PTZ cameras’ many improvements in sensors, lens technology and control have elevated their use to all levels of production from the boardroom to high-end broadcast. A PTZ camera is a pan, tilt, and zoom robotic video camera controllable by a remote operator, which can pan horizontally, tilt vertically and diagonally, and zoom in on a subject to enhance image quality without digital pixilation, writes Abigail Williams in this month's AV Magazine.
"The rise of popular fly on the wall reality programmes, such as Big Brother, heralded a huge shift towards use of PTZ cameras in the broadcast world" says Kim Beard, DigiBox Product Specialist and Account Manager. "AV followed the broadcast lead when the demand for remote technologies driven by the pandemic fuelled a surge in the popularity of PTZ cameras in corporate and enterprise, as well as education. Following the development of NewTek’s NDI (Network Device Interface), the latest generation of NDI PTZ cameras now allows production teams to securely share NDI sources between local or remote sites, anywhere in the world over the public internet. This means that your camera operator, control room or director could be based in another country, operating multiple PTZ cameras in different locations at the same time,” says Beard. With NDI PTZ cameras, Beard says that production teams can also “stay native in end to end NDI workflows, thereby reducing complexity, cost and latency across any distance and with any applications. NewTek’s NDI Bridge delivers local convenience on a global scale as it handles the complexity of offering alpha channel, KVM, tally, and metadata taking the functionality of the PTZ camera to another level. Systems using AVoIPoE also benefit from a reduction in cabling infrastructure required to run PTZ cameras, offering reductions in installation time as well as hardware,” she adds.
