Marshall Electronics debuts the CV620-TBI PTZ camera at the 2022 IBC Show (Stand 11.C23). Designed to auto-track and follow presenters using more natural Pan/Tilt/Zoom movement methods with AI accuracy, the CV620-TBI uses new facial recognition technology and intelligently learns motion dynamics of the subject and anticipates movement. This removes much of the guess work for camera intelligence reducing late or inaccurate manoeuvres that require corrective adjustment, greatly minimising viewer fatigue and motion sickness.
The CV620-TBI (black) and CV620-TWI (white) PTZ cameras are built around new highly sensitive Sony sensor technology with 20x optical zoom range of 5~110mm starting at roughly 60° angle-of-view. The CV620-TBI delivers outstanding colour reproduction with exceptional detail even in challenging light environments. These new PTZ cameras feature simultaneous HD outputs of 3GSDI, HDMI and IP ethernet connectivity with up to 1920x1080p resolution at 60fps. Also boasting a flexible 340° horizontal range of movement and 120° vertical tilt, the CV620-TBI provides a large reachable viewing area for the new auto-tracking feature.
Track and follow technology is not new to the PTZ camera market. Early versions required a secondary fixed camera usually installed into the base of the camera to scan the environment and required a lanyard to be worn by the speaker. Viewers of content of these early auto-tracking cameras had to deal with viewer motion sickness and fatigue. As auto-tracking features have been refined over the years, these elements have been removed and much smoother manoeuvres with greater accuracy have been implemented.
“Marshall has been waiting for AI technology to advance enough to integrate it into auto-tracking cameras, and deliver smooth accurate positioning without causing viewer fatigue,” says Tod Musgrave, Director of Cameras for Marshall. “The CV620-TBI now offers that level of performance without requiring lanyards, extra software or a secondary reference camera.”
The new CV620-TBI track and follow cameras are equipped for local AV production workflows with 3GSDI and HDMI outputs, as well as a remote AV over IP camera source. Ethernet (IP) connectivity offers ease-of-setup and operation with one cable for PoE+, video, audio, tally and control.
Marshall dedicates considerable resources to ensure its cameras are compatible and controllable from common soft codecs such as OBS project, vMix and other software production tools. Control can be sent from the included IR remote or a Marshall VS-PTC-IP broadcast-style controller, VS-PTC-200 entry level controller, Video Management Software (VMS), software GUI from a web browser, as well as third party control decks, such as Skaarhoj and others.
Marshall also collaborates with companies like Netgear to enhance ease of configuration with managed switches specifically engineered for AV over IP. Marshall cameras are selectable within the Netgear M4250 and M4300-series switches to allow for quick setup and configuration.
