Our take
The original AVer CAM340 is a room-oriented camera with 4K25, lower-resolution modes through 1080p60, a 94-degree diagonal view, privacy shutter and one built-in microphone. Its fixed lens and USB 3.0 requirement for 4K or 60 fps are decisive setup limits, and the historical Amazon ASIN is not linked to the model.
A small huddle room that needs a wide documented 4K25 camera, a physical shutter and optional 1080p60 operation over a USB 3.0 host connection..
Not for buyers who need 4K30/60, autofocus, unpowered USB 2.0 use at 4K or 60 fps, confirmed current host software support, or proof that ASIN B071W8VLKS is the original CAM340 package.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- AVer lists 3840×2160 at 25 fps plus 1080p, 720p and other lower modes at up to 60 fps.
- The 94-degree diagonal field, physical shutter and one built-in microphone are documented.
- USB Type-C, UVC 1.1/UAC 1.0 and a tripod screw or built-in TV mount are listed.
What to weigh up
- The lens is fixed; 4× digital framing through the 4K sensor is unavailable at 4K and 60 fps.
- USB 3.0 is required for 4K or 60 fps; USB 2.0 use requires the included power adapter.
- This original CAM340 must not be confused with CAM340+, and the historical candidate ASIN is unverified.
Specifications and exact model details
The key details
| Model covered | CAM340 |
|---|---|
| Documented video modes | The AVer datasheet lists 4K at 25 fps and multiple lower modes through 1080p60; 4K25 and 1080p60 are different modes. |
| Focus and framing | The lens is fixed; the camera provides a 94-degree diagonal field and up to 4× sensor-crop framing, unavailable at 4K or 60 fps. |
| Light and lens privacy | A privacy shutter is documented; a visible fill lamp and shutter-linked audio cutoff are not confirmed. |
| Integrated audio | One unidirectional built-in microphone is documented; pickup quality in a particular room is not measured. |
| Connection and mounting | USB Type-C with UVC 1.1/UAC 1.0 is documented; the manufacturer requires USB 3.0 for 4K or 60 fps. |
| Identity and setup limits | CAM340 is distinct from CAM340+; the historical ASIN and the exact package are not cross-mapped to the original model. |

Full review: how the features affect your choice
What the features mean for you
Original CAM340 identity and dated documentation
AVer maintains an [official CAM340 model page](https://communication.aver.com/model/cam340) with links to its brochure and datasheet. The specification documents date to 2017, so they are useful for stable hardware attributes but not a current software-support guarantee. The saved candidate record's raw part hint says COMSCA340, while historical ASIN B071W8VLKS could not be tied to an exact package. This review identifies the manufacturer model as CAM340 and does not add that ASIN as a direct link. AVer's CAM340+ is a different product page and part family; no specification should be transferred between them. Use the tagged CAM340 search and check the exact model marking and included accessories.
4K25 and 1080p60 are separate operating modes
The manufacturer datasheet lists 3840×2160 at 25 frames per second. It separately lists 1080p, 720p and several smaller output sizes at 60, 30 or 15 fps. That supports both a 4K video mode and 1080p60, but it does not mean the camera captures 4K60. AVer states that 4K or 60 fps requires a USB 3.0 port and a higher system configuration. This distinction matters for someone planning smooth motion: select 1080p60 when rate matters, or 4K25 when detail matters, and confirm the host meets the connection requirement. The review does not infer image quality or latency from pixel count.
Fixed lens, wide room view and digital framing limits
AVer specifies a fixed lens and gives 94 degrees diagonal, 85 horizontal and 55 vertical field of view. It also describes up to 4× reframing by using the 4K sensor, with digital pan and tilt while zoomed. The same datasheet explicitly says that this function is unavailable in 4K and 60 fps. That makes the CAM340 more adjustable at lower output settings than a simple fixed webcam, but not a mechanical PTZ or autofocus camera. AVer lists the system as fixed focus and fixed zoom; the profile therefore does not award autofocus. The minimum working distance is 80 cm, a useful placement check for a camera intended to cover people around a huddle table.
Physical privacy and built-in audio
The datasheet lists a privacy shutter door and one unidirectional microphone with a published frequency response. That is a simpler audio arrangement than a beamforming array or a separate room speakerphone, and the materials do not establish how far a voice will carry in a particular room. A shutter physically covers the lens, but the source does not say that it electrically mutes the microphone when closed. A visible illumination lamp and built-in loudspeaker are not listed, so those remain unknown for matching. If the room already has a speakerphone, the CAM340 can provide the camera function; if not, plan separate output audio rather than assuming the camera contains a speaker.
USB connection, package and room installation
AVer identifies a USB Type-C connector, UVC 1.1, UAC 1.0 and YUV/MJPEG video. The 2017 package list names a 6-foot Type-C-to-Type-A cable, Type-A-to-Type-C adapter, a power adapter for USB 2.0 use and a quick guide. The datasheet also lists a built-in TV mount, a quarter-inch tripod socket and a Kensington slot; wall mount and remote are optional accessories. Because the candidate Amazon offer is not mapped, those contents describe the maker's original product package, not a verified current seller bundle. Compatibility entries refer to older Windows, macOS and Chromebook versions. Confirm current computer, app and support needs before buying a legacy camera.
Compare for your needs
For a personal desk setup with a current compact 4K webcam, compare Logitech Brio 4K Pro. For a conference camera that can be moved by a room operator, compare Tenveo TEVO-VHD1080Pro; its published angle is horizontal and its focus details conflict.

Before you buy
Does CAM340 support 4K at 60 fps?
No. AVer lists 4K at 25 fps and lower modes, including 1080p at up to 60 fps.
What port is required for 4K or 60 fps?
AVer's datasheet specifies USB 3.0 for 4K or 60 fps; USB 2.0 usage requires the listed power adapter.
Is the CAM340 lens autofocus?
The original CAM340 datasheet describes a fixed lens and fixed focus; it does not list autofocus.
Is CAM340 the same as CAM340+?
No. AVer publishes separate model pages and documentation. This review covers original CAM340 only.
Is ASIN B071W8VLKS verified as original CAM340?
No. The saved candidate-page check did not establish the model or package match; use the tagged exact-model search.
Where can I check the current price?

The decision
Choose original CAM340 when its 4K25 mode, 1080p60 option, wide fixed field and physical shutter suit a huddle room with USB 3.0. Check the exact package, host and product identity before ordering; do not substitute CAM340+ details or the unverified historical ASIN.
