Do you own anything worth stealing? If so do you have pictures of these items? How about serial numbers, do you have them recorded anywhere?
I have had clients take a video of each room of their house or business. That way if the place burns down or is flooded out they have a good record to start figuring out replacement costs.
If you have ever gone through the process of making an insurance claim and replacing your possessions you know that the more documentation you have the better.
We are all carrying around a phone that is quite capable of taking good pictures as well as video. Why not make use of this technology?
