As incidents of surveillance camera data leaks continue to emerge both globally and in Vietnam, users are growing increasingly uneasy about the potential exposure of sensitive personal and family footage.

Constant risk of surveillance camera data leaks

Since 2021, Ms. H.T. from Dong Da District, Hanoi, has relied on surveillance cameras to monitor her shop and private residence. While she finds the system convenient for managing staff and assisting family members in real time, she remains anxious about the potential leak of private footage.

"Because of these concerns, I signed a contract with a reputable provider for our home setup. Still, I’ve only installed cameras outside the house - in the yard, front door, and living room. I absolutely avoid placing cameras in bedrooms or private spaces," she explained.

H.T.'s concerns are shared by many, especially as a large portion of surveillance devices available in Vietnam are of unclear origin. While she has yet to suffer a breach, others may not be as fortunate - especially when using generic or unverified brands.

Globally, protecting data from these digital “eyes” has become an urgent issue. Numerous high-profile leaks have occurred, with hackers infiltrating camera systems in hospitals, schools, and private homes - resulting in unauthorized distribution of sensitive footage.

In Vietnam, the use of internet-connected surveillance cameras by government agencies, businesses, and individuals has surged in recent years. However, this growing trend has coincided with a rise in personal data leaks. Several incidents have involved private footage being illegally collected and posted on social media, causing public alarm and threatening social security.

In one 2020 survey, up to 70% of surveillance cameras had not been updated with new passwords. In 2023, some hackers advertised access to Vietnamese cameras - boasting control over more than 100,000 devices. Shockingly, access to 15 cameras was priced at only 800,000 VND (about 32 USD).

How to use surveillance cameras safely

Experts predict that in 2025, Internet of Things (IoT) devices - especially those with weak security - will be prime targets for cyberattacks.

In a February 2025 interview with VietNamNet, Vu Ngoc Son, Head of Technology at the National Cybersecurity Association, warned that along with APT (advanced persistent threats) and ransomware attacks, targeting IoT devices like security cameras will be a major trend this year.

"Security cameras are an ideal target for hackers because they’re widely installed, often internet-connected, and offer access to sensitive visuals and audio. Unlike computers, cameras typically lack strong cybersecurity defenses," Son explained.

To mitigate risks, experts urge users to select reputable camera brands with well-defined privacy and security policies. Avoid using products of unclear or unreliable origin.

When installing cameras, users should immediately change default passwords to strong ones - using a mix of uppercase and lowercase letters, numbers, and symbols. Weak passwords make it easy for hackers to break in.

Manufacturers regularly release software updates and security patches to fix vulnerabilities. Users should ensure their devices are always updated to the latest version to reduce exploitation risks.

If remote monitoring isn’t necessary, experts recommend disabling internet access on the camera system - particularly for devices installed in public or shared areas.

For cloud storage, users should choose services from trusted providers that comply with international safety standards and offer clear commitments to data protection.

Additionally, avoid installing cameras in areas that may violate privacy - such as bedrooms or bathrooms. This protects both safety and personal rights.

Users are also advised to regularly check access logs to detect suspicious activity early and respond accordingly.

Finally, for the Wi-Fi networks that cameras rely on, ensure strong password protection and enable WPA3 encryption. This helps prevent unauthorized camera access through insecure networks.
