The present invention discloses a control technology for remote control of security cameras, and more particularly, to a method of providing virtual Joystick environment as if Joystick was used on a computer, and system thereof. A selected region is set on a computer monitor. According to the direction that a cursor is clicked on and dragged within the region, a rotary movement command to pan or tilt a camera at a remote place is generated. If a mouse wheel is rotatably pushed or pulled or the mouse is moved to an additional control region within the selected region, additional functions such as zoom-in/out and focus-in/out are performed. Therefore, the present invention has an effect that a user can feel as if a virtual Joystick was manipulated by controlling movement of cameras in real time as a mouse is moved, while monitoring an image of a subject on a computer monitor.
