Community sites

Perhaps industrial sites which are more like a community than individually owned areas would help to convey a move substantial sense of ownership.

The use of a combination of research theories could cultivate much more controlled environments instead of the current fenced off plots of land which tend to create areas of segregation.

Also, should these areas be declared as private property? Surely declaring the space as public creates the chance of encounter.

Protection - Detection - Response

A trap which works with multiple triggers would improve detection and could help to establish a much better response.
A fly trap works by using small hairs on the inside open surface.
First a fly lands on the this surface and hits a single hair, which alerts the plant to its presence, and then the time between the fly triggering a second and third hair establishes how quickly the fly is moving and dictates how quickly the trap closes.

A great example of biomimicry then if . . .
Trigger 1 alerts the owner to the presence of someone on the property
Trigger 2 alerts the authorities
Trigger 3 alerts the intruder that he has tripped an alarm, by which time the response is already in motion.

This is not unlike some of the theories put forwards by Bruce Schneier, who talks about security as a triangle which relies upon the next side in order to function effectively.

Protection - Detection - Response

Man Trap

The original box trap ?

Is simple security the answer?

Home Alone

Perhaps the answer to security lays in the everyday? Using what's around you in order to secure what is rightfully yours.

However there would be some legal issues surrounding home-grown security products so this is probably one avenue I won't explore further.

Semiotics

Semiotics, also called semiotic studies or semiology, is the study of sign processes (semiosis), or signification and communication, signs and symbols, and is usually divided into three branches:
Semantics: Relation between signs and the things to which they refer; their denotata
Syntactics: Relations among signs in formal structures
Pragmatics: Relation between signs and their effects on those (people) who use them.

These factors tie in well with some of the theories I have read through as part of my research and help to make clear the meanings that people can obtain from objects, which is what some of the concepts are intended to portray

Sight

Red lines which travel the length of the business park act as boundary with open areas highlighting entry points.

Sight

Generic signs for each business within the same industrial estate create a sense of unity.
