Mysterious Apparition Caught On Video

The original description was the folks who submitted the video reads: 

I was having breakfast with my family. At about 10:30 am, my dog started barking and ran to the front door. I was waiting for a courier delivery and I figured it was the driver dropping off the parcel. I went to my front door and looked out the window and no one was there. Then I received a notification on my cell phone the motion sensor on my door bell was was activated. My first thought was that the delivery had arrived, so I opened the door and went outside to retrieve my package. Nothing was there, so I walked down my walkway but nothing was there. This is when I decided to log into my alarm account and see what triggered the motion sensor. As I was watching the video, I saw a translucent image floating across the screen. I had many thoughts running through my mind at that moment, mostly confused. I played the video over and over. My family looked at it too, they were puzzled. This was when I took it to social media. I posted my video and asked my friends and family 'what do you think?'. Since then, I have seen so many theories and explanations. From guardian angels, spirits, bugs, raccoons, leaves, plastic bags, shadows, everything. One psychic who viewed the video told me the bench located on the bottom right corner of the frame had a connection to this translucent image. That bench was given to me by a very dear friend just before he died. The last conversation we had was on that bench, just the two of us. I would like everyone to see this video and see for themselves what they think. It's amazing how many different perspectives there can be from a 30-second video.
