Surveillance cameras could just put everything in focus at all times.

Surveillance cameras could just put everything in focus at all times.
- dTal 3y agoYou can only do that with a very small aperture - otherwise you're capturing the scene from slightly different angles across the aperture, and if you want all those images from different angles to "line up" you have to select a depth of interest. This is why focus is a thing. A very small aperture is not so good for surveillance, because it doesn't let much light in. Good low light performance or wide depth of field: choose one.
