The smart glasses detector application warns if you are being recorded

Smart glasses are designed to integrate. Most of the time, they look like a normal pair of glasses. The difference is that some models can silently take photos or record videos without anyone nearby noticing.

As these wearable cameras begin to appear in everyday places, more people are wondering when they could get in front of the camera. That concern helped inspire a new Android app called Near Glasses, which lets you check if there are smart glasses nearby.

The idea behind the app is simple. If a nearby device transmits a Bluetooth signal linked to smart glasses, the app attempts to detect it. For people concerned about hidden cameras in public spaces, even a small warning could help them be more aware of their surroundings.

Why smart glasses raise privacy concerns

Smart glasses are designed to integrate. Unlike a phone or camera, they often look identical to regular glasses. That means someone could be filming without anyone around them noticing.

Modern versions of these devices can capture photos, record videos, and even live stream. Some models also connect to artificial intelligence tools that can analyze what the user sees. Privacy advocates say the biggest problem is visibility. When someone takes out a phone to record, people usually notice.

With smart glasses, the camera can be hidden in plain sight. As a result, conversations about consent and privacy are becoming more urgent as wearable cameras become more widespread.

How the Nearby Glasses App Works

Nearby Glasses work by searching for Bluetooth signals that devices transmit to connect with phones and other hardware. Each manufacturer uses unique Bluetooth identifiers. The app listens to those signals and compares them to known identifiers of companies that produce wearable devices. If the application detects one of those signals, it alerts the user.

This is how the process works:

• The app scans nearby Bluetooth devices in real time
• Check each sign with identifiers from known manufacturers.
• If a match appears, the user receives an alert

Currently, the app focuses on devices made by companies like Meta and Snap. Users can also add additional Bluetooth identifiers to expand what the app detects. That allows the tool to detect more types of wearable technology. To keep scanning continuously, users need to enable a foreground service in the app and press Start Scan. A debug log then shows the scanning activity while the application is running.

Why the developer created the app

The app was developed by software creator Yves Jeanrenaud, who says he created it after seeing how wearable cameras were used. On the project page, Jeanrenaud described smart glasses as a major privacy concern. He believes the devices could open the door to more recordings without consent.

He also noted reports of smart glasses appearing in sensitive situations. Those examples include cases where handheld cameras were allegedly used during immigration screening or in situations where people were filmed without permission.

According to Jeanrenaud, the app represents what he calls a form of technological resistance. In other words, use technology to deal with technology. Still, even he admits that it may only solve part of the problem.

The app is useful but not perfect.

Like any detection tool, Nearby Glasses has limitations. Bluetooth signals don’t always reveal exactly which device is nearby. For example, a device from the same manufacturer could trigger an alert. That means a headset or other device could appear as a possible pair of smart glasses.

False positives are possible. However, those alerts still give users greater awareness of nearby devices that could be capturing data. At the moment, the application is only available for Android. The developer has said that an iPhone version could appear in the future, depending on time and demand.

Ways to stay safe with smart glasses

Smart glasses are becoming more common. While tools like Near Glasses can help, awareness is still the best defense. Here are several ways to protect your privacy.

Pay attention to the visible indicators on the camera.

Some smart glasses include small LED lights that turn on while recording. If you notice a light in someone’s frames, they may be filming.

Speak up if you feel uncomfortable

If you suspect that someone is recording you in a private setting, you can ask them directly. Many people stop when confronted.

Avoid sensitive conversations in crowded areas

Wearable cameras thrive in public settings where people are distracted. Avoid discussing personal information in places where recording could occur.

Turn off Bluetooth visibility on your own devices

Limiting the signals your devices transmit can reduce the ease with which others track or scan your hardware.

Kurt’s Key Takeaways

Smart glasses represent a strange moment in the evolution of technology. On the one hand, they promise comfort. People can capture moments hands-free or access digital information instantly. On the other hand, they blur the line between everyday life and constant surveillance. Apps like Nearby Glasses show that some people are already stepping back. They want tools that reveal when hidden cameras might be nearby. However, technology alone will not resolve the debate. The real question is how society decides to balance innovation with basic expectations of privacy.

And that leads to a bigger question. If cameras can be hidden in regular glasses, should people be required to reveal when they are recording you? Let us know by writing to us at Cyberguy.com.
