Security managers realize few, if any, devices work well in all environments and are free of false alarms. Most sensors and intrusion motion detectors are susceptible to periodic false alarms. Architects and designers have the greatest control over how secure a building will ultimately be. Decisions concerning pedestrian circulation, access control, building materials, fenestration, along with various other features are determined by architects. But architects, designers, and developers are not the only ones concerned with building security.
Inspectors evaluate building venues for potential security weaknesses.
They also check the adequacy of lighting and the security of doors and windows.
