Territorial Reinforcement
Territorial reinforcement uses design and use of sidewalks, landscaping, and porches to create a border between private and public property. These are not meant to prevent anyone from physically entering, but to create a feeling of territoriality and send a message to offenders that the property belongs to someone and they should stay out. This fence is low and will not really prevent anyone from jumping over. But it separates the parking lot from public space. Anyone jumping over would be suspicious. If the fence was not there, a thief could easily walk into the parking lot unnoticed.
A big tall fence with gates will obviously make it difficult for anyone to enter your space without your permission. However, that fence also sends a message saying "This is my property, keep away." Fortunately, it is possible to send the same message without using such extreme structures.
Design Recommendations
Use landscaping as a natural barrier between private and public areas. Use low fences to mark your property. Use different color bricks or different materials for driveways, so as to separate them visually from the street. Landscaping and bushes can be also used to mark territory, but you have to make sure that they do not obstruct the view, or provide hiding spots for offenders.
