Need recomendation for IP or wireless night vision security camera(system)

As the title says, I need some help on finding a good camera that will operate at least 500 to 600 feet back to the house.

We have been having problems with prowlers after dark here for the last couple of weeks.

A few nights ago someone tapped on the window and then would not respond when I went to the door.
After a couple of times trying to get an answer, I fired a couple of warning rounds from my 40 into the air.

Our home is 850 feet from the road with no line of site to the road.

I have a solar powered driveway alarm in mind to purchase.

I would also like to put at least a four camera system in place.

Thanks for any help,

Herb
