Anyone use cams to monitor they're measuring devices?

I've found that the safest and easiest way to gather the temp and EMF is to simply put them on a table/or against a wall and point a camera directly at them. With a flashlight dropped pointing at them so that the T1 Therm is easy to see.

I play alot of solo and it just seemed to be too much of a risk to sit in the ghost room with those in hand when I could get those measurements, ghost orbs, and DOTS from my van... until the ghost yeets my camera into oblivion. 🤣

Then I grab my UV and spirit box to be more productive while I scramble to set it back up😅

I figure I'm not unique in the slightest with this idea but wanted to see if everyone did it or not.
