I need an inspection camera

[Frankly]

But not the usual endoscope.

All endoscopes I know about have a very close and short focus range.

I need a focus range more like a webcam.

I also need 1080P resolution.

I prefer it to work with an Android tablet for the larger screen.
9" screen or bigger.
A Windows tablet will do but is less acceptable due to cost.

Suggestions please.

> Suggestions please.

Look to the plumbing or precision-metal industries. The term you are searching for is "Borescope" which is quite different from an endoscope.

One of many sources: https://www.gradientlens.com/?gclid=Cj0KCQjw8vqGBhC_ARIsADMSd1B8KNCMfkz6HQjPibfZ-Aqb-hSaG4W6v86lI1hNxRLcL1v1yKAbNxsaAkB9EALw_wcB

Spend the money you need for the purpose at hand. Going cheap will leave you frustrated!

I assume the endoscope will have its own leds for illumination. If so,
make sure that the Android tablet's USB connection has enough power to
light the leds. If it hasn't you might need to use a powered hub. If so,
check that the tablet will work with a powered hub.

Endoscopes and borescopes usually have a fixed focus and aperture, and
therefore also have a fixed field of view. You seem to be looking for
a borescope with adjustable focus and possibly aperture. Perhaps
mechanical zoom? Such cameras exist, but you won't like the price.
Look for larger borescope cameras like sewer pipe inspection,
automotive inspection, medical inspection, etc.

Why?

1080p (1920 x 1080) is wasted on a small screen unless you're
planning to enlarge the image for presentation, printing or
publication purposes. I don't see any numbers, such as the size of
the hole, magnification, sensitivity, etc, so I can't calculate how
the imager DPI (dots per inch) will translate into the viewer DPI. For
example, if you have a crude 640 x 480 imager, and upscale that to a
1920 x 1080 screen, you'll have about 3 pixels on the screen, for
every pixel on the camera.

Numbers (specs) please. Also some clue as to what you're trying to
accomplish.

Oops. 3 pixels horizontal and 2.25 pixels vertical is 6.75 pixels on
the screen, for every pixel on the camera (imager).

Think of it this way. A Win PC or Tablet (Android) with a wired camera
so I can walk and view. With a light at the camera for illuminating the
subject if needed. Look under and around things . No WiFi or bluetooth
involved.

I do not need a tiny camera to stick through a hole, I already have
two that are extremely limited in use. One is all in one and the other
is a WiFI version which is terrible operationally.

I need high res to record what I see on the screen.

Ferret Tools make several cams that work over a WiFi network it creates. Look up "ferrettools" and check them and their accessories out.
