How this score is calculated
Each criterion is the weighted average of its available spec scores (0–10) from our Video Bars & Conference Cameras scoring matrix. Empty specs are skipped, not scored as 0. The Expert Score is the weighted average of the scored criteria, shown out of 10; stars = Expert Score / 20, rounded to the nearest half star. Not scored for this product (it doesn't apply, or the published specs don't cover it): Room Audio Pickup & Output. Its weight is shared by the other criteria.

AVer CAM520 Pro3 Review
AVer announced the CAM520 Pro3 in April 2023 as its first PTZ camera with Smart Composition framing, and it reached shelves later that year. It builds on the long-running CAM520 Pro line popular in classrooms and mid-size rooms.
Optics & Room Coverage 7.6/10
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.
The lack of 4K is noticeable only when you crop heavily or show the feed on large displays. For Teams and Zoom, which usually stream at 1080p, the difference is small.
The diagonal field of view is 80.5 degrees, with 72.8 degrees horizontal and 44.1 degrees vertical. Tilt runs from minus 30 to plus 90 degrees for ceiling and wall placements.
SmartFrame adjusts to the group, Smart Composition frames up to several people into a tidy layout, and Preset Framing jumps to saved positions. Ten presets can be recalled by RS-232 from a room controller.
The wide setting suits medium rooms, though very wide spaces may need the camera mounted further back to fit everyone.
- Optical 12x
- Zoom 12x optical, 36x total
- View 80.5° diagonal
- Room Size Medium rooms and classrooms
AI Speaker Tracking & Framing 9.5/10
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.
The Poly Studio E70 offers a more automated experience, but the AVer gives more zoom flexibility for less money.

OS Platform & Ecosystem 9.5/10
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. That is unusual at this price point.
AVer software works but feels less polished than Logitech Sync or Poly Lens. The three-year warranty is generous compared with one-year cover from many rivals.
- Mgmt Yes (EZManager 2, PTZApp 2)
Deployment & I/O 10.0/10
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.
The body measures 142.7 x 182 x 153 mm and weighs 3.24 lb. A wall or ceiling bracket is sold separately.

The Verdict
I’d choose the CAM520 Pro3 for classrooms and rooms that feed more than one system. If you want simple USB plug-and-play with smarter tracking, look at the Logitech Rally Camera.
