Video Conferencing

Video conferencing is a technology that provides simultaneous transmission of video and audio between two or more users using hardware and software communication tools.

Video conferencing is already firmly established in the corporate environment and is used as often as telephony. At the same time, video conferencing has many advantages over phone calls and face-to-face meetings. It allows you to quickly resolve business issues, creates comfortable conditions for communication with colleagues, customers and partners, and also allows you to significantly save the company's money.

What is video conferencing?

In this article, we will consider the organizational issues of the use and implementation of video conferencing in enterprises. Technological aspects related to the use of videoconferencing are covered in this article.

Ways to Implement Video Conferencing

There are three main models for implementing a video conferencing system:

The dedicated solution is fully controlled by the customer and runs on his network.

The cloud solution, where the video conferencing service provider provides the infrastructure from the Internet, and the company uses its terminals (usually a PC).

Hybrid. This method involves the use of both models. For example, a company uses an internal video conferencing system for communication within the company and a cloud service for connecting external subscribers or holding large video conferences when the capabilities or capacity of their system are not enough.

Benefits of video conferencing

Saving time. Video conferencing allows you to meet with remote employees, partners, and clients without leaving the office. No travel time to the meeting place or business trip.

Ease of use. You can make calls and participate in conferences from a workplace or a meeting room using special video conferencing equipment, a computer, or a smartphone.

Scalability. The number of participants is limited only by the capabilities of the video conferencing infrastructure and your needs: you can communicate with one subscriber, a group of participants, or create a webinar that will be seen by thousands of people.

Realism. Video communication conveys much more emotions than a telephone conversation - this is important to establish contact with the interlocutor and resolve business issues. In addition, video communication does not allow distractions and focuses only on communication, as in a face-to-face meeting.

Safety. Modern video conferencing systems allow you to work in closed networks without connecting to the Internet, therefore, provide maximum data transfer security. When connecting to the network, TLS protocols are used, which allow you to securely encrypt information.

Concept of Thin and Thick Client

In computer terminology, the concept of "client" means certain software or hardware that performs the work of interacting with the server in order to obtain data from the user about the actions performed by the system

A thin client is a type of client that can transfer the execution of information processing tasks to a server without using its computing power to implement them. All computing resources of such a client are as limited as possible, it is important that they are enough to start the necessary network software, using, for example, a web interface.

One of the most common examples of this type of client is a PC with a pre-installed web browser that is used to run web programs.

A characteristic feature of thin clients is the use of a terminal mode of operation. In such a situation, the terminal server is used for the process of sending and receiving user information, which is the basic difference from the process of independent processing of information in thick clients.

Thin client advantages:

  • Minimum hardware maintenance;
  • Low risk of malfunction;
  • Minimum technical requirements for hardware equipment.

Negative sides:

  • If the server fails, all connected users will “suffer”;
  • It is not possible to work without an active network connection;
  • When interacting with a large amount of data, the amount of performance of the main server may decrease.
