Bluebell Triple Stack Silhouette

Bluebell Opticom at the 2018 NAB Show

At the 2018 NAB Show, Bluebell will demonstrate the Silhouette line of rugged, deployable, high-density, mixed-technology media converters. The heart of the Silhouette power-insertion product family for robotic cameras in remote production scenarios, the Silhouette is a fully integrated 4K UHD robotic head system that works with SD-SDI, HD-SDI, 3G-SDI, and 4K UHD cameras to provide power and control to the camera head and fibre optic connectivity for the remote-control panel. As a result, operators no longer need to rely on stadium power. The customizable Silhouette comes in three sizes and can accommodate any combination of 4K HDR, quad 3G-SDI, trilevel sync, GigE, serial data control, communications, IFB, and multichannel audio signals. Customers can choose to get power from a 12V DC supply, a V-Mount battery, a hybrid cable, or a combination of the three. Introduced at IBC2017, Silhouette units are deployed all over the world in sports, theatre, and music venues.
