The short answer
Outdoor ultrasonic stations such as PetSafe's Outdoor Bark Control react to any barking within range (up to 50 ft), so they will reach a neighbor's dog near your fence. Results vary, many dogs get used to the sound, and other pets can hear it. Talking to your neighbor is usually more effective.

PetSafe Outdoor Bark Control looks like a birdhouse and sounds while barking continues, up to 50 ft. PetSafe Elite Outdoor covers a 180-degree arc. PetSafe notes all dogs respond differently.
