Why are legal aspects so important in digital signage?

Digital signage systems have become an integral part of modern communication—but with digitalization come increasing legal requirements. Data protection, copyright, and regulations for outdoor advertising play a central role. Those who are well informed in this area can protect themselves and their customers from costly mistakes and position themselves as responsible partners.


Overview of legal principles

Digital signage combines technology, content, and data processing—and thus touches on numerous areas of law. Errors or ignorance can lead to warnings, fines, damage to your image, or business interruptions. It is therefore essential for resellers and operators to familiarize themselves with the most important legal framework conditions and to seek expert advice in case of doubt.


Data protection: What do you need to bear in mind?

1. Personal data and GDPR

As soon as digital signage systems process personal data (e.g., in interactive applications, camera use, analysis of movement data), the provisions of the General Data Protection Regulation (GDPR) apply. Even seemingly harmless applications—such as visitor counting, touch feedback, or facial recognition—can fall within the scope of the GDPR.

Key principles:

  • Transparency:
    Users must be informed about data collection (e.g., through notices on the device, privacy policy on the display, or via QR code).
  • Purpose limitation:
    Data may only be used for the specified purpose. For example, movement data collected may not be used for advertising if it was only collected for visitor counting purposes.
  • Data security:
    Protection against unauthorized access through technical and organizational measures. These include encryption, access restrictions, and regular updates.
  • Order processing:
    When working with service providers (e.g., cloud hosting, maintenance), a data processing agreement is required. Check whether your service providers are GDPR-compliant.
  • Data minimization and storage limitation:
    Only collect necessary data and do not store it longer than necessary.

Tip:
Work with data protection officers and document all processes. Conduct regular data protection impact assessments—especially for new or sensitive applications.

Practical example:

A retail chain uses cameras to count visitors. A clearly visible notice at the entrance provides information about data collection and its purpose. The data is anonymized and not linked to other systems.


Copyright: Using content in a legally compliant manner

1. Licenses for images, videos, and music

All content used on digital signage must be legally licensed. This applies to photos, graphics, videos, and music. Copyright infringements can result in expensive warnings and claims for damages.

Basic rules:

  • Prefer your own content:
    Your own images and videos are legally the safest option. Even with content you have created yourself, be mindful of third-party rights (e.g., people, brands, buildings depicted).
  • Stock material:
    Only use licensed sources and observe the terms of use. Check whether the license covers use on digital signage (e.g., commercial use, transfer to third parties).
  • GEMA and other collecting societies:
    A fee may be payable for the use of music and video. Register the use and pay the required fees.
  • YouTube, social media, etc.:
    Most platforms do not allow public playback on digital signage. Check the respective license terms carefully.

Tip:
Document all licenses and inform your customers about the importance of rights clearance. Maintain a central license register and update it regularly.

Practical example:

A gym wants to show music videos on its displays. The operators clarify whether the GEMA fees are covered and obtain the necessary licenses for each video.


Outdoor advertising: Permits and regulations

1. Public spaces and buildings

Special regulations apply to the installation of digital signage in outdoor areas (e.g., LED walls, shop window displays):

  • Building permit:
    In many municipalities, a permit is required for outdoor advertising installations. The requirements vary depending on the state, municipality, and location.
  • Light emission:
    There are guidelines regarding brightness and operating hours to avoid disturbing residents and traffic. Strict rules apply, especially in residential areas or on roads.

  • Special requirements apply to listed buildings. Changes to the facade or appearance must be approved.
  • Road safety:
    Advertising installations must not distract or dazzle road users.
  • Design regulations:
    Many cities have their own guidelines regarding the size, color, animation, and placement of outdoor advertising.

Tip:
Contact the relevant authorities at an early stage and obtain all necessary permits. Allow sufficient time for the approval process and check whether neighbors or residents need to be involved.

Practical example:

A retailer wants to install a large LED wall on the main street. He applies for a building permit in good time, submits a lighting report, and adjusts the operating hours to the city's specifications.


Further legal obstacles

  • Advertising law:
    Special advertising restrictions apply to certain products (e.g., tobacco, alcohol, medicines).
  • Protection of minors:
    Content must be suitable for the target audience and location.
  • Accessibility:
    Public information systems must be designed to be accessible (e.g., high-contrast display, read-aloud function).
  • Contractual protection:
    Clear regulations regarding responsibilities, maintenance, content, and liability are mandatory.

Common mistakes and how to avoid them

  • Use of unlicensed images or music:
    Check each file for rights and licenses before use. Only use professional sources.
  • Lack of data protection notices in interactive systems:
    Ensure that notices are visible and that your privacy policy is transparent.
  • Installation without official approval in outdoor areas:
    Obtain all permits before starting construction. Violations may result in dismantling and fines.
  • Unclear responsibilities for content and system operation:
    Specify in the contract who is responsible for content, updates, and maintenance.

Tips for resellers: How to advise your customers in a legally compliant manner

  • Offer initial legal advice or work with specialized attorneys.
  • Create checklists for data protection, copyright, and outdoor advertising.
  • Train your customers in dealing with licenses, permits, and disclosure requirements.
  • Document all processes and point out risks.
  • Stay informed about changes in legislation and adjust your advice regularly.

Trends and current developments

  • Data protection is becoming more complex:
    New technologies (e.g., AI, facial recognition) place new demands on transparency and consent.
  • Automated license verification:
    Systems for managing and controlling content licenses are becoming increasingly important.

  • Cities are developing new regulations for digital advertising installations to protect the cityscape and traffic safety.

  • : Accessibility is becoming a key focus. More and more public projects are relying on inclusive, easily accessible digital signage solutions.
