I want a little camera to put through holes in floorboards, to check for leaking pipes and the like. USB, attached to the laptop should do the trick, but I have tried one before and it was pretty crappy with a very small depth of focus.
Can anyone recommend one that actually works well? Preferably not too expensive.
fwiw a small lens would change the focal field.
The issue with depth of focus is due to the low light level. to be small enough any leds that illuminate the scene are going to be very weedy. Brian
There's no simple answer to this. I have several, they all have limitations. It is sometimes helpful to have a separate light source. It is very often more difficult than you expect to get a good angle of view on things. It's usually easier to get a "straight ahead" view than a "sideways" view. As you have found, if you start with high expectations you will be disappointed.
