Before we get you set up on Classroom make sure that you meet the minimum device system requirements. This document is intended to take you through everything you need to verify on your end, to help ensure that you can run either product effectively on your network and device.

To complete these steps, it is necessary that you have access to the firewall and the content filter. Please contact your Network Administrator or IT organization for assistance. 

Device Client System Requirements

The minimum system requirements for the client are:

2.0 GHz+ Single Core Processor
5GB free disk space
Windows 11, 10 or 8.1 (x64)
Windows Domain Enrollment
Google Chrome
Version 66+
100MB Free Space
Android version 8+
100MB Free Space

For example, most modern laptops or desktop PCs can run the Device Client.Any modern Chromebook device is able to run the Device Client. ChromeOS version 66 was released in April 2018.Any modern Android device is able to run the Device Client. Android 8 was released on August 21, 2017.

Network Access Requirements

It is necessary that the following addresses and ports, depending on region, are allowed in your firewall or security application. By doing this helps ensure that the client can connect safely and securely to the server and users can authenticate into the application.

Web App

The Web App is the front-end interface that the Teachers use with their Students. Whitelisting the below URLs allows the application to connect to the server and be functional.

  • TCP port 443
  • TCP port 443
  • TCP port 443
  • TCP port 443

(It is necessary that both HTTPS and Secure Websocket connections are allowed)

Device Clients

The Device Client uses the below URLs to communicate with the Web App over the Internet and therefore being able to use the application.

  •    TCP port 443
  • api.$   TCP port 443(Make sure to replace the $cluster with the regional zone, i.e.,
  • *
  • * TCP/UDP   port 80, 443, 1024-65535**

If your Web content filtering does not accept wildcard entries, you can find a list of the specific URLs and IP addresses for the services. 


**The Impero Classroom utilizes webRTC technology to provide the live view from devices in the web browser. webRTC uses TCP/UDP ports in the following range: 1024-65535.
In most cases, there is no need to open ports as networks allow for these types of communications without additional configuration.

Whitelist the below URLs depending on your region.  These URLs help ensure that the app connects to the region that you are based in.

Australia (AU)

Canada (CA)

Europe (EU)

United Arab Emirates (UAE)

United Kingdom (UK)

United States (US)

The following environments are used for demonstration and testing purposes only:
