Free Video Call / remote PC / presentation / file transfer / movie tracker - all-in-one Software

REMSEM was designed to simulate teaching a class, with the teacher being remotely connected. REMSEM allows to run presentations remotely, take movies of this, create presentation movies offline with high compression, remotely control a computer, and freely transfer encrypted files between any computers. Basic features include bi-directional sound / video / file sharing, clipboard synchronisation and remote desktop access.


Note: REMSEM requires direct access to the remote computer (see below) and provides only for deriving connection details an IP-username service.

How REMSEM connects:

REMSEM requests an identifier like the email address at program start. To connect, retrieve this email from your contact he used and use that when starting to give a talk. REMSEM then retrieves the active IP of the remote computer via a name server and  connects directly to the other machine - no server in-between - all automatically build into REMSEM. 

  • Easy to use,  free, optimized for teaching, working from home, and  presentations

  • No signing up, no server in-between: ENCRYPTED connection: only for retrieving a computer's IP address is a third-party server provided; for convenience only, if wanted

  • Remote office capabilities including ENCRYPTED drag-and-drop file up- and downloading, clipboard synchronisation, full keyboard and mouse support

  • Bi-directional sound / video, unrestricted PowerPoint presentation remotely controlled by the speaker with shared mouse and keyboard

  • REMSEM allows to save a movie or audio of the talk online or offline

  • presentation quality layout without frames and disturbing buttons

  • REMSEM uses only little internet bandwidth and works inter-continentally (15 kilo bytes per second  for the sum of incoming and outgoing data) for the highest image and sound quality (about only twice of a dial-up connection)

  • Automatic detection of audio driver, camera, or DSL-modem and works even without cameras attached and automatically reconnects in case of trouble

Runs on PC of any brand, MacBook Pro with Windows XP (Boot Camp utility)

Firewalls and ports

REMSEM uses several ports of the internet connection. To receive a talk, any firewalls and modems need to be configured allowing these ports (specified in the help files) to accept incoming calls; to give a talk, the firewall needs to let outgoing calls initiated by REMSEM pass through these ports. Companies which usually have very restricted internet and port policies may need to acquire a DSL modem for running the internet separately from the company network and a computer not connected to the company network to safely open these ports for using REMSEM.
