.
All mouse movements and keyboard signals are transferred from the local computer directly to the remote computer over the network
(via LAN
or Internet

(also known as Video Hook Driver) to read the remote screen bypassing Video Display Controller
. Mirror Driver allows to read only changing parts of the screen. The new DirectScreenTransfer technology was implemented in the latest version of Radmin. Developers of the software claim that the adaptation of the new video driver allows Radmin to dramatically increase the rate of screen updates with a minimum utilization of CPU.

However, the folder contents of the installed Client module can be copied and placed on any other folders and/or computers and these computers need not have the Client module installed.
