It's pretty cool once you get used to how it works. To start, simply enter a property address at the top to search. When that specific property's area map opens, you can adjust the criteria by using the tabs above the map for crime types, dates, etc. The date will only go back for the past six months, but if you use the same criteria consistently it will give you a great idea of how much relative crime there is within a certain radius of a given address. 

 

I like to search by zip codes myself. You can plug in the address as "89123, Las Vegas, NV" and pull up everything within a mile radius. Here is a zip code map you can use as well as links to homes for sale within each zip code.
