Strange phenomena

This footage cannot be explained, it wasn't captured on purpose and just appeared on the camera of it's own accord. What could it possibly be?

Strange pulsing signal in white noise.

While attempting to capture pure white noise static a signal appeared. Some for of rhythmic pulsing tones. The source still remains a mystery to me. It seems to occur at a regular interval. Very peculiar. 

Over an hour of white noise static for your viewing pleasure.

Remember those old TVs that didn't turn blank/blue/black/silent when you had the antenna not tuned in to a channel?
Don't you miss that?
It was relaxing, soothing and it could help lull you to sleep. Well here is an hour of uninterrupted white noise with the reliable static to accompany it.
Your welcome!
