How Do You Blind Motion Sensors?

Motion sensors are systems that operate to detect any movement in the monitored area. They are mainly installed at homes, offices, and businesses. Motion sensors are extremely useful in warding off intruders and preventing robberies. Different types of motion detectors can be used to ensure the safety of your property, but most of them follow the same principle.

We all know the importance of motion sensors in providing foolproof security, and there is no doubt motion sensors are one of the best tools you have for this purpose.

However, on several occasions, you have to blind motion sensors to prevent false alarms as long as you are doing some work that may otherwise activate the motion sensors.

Homeowners and other users who have been using the motion sensors for their security are usually unaware of how do you blind motion sensors. As a result, they end up damaging the motion sensor system, which also costs you money aside from jeopardizing the security.

To make sure that you know how do you blind motion sensors, you need to understand its working mechanism, and then you can implement how you blind motion sensors.

For this reason, here in this article, you will get all the related information so that next time you need to blind motion sensors, you know how to do it without damaging them in any way.

How Do Motion Sensors Work?

Motion detectors or sensors work based on infrared rays, and they have a component that is sensitive to infrared ways and detects them. Everything emits rays, but the human body emits a great deal of heat; infrared radiations. So when the motion detectors detect the infrared radiations, the alarms go off, and any connected lights will turn on. It makes sure that no one is at your premises.

Other than that, you will also find motion sensors working on microwave pulses. To enhance its functionality, you will also find motion sensors working with dual technology, combining infrared and microwave sensors.

How to Blind Motion Sensors?

Bypassing or blinding motion sensors can be difficult, but it can be done when you understand how they work. For example, some motion sensors emit light rays and detect when they are reflected, and infrared radiations trigger some.

To blind any motion detectors, you can follow the below-mentioned steps:

Don’t Rush

The thing you need to be aware of to bypass a motion sensor is not to rush. Instead, take little steps and move from one area to another in longer intervals. You can try taking some slow steps and then resting at a place for a while; it can convince the motion detector that there is no movement.

Always keep track of what areas the motion detector is monitoring. If you find a blind spot, remember to make use of it.

Remember that when you try to bypass one motion sensor by moving slowly, you might be in the way of another motion detector across the room. Some motion detectors have long-range, while some motion detectors have a shorter range. Make sure to move slowly and inspect which other areas have motion sensors that you might trigger.

Try to Make No Sound

Because of sound, the light waves emitted by the motion sensors bend. Due to this, the alarm connected to the motion sensor is triggered. To avoid this, you should stay as quiet as possible. Do not make a noise in any way. Try to be as silent as possible. To do this, you might need to explore the area monitored by the motion sensor and avoid anything that can make a noise.

You can take off your shoes and put your mobile phone on silent. To bypass the security system in this way, you should know that the motion sensor detects even the slightest noise, so notice the ground you are walking on and make sure that you make no sound.

Move Along the Walls

Most motion sensors are placed on walls and have blind spots which they cannot monitor. Most of them being the wall that they are installed on. To take advantage of the blind spots, move slowly along the walls and remember not to make any sound as you are closer to the motion detector, and it can easily detect even the faintest of sound there.

Moving along the walls helps you bypass the security system when there is almost no monitoring in that area. To ensure if there are blind spots on the wall or not, you need to move slowly. Get yourself as close to the wall as possible so that the motion sensor may not detect you.

Stay Low

Most of the motion detectors have the calibration to make them pet-friendly. This means that they do not get triggered by dogs, cats, and other pets. Those motion detectors do not monitor the vicinity below the average height of pets, and you can use that. Try to be on your knees and move slowly at the size that most pets would walk on.

As these motion detectors are calibrated to make pets move freely without triggering any alarm, you would not be detected by the motion detectors if you move at the same height. There is an advantage in this as you can even freely move behind any tables or other furniture covering most of your body. Furthermore, you can move behind the furniture at a slow speed so that you may bypass the security system.


Bypassing a motion sensor can be a difficult task, but you can certainly do it when you have a proper understanding of all the areas that are monitored by the motion sensors.

Several motion sensors have limited sight, which increases the chances of being blinded by anyone moving slowly and out of their range. By reading this article, you will know all the related information on how do you blind motion sensors without compromising their operational capability.
