The camera sensor is housed in a very rugged, small black metal box, with a standard camera mount thread on both the top and bottom. The lens has screws to lock the focus and zoom in place once set. This is not a camera for live action, as it is difficult to focus, but one you set up, lock in place and leave. The camera has a USB plug, and operates as any other web camera.

When the COVID-19 pandemic stuck last year I had to set up my home office for teaching by video-conference. However, I decided I should not have anything out of reach of a typical teacher, or student, as education should be accessible to everyone. So I used a low cost, low speed broadband connection, a modestly priced laptop, and a consumer grade web camera. This worked fine, especially with Zoom. However, I decided it was time for an upgrade.
