5 basic components of a Virtual Classroom – Explained

The full HD PTZ camera

A PTZ camera is a camera with pan, tilt and zoom functionalities. The camera head can be moved on an axis vertically and horizontally to shift the focus of the camera quickly and remotely. This is for the above reason such PTZ cameras are also called robotic cameras. These cameras are commonly popular in virtual classroom setups. Since a classroom session includes several views of a classroom to be captured and duplicated at a remote place. PTZ cameras can be used in Virtual Classrooms to capture almost entire view of the classroom by moving the camera head to different directions. A high definition PTZ camera is considered ideal of a virtual classroom, since it requires the tiniest details on the blackboard to be captured with clarity.


A microphone is an essential part of a virtual classroom setup. It enables classroom audio to capture. A wired microphone can be considered more reliable as compared to a wireless one. However, if the teacher wants to move within the classroom while teaching one can also use a wireless microphone with omnidirectional audio capture capacity. At the same time, a microphone also serves the purpose of a virtual classroom of two-way communication. An audio-based two-way communication is considered to be prompt and engaging as compared to a web chat.

Speakerphone for backup

There are situations in a virtual classroom when the internet connection goes slow and it becomes difficult to properly communicate between the studio and a remote classroom. In cases where wireless microphone become unstable and there are issues with the transmitter and receiver connectivity. In such a failure of audio components in a virtual class it is necessary to have a backup audio device for two-way communication. A speakerphone is a device which consists of audio capture and output on a single unit. This unit can be connected to a PC via USB or a wireless connection. The device can be used as a traditional telephone to communicated both sides with the help of virtual classroom software.

Digital Signal Processor

In a studio type virtual classroom, the audio setup is compact and squeezed into a small room. In such a setup the microphones into a virtual classroom start retrieving feedback or echo from the closely kept speakers. This creates a continuous echo in a virtual classroom setup. To avoid this, echo a digitally programmed device call digital signal processor or more precisely audio signal processor is used to give digital feeds to a virtual classroom system. The device is highly sophisticated and precise in canceling this echo to be transmitted from one place to another for a disturbance-free two-way audio communication.

Media Collaboration Software

A virtual classroom setup enables the instructor to capture and transmit classroom sessions to a remote location through a computer operated virtual classroom setup. In today’s world of digital media and access to international content through world wide web, it has been an easy process for the teachers to store and transmit data instead of just chalk and board learning. To help this purpose virtual classroom setups are nowadays incorporation a media collaboration software which manages the classroom capture as well all digital media to be shared between classrooms. A media collaboration software is nothing but a so-called virtual classroom software which manages the digital content to be transmitted from a classroom to another.
