So the important part what do the electrical cords connect to the camera faces forward and doesn't address which wire goes where on the back of the pull station
SLC communication voltage is usually between 13 to 17 V during operation but can be up to 32 V maximum fire alarm is life safety so it needs to be bonded/ground
I would do wireless fire alarm devices if it was absolutely impossible or impractical for a wired system otherwise definitely not, wired is superior and always will be.
