An external recorder takes the video signal from a camera over HDMI or SDI and records it in an editing-friendly format such as ProRes, usually to an SSD or card. Many also act as a monitor, so you get a larger screen and tools like focus peaking in one unit.
The six recorders below run from 5 inch monitor-recorders to a rack-style deck. Sizes, codecs and connections come from each product’s listing page, and listings sometimes disagree, so we say so where they do. We have not used these recorders ourselves. Claims are the makers’ own.

External Recorder FAQ
Do I need one?
Only if your camera cannot record the codec, bit depth or length you want internally.
Is a recording monitor the same as a field monitor?
A recording monitor also saves the footage. A plain field monitor only displays the picture.
