So can anyone explain why I'm having such drama sending "+++" to the ESP? by Serial1.println("+++")

is "+" a special character that should be sent like this perhaps? Serial1.println("\+\+\+") (not in a position to try this right now so thought I'd ask)

thanks for any help

Serial1.println("\+\+\+")

No, the + is not a special character needing to be escape.
So, the problem maybe elsewhere ...

the data has to be +++ on it's own with no invisible characters i.e \r\n.

Both NL & CR on the Arduino IDE serial monitor and Serial1.println was the cause.

Serial1.print("+++") works in my sketch

THIS IS COOL
In the video speed 921600 baud, but today I installed it on 2,000,000

Now the camera is much faster!!!

I tested ESP32CAM but now my camera is working as well.
