Is it legal to install spy cameras in your home? 5 things you need to know about the Hong Kong Personal Data Privacy Ordinance
**Installing spy cameras in your own home in Hong Kong is not a simple yes or no in terms of legality—the key lies in where you install them, what you are filming, and whether you have informed the relevant parties. Installing surveillance cameras in the living room or entrance of a self-occupied unit generally complies with the Personal Data (Privacy) Ordinance (PDPO); however, installing them in the bedroom, bathroom, or monitoring domestic helpers without their consent could violate the law, potentially leading to criminal prosecution.**
As a camera seller, I have seen too many customers ask me after buying the equipment: "Will there be a problem with installing it this way?" The answer depends heavily on the situation. This article isn't meant to scare you, but to help you install safely and with peace of mind.

Point 1: Hong Kong has no independent "Surveillance Camera Law"
Let's start with a common misconception. Hong Kong does not have a law called the "Surveillance Camera Ordinance"; all regulations regarding spy cameras are scattered across several laws:
- The Personal Data (Privacy) Ordinance (PDPO) — Regulates the collection and use of personal data
- Section 159AA of the Crimes Ordinance — Specifically targets voyeurism (added in the 2021 amendment)
- The Law of Tort — Civil claims for privacy infringement
The Privacy Commissioner for Personal Data (PCPD) is the main enforcement authority. They have issued the Guidelines on Surveillance and Tracking Activities, which is currently the clearest official guideline document and is worth reading directly.

Point 2: Private Units vs. Common Spaces, legal standards are completely different
Your Own Private Unit (Fully Rented)
If you are the owner and live in the entire unit alone, installing home surveillance cameras is the most lenient. You can install cameras in:
- Living room, dining room, kitchen
- Main entrance
- Outside the window facing your own balcony
The footage captured at these locations mainly consists of yourself, so the legal risk is relatively low. However, there are a few points to note: if a camera outside the window captures the private area of a neighboring neighbor, the "Principle of Fair Collection" under PDPO Article 4 may apply.
Bedrooms and Bathrooms — Explicitly Prohibited Zones
Section 159AA of the Crimes Ordinance states that any person who installs equipment to film others without consent in a "dwelling, toilet, washroom, bathroom or changing room" is guilty of an offence, with a maximum penalty of 5 years' imprisonment.
This provision was added in the 2021 amendment to fill loopholes in voyeurism laws. Note: Even in your own home, if you have tenants living in the bedroom, you do not have the right to install cameras filming them without prior notice.
Building Common Spaces (Corridors, Elevators, Car Parks)
Installation of CCTV by the Owners Corporation or management office is regulated by PDPO Principle 8, which requires:
- Posting clear signs ("This building is equipped with a closed-circuit television surveillance system")
- Stating the purpose of collection
- Limiting the retention period of recorded data
If an individual owner installs a camera at their own entrance, the angle must not capture the daily activities of other residents in the common corridor. There are documented cases: the PCPD has handled complaints where owners were sued because the camera angle captured a neighbor's entrance.

Point 3: The legal grey area of Nanny Cams and domestic helper monitoring
Nanny Cams are the most controversial application scenario in Hong Kong.
Arguments for legality:
- It occurs within the scope of your own property
- The purpose of monitoring is to ensure child safety
- Helpers are "working" in your home and do not fully enjoy the expectation of private space
Potential illegal situations:
According to the PDPO, collecting personal data (including images) from others must comply with the "fair and lawful collection" principle. Helpers living in your home have a certain expectation of privacy regarding their living space. The PCPD's stance is:
In practice, the safest approach is: Inform the helper in writing, specify the camera location and purpose, and cover only the area where children are active.
Many owners install mini spy cameras to monitor helpers, but ensure the angle does not include the helper's room; this approach is relatively secure from a legal standpoint.

