Tape over motion sensor: How to Tape Over Motion Sensor?

Have you ever had a motion sensor go off when you dont want it to? Maybe its because you have forgotten to turn it off or because something has moved that you werent expecting. Either way, it can be annoying. Fortunately, there is an easy fix. All you need is a piece of tape.

Why Tape Over Motion Sensor Works?

Taping over motion sensor works because it blocks the infrared light that the sensor uses to detect movement. Infrared light is invisible to the human eye, but it is what our bodies give off as heat. By blocking the sensors access to this light, you can effectively prevent it from detecting movement.

How to Tape Over Motion Sensor?

Taping over the motion sensor is a simple process.

  • First, find the sensor on your alarm system panel and identify the small black lens in the center. This is the part of the sensor that detects infrared light.
  • Next, take a piece of tape and place it over the lens. Make sure that the entire lens is covered so that no light can get through.
  • You may need to experiment with different types of tape to find one that works best. Some people find that electrical tape or duct tape works well, while others prefer to use clear packing tape.

Once you have found a type of tape that works, all you need to do is replace it every few weeks or as needed to keep your motion sensor from going off unnecessarily.


Can you put tape over motion sensor?

Yes, covering the motion sensor can have a significant impact on its functionality. This is because when you cover a sensor with tape or other materials, it prevents light from reaching it, which blocks the sensors ability to detect movement.

Additionally, in some cases, covering the motion sensor can also disrupt its internal wiring, resulting in erratic or unresponsive behavior. Because of these potential issues, many experts recommend against taping over a sensor and instead directing homeowners to use other methods for reducing their homes energy consumption.

For example, by regularly vacuuming air vents and keeping blinds closed during warmer months, you can help keep your home cool without compromising the performance of your motion sensors.

Ultimately, then, the best way to prevent interference with motion sensors is to take a proactive approach to managing energy usage in your home.

What happens if you cover a motion sensor?


Although motion sensor lights are a great way to deter potential intruders and make your home more secure, they can also be easily defeated by simply blocking the sensor. For most types of motion sensors, this can be achieved by simply covering the device with an object that disrupts its field of vision. For PIR or passive infrared sensors, for example, you can use something as simple as a piece of cardboard to block the sensor from detecting movement. In contrast, microwaves and tomographic sensors cannot be blocked using this method, since they rely on other forms of energy that cannot be jammed or redirected. Ultimately, then, it is important to be aware of the different types of sensor technologies when installing your motion-activated lighting system in order to ensure optimal security for your home.

How do you trick a motion sensor to stay on?


There are many different tips and tricks when it comes to working with motion sensors, and one of the most popular is the so-called quick switch. This involves quickly turning the motion sensor on and off in rapid succession in order to override its normal functionality.

To do a quick switch, simply flip the motion sensor to the ON position, then quickly back to OFF, and then back again to ON. This can be repeated as many times as necessary until you reach your desired outcome - that is, to keep the light turned on without having to keep it constantly moving.

Of course, there are also other methods for overriding a motion sensor that you may want to try, such as simply flipping the switch off partway through an automatic on cycle. However, these methods often require more work and may not always be reliable, while a quick switch remains one of the simplest ways to override a motion sensor. So if you ever need an extra bit of illumination in your home or workspace, give this trick a try!

How do you blind motion sensors?


There are several different methods for blinding motion sensors, including using a simple silicone spray or placing glass in front of the sensor when it is turned off. Both of these methods have distinct advantages and disadvantages.

  • The simplest way to blind a motion detector is by using a thin layer of silicone spray. This greasy substance is practically invisible to the naked eye, and it can easily cover the sensor without anyone noticing. However, there is also a downside to this method: the silicone spray leaves behind a trace that can potentially be detected later on, if someone looks closely enough. Additionally, if you get too much silicone spray on the sensor, it can damage it or interfere with its functioning, preventing it from working properly in the future.
  • Alternatively, you could use glass to temporarily block the motion detector. This strategy has some clear benefits: the sensor is not damaged in any way by this approach, and there is no trace left behind after you remove the glass object from in front of it. However, blocking a motion detector with glass instead of silicone spray also means that someone might notice what you are doing and become suspicious of your motives. This increases the risk that your nefarious activities may be discovered at some point during or after your tampering attempt.

In short, both strategies for blinding motion detectors can be effective under certain circumstances, but each comes with unique risks and trade-offs that should be considered carefully before deciding which approach to take. Ultimately, the decision will depend on your particular situation and what your ultimate goals are for interfering with a motion sensor undetected.


Taping over the motion sensor is a quick and easy way to prevent your motion detector from going off when you dont want it to. All you need is a piece of tape to cover the sensors lens and block the infrared light that it uses to detect movement. This method is temporary and will need to be replaced every few weeks, but it is an effective way to keep your motion detector from Going off unnecessarily.
