Raising the Bar with High-Performing Video Conferencing
Seeing is Believing
In designing our conference cameras, and the lenses in particular, we start with the premise that the cameras will be used in a wide variety of lighting conditions. In every instance, they need the fluidity, sharpness, and color rendition that are critical to natural, life-like video.
To achieve our own demanding specifications, we decided to design the optics for Rally Bar and Rally Bar Mini ourselves. We also knew that doing so required the mastery of several engineering disciplines: optical, electrical, and mechanical. As part of this design process, we test our cameras and lenses in a simulated meeting room environment where we can account for a wide range of lighting conditions.
Unlike typical video bars that rely on a fixed lens that can only “pan” or “tilt” when zoomed in, both Rally Bar and Rally Bar Mini feature smooth motorized lenses that deliver expansive room coverage at every zoom level. For example, to capture notes on a whiteboard, you can easily zoom out and pan over. By aiming the lens at the subject, Rally Bar and Rally Bar Mini deliver video quality that fixed-lens systems can’t match.
“Because we have control over the manufacturing process, we can make sure our cameras work flawlessly in any room and lighting situation – morning, midday, evening; with sunlight, without sunlight,” says Bryan Loh, Senior Manager of Imaging Engineering at Logitech.
More Than Meets the Eye
In the meeting room, conference cameras should do more than just capture audio and video. Artificial intelligence and advanced software play an increasingly important role in the images and voices broadcast to remote participants.
Rally Plus, Rally Bar and Rally Bar Mini, Logitech’s premier conference cameras for every size meeting room in your organization, include a number of software innovations that enhance the benefits of their precision optics. These include:
RightSight™: Finds human silhouettes within the camera’s field of view and automatically pans, tilts, and zooms to comfortably frame everyone in the meeting
RightLight™: Optimizes light balance and color to prioritize the appearance of faces and render natural-looking skin tones, even in dim or backlit conditions
RightSound: Improves voice clarity by suppressing background noise and echo, auto-leveling voices, and focusing on the active talker so that everyone can be heard
AI Viewfinder is another innovation designed to improve the visual experience for meeting attendees. This second built-in camera helps optimize RightSight, which uses it to automatically adjust and reframe the image. AI Viewfinder informs the camera when people step in and out of the room or out of sight of the main camera, so the camera can then zoom in or out pan as needed to bring everyone back into focus.
All Together Now
The video bar is a novel approach to video conferencing hardware. On one hand, it simplifies the experience for meeting participants and IT professionals. On the other hand, a video bar makes the work of audio and video engineers just a bit more complicated.
Not only does a video bar have to produce great audio and video, but it must not allow either element to interfere with the other. Motorized movement in the camera must not be picked up by the adjacent mics. And speaker vibration must not cause shaking in the camera.
At Logitech, our engineers love a good challenge. In designing Rally Bar and Rally Bar Mini, they created a highly sophisticated conference camera that works hard to make the meeting experience feel as comfortable as being there in person.
