How to set up the AVer CAM520 Pro3, from unboxing to a working test. It's a USB device: plug it into a laptop or room PC and it shows up as a camera in any meeting app.

Before you start: check the box
- CAM520 Pro3 unit
- Remote control
- USB2.0 type-B to type-A cable (5m)
- Power adapter (3m)
- Wall-mount bracket
- 1/4" tripod screw
- Mini DIN9 to mini DIN8 RS232 adapter
- QR code card
What you need
- Ports on the CAM520 Pro3: Outputs: USB 3.1 Type-B, HDMI 1.4, IP (RJ45).
- For USB mode: a laptop or room PC with a free USB port that matches the included cable. Plug directly into the computer rather than through a hub where possible.
- Power: 12V/2A adapter or PoE+ (802.3at).
Step by step
-
Pick the position. Center the camera on the main display, just above or below the screen, at roughly seated eye level so people look at the camera when they look at the screen. See CAM520 Pro3 mounting and placement.
-
Connect power and cables. Connect the power adapter (or a PoE port, if you'd rather run one cable). Then connect the cables your setup needs (Outputs: USB 3.1 Type-B, HDMI 1.4, IP (RJ45)). Use the cables in the box first; long runs may need the manufacturer's extender.
-
Set up USB mode. AVer USB bars and cameras (VB342 Pro, VB350, VB150, CAM520 Pro3, CAM550, CAM570, VC520 Pro3) and the FONE540 are plug-and-play: connect the included USB cable, open the conferencing software and select the AVer device for video and audio.
-
Update the firmware. The device reboots during the update; keep the power cable connected, since unplugging it can damage the device. See Updating the firmware below.
-
Run a test call. Join a test meeting and check framing from every seat, including whether people at the far end are large enough on screen with zoom and tracking turned on.
Updating the firmware
The device reboots during the update; keep the power cable connected, since unplugging it can damage the device.
