Point to Point Wireless Bridging

One of the properties I am responsible for has a 500ft driveway with a big gated entrance.

The owner would like to add a IP security camera at the front gate to catch license plates and faces of those entering the property, with the possibility of more cameras being added there in the near future.

At the other end of the drive, 500ft away, there is a small utility building that houses our firewall, internet connection, etc. I am looking to add a wireless outdoor ready bridge to the building and gate to facilitate the camera install. Does anyone have any any experience with bridging around 500ft? How would you do it?
