Why Informing is Mandatory: The GDPR Information Obligation

The crux of the matter lies in Articles 12 and 13 of the GDPR. These articles stipulate that anyone whose personal data is being processed (and camera images of a person constitute personal data) must be informed in advance. This is called the duty of information . The goal is transparency: people must know that they are being filmed and why, so they can change their behavior or object.

This obligation applies to anyone who uses cameras in places accessible to others: private individuals filming their driveways, shopkeepers monitoring their shop floor, and businesses monitoring their parking lots. The only exception is filming for "exclusively personal or domestic purposes," such as a camera aimed at your own enclosed backyard where no one else ever goes. As soon as you film a public road, your neighbor's property, or any publicly accessible area (including your shop), the obligation to provide information comes into effect.

Is the Sticker Itself Mandatory? The Layered Approach

The GDPR doesn't literally stipulate "you must put a sticker." The law requires that you provide information in a "concise, transparent, intelligible, and easily accessible form, using clear and plain language." In practice, this is achieved through a layered approach, with a sticker as the first, essential layer.

• Level 1: The Direct Warning (The Sticker/Sign). This is the first, quick warning you see before entering the monitored area. Its purpose is immediate signaling. This is the most visible and essential element.
• Level 2: Detailed Information (The Supplementary Explanation). This level contains all the details required by the GDPR (see next section). This can be done via a QR code on the sticker that links to an online privacy statement, an information sheet at reception, or a detailed sign at the entrance.

So, although the law doesn't mention the word "sticker," in practice it's the only logical and feasible way to meet the requirement for immediate, prior warning. The answer to the question is therefore a practical and legal "yes."

What Should Be Included on a CCTV Sticker or Sign?

A simple camera icon is often insufficient, especially in a business context. According to the European Data Protection Board (EDPB) guidelines, the information in the two layers must include the following:

On the Sticker Itself (Layer 1):

1. Clear Icon: A universally recognizable camera icon.
2. Purpose of Supervision (Brief): For example, "For the protection of property and visitors."
3. Identity of the Data Controller: The name of your company or "the residents of this property".
4. Reference to More Information: A text like "More information about your privacy rights can be found at reception" or, even better, a QR code that links to your online privacy policy.

In the Detailed Information (Layer 2 - e.g. online):

• The contact details of the Data Protection Officer (if applicable).
• The legal basis for the supervision (usually 'legitimate interest').
• The retention period of the images (standard max. 4 weeks).
• Information about the rights of the persons filmed (right of access, erasure, etc.).
• Information about whether the images are shared with third parties (e.g. police, control room).

Where and How to Place the Warning Effectively?

The effectiveness of your warning depends entirely on its placement. The rule is simple: the warning must be visible before anyone enters the area where the cameras are filming.

• For a Home: Place the sticker clearly visible on the front door, gate or fence at the beginning of your driveway.
• At a Shop: On the entrance door(s) at eye level, so that customers cannot miss it when entering.
• At a Business Premises: Large signs at each vehicle entrance gate and each staff and visitor entrance.
• Inside a Building: If you are filming specific areas inside (e.g. a warehouse, but not the canteen), place a warning at the entrance to that specific area.

The Risks of Not Informing: More Than Just a Fine

Failure to provide a proper warning can have far-reaching consequences beyond just a possible fine.

1. Illegally Obtained Evidence: Suppose you film a theft, but you don't have a warning sticker. A judge could rule that the evidence was unlawfully obtained because you violated privacy laws. The footage would then be worthless, and the perpetrator would go free.
2. Fines from the Dutch Data Protection Authority: The Dutch Data Protection Authority can impose fines of up to thousands of euros for private individuals and up to 4% of annual turnover for companies.
3. Complaints and Damage Claims: Filmed persons (neighbours, customers, staff) can file a complaint with the AP or even initiate civil proceedings to claim damages.
4. Reputational damage: For a company, if it becomes known that secret filming is taking place, this can lead to serious reputational damage and a loss of trust among customers and staff.

You've invested in a professional system for collecting evidence. Without the small investment in a proper sticker, you're undermining the primary purpose of your entire installation.

Combine the legal warning of a sticker with the physical warning of a camera. This type of bullet camera is designed to be seen. The visibility of the camera reinforces the message on the sticker, creating a powerful deterrent effect that discourages opportunistic burglars.

The Dual Function: Prevention and Transparency

A correct warning sticker has a double psychological impact.

• For Unwanted Visitors (Prevention): The sticker sends a clear message: "Be aware of this, the chance of remaining anonymous is minimal." For the 60-80% of burglars who are opportunistic, this is often enough to choose another, easier target. It projects professionalism and preparation.
• For Desired Visitors (Transparency): For customers, guests, and staff, the sticker demonstrates transparency and care. It communicates: "We take your and our safety seriously and do so in an open and honest manner." This builds trust, unlike the unrest that hidden cameras can cause.

Practical examples: Private vs. Business

The requirements are the same for everyone, but the implementation differs.

Private Use (Town House/Detached House)

A sticker on the front door and/or gate is usually sufficient. This should state that the purpose is "protection of property" and that the responsible party is "the residents." A QR code is a plus, but a full privacy statement is less likely to be expected from private individuals, although it is recommended.

Business Use (Shop/Office)

The requirements are stricter here. A professional sign at every entrance is a must. A QR code that links to a specific page on your website with the camera protocol is the most professional and legally sound solution.

When monitoring large company premises with a PTZ camera, clear signage at the gates is crucial. Because these cameras can zoom and track, the potential privacy impact is greater. A sign that indicates the presence of an advanced tracking system, linked to a detailed online protocol, is essential for legal protection.

Conclusion: The Sticker as an Essential Part of your System

So, is a CCTV sticker mandatory? Yes. It's not an optional accessory, but a fundamental component of a legal and effective security system. Without proper signage, your system is an expensive piece of hardware that could land you in legal trouble.

Don't consider the sticker an annoying obligation, but a smart tool. It's your first, cheapest, and often most effective preventative measure. It demonstrates that you take both security and privacy seriously. It ensures your evidence holds up in court and protects you from hefty fines and claims. In short, a proper sticker transforms your camera system from a passive recorder into a legitimate and proactive security tool.
