before you get a ESP32 CAM (I love em) consider one with an external antenna

it may be wise to read this https://www.reddit.com/r/esp32/comments/r7kqtt/esp32cam_supe...

I got fairly bad frame rate until I tried some of the advise

Yes, from my experience with this project the external antenna is a must. I've update the README with a link to the one I used.

Can you recommend an exact model?

I'm afriad not, I bought a load of esp32 cams with out the external antenna - hit a problem with the frame rate and fixed it from the advice from the link

for my other projects I did use a ESP32 with an external antenna, but they did not have a camera port

These things are so cheap just buy one and see (unless time is an issue)

edit: the OP did add this link to one https://www.aliexpress.com/item/1005001468076374.html - note this does not have a usb connector - you can get them separately

In my case it went from a patchy 1mbps to a stable 20mbps right away, according to my router's admin page - right after resoldering the resistor and connecting the antenna.

Resoldering the 0 ohm resistor was like an adventure, but somehow managed to connect the correct pins. The end result looks like following:
