Sarcasm seems to escape some folks
I've formed for multiple hundreds of thousands of cubic yards of concrete and know more about it off the top of my head than most folks do. It's a far deeper and more complex subject than you would imagine
I do hope your wall endures but introducing rigid elements into old lime-mortared stonework can actually cause it to fail sooner and more catastrophically- another deeply complex subject which very few people understand well anymore since portland mortars are all that's been in use for well over 100 years, but weren't around 200 years ago. If it's a dry-stack wall you may be OK.
Can't say I'm deeply knowledgeable about cameras and computers and coding,
but this is my bailiwick and I've a working lifetime of experience in it
