Product Evaluations

The VTAS advisors carry out unbiased evaluations of ISDN/IP videoconferencing products. The results of the tests and a number of other resources intended to provide assistance to purchasers below.

Note The list of manufacturers represented here is not exhaustive. The presence of a product indicates only that the product has been evaluated by the VTAS product evaluation team and should not be taken as a recommendation. Similarly, the absence of a popular product from the list should not be seen to reflect negatively on that product.

Evaluations of desktop videoconferencing hardware

The USB-connected echo-cancelling loudspeaker/microphone systems in the table below were evaluated and assigned a rating (maximum 35) according to setup procedure, connectivity, echo cancellation, value for money, etc. For a detailed description of the test procedures, please see the overview document

Any one of these systems could be used for small-room video-conferencing applications. The larger more costly systems will provide a better service for larger numbers of attendees and rooms. Differences between the products reflect their cost, and intended purpose. Also, some have slightly better quality of sound reproduction than others. For a more detailed comparison of the products, please see the evaluation document
