The theory of operation is that since balanced audio has two equivalent signals of opposite phase, a resistor tying hot and cold together […]

LANC Video Camera Control

Camera Control Unit
Camera Control Unit Prototype

This research was undertaken as the final year honours project of a Computer Science BSc. Abstract Due to cumbersome existing solutions, this project aimed to develop a remote video camera control system that imposes minimal hardware overhead to the user. Extensive market research and stakeholder interaction led to the design and realisation of an integrated […]
