Blocking Infrared On Surveillance Cameras: A Step-By-Step Guide

Surveillance cameras are a common security measure, but they can also be used to invade privacy. If you want to block an infrared (IR) surveillance camera, there are several methods you can use. Firstly, identify the location of the camera and shine a powerful LED light or flashlight directly into the lens. This will create a lens flare, making it difficult for the camera to capture your face. Alternatively, you can use an infrared laser pointer, which is more subtle but requires precision as the camera will capture your face if the laser slips away from the lens. Another option is to attach infrared LEDs to your clothing, such as a hat or headband, to overwhelm the camera with light and obscure your face. However, be cautious as using camera-blocking methods may be illegal in some jurisdictions.

Use a Mylar foil thermal blanket

Mylar foil thermal blankets are made of heat-reflective, thin plastic sheeting and are very light and bulky. They are perfect for situations where weight or space is limited. They are commonly used for heat management on the external surfaces of spacecraft and people. Mylar foil thermal blankets are designed to reduce the energy loss in a person's body that would ordinarily occur due to thermal radiation, convection, or water evaporation.

The blanket makes the areas of your body covered by it virtually invisible to a thermal imaging camera because it prevents your body heat from escaping. If you're worried about overhead thermal imaging cameras, you can buy a tarp made of the same material and make a tent out of it.

However, it's important to note that your body heat will accumulate inside the blanket or fly away, which will then be visible to IR images. While a Mylar foil thermal blanket can be effective in blocking IR, it is not a perfect solution and should be used in conjunction with other techniques for optimal results.

Shine a powerful LED into the camera lens

One way to block infrared cameras is to shine a powerful LED directly into the camera lens. This method is best performed at night or in enclosed spaces as it only works well in the dark. The brighter the flashlight, the better.

To blind the camera, you must figure out its exact location and shine the light directly into the lens. This will create a lens flare, making it almost impossible to identify your face. However, this method is not subtle, and the sudden flash of light will alert any vigilant guard to your presence.

It is important to note that you must be quick and precise when using this technique. If the light beam moves away from the camera lens, your face will be revealed. Additionally, ensure that the bright light does not shine onto your face.

This method requires a steady hand and precision, but it can be an effective way to obscure your identity from surveillance cameras.

Attach infrared LEDs to your clothing

One way to block IR on surveillance cameras is to attach infrared LEDs to your clothing. This method can be used to obscure your face from cameras, but it is not a perfect solution and requires precision to be effective.

To attach infrared LEDs to your clothing, you can try a quick fix by supergluing a string of bright infrared LEDs to a hat or headband. For a more involved approach, you can craft an LED "mask" that heavily obscures your face. It is important to ensure that the LEDs are bright enough to blot out your face from the camera's view without being so bright that they cause discomfort or distraction.

When using this method, it is crucial to position the LEDs carefully so that the light is directed towards the camera lens. The effectiveness of this technique also depends on the type of camera you are trying to block. Some cameras have IR filters that can reduce the impact of infrared LEDs. Additionally, this method may be more effective in low-light conditions or at night when cameras are in night mode and more sensitive to infrared light.

While attaching infrared LEDs to your clothing can be a creative solution, it is important to note that it may not always be legal. In some jurisdictions, using camera-blocking technology like LEDs or lasers can result in criminal charges or civil lawsuits. Therefore, it is essential to understand the laws in your area before attempting to block surveillance cameras in this manner.

Point an infrared laser into the camera lens

Pointing an infrared laser directly into the lens of a surveillance camera is a subtle way to block the camera's view. This method can be used during the day or at night, but it requires precision. If the laser slips away from the lens, even for a moment, the camera will capture your face. It is also challenging to gauge the effectiveness of this method, as you cannot tell if the laser is aimed correctly from your end.

It is important to note that disabling security cameras with a laser is illegal in most jurisdictions. Additionally, there is a risk of eye damage if the laser is too powerful. When using this method, it is crucial to act quickly and efficiently to avoid detection.

• Use a standard laser pointer or a more powerful laser for a stronger blinding effect.
• Be precise and quick to avoid being detected by the camera.
• Consider wearing dark glasses to protect your eyes, but do not rely solely on them.
• Coordinate with friends if you need to block multiple cameras simultaneously.
• Be aware that anything blocking the path between the laser and the camera will instantly un-blind the camera.

While this method can be effective, it is important to use it responsibly and within legal boundaries.

Use a UV protection umbrella

Surveillance cameras are everywhere, and sometimes they can make us feel like our privacy is being invaded. If you're looking for a way to protect yourself from these prying eyes, one option is to use a UV protection umbrella. Not only will it keep you dry in the rain, but it can also provide a shield against infrared (IR) radiation, which is what surveillance cameras use to create images.

The effectiveness of a UV protection umbrella against IR radiation depends on its fabric, density, colour, and whether it has a UPF rating. Most umbrellas are made of polyester fabric, which has been treated with a UV-resistant coating. This coating helps reflect and scatter UV rays, providing you with UPF 50+ protection, which is equivalent to wearing SPF 50 sunscreen.

When choosing a UV protection umbrella, look for one with a UPF rating of 50 or higher. This will ensure that you're getting maximum protection from IR radiation. Keep in mind that the level of protection can also vary depending on how you use the umbrella. For example, if you use it while sitting down, you'll get more protection than if you're walking.

While a UV protection umbrella can provide some defence against surveillance cameras, it's important to note that it won't make you completely invisible to them. Additionally, using items like umbrellas, LEDs, or laser pointers to block security cameras may be illegal in some places and could result in criminal charges or civil lawsuits. So, before you take any steps to block surveillance cameras, be sure to understand the laws in your area.
