Digital Camera World Verdict

The Inswan INS-3 has a clear USP: a detachable handheld camera that makes it easier to view objects from all kinds of angles. Educators, especially, will appreciate the ability to dynamically capture objects, experiments and models from any angle for engaging visuals. Plus it's light, portable and cheap. On the downside, you are sacrificing some image quality compared with the INS-2, but the QHD resolution it offers is still pretty good.

Taiwanese company Inswan has made three document cameras to date. INS-2 was the much-improved successor to INS-1, so you might think that the INS-3 continues this pattern. But actually, the INS-3 is something else entirely.

Ipevo Do-Cam

Not bothered about a detachable camera, but still want something smaller, cheaper and portable? The Ipevo Do-Cam is nice and compact, and with the Ipevo's feature-filled software it's useful in a broad range of classroom and presentation situations. Plus the flip button and tilting camera mean it can also step in as a webcam.

Inswan INS-2

The Inswan INS-2 document camera is a little pricier than the Inswan INS-3, and it doesn't have a detachable camera. But you are getting superior image quality (4K) from the 13MP sensor and up to 60fps frame rates. And overall, this is a very well-built and reliable document camera indeed.
