Our take
The AnkerWork BR300 A3387 is a USB video conference bar with a camera, integrated speaker and microphones. Its manual lists 4K at 30 fps and 1080p at 60 fps, so it offers more than one documented video-use case. The same manual states a 121-degree field without specifying an axis; the value is not entered as a diagonal field. Amazon B0B4592S5R names BR300 and its A+ images identify A3387, supporting a direct tagged destination. The bar's exact room performance is not tested here.
A small-room or desk conference setup where a USB video bar with integrated playback audio is useful..
Choose another product if you require a known diagonal field, camera autofocus, a confirmed physical lens shutter, or a compact clip-on webcam.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer manual identifies both 4K30 and 1080p60 modes.
- Camera, speaker and microphones are integrated into the video bar.
- The manual's package diagram lists remote, power components, USB cable and wall-mount hardware.
What to weigh up
- The stated 121-degree field has no axis and cannot be used as a diagonal match.
- The checked manual does not settle autofocus or a physical lens cover.
- A video-bar footprint and power adapter require more setup than a simple monitor clip webcam.

Full review: how the features affect your choice
What the features mean for you
Model and exact listing
AnkerWork's A3387 manual identifies the BR300 USB Video Conference Bar. The frozen candidate B0B4592S5R has a current item title naming BR300, while its A+ imagery identifies A3387. Those sources support the direct tagged item route. The model should be kept distinct from other PowerConf and AnkerWork camera bars: the review covers A3387 only. The user manual describes a conference-room product with camera, speaker, microphone, remote and power components rather than a small webcam with only a USB cable. Confirm the box contents for the exact offer and region.
Video modes and field
The manual lists 4K at 30 frames per second and 1080p at 60 frames per second. Those distinct mode/rate pairs make the bar relevant to both high-resolution conferencing and smoother Full HD motion. Its 121-degree field figure appears without an axis, so the product profile leaves maximum diagonal field unknown. Do not compare it numerically with webcams whose makers explicitly label their fields as diagonal. The manual's mode table is a model specification; it does not predict image quality under a buyer's lighting, room distance or software settings.
Integrated room audio
The BR300 places a speaker and microphones alongside the camera. That integrated arrangement can reduce the number of separate desk devices in a small meeting room. The manual describes audio algorithms and remote controls, but those manufacturer descriptions do not substitute for an independent speech or playback test. A buyer should check how the operating system enumerates the bar's sound devices and choose the intended microphone and speaker in the meeting software. The documented product is a video bar with call audio; the review does not claim that it will cover a particular table size or overcome room echo.
Connections, power and mounting
The A3387 manual shows a USB-C-to-USB-A cable, HDMI connection, power adapter and wall-mount bracket. This gives the bar more connection and placement options than a basic clip-on webcam, though buyers must plan for external power and an appropriate display or host connection. The manual does not establish a physical USB-C plug on every included cable end beyond the stated cable, nor does it document Ethernet or Wi-Fi remote viewing. It also does not provide a confirmed autofocus behavior or a physical privacy shutter in the checked material. Leave those fields unknown rather than filling them from marketing images.
Who should compare BR300
Consider the BR300 when an integrated speaker/microphone system and a documented 4K30 or 1080p60 camera mode suit a meeting space. It fits the all-in-one audio category better than a conventional monitor webcam and belongs in the 4K comparison because the manual lists that video mode. It should not be selected on a presumed 121-degree diagonal frame or autofocus feature, neither of which is established here. Compare the included remote, power and mounting pieces with the intended room setup. This review is based on the product manual and model-identifying listing evidence, not on hands-on use, customer reviews or current availability.
Compare for your needs
For an ordinary personal webcam, compare a smaller monitor-mounted model. For a room camera with operator zoom and pan/tilt, compare a documented PTZ camera with a separate audio plan.

Before you buy

The manual lists 4K30 and 1080p60; it does not list 4K60.
Is the 121-degree field diagonal?
The manual does not state the measurement axis, so the diagonal field remains unknown.
Does the bar include a speaker?
Yes. The A3387 manual identifies a speaker as an integrated component.
Is B0B4592S5R mapped to A3387?
The current item names BR300 and its A+ images identify A3387; the direct route is limited to that exact item evidence.
