⁣Please Note: to hear the beeping sounds i reference in the beginning of this video, you will need earphones or put the cell phone to your ear to hear it.

A week or so ago my husband was awoken by a loud bang and asked me to check the footage. While checking, I came across some 'beeps' i couldn't place.

So it was suggested I check the only thing in the room that could make that beeping noise (CO2 monitor) to rule it out.
Interestingly enough, upon checking the sound in the video with a meter, I found that the sound, is in the same key but a few octaves lower than the actual monitor.

Given the amount of activity and other documented electrical happenings, the only thing I can rationalize is, the entities that are here, are able to use the electronics/electrical connections to let us know they're around.
My theory is, entities may not have enough energy to manifest the sounds as we hear them, this may be the reason the sound on the original footage is so much lower than my comparison.

So this video are 2 videos in 1. The original (so you can hear how faint the beeping actually was) and another clip where I physically check the monitor to compare the sounds.

See what you think.
