How to realize video recording from analog camera without PC?

Question

CCTV

Hello. There is a small analog camera ZK-208C, used as a video peephole, a monitor was directly connected to it and it showed everything that was happening.
It is necessary that the video from the camera is constantly recorded on some media: USB flash drive, flash card, external hard drive, etc. without connecting to a PC. Interested in an inexpensive option (up to 3k rubles)
I used to see small boards that just captured video from an analog camera and wrote to an SD flash card, but now I can’t find it.
Tell me which way to google.
Sincerely, Stanislav.
