What You Should Know Before Buying A Motion Sensor

When buying motion sensors, there are a few things you will need to check first. And they include the following:

The Motion Detection Range

Motion sensors can excellently pick up motions up to a given distance. You can be sure to find motion sensors that can detect movements that are up to 1000 feet away. However, some motion sensors only detect motion up to 200 feet away.

When looking to buy a motion sensor, you want to check the motion detection range. You can then select a given motion sensor, depending on an area you need to place under surveillance.

If you’re looking to monitor a larger room, you want to select a long-range motion sensor. But for a smaller space, a short-range motion sensor will work just fine.

Electrical Power Source

There are plenty of motion sensors on the market today. You can find some that use solar power when the rest use battery power for operation.

There are plenty of electrical power sources for motion sensors. The battery is the best power source. That’s because a battery provides stable electrical energy for 24/7 monitoring of your residential space.

Besides, motion sensors have energy-saving designs, meaning your battery will last at least two years before needing to replace them. Battery power supplies reliable electrical energy to motion sensors.

Therefore, be sure to select motion sensors that use battery power.

Motion Detection Angle

Motion sensors also have angles through which they sweep for signs of movements. Of course, these angles vary from one motion sensor to another.

Some motion sensors only sweep through 110°, but some cover 360°. You want to get a motion sensor with a larger angle since they monitor more extensive areas.

But the price might be an essential factor here because you might pay more with an increase in the motion detection angle. So, always look for a motion sensor with a large motion detection angle.

Motion Detection Technology

Motion sensors use different technologies to detect motions in your living space. It could be a great idea to know about these motion detection technologies. Your motion sensor could be using one of the following motion detection technologies:

Passive infrared (PIR)

These motion sensors detect the body heat from an intruder. By checking the heat signatures, it excellently detects the presence of a person in your smart home.

The motion sensor then communicates with a hub that sends you motion-activated notifications to your smartphone in real-time.

Microwave (MW)

The first thing you might need to know is that these types of motion sensors are quite expensive. And it’s how they work that makes them worth quite a huge amount of money.

So, these motion sensors send out microwave pulses to their surroundings. Then they measure the reflection time. If there is someone in your room, the motion sensors will detect a change in the reflection of the microwave pulses.

It will then send you alerts to your smartphone.

Dual-Technology Motion Detection

Some motion sensors use the two technologies above to detect movements in the monitored areas. They work better to reduce false alarms.

And they’re your go-to units if you’re looking for accuracy and exceptional performance.

Ultrasonic Technology

These motion sensors send out ultrasonic waves and measure the reflection time. That way, they excellently pick up motions within your residential space. They are also an excellent choice for securing your home.


Since motion sensors are one of your smart home devices, you also need to control them from wherever you are! That means you will consider their controls when buying them.

Since you could be anywhere but still need to control your motion sensor, you should consider installing a hub in your smart home. Then connect the motion sensor to this hub to control it remotely via an IFTTT.

Also, look for motion sensors that support voice controls. Such motion sensors work with Alexa or any other voice assistant to let you know if an intruder has breached your home security via voice alerts.

Besides, you could also turn your motion sensor on/off by voice. So, look for motion sensors that also support voice assistants.
