Knowledge Base - FAQ
How do you manually focus an FVA-2400?
While the image is live, hold the [CTRL] or [SHIFT] key and move the mouse to the left or the right. To achieve optimal focus, first begin moving the mouse to the left until the image focuses or you reach the end of the travel. If you reach the end of the travel without achieving a focused image, move the mouse to the right until the image comes into focus.
