize the crime-deterring power of infrared alarm sensors. But here's something to compel you even more:

Not having any kind of security technology increases your home's odds of attracting burglars by 300%!

Now, consider this:

On average, U.S. households spent almost $460 for furniture (and that's only for one piece!) in 2016. Combined with all the other valuable furnishings you have, the worth goes up to thousands.

Sensor-based security devices, on the other hand, can only set you back around $15 to $30 a piece. That's almost nothing compared to what you invest in making your home prettier and more comfortable.

Safety is as critical as these two, so it's time you get around to shopping and installing motion detectors!

What Exactly Do Motion Detecting Sensors Do?

At its core, motion detectors (also known as motion sensors) detect movement that otherwise shouldn't occur. These devices use technologies to monitor movements within their covered range (more on this below).

In a nutshell, when someone or something trips the sensor, the device sends a signal to the control panel of your home security system. From here, you, your chosen monitoring center, or both will receive a potential intruder notification.

If you have sensors installed outside, then you can prevent criminals right from the start. Before they can even enter a door or a window.

Why You Should Invest in Them ASAP

As mentioned above, criminals tend to favor homes that have nobody inside. That means while you're hard at work, or your kids are doing their best in school.

Motion sensors help protect your family and valuables during these times you can't. As such, it's best that you include these devices as part of your more comprehensive home security system.

After all, they're the first layer of defense, since they can keep criminals outside - where they belong.

The Primary Goal of Motion Detectors

To sense unauthorized "guests" and alert you right away, so you can respond as soon as possible!

A good way to maximize your motion sensors is to set them up outside, such as within your gate, driveway, or by the front door/windows. When potential criminals (or wild animals) creep up to your front door, they'll trip the sensor.

This then gives you time to notify the proper authorities.

Protecting your home and valuables isn't the only role of these devices though. They can also help you up your home security and safety ante through the following:

  • Inform you when your kids or pets enter a safety hazard area in/around your property
  • Monitor the comings and goings (including your teenage kids!) of people at home
  • Tell you that your expected visitors have arrived
  • Better control over your automatic doors (sliding doors or electronic gates)

Furthermore, you can set up some sensors with your computer, laptop, tablet, or smartphone. Doing so lets you control them wherever you are! That's even more safety and convenience for you.

Since you can access your security system through these devices, you can check if someone forgot to turn off the lights before leaving home. Depending on the security technology you use, you may turn them off remotely. This then helps you bring your energy costs down!

The Simple Yet Effective Technology Behind These Sensors

So, how do motion sensors work? That depends on the type of "sensing" technology they use. There are several, including the following:

Passive Infrared Sensors

Some motion detecting sensors rely on Passive Infrared (PIR), which detects infrared energy (AKA body heat). These sensors are the most common in home security systems.

Soon after you arm your PIR motion detectors, they'll generate heat and create something like a protective net. They then detect movements within this net. If they sense movement, they'll send a notification right away.

Another way to trip these sensors is when someone or something blocks areas of this net or grid. When this happens, the infrared energy level fluctuates. This change trips the sensors, and you or your security company receives an alert.

MicroWave (MW) Sensors

These sensors offer motion sensing technology for a larger area. They rely on microwave pulses to detect movements through an object's reflection.

Seeing as they cover more ground, prepare yourself to pay more for these sensors. Also note that electrical pulses tend to mess and interfere with them.

PIR and MW Sensors

Also known as "Dual Technology" motion detectors, these sensors use both infrared and microwave pulses to determine movement when there shouldn't be.

The primary goal of these security devices is to reduce false alarms. For something to trigger the sensor, the "object" should trigger the sensors of both technologies (the PIR and MW).

Vibration Sensors

As the term suggests, these sensors react to vibrations. As you know, any movement (and sound) produce vibrations, so anything that generate such will trigger the device. They're easy to install, but they also tend to cause more false alarms.

Critical Features to Consider

All the above-discussed motion detectors tell you how motion sensors work. But as important is knowing which features make them the most ideal for your entire household.

Remember, these security devices have varying capabilities, so make sure you base your decision on the following:

Ease of Set Up and Installation

Some sensors may be too complex for an average homeowner, although these can provide greater security. Some are easy to mount and install on your own, without having the need to drill holes on your walls.

If you plan to have your security system installed by a professional, then by all means, go for the whole shebang. But be sure you can still operate it on your own.

Range

This refers to the field of vision or coverage area. Make sure you don't put too much distance between the sensor itself and its receiver. Basic motion detectors work well with shorter driveways or smaller spaces for monitoring.

Pet Immunity

A common issue when it comes to motion sensors is their tendency for false alarms. In many cases, pets are the ones tripping sensors.

This said, consider going for pet-immune sensors so that you won't have to worry every time they enter the device's coverage area.

Invest in the Right Motion Sensors Now

A burglary occurs every 20 seconds in the United States. A robbery in every 4.2 minutes.

That means hundreds of possibilities every day to become a victim when you leave your home without any type of security device.

So, before you become part of the concerning statistics, equip your home with a solid security system, including the best motion detecting sensors.
