Getting robbed is an awful feeling and makes you think that you could have done more to prevent it. Only after, you start to consider that security is more than a simple issue. It is a big one.
Talking security takes more than locking doors and windows when you leave home. There are lots of other things to consider like back and front yard, inside and outside lightning, alarms and safes.
Last summer I lost my laptop and was told by law enforcement officers that I would have to bid on my own laptop at auction unless I could prove the item belonged to me. Luckily my brother in law got me a Ghostprint kit for my birthday and my laptop was one of the first items I marked.
GhostPrint - Secure your Valuables
I hope it will be useful
The officers returned my laptop after providing them with the details of my invisible Ghostprint mark, saving me potentially having to buy my own laptop again!
