Wireless Presentation

Wireless Presentation Buying Guide 2026

Decide quickly – which presentation system is right for you? For small rooms and the easiest start, the EZCast Pro Dongle II is sufficient: an HDMI casting receiver that accepts AirPlay, Miracast, and Google Cast without an app. For the conference room with BYOD, rotating guests, and central management, Kindermann Klick&Show, Barco ClickShare, and BenQ InstaShow lead the field.

Which wireless presentation system is right for which room?

Two axes decide: room size and user group as well as the requirements for management and security. The matrix leads from the affordable entry-level to the managed enterprise system.

Casting, button system, or Wireless HDMI?

Three ways to get the image wirelessly onto the screen, differing in use and convenience:

• Casting (AirPlay, Miracast, Google Cast) uses the device's built-in features – ideal for small rooms and spontaneous sharing. It generally requires that the device and receiver are on the same network.
• Button systems transmit via their own transmitter-receiver pair on their own radio channel, independent of the company network.
• Wireless HDMI (HDMI over radio) transmits exactly one fixed source wirelessly from the HDMI output to the projector – uncompressed and low latency, but without BYOD, an app, or participant switching. Ideal if a PC, media player, or camera is to be permanently connected wirelessly to the projector, for example with the celexon Wireless HDMI Set.

Important for practical use – the internet connection during the presentation:

• Button system: The transmitter communicates directly with the base station, and the laptop retains its existing Wi-Fi or LAN connection. Internet access, cloud applications, and video conferences continue in parallel with the transmission – at the same time, this is a prerequisite for BYOM.
• Casting receiver: If the laptop connects directly to the receiver's hotspot (SoftAP or ad-hoc mode), an internet connection is generally not available during this time. If the receiver, on the other hand, is connected to the existing network, screen transmission and internet access run in parallel.

The most common pitfall in practice: pure casting for conference rooms with many external guests. As soon as the guest Wi-Fi is separated from the company network, casting over the network no longer finds a target. An autonomous button system remains independent and secure for handover here – the reason why button systems are the standard in professional meeting rooms.

Kindermann, Barco, or BenQ – the brands at a glance

All three offer BYOD, 4K, and native casting protocols; simple image sharing is driver- and app-free with all of them. Differences show up in management, conferencing, and integration – and each brand offers a series from entry-level to flagship:

The final selection depends on room size, the number of parallel sources, and your IT landscape; you can find the model details on the respective brand pages. Additional transmitter buttons are available as accessories for all systems if more presenters are to share simultaneously.

BYOM: your own camera and audio in a hybrid meeting

Beyond pure sharing (BYOD), many systems also connect your own laptop wirelessly to the room camera, microphone, and speakers – this is BYOM (Bring Your Own Meeting). This allows you to start a video conference with your own account in Teams, Zoom, Webex, or Google Meet and use the good room technology instead of the laptop webcam.

Important for the selection:

• BenQ InstaShow VS25 solves BYOM purely through hardware: The room camera and room audio appear as standard USB devices on the laptop, which you can select directly in Teams or Zoom – no manufacturer app required.
• Kindermann K-FX Plus and K-FleX (BYOM via license key) use the Klick&Show app under Windows and macOS for BYOM; simple image sharing remains app-free.
• Barco ClickShare CX connects the room peripherals via the button or the ClickShare app.

Important with BYOM: The USB conference camera must be compatible with the respective system – the manufacturers maintain compatibility lists for this. You can find suitable conference room cameras with us; we will clarify which one fits your presentation system during the consultation.

Anyone looking for a fully certified Microsoft Teams Rooms system will find it with Barco ClickShare Hub Core/Hub Pro.

Where is wireless presentation worth it?

• Meetings and conferences: Everyone brings their own device and hands over the screen in seconds – no searching for cables, no adapter ring on the table.
• Education and classrooms: Teachers and learners share screens freely across all operating systems; interactive systems allow whiteboarding and annotations directly on the screen.
• Hybrid teams: A presentation system connects the room image with the web conference, so remote participants see the same content as the room.

In practice, we regularly see that switching from a single receiver to a managed button system is worth it from the second room with guest traffic: IT then updates and monitors all rooms from a single interface instead of each device individually.

If, on the other hand, you are looking for a projector that comes with streaming and screen mirroring out of the box, continue to the Wi-Fi Projector Overview – that is about the projector with built-in radio, here about the system that makes every projector and every display wireless.
