I am coding a time attendance app to be used on an iPad in a secure mount outdoors (in a weather proof box).
I am thinking of blocking the home button, and leaving the iPad’s screen turned on at all times.
I was wondering if this will reduce the lifespan of the iPad by a significant amount.
Also, are there any other ideas on how to solve this problem? Proximity sensor with camera would be pretty cool. Or really just light vs dark sensing.
