Wireless voting system

Wireless voting system at 2.4 GHz

Voting systems are becoming more and more popular at conferences, general assemblies and smaller meetings. This is because they are a perfect way to quickly visualize audiences position in a given situation. But voting is also increasingly used for events, parties and TV quizzes.

Congress Engineering offers a leading and very user-friendly system called IVS. There are almost no limits on how you can organize your questions to the participants. The system offers many opportunities for visualization of the results and integration with PowerPoint. IVS can be combined with different presentation equipment, including projectors, video walls and monitors.

The NEW Wireless Voting System IVS Lite up to 4000 participants.



The Interactive Voting System IVS® offers the possibility to make a presentation an interactive presentation to get more involvement of your audience. By doing this there is better contact between presenter and listeners. The participant in a meeting can respond to the questions that are posed by the presenter and the presenter can respond to this. In this way interaction is created between presenter and his audience. Instead of listening in a passive way to the presenter the audience turns into active participants.

IVS Lite Keypad



The IVS Lite keypad is a wireless keypad that communicates by means of radio with the receiver.
It is equiped with a simple display that shows the choice that was made. The keypad has 10 keys to cast a vote and is very suitable for every interactive meeting. Identification is possible by means of the number that programmed in the keypad. That also allows use of the keypad for quizzes.
