Do you have a motion light on your house/property?
Do you have any DV or security camera systems? Newer designs like the Night Owl units work outdoors, day or night. You can get a system that works with your iPad/tablet or smartphone too.
They sell them at places like Radio Shack & Sam's Club.
A DV system will help document events if you have a use of force event or if the crooks(s) split you can record a possible description or license tag #.
If you have the $ & time/resources, you may want to think about buying a dog too.
Dogs(larger breeds) can be a great deterrent to burglars & robbers. They can hear much better than humans & will key into any threats. Many convicts & prisoners tell researchers that large dogs are something they worry about more than the LE response or the occupants of a house.
Finally, if you decide to use a home defense shotgun or patrol rifle(7.62 or 5.56mm), Id carry a semi-auto pistol or snub DA only revolver as a BUG/2nd gun.
A crook can snatch your rifle barrel or try to grab your pump shotgun. A well placed .45acp or .40 round can end that story right there,
