Buy video conferencing systems online

Video conferencing systems are used in both private and professional environments. With little technology and suitable software, such as Microsoft Teams, Zoom or Google Meet, a spontaneous video call or a planned video conference can be realised. But what is a good video conferencing system and what do you need for a professional video conference?

What do I need for a video conference?

You need a total of four components to conduct a video conference: microphone, loudspeaker, camera and a terminal or display device.

The devices can either be connected individually to the terminal or you can use a video conference all-in-one system. In most cases, combinations of the individual components are already available.

Which microphone do I need - headset or speakerphone?

Many devices already have built-in microphones. Anyone who has had a conversation partner who has set the loudspeaker function on their mobile phone when making a call knows that the voice sounds more metallic and ambient noise arrives much louder. With an external microphone, you guarantee a better sound with your conversation partner.

Which microphone is suitable for a video conference?

Depending on your choice of the perfect microphone, the number of people participating in the call is important. You should also consider where you will often hold a video conference.

If you have your own office or a room where you can work and talk undisturbed, speakerphones are a good choice. If colleagues cannot hear the conversation or you have an unstable workplace, the headset is the better choice.


Headset: The practical combination of headphones and microphone

Headsets are now standard equipment for video calls from the home office. If you are on the road a lot and have to hold video conferences in between, it is more practical to pack only one headset instead of separate headphones and a microphone. In the office, it is also easier to check only one device in case of sound problems.

Why you should wear a headset during a video conference

Nowadays, end devices already have a microphone and loudspeakers built in. But they are not recommended for permanent use in video conferences. If a conversation partner is present without a headset and there is audio overlap, this conversation partner is suppressed and cannot be heard by the other participants in brief moments. Result: The participants without a headset are unconsciously at a disadvantage.

Webcam or PTZ camera: Which conference camera is better?

For occasional video calls, the camera in the laptop is sufficient. But for regular meetings with external partners and clients, it makes a professional impression if you resort to a webcam that renders a high-resolution image, focuses it automatically and blurs the background if necessary.

The biggest difference between the two technologies is that the PTZ (Pan Tilt Zoom) camera automatically 'tracks' the person standing in front of it. This is useful when several people are present at a video conference and each of them is speaking. Then the person speaking is automatically focused. Modern webcams can automatically focus on the person. It is more for video calls with one person.

Which display device can I use to hold a video conference?

The heart of a videoconference is the end device. Whether PC, laptop, tablet or smartphone - you can hold a video conference with all these devices. A smartphone or tablet is sufficient for private video calls. If you hold regular online meetings at work, you will need to use a laptop or PC.

For professional video conferences in the meeting room, you need a display device, such as a projector, display or screen, so that you can see your discussion partner clearly.

A separate camera, loudspeakers/headphones and microphone are necessary so that you can see and understand your conversation partner optimally. With many accessories, it is more convenient to permanently connect these to a terminal with multiple connections.

All-in-one solution: The advantages of video conferencing systems in the conference room

Manufacturers have adapted to the continuing trend of videoconferencing and developed high-quality systems that combine all the important components. These all-in-one systems offer the perfect entry into the world of video conferencing. Depending on the size of the room and the seating arrangement in your meeting room, only a few accessories, such as additional microphones, are necessary.


This is why we recommend an all-in-one system for video conferencing

  • Instead of three devices (speaker, microphone and camera) you only need to connect one
  • Quickly ready for use
  • Cheaper than buying the units separately (models are available from €499.99)
  • Less cable clutter
  • Discreet and modern in the conference room
