A Singaporean trainee doctor has pleaded guilty to secretly filming hundreds of colleagues in hospital toilets and showers across three major Melbourne hospitals, in one of Australia's largest workplace privacy violation cases.

Ryan Cho, 28, pleaded guilty before the Melbourne Magistrates' Court to 13 consolidated charges, including stalking, installing optical surveillance devices, and producing intimate images. The original investigation had resulted in 910 charges, which prosecutors later combined into 13 representative offences as part of the legal proceedings.

According to investigators, police seized multiple electronic devices from Cho's residence, including a laptop, hard drives, and mobile phones. Forensic examinations reportedly uncovered more than 10,000 intimate photos and videos involving over 500 victims, many of whom were colleagues filmed without their knowledge while using staff toilets and showers.

Authorities allege the offences occurred between 2021 and 2025 at:

• Austin Hospital
• Royal Melbourne Hospital
• Peter MacCallum Cancer Centre

The investigation began after hospital staff discovered a hidden mobile phone concealed inside a mesh bag in a staff restroom. The device was actively recording at the time it was found, leading to a wider police investigation.

Cho has been suspended from practising medicine and remains on strict bail conditions. His sentencing hearing is scheduled for November, when victims are expected to deliver impact statements to the court.

Why This Story Matters

Cases involving hidden cameras are often associated with hotels, vacation rentals, or changing rooms. However, this incident highlights an uncomfortable reality: privacy violations can also occur in workplaces, hospitals, offices, universities, and other places where people naturally expect to feel safe.

Modern hidden cameras have become increasingly difficult to detect. Many are disguised as everyday objects, including:

• Phone chargers
• Smoke detectors
• USB adapters
• Wall hooks
• Alarm clocks
• Air fresheners

Some devices are capable of recording continuously, while others can stream footage remotely over Wi-Fi.

Protecting Your Privacy

No technology can guarantee the detection of every concealed camera, but building simple privacy habits can significantly reduce your risk.

If you're entering an unfamiliar hotel room, Airbnb, office, dressing room, or shared accommodation, taking a few moments to inspect the space is a practical precaution.

DETEKCAM helps users perform quick privacy checks using multiple detection methods, including:

• AI Lens Detection
• Infrared (IR) Detection for night-vision cameras
• Magnetic Field Detection

These tools are designed to help users identify suspicious devices and increase awareness before using unfamiliar spaces.

Privacy Should Never Be an Afterthought

The Melbourne case is a reminder that hidden-camera crimes can happen in places where trust is expected the most. Whether you're traveling, working, or simply using a shared facility, staying aware of your surroundings is one of the simplest ways to protect your privacy.

Privacy isn't about paranoia, it's about preparedness.
