You might have good need for a security camera but wear and tear on the garage doors and openers is definitely not one.

Someone mentioned 10 years life span for the opener of steady use - which in itself is a trivial expense, maybe a couple hundred bucks to replace including labor.

However, my experience it's actually 2X or 3X that amount of time, making the issue totally crazy to think about. Both of the houses I've owned have had at least 15 years and the current one, almost 30 years of use without failure (one garage door spring replaced, no problems with the 28 year old openers!)

Wear and tear? That's just just silly thinking. Just open and close the doors whenever you need to.