Point 4: The "Reasonable Expectation of Privacy" principle — the core standard for judging privacy infringement
"Reasonable Expectation of Privacy" is the core concept Hong Kong courts use to determine if surveillance infringes on privacy.
Simply put: Would a reasonable person, in that situation, have reason to expect not to be monitored?
Several practical examples:
| Scenario | Reasonable Expectation | Camera Installation Legal Risk |
|---|---|---|
| Living room (owner lives alone) | Low | Low |
| Living room (with tenant) | Moderate | Requires prior notice |
| Helper's work area (kitchen, living room) | Low to Moderate | Requires notice + limited purpose |
| Helper's bedroom | High | Clearly illegal |
| Bathroom/Washroom | Extremely High | Criminal offence |
| Unit entrance facing corridor | Low (within own scope) | Angle must not extend |

Point 5: If your camera records a third party, your liability
Many people don't think about this: your WiFi spy camera installed in the living room, once it captures a visitor, a repair worker, or even a delivery person, you are already collecting the personal data of a third party.
According to PDPO requirements:
Collection Notice: For anyone entering your unit, you have an obligation to let them know they will be filmed. The simplest approach is to post a small notice, such as: "This unit is equipped with CCTV for security purposes."
Data Storage: Do not retain recordings indefinitely. The PCPD suggests that for general home situations, retaining footage for 7-30 days is reasonable, unless there is a specific need (e.g., retaining relevant clips after a dispute occurs).
Third-party Disclosure: Recorded data cannot be shared casually—including uploading to social media to "show off," even if the clip is just a normal daily scene. "Display purposes" is not a recognized legal use purpose under the PDPO.

Practical Recommendations for Compliant Installation
Having been in the security equipment business for many years, here are the practical steps I recommend every Hong Kong user follow:
1. Make a list Before you start, list the locations you want to monitor and the reasons, confirming that each location does not include the bathroom, bedroom, or toilet.
2. Post signs At the unit entrance or a prominent position of the camera, post a clear sign: "This unit is equipped with CCTV for security and property protection purposes." The format doesn't need to be too complex; being clear and visible is enough.
3. Inform the helper in writing If you have a foreign domestic helper, add a written clause during onboarding specifying the camera location ("living room, kitchen"), stating the purpose ("child safety monitoring and home security"), and confirming it does not include the helper's room.
4. Set up auto-deletion Most cloud cameras have a loop recording setting; it is recommended to set a 7 to 14-day auto-overwrite. If you don't need to keep the recording, don't keep it.
5. Do not install in these locations
- Anyone's bedroom
- Bathroom, toilet, changing area
- Window angles facing neighbor's property
- The helper's private space

Frequently Asked Questions
Q: I am a tenant, can I install a camera? Yes, but your landlord may have restrictions in the lease. If the lease does not explicitly restrict it, installing within the area you rent is generally fine, but it must still comply with the location restriction principles mentioned above.
Q: A friend is staying over, do I have a responsibility to inform them? From a legal perspective, they are a "guest" in your home, so you should inform them of the camera's existence. Verbal notice is sufficient; it doesn't have to be written.
Q: Can I install cameras in the workplace? Employers installing CCTV in offices is allowed under Hong Kong law, but the PCPD has specific guidelines—including informing employees, not installing in toilets, and limiting retention periods. For specific advice, please refer directly to the Guidelines on Monitoring Employees in the Workplace on the PCPD official website.
Q: I want to install a camera that is a hidden pinhole type—is that a bigger issue? The physical appearance of the equipment does not directly affect legality—whether it is legal or illegal depends on the filming location, subject, and purpose, not the device's shape itself. However, if you install a spy camera secretly in a bedroom, it is a criminal offence under Section 159AA, regardless of whether the device is visible.

Conclusion
Hong Kong's privacy laws are not meant to stop you from protecting your home, but to strike a balance between security needs and personal privacy. As long as you install in the appropriate location, have clear signage, and do not use it to monitor private spaces, most home surveillance needs can be met legally.
If you have a specific situation to confirm, the PCPD website offers a free inquiry service, or you can refer directly to the Guidelines on the Use of CCTV by Private Security Companies and Owners Corporations they have published—this is currently the clearest official guideline and is far more reliable than hearsay.
