Security and external intelligence organisations (ESO) routinely share information across borders.

Also, don't underestimate those AI-powered state CCTV systems, they are capable of far more than simply recording footage. If configured, they can perform facial-recognition matching against watchlists. Just so you know, state surveillance technology supplied mostly by China and Israel is allover Africa, and it works. The question is: in whose interests?
