Abstract

A rear-view mirror and modular monitor system and method include an interior mirror that embeds a modular monitor behind see-through mirror glass. In some embodiments, the system includes multiple cameras, some in the vehicle, bus and/or truck, as well as some cameras outside the vehicle, bus and/or truck, advantageously providing the driver an opportunity to view what is happening, for example, in the back rows of the bus and/or cabin, while also using the mirror to look at objects in the bus and/or cabin that are visible using the mirror. The rear-view mirror and modular monitor system is configured to be easily assembled and/or disassembled when necessary for maintenance and/or to replace parts.
