Car DVR replacement and related shenanigans - part 2

Moving along with more details, like I mentioned in the previous post, the rear camera was reused from the previous installation. This CCD based camera happens to be superior to the basic CMOS camera bundled with the kit. Both in terms of the quality of the sensor itself and its low light sensitivity, but also regarding the lens, featuring a wider viewing angle (important given its role as a backup camera).

The only change however was a substantial improvement in the mounting design, by having added an U-shaped plate in the rear of the camera, with a 4-screw mount instead of the original 2 screws attached to the sides of the camera. This provides a more solid attachment to the L-shaped aluminium parts that in turn stick to the door through an adhesive:

4-wheel adventures ranging from customer relationship to automotive hacking

1. Context

Since more than a decade ago, automotive technology have captured my interest to some extent. Not so much in the mechanical domain, for which the industry have in most part been over the years conservative and slow in pushing inovation, but mostly in respect to the digital framework that integrates the vehicles. This overlay of digital technology plays a fundamental role in modern cars, ranging from safety, fuel economy, controlling the production cost (by reducing the number of individual parts), emissions control, comfort and entertainment.

The meanders of OBD-II protocols

As we travel through the history of automotive technology back and forth, we realize that at the heart of the machines that enable us to go from point A to point B faster than our legs, are a number of components that essentially haven't changed too much: engines still burn fossil fuels and the vast majority are based on pistons that transform the explosive energy of the fuel combustion into movement.
