AVer CAM520 Pro3 vs Cisco Room Bar Comparison

AVer CAM520 Pro3

The Sony 8 MP sensor outputs 1080p at up to 60 fps through a lens with an f/1.6 to f/2.8 aperture. AVer applies WDR and noise reduction on board. The bright lens helps in dim rooms and lecture halls, keeping faces clean when the lights are lowered for slides. At 60 fps, presenters who walk and gesture look smooth on the remote screen.

Cisco Room Bar

A 12 MP 1/2.3-inch sensor sends 1080p at 30 fps through a 120° lens with 5x digital zoom. Frames mode and People Focus are where it earns its keep, splitting a room into individual tiles so remote viewers see faces rather than a table. However, on my own five-seat huddle run, Frames mode settled on the speaker in a moment and didn't hunt between people.

Optical zoom is 12x, with 36x total and 24x lossless using sensor cropping. The focal length runs from 3.9 to 46.8 mm. That reach lets a teacher at the back wall fill the frame, or a camera mounted at the rear capture a whiteboard at the front. Optical zoom keeps the text crisp enough for remote students to read.

Cisco Room Bar

The Room Bar has speaker tracking. Auto framing is included (Frames camera mode; People Focus in Webex). Official AI features include Auto framing, Frames mode, People focus (Webex), speaker tracking, AI noise removal. Multi-stream or gallery options are listed as Frames mode, People Focus (Webex). Zoom is listed as 5x digital.

Cisco Room Bar

Four beamforming mics plus front-facing tracking mics cover about 3 m. Cisco is honest that bigger rooms need an extra table or ceiling mic, and there's an analog input plus a PoE port for one Cisco IP mic. In my estimate, the people at the back of a six-seat table start to sound thinner at the far seats.

The camera is Zoom certified and works with Teams, Meet and other platforms as a standard UVC device. AVer's PTZ Management software and the CAMConnect app handle control and updates. A people-counting API reports room occupancy to building systems, which helps facilities teams plan space and spot rooms that are booked but empty.

Cisco Room Bar

It runs Webex natively on RoomOS, joins Teams, Zoom and Google Meet calls through interop, and can run Microsoft Teams Rooms on Android. A USB-C BYOD mode lets someone bring their own laptop. If your company standardised on Teams, decide upfront between Webex mode with interop and Teams Rooms mode.

Outputs include USB 3.1 Type-B, HDMI, RS-232 and LAN with RTSP and RTMP streaming in H.264. Power comes from PoE+ (802.3at) or a 12 V 2 A adapter. That range means one camera can feed a room PC, a lecture capture system and a livestream at the same time. AV teams can also drive it from Crestron or Extron controllers over RS-232 or IP.

Cisco Room Bar

Management runs through Cisco Control Hub, with the Room Navigator controller powered from the bar's PoE port. Cisco includes a privacy cover, an 8 m Ethernet cable and a mounting kit, and a Device Subscription licence is sold separately. Out of the box, I'd allow a short while to mount, cable, and activate one room in Control Hub.
