To address the hazard of passenger head impact with cameras that are mounted in school buses and protrude several inches from the ceiling, REI introduced a low-profile, recessed camera that only extends 1 inch from the ceiling and creates a safe passenger zone, company officials said. Other features of the camera include adjustable viewing angles, high-resolution color and intelligent IR technology designed for viewing footage clearly day or night. A tamper-proof design allows for maximum safety and accountability of drivers and passengers, according to the company. The camera can be mounted in a variety of locations throughout a bus. Two lens sizes are available: 2.8mm and 3.6mm.
