In addition to removing video tapes and putting them in a player, many cameras have output jacks. Some cameras will have a Composite RCA jack that you can plug directly into Analog video gear. Sometimes cameras will have Composite out via a 3.5mm to RCA adapter. Note however that there are several standards of the 3.5mm to RCA; so make sure you have the right one for your camera.
Newer, digital, cameras may have Firewire (aka IEEE 1394), Thunderbolt, Thunderbolt2 etc. Converting these protocols to modern USB, USB-C, Thunderbolt3 or HDMI can be confusing because many of the adapters look similar but are a mess of incompatibilities. This section hopes to share knowledge on getting these protocols working with modern computers.

The yellow jack we are all familiar with now. Some cameras will have a 3.5mm jack that outputs Composite, see Video connectors for a discussion of 3.5mm adapters.
A digital standard that may be found on DV cameras, recorders and monitors. (also some VTR units)
USB-C refers to the physical connector. Many different types of signals may be carried over this connector and not all of them are compatible. This is very confusing.
