Poly Studio USB Video Bar

The Poly 842D4AA#ABA is a USB video bar that equips a medium-sized meeting room with clear 4K visuals and room-filling sound. It connects over a single USB-C cable, so anyone can walk in, plug in a laptop, and launch a video call without relying on extra adapters or a complicated setup.

A 120-degree field of view captures people seated at the far edges of the table, while 4K Ultra High Definition resolution keeps shared content and facial expressions sharp. The built-in six-microphone array picks up voices from as far as 15 feet, making it easier for participants at the back of the room to be heard.

Poly NoiseBlockAI and Acoustic Fence technology work together to remove typing noises, hallway chatter, and other distractions. Combined with Hi-Fi stereo speakers, the result is a conversation that sounds as natural as if everyone were in the same room.

The bar carries official certifications for Zoom and Microsoft Teams, so it integrates smoothly with the platforms many businesses already use. Bluetooth and Wi-Fi give you wireless flexibility for device management or quick audio pairing, and a privacy shutter plus a Kensington lock slot provide peace of mind when the system is not in use.

Measuring about 28 inches wide and weighing roughly five pounds, the unit sits neatly below a display in a conference room, a classroom, or a small training space. Whether you are hosting a client presentation, running a brainstorming session, or leading a hybrid lecture, the Poly Studio USB Video Bar helps every participant feel involved and understood.
