ZuckOff Turns Your Phone Into a Detector for Nearby Camera Smart Glasses
Smart glasses are becoming more capable, but their cameras are also creating a new privacy question: how can people nearby know when someone is wearing a device capable of recording them?
A new app called ZuckOff is offering one possible answer. Developed by Polish programmer Pawel Szydlowski, the app uses Bluetooth signals to identify supported camera-equipped smart glasses that may be nearby.
The idea is relatively simple. Instead of trying to determine whether someone is actively recording, ZuckOff looks for identifying Bluetooth signatures associated with devices such as Ray-Ban Meta, Oakley Meta and Snap Spectacles. The app then alerts users when it detects a compatible device.
That distinction is important because the technology cannot tell a user with certainty that a person is recording at that exact moment. It is primarily a proximity and device-detection tool.
What Is ZuckOff?
ZuckOff is a mobile app designed to identify nearby camera-equipped smart glasses through Bluetooth.
According to its website, the app listens for Bluetooth advertisements from compatible devices and compares their manufacturer signatures with a database of known hardware. It can identify devices associated with Ray-Ban Meta, Oakley Meta and Snap Spectacles, among others.
The developer says the app does not require an account and processes its detection system on the phone rather than sending the information to a remote server.
Users can also see evidence behind individual detections, allowing them to understand why the app has flagged a particular device.
Why Was ZuckOff Created?
The app arrives as camera-equipped smart glasses face increasing scrutiny over privacy.
Unlike a conventional smartphone, smart glasses can look almost indistinguishable from ordinary eyewear. A person may therefore have difficulty knowing whether someone nearby is carrying a camera.
Meta's AI glasses include a capture LED designed to indicate when photographs or videos are being captured. Meta says the light is intended to make recording visible to people around the wearer.
Meta has also introduced safeguards intended to prevent users from defeating the indicator. The company says newer glasses can disable their cameras when the capture LED is blocked or when the device detects that the LED has been physically tampered with.
Despite those measures, concerns about covert recording have continued to attract attention.
That has created space for independent tools such as ZuckOff, which approaches the problem from the perspective of the person potentially being recorded rather than the person wearing the glasses.
How Does the ZuckOff Detector Work?
The technology relies on Bluetooth rather than the phone's camera.
ZuckOff listens for Bluetooth signals emitted by nearby devices. Some smart glasses broadcast identifiers that can reveal their manufacturer or device family.
The app's website lists several signatures that it uses as detection signals, including identifiers associated with Luxottica devices, Meta wearables and Snap Spectacles.
The basic process looks like this:
- Open the ZuckOff app.
- Allow Bluetooth-related access required for scanning.
- The phone searches for nearby Bluetooth advertisements.
- ZuckOff compares detected signatures with known smart-glasses identifiers.
- A matching device is displayed as a potential camera-glasses detection.
