Security camera owner says they have never seen anything like this on their cameras - Ever!

This was recorded the same night large bright flashes of light were spotted lighting up the entire sky near San Antonio Texas. This clip was sent to me to analyze and I am simply passing it along. Some say a water droplet but I disagree with that theory because there was no camera blurriness or interference when it appeared, and the particles moving through the air appear to be in front of the anomaly, if it were on the camera lens then it would be pretty obvious that it was in front of the air particles, but that is not the case...looks to be behind. Dunno...Thanks
