A hard perimeter consists of materials and equipment that provide the level of security and safety necessary for the event. This can consist of concrete barricades, secure vehicle access points, fencing, metal detectors, and heavy equipment among other resources. The hard perimeter closes off both pedestrian and vehicular traffic inside the restricted area unless the individual and/or vehicle have the appropriate credentials to gain access.

The devices used to define a soft perimeter vary. Because the perimeter is soft, it does not limit access the same as the hard perimeter. As such, the soft perimeter may use standard traffic control devices in conjunction with law enforcement support to control access. For the G-20 Summit, the soft perimeter allowed pedestrian traffic as well as public transportation(i. e., buses, taxis, and functional needs transportation services) to enter through checkpoints.

CONT

An anti-bird roosting device for protecting an area, comprising at least a pair of cooperating base elements mounted on the area to be protected, and a plurality of projecting spikes, supported on the base elements and projecting away therefrom into a space above the area to be protected. The spikes are provided in a pattern of interspersed combinations of vertical, obtuse and acute angle-forming projections, in a high spike density that prevents roosting in the protected space. Thus, each point in the area to be protected is defended by more than one spike, each spike coming from a different direction, so as to cross-defend each other, creating a perimeter envelope defense of the air volume surrounding the base elements. Each device is easily and inexpensively prepared as a continuous mesh, whose dimensions can be constructed in standard sizes or in accordance with the needs of the user. The element diameter is typically approximately two millimeters. The small element diameter makes the entire device hard to see from a distance so that it does not detract from the building's aesthetics.

CONT

Porcupine wire, typically marketed as Nixalite, prevents birds from perching and roosting on flat surfaces such as ledges and signs. ... Nixalite is a system of stainless steel strips that feature needle-like wire prongs. The prongs project from a 0.5 centimetre base and come in two lengths - 5 and 9.5 centimetres. Strips are available in either single (90°) or double (180°) radius.
