Porta King's pre-assembled Police Koban, a portable police kiosk, allows law enforcement officials to escape the elements without leaving the streets. Buildings stand 10'6" tall and feature back-lit illuminated signage. Built-in security features include: class III bullet-resistant construction; space to house surveillance equipment; an exterior-mounted autodial "911" telephone for civilian use in case of emergency; and a through-wall climate control, service sink, and dimming lights.
