How do motion sensing lights work is a very important question to ask if you are looking to have one installed in your home or office. Motion sensing light is just more than shining bright lights, they are burglary-proof and give owners a sense of security in their homes.

In this guide, we will tell you all that you need to know about motion-sensing lights. We will also discuss the best motion-sensing light features and where best to install them if you eventually decide to get one.

This article will also look at the different types of motion sensing lights to help you decide what’s best for you.

Meanwhile, below is our table of contents.

What is A Motion Sensor Light?

So how do the motion and light sensors operate? A motion sensor light is, in essence, an electrical device that activates when it senses motion. Basically, the sensors that turn on in reaction to human movement are connected to the light bulb.

Anywhere there is a light source, such as walls, ceilings, driveways, front porches, or the exterior of a house, motion detector lights can be installed. Often referred to as occupancy sensors, these devices are becoming a more and more well-liked option for cutting down on home energy consumption.

What Are the Different Types of Motion Sensors, and What Can They Do?

Passive Infrared Sensor

The passive infrared sensor is widely employed as a motion sensor, particularly in residential security systems. Its function involves detecting alterations in room temperatures through the identification of body heat, effectively signaling the presence of an intruder. This technology is implemented in our motion sensors.

Microwave (MW)

Microwave sensors emit imperceptible waves that capture reflections from moving objects. While these sensors can surveil larger areas compared to infrared sensors, they are more susceptible to interference from objects.

Dual Technology Motion Sensors

Certain motion sensors integrate both the aforementioned methods, offering a combined approach to motion detection.

These represent the three primary categories of motion sensors, each presenting distinct capabilities. The integration of these sensors with other smart products opens up exciting possibilities. (It’s worth noting that our motion sensors utilize passive infrared technology!)

What Can I Pair With Motion Sensors?

The most obvious expansion is using your wireless motion sensor in conjunction with smart plugs, light switches, or bulbs. Together, these goods may make it such that when the sensor senses movement, your lights will come on automatically.

This is useful not just for setting up your own home security system but also for those regular occasions when you enter a dark house with full hands. No more stumbling over abandoned shoes in your foyer!

Combining one of our motion sensors with a smart camera is an additional brilliant idea. When the motion sensor trips, you can investigate the reason for the lights turning on by using a smart home app (such as the CYNC Smart Home App, which is powered by Savant).

Where Should Motion Sensors Be Placed?

Consider the location of the action when choosing where to install your motion sensor. Main points of access should be your primary concern, particularly if you’re employing them for security reasons. Front hallways, back halls, and foyers are excellent places to start.

You’ll probably be shocked at how well this technology works with other interior design elements. If you have good taste, consider arranging them in small vignettes—groups of well-chosen objects that complement one another. They look good mixed in with books, vases, and other housewares.

Additionally, there are several locations where you shouldn’t put your motion sensor. You should avoid placing your motion sensor next to a radiator because it can detect body heat and generate false alarms.

And windows can provide glare and reflections that skew results and make the tech less effective.

How Do You Install a Motion Sensor?

Installing a motion sensor is quite easy, particularly if you choose a standalone option. Here, we’ve included instructions for mounting sensors and positioning them in relation to other objects. Of course, you can always hire a pro to mount your motion sensor if you’re not interested in doing it yourself.

To Mount Your Motion Sensor: DIY

Recommended Tools:

Phillips Screwdriver, Drill w/ 7/32 bit, Tape Measure, Screw Mount


Step 1: Before installing, remove the plastic battery tab.

Step 2: Identify where you want to mount your motion sensor (recommend placing it between 66-78” from the floor).

3 Step: Mark the location for the hole to be drilled.

Step 4: Using a 7/32” bit, drill a hole in the wall for the mounting screw, and insert the anchor.

Step 5: Remove the magnetic mount from the bracket, screw the bracket into the wall until flush, then replace the magnetic mount in the bracket.

6th Step: Mount the motion sensor at the desired angle.

To Have a Freestanding Motion Sensor

Step 1: The magnetic mount that comes with the motion sensor allows it to be positioned either vertically or horizontally.

Step 2: Decide on the location of your motion sensor. Your sensor should be placed on any level shelf or surface.

Step 3: Set the motion sensor in place and turn it to the desired degree.

Benefits Of Motion Sensor Lights

1. Automation

Motion sensor lights are perfect if you enjoy utilizing the newest, most advanced security technologies and high-tech gear. Installing these motion detectors means that the system will take care of turning on the lights automatically, saving you from ever having to do so. Not to mention, it gives your house a contemporary feel and is quite easy to use.

2. Conserves Energy

The energy and cost savings associated with purchasing motion sensor lights are further advantages. As soon as you leave the room, the motion detectors turn off automatically to conserve energy. You won’t have to stress about forgetting to turn on the lights when you dash out of the house for work thanks to this technology.

3. Prevents Trespassers And Burglars

Motion sensor technology is widely used in the security business, as we have indicated, for alarms and other applications. Using motion sensor lights outside to flood the front or backyard with light can aid in the detection of intruders and criminals. Outdoor motion sensor lights will deter burglars from prowling around the property after dark if they unexpectedly switch on.

Features To Look For When Buying Motion Sensor Lights

Now, let’s take a look at the different features you should look for when purchasing a motion detector light:

How Do Burglar Alarms work

Burglar alarms, also known as security alarms or intrusion detection systems, are designed to detect unauthorized entry or intrusion into a building or area. The primary goal of these systems is to alert the property owner or a monitoring service about potential security breaches. Here’s a general overview of how burglar alarms work:

Detection Sensors:

  • Motion Sensors: These sensors detect movement within a defined area. Passive Infrared (PIR) sensors are common, reacting to changes in infrared radiation caused by movement.
  • Door and Window Sensors: Placed on doors and windows, these sensors trigger an alarm when the entry point is opened or breached.
  • Glass Break Sensors: These sensors respond to the sound frequency produced when glass is broken.

Control Panel:

  • The control panel is the central processing unit of the burglar alarm system. It receives signals from the detection sensors and manages the overall operation of the system.
  • In more advanced systems, the control panel may have additional features such as a keypad for arming and disarming, a display for system status, and connectivity options for remote monitoring.

Keypad or Remote Control:

  • The keypad allows users to arm and disarm the system using a unique code. Some systems also come with remote controls or mobile apps for added convenience.

Siren or Alarm Sound:

  • When a sensor detects a potential intrusion, it sends a signal to the control panel. If the system is armed, the control panel activates an audible alarm, typically a loud siren, to alert occupants and deter intruders.

Monitoring Services:

  • Many burglar alarm systems are connected to monitoring services. In the event of an alarm activation, the monitoring service is notified automatically. The service can then verify the alarm and, if necessary, contact law enforcement or the property owner.

Communication Methods:

  • Wired Systems: Traditional burglar alarm systems are hardwired, with sensors connected to the control panel through physical wiring.
  • Wireless Systems: Modern systems often use wireless communication between sensors and the control panel, providing more flexibility in installation.

Integration with Other Systems:

  • Some burglar alarm systems integrate with other security features such as surveillance cameras, access control systems, or home automation systems. This integration allows for a more comprehensive security setup.

Arming Modes:

  • Burglar alarms typically have different arming modes, such as “Away” mode for when the property is vacant and “Stay” mode for when occupants are inside but want perimeter protection.

Understanding how burglar alarms work is crucial for effectively securing a property. Regular maintenance and testing ensure that the system remains reliable and provides the intended protection against unauthorized access.
