camera
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.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
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.
An optical instrument that captures images by focusing light through a lens onto a light-sensitive surface, historically photographic film and today an electronic sensor; cameras range from phone modules and compact cameras to interchangeable-lens, cinema, scientific and surveillance cameras, and are specified by sensor, lens, resolution and controls.
What it is for: Capturing still and moving images.
It can be identify type and specifications; explain image formation and exposure; compare cameras for a purpose; relay rules on photography and surveillance in general terms.
Distinguishing features
Forms an image with a lens on a sensor or film
Exposure by aperture, shutter and sensitivity
Type follows body and lens mount
Records metadata with images
What it looks like
A body with a lens, viewfinder or screen, shutter release and controls; or a small module in a phone or device.
Physical character
sensor size: a few millimetres to full frame 36 by 24 mm - and larger in medium format
resolution: 1-100 and above megapixels - by model
shutter speeds: 1/8000 to 30 s - typical range
How it is recognised
Lens, sensor or film, shutter and controls
Type by body: compact, mirrorless, single-lens reflex, cinema, action, phone module
A lens alone, a sensor alone or an image are separate entries
