I had tried a connected webcam in the past. It seemed that it was triggered by any movement and gave a lot of false positives.
Since my mailbox is connected to IFTTT, it allows me to trigger other things. For instance, I could trigger a Dropcam or Skybell to record video when the box is opened allowing me to see who droped something off or who stole my mail.
