Do I need to expense this cost for the LLC, or leave it alone?

[Bienes Raices]

The portable alarm (lasershield) that I use is billed to my personal credit card. The alarm was in a house that I own in an LLC for a few months while the house was vacant.

In order to avoid co-mingling, do I need to do an expense report for the time period/monetary amount that the alarm was used at the LLC'd property? This is kind of a gray area because the alarm is also used at houses that I own in my own name when they're vacant. I currently own one house in an LLC and the rest are still in my name. Thanks.
