Video surveillance: What is permitted in homes & SMEs?

A camera at the entrance to your home, on your company premises or even inside a store? More and more private individuals and companies in Switzerland are turning to video surveillance. But what is actually allowed - and what is not?

We explain the legal basis, practical tips for implementation and what you need to pay attention to when it comes to data protection.

‍

Is video surveillance permitted on your own property?

For private owners

Yes, you are generally allowed to monitor your home and property with cameras - as long as you are not filming public areas.

This means:

✅ Allowed: Your own driveway, your garden, front doors, garage spaces on your own land.

🚫 Not permitted: Public sidewalks, streets or the neighboring property.

The camera may therefore only film your property, not that of third parties or public spaces.

For companies

Companies may also monitor their premises, entrances, warehouses or interiors if there is a legitimate purpose for doing so (e.g. theft protection, access control).

However, employees and customers must be informed about video surveillance (e.g. signs).

‍

Data protection: What needs to be considered?

The Data Protection Act (DSG) applies in Switzerland. This stipulates

• Earmarking: Recordings may only be used for the defined purpose (e.g. protection against burglary).
• Proportionality: No blanket permanent surveillance without a clear reason.
• Information: Signs with pictogram & contact details of the person responsible are mandatory.

Recordings must not be stored just like that. They must be checked regularly and deleted if there is no security incident.

What applies to sound recordings?

Video surveillance with sound (audio recording) is particularly sensitive. It is not permitted in most cases, as it represents a deeper invasion of privacy.

‍

Especially for SMEs: What is allowed in stores?

• Store premises may be video-monitored if, for example, theft prevention or checkout security is necessary.
• Customers & employees must be clearly informed (sign at the entrance).
• The recordings may not be misused for general employee monitoring.

Practical tips for your video surveillance

✅ Plan precisely: What do you want to monitor? Only the building entrances or also outbuildings?

✅ Select cameras with definable detection zones to avoid public areas.

✅ Document purpose & storage (especially important as a company).

✅ Ensure that notices are clearly visible.

Whether in a private home or business - video surveillance can contribute a great deal to security. It is important that you observe the legal requirements and seek advice if you are unsure.
