Ruggedized DVR

When you put a Digital Video Recorder in the trunk of a police car, you don't need it to be pretty. You DO need it survive extreme temperatures, moisture, vibrations, and high-speed collisions. The client asked that we accomplish this with an absolute minimum of tooling cost, which means machined housings.

The real challenge turned out to be temperature. The same device that functions perfectly in an Arizona summer must also do so in a Montana winter. Porticos incorporated a heating element and convective cooling system that JPS programmers were able to control based on the ambient temperature. Thermal FEA (Finite Element Analysis) allowed us to find the "hot spots" and make sure we could conduct the heat away from sensitive components.
