Optics & Room Coverage
- AVer CAM520 Pro37.6/10
- Poly Studio X527.7/10Leader
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.
Poly Studio X52
A 20 MP 4K lens with a 110° view, 5x digital zoom and up to 60 fps drives DirectorAI people, group and speaker framing. DirectorAI perimeter ignores people outside the room. However, behind glass walls on my own install, perimeter framing ignored people walking past outside in a moment. That's a real advantage over bars that reframe every time someone walks by.
AI Speaker Tracking & Framing
- AVer CAM520 Pro39.5/10Leader
- Poly Studio X528.4/10
AVer CAM520 Pro3
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.
Poly Studio X52
The Studio X52's official AI features include Poly DirectorAI: people, group and speaker framing, DirectorAI perimeter; NoiseBlockAI; Acoustic Fence. Zoom is listed as 5x digital. Whiteboard handling is listed as Digital whiteboarding. In rooms I've set up, I care whether tracking stays with the speaker without hunting around the table.
Room Audio Pickup & Output
- AVer CAM520 Pro3—
- Poly Studio X528.7/10
Poly Studio X52
Four mics, two MEMS and two second-order, reach about 6.09 m, and an optional expansion mic plugs into the line input. I'd expect clear pickup across a typical medium room, enough for most medium rooms of six to nine people without extra mics. Mixing MEMS and second-order mics at about 6.09 m is why the X52 covers medium tables better than the X32.
OS Platform & Ecosystem
- AVer CAM520 Pro39.5/10
- Poly Studio X529.9/10Leader
AVer CAM520 Pro3
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.
Poly Studio X52
Teams Rooms, Zoom Rooms and Google Meet run in appliance mode. For legacy endpoints there's Poly Video mode with SIP and H.323, plus a USB mode for guests. It's certified for Microsoft Teams, Zoom and Google Meet, and a TC8 or TC10 touch controller sits on the table. Enroll in Poly Lens on day one so monitoring isn't a later project.
Deployment & I/O
- AVer CAM520 Pro310.0/10Leader
- Poly Studio X529.2/10
AVer CAM520 Pro3
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.
Poly Studio X52
Poly Lens manages firmware and settings remotely. The box includes a monitor clamp, power adapter and cables. I'd allow a short while for mounting, cabling and pairing the TC10. Monitor clamp and power accessories in the box get a pilot room live quickly; production rooms still need planned cable paths.
