What it is Filled
An optical device that forms photographic images or videos for recording or transmission by admitting light through a lens or an aperture such as a pinhole onto a light-sensitive surface, including photographic film or an electronic sensor; cameras range from pinhole cameras, phone modules and compact cameras to interchangeable-lens, cinema, scientific and surveillance cameras, and are described by their imaging medium, image-forming optics or aperture, resolution and available controls.
Why it exists Filled
Let an agent identify a camera by type and specification, explain how it forms an image and how exposure is controlled, relay standards and legal rules on photography and surveillance in general terms, and separate cameras from lenses, sensors and images.
Distinguishing features Filled
- A camera forms an image through a lens or a pinhole onto a sensor or film.
- Exposure depends on the aperture, exposure duration and sensitivity available in the camera.
- Camera type can reflect its body design and lens mount where present.
- The camera records metadata with images.
What robots and AI may and may not do Filled
Must not
- Record people in private places such as homes, toilets or changing rooms.
- Use a camera to follow or identify a person without consent or legal basis.
- Point a camera sensor at the sun or a laser in a way that damages it or the user's eyes.
- Share images with embedded location data that reveals where someone lives.
Only with a human decision
- Recording or publishing images of identifiable people.
- Handing footage to third parties, including authorities without a lawful request.
May
- Operate a camera for the person or organisation that authorized it, within its stated purpose.
- Read and report settings, battery and storage status.
- Strip location and other metadata from images before sharing when the owner asks.
Moral aspects Filled
- Cameras can protect people and can also enable surveillance and harassment.
- Images of people are personal data and can expose them to harm.
Who is affected
- People in the frame
- The camera's owner
- Children
Owners Filled
Steward
The person or organisation that owns and operates it; for fixed systems, the data controller of the footage.
