We did an analog tech version of that with a VHS camcorder on my parents’ house. The only time we had to use it, we had both an inside and outside view that just missed the one key place we were about to work on. :) It was good enough to still be helpful (we were able to guess based on the likely path of the NM-B (“Romex”) in the spots we could see), but it was amusing how we missed the key spot by inches twice.
