Surveillance cameras are everywhere, from homes to public spaces, and they can be a useful security tool. However, they can also raise privacy concerns and be vulnerable to hacking. If you want to mess up surveillance cameras, there are a few methods you can try, but be aware that some of these may be illegal and carry consequences. Here are some ways to interfere with surveillance cameras:
- Using infrared lasers or LEDs: Shining a bright LED light or infrared laser directly into the camera lens can obscure your identity, but it requires precision and may not always be effective.
- Physical obstruction: Covering the camera lens with tape, petroleum jelly, or a bag can block the camera's view.
- Disabling the camera: This may involve cutting wires or using camera jammers, but it is illegal and can result in criminal charges.
- Hacking: While it is possible to learn how to hack into a camera, this is illegal and will likely result in legal consequences.
- Natural obstruction: Planting trees or shrubs, or using fences or curtains, can block the camera's view naturally.
- Confusing the camera: Placing moving objects, such as flags or windmills, can confuse cameras with motion detection, causing them to record only the objects and not your movements.

What You'll Learn
Shine a powerful LED light directly into the camera lens
Surveillance cameras are a common sight nowadays, from malls to street corners. While these cameras are often used to keep patrons in check, they can also be used to invade privacy. If you want to avoid being identified by a surveillance camera, one method is to shine a powerful LED light directly into the camera lens. Here are some tips to effectively use this technique:
- Use a small, powerful LED light that you can easily carry and store.
- This method works best in the dark or in enclosed spaces, so plan your actions accordingly.
- Identify the exact location of the camera and shine the light directly into the lens to create a lens flare, making it difficult for the camera to capture your face.
- Be precise and quick in your actions to avoid revealing your face. Do not shine the light onto your face.
- Hold the light steady and avoid dropping the beam from the camera lens.
- Be aware that this method will alert any vigilant guard to your presence, so act discreetly.
- For a more permanent solution, you can attach infrared LEDs to your clothing or craft an LED "mask" to heavily obscure your face. Ensure the lights are bright enough to blot out your face but not so bright that they cause discomfort.
It is important to note that blinding a surveillance camera will only obscure your identity, not your presence. While this technique can be effective, it may not always guarantee complete anonymity. Additionally, always ensure that your actions are legal and do not cause harm to others or their property.

Use an infrared laser to blind the camera
Surveillance cameras can be blinded using an infrared laser. This method is more subtle than shining a bright light, but it requires precision. The laser must be pointed directly into the lens of the camera; if the laser-point slips, the camera will catch your face. This method can be used during the day or night, although it may be more effective in the dark.
It is important to note that this method has limitations. It requires focus and only works on one camera at a time. Additionally, anything that comes between the laser and the camera will instantly un-blind the camera. It is also challenging to gauge the effectiveness of this method as you cannot tell if the laser is aimed correctly from your end. Furthermore, there is a risk of eye damage if the laser is pointed directly into your eye, so consider wearing protective glasses.
To blind a camera with an infrared laser, follow these steps:
- Identify the location of the camera.
- Quickly and efficiently point the infrared laser directly into the lens of the camera.
- Ensure that nothing comes between the laser and the camera, as this will instantly un-blind the camera.
- Be aware that you cannot gauge the effectiveness of this method from your end, so act quickly and precisely.
- For added protection, consider wearing dark glasses to protect your eyes from the laser, but do not rely solely on them.
It is worth noting that blinding a surveillance camera with an infrared laser is not legal in most jurisdictions. Additionally, most standard laser pointers do not have sufficient power to damage the sensor of a security camera. However, a more powerful laser can cause sensor damage if aimed extremely accurately and steadily.

Cover the camera lens with tape or petroleum jelly
If you're looking to mess up surveillance cameras by covering their lenses, two options are tape and petroleum jelly.
Using tape to cover a camera lens is a straightforward method. It involves placing tape directly over the lens, obstructing the camera's view. This approach is simple and can be done with various types of tape. However, it is important to note that this may not be a long-lasting solution as tape can be easily removed.
As for petroleum jelly, it is not advisable to apply it directly to a camera lens. Instead, consider using a clear filter or cling wrap stretched over the lens, providing a barrier between the jelly and the lens. You can secure the cling wrap with a rubber band, ensuring there are no holes. With the barrier in place, you can then smear petroleum jelly onto it. This technique is less likely to damage the camera lens and can be easily removed later using alcohol wipes.
The amount and direction of petroleum jelly applied will influence the level of abstraction in the resulting images. Start with a small amount and gradually add more to increase the effect. Additionally, the direction in which you apply the jelly will impact the final image, so feel free to experiment with different patterns and shapes.
Both tape and petroleum jelly can effectively obstruct a surveillance camera's view, but it is important to consider the potential consequences and the temporary nature of these methods.

Hack into the camera
Hacking into surveillance cameras is alarmingly simple. The most common way to gain access is by guessing the username and password of the device's administrative account. Consumer-grade cameras, or those that people install themselves, are more susceptible to being hacked. This is because people often use default passwords and usernames, which are easy for hackers to guess.
To prevent this type of hack, use a strong password that is hard to guess. A good password should be long and complex, with a random phrase or string of characters, including numbers, symbols, and a mix of uppercase and lowercase letters. It is also important to avoid using any personally identifiable information, such as names or birth dates, as hackers can often obtain this information from public social media profiles.
In addition to a strong password, you can also set up a password manager. Password managers generate strong, random passwords for your digital accounts, securely store and remember them, and even automatically insert them into login prompts.
Another layer of security is two-factor authentication (2FA). With 2FA, you will receive a single-use passcode via text message, phone call, email, or authentication app each time you log in to your account. Even if a hacker has your password, they will not be able to access your camera without the randomly generated code.
It is also important to keep your camera's firmware up to date. Manufacturers that prioritise security will regularly release firmware updates to fix software bugs and patch security vulnerabilities. Some cameras will automatically download and install these updates, while others may require you to manually check for and install them.
By following these steps, you can significantly reduce the chances of your surveillance cameras being hacked.

Cut the camera's wires and cables
Cutting the wires of surveillance cameras is a common tactic used by burglars to avoid being caught on tape. This method can be effective in disabling CCTV cameras, but it is not always successful, as some cameras have backup batteries or alternative power sources that allow them to continue recording even with cut wires.
If you are considering cutting the wires of a surveillance camera, it is important to understand the different types of cameras and their wiring systems. Most wired cameras do not have a backup system or battery, so cutting their wires will likely disable them. However, some cameras record on SD cards and have backup batteries, allowing them to continue recording for a short period until the battery runs out or a replacement cable is connected.
Wireless cameras, on the other hand, may still function with cut wires as long as they have a connection to the internet and a battery. If their connection is through an Ethernet cable, cutting it will jam the camera and prevent it from sending signals to your app, effectively disabling it.
Before cutting any wires, it is crucial to assess the type of camera and its wiring. Some cameras have internal backup batteries, which allow them to continue recording even with cut wires, keeping your home and family safe. Additionally, consider the placement of the camera, as outdoor cameras are more vulnerable to damage and wire cutting due to exposure to bad weather, animals, and potential criminals.
If you are determined to cut the wires of a surveillance camera, be aware that it may not be an easy task. The wires may be encased in multiple layers of insulation and shielding, requiring careful stripping without damaging the core. Additionally, repairing or splicing the wires back together can be complicated and may void the camera's warranty.
