AVerMedia Live Streamer 311 BO311 Kit review

The AVerMedia Live Streamer 311 (BO311) is a complete streaming kit, not a card-only product. Its package combines the original Live Gamer MINI capture unit (GC311), the Live Streamer CAM 313 webcam (PW313), and the AM310 USB microphone. AVerMedia's US listing identifies the exact package SKU as BO311; the manufacturer technical page and datasheet distinguish the three components. The US product page showed the package as sold out when checked on 2026-10-30, which does not establish what a third-party seller has now or the condition of a used offer.

A separate US manufacturer listing identifies a distinct Live Streamer Duo (BO311D) SKU. Its product-page image labels identify the same GC311 capture unit and PW313 webcam, so this review also covers that shared capture path as a package variant. The BO311D page reviewed here does not provide a detailed box inventory; do not assume that the AM310 microphone from the BO311 package is included. Check the exact BO311D offer, included components and seller photographs separately.

First identify the card inside the kit

The capture unit is the original GC311, not the later GC311G2 StreamLine MINI+. That distinction changes both the computer link and the video path. BO311's GC311 is specified for HDMI 1.4 and Micro USB 2.0 UVC; its maximum recording and display passthrough formats are both 1080p60. The newer GC311G2 instead documents HDMI 2.0 and a USB 3.0 host link, with 1080p60 capture alongside higher-resolution or higher-refresh passthrough modes. Do not use a search result that says only “Live Gamer MINI” to transfer those newer specifications to BO311.

For the original GC311 in BO311, the datasheet's connection diagram shows an HDMI source entering at 1080p60, HDMI output continuing to a display at 1080p60, and USB 2.0 sending video to the PC. This is a useful simple console-to-monitor-to-computer path when Full HD at 60 frames per second is enough. It is not a 4K recording option, and the HDMI 1.4 connection does not promise HDR or high-refresh passthrough. AVerMedia's GC311 datasheet also excludes HDCP-protected video; protected streaming-video sources should not be treated as capturable.

The USB 2.0 link is a real boundary

USB 2.0 is not merely the connector shape. The manufacturer calls out a Micro USB 2.0 UVC capture connection, so this package does not meet a requirement for an external USB 3.0-or-faster card. The box specification lists a USB cable with the capture unit, but it does not turn the host path into USB 3.0. If your workflow depends on a specific USB generation, avoid assuming that an adapter, hub, or cable can raise the device's native link capability.

The separately included PW313 webcam and AM310 microphone may make the kit practical for someone assembling a basic desk setup from scratch. AVerMedia's package page names the three units, and the datasheet lists component accessories and separate USB connections. But bundled extras are only useful if they fit the actual setup: a buyer who already owns a camera and microphone may prefer a card-only model rather than paying for duplicative peripherals. This is one reason to assess BO311 as a kit instead of describing it as interchangeable with a GC311-only purchase.

OBS is documented for Windows, with a legacy-software caveat

AVerMedia publishes a Windows OBS setup that adds GC311 and PW313 as video sources and describes audio-device selection and monitoring. That provides a named Windows/OBS path for the capture components. The BO311 specification page gives an older Windows 10 requirement for GC311; check the current operating-system, driver and app notes for the computer you will actually use rather than treating a 2019 system-requirement floor as a modern compatibility guarantee.

There is an important software distinction. AVerMedia's support notice says its StreamEngine plugin can cause Streaming Center and OBS to malfunction on Windows 11 24H2, and says StreamEngine is unpublished and will not receive further updates. GC311 is among the named models. That is a warning about the legacy plugin combination, not evidence that every direct UVC capture path fails. Do not rely on StreamEngine as a necessary step; check whether it is installed and follow the manufacturer's current support guidance before planning a Windows 11 workflow.

The BO311 page's dated Mac OS X requirement does not provide a current Mac app and mode matrix, so this assessment does not recommend a Mac/OBS configuration by analogy. The kit's webcam and microphone have their own component specifications and software paths; their presence does not prove that every video, audio or control feature is available in every operating system.

Who should compare BO311—and who should not?

This earlier kit is relevant to someone who specifically wants the named webcam and USB microphone together with a basic HDMI capture path, accepts the original USB 2.0 GC311, and can verify a complete, correctly identified package. It is not a fit for 4K recording, HDR recording, USB 3.0-or-faster capture, or a high-refresh display chain. It also should not be confused with current GC311G2 hardware, whose passthrough figures are materially different.

Before considering any offer, verify the BO311 SKU and the GC311, PW313, and AM310 components; check that the seller's photos and box contents correspond to this kit; and review the return policy, condition, cable set and applicable warranty directly with the seller. AVerMedia's US listing was sold out at the time of research, so this review does not imply that BO311 is available, recommend a price, or promise support for a particular used unit. This assessment is based on manufacturer product and support materials, not hands-on use or performance testing.
