Background
Porticos provided technical expertise and program management for Integrian, whose A/V ensemble had to meet rigorous physical demands and accommodate end-product branding. We designed all components of the end product, including the main DVR unit, police car-mounted wireless receiver, officer-worn wireless microphone and belt clip, and a single- and multi-slot charge dock for the wireless microphone.
Challenges
To pass the required MIL 810 vibration test, the DVR unit demanded dedicated isolation damping solutions for its 4 internal hard drives. The unit also had to achieve an IP65 rating for water/dust ingress—a requirement complicated by a large number of non-rated connectors (USB, RJ45, SMA, etc.) needed and the need for 4 large fan units.
Porticos solved this challenge by using a “double” seal design in which high-temperature components were thermally conducted to a multitude of cooling fins in the die-cast aluminum frame. Fins were positioned in the fan air stream, while internal electronics were completely sealed from the external environment.
The wireless microphone presented two significant challenges: the required IP rating and the need to accommodate Motorola branding in the end product. To balance these needs, Porticos designed a TPE seal that functioned as both the button interface and the main seal. LED windows required for user feedback were insert-molded to prevent water/dust ingress.
Outcomes
Porticos designed the entire product line and fabricated high-fidelity prototypes for every product. The prototypes cemented a branding deal with Motorola that led to significant additional investment in the company. Porticos supported these products into production and eventual acquisition. We’re pleased to have been part of this entrepreneurial success story.
