The scale of the surveillance window can be adjusted.

This can be done in one of three ways:

1. Using the buttons in the upper right-hand part of the active surveillance window.
2. Using the buttons in the top panel.
3. Using the mouse.

If you click a surveillance window, you can see the size control buttons on the right-hand side. 

1. − increases the size of the surveillance window by one step.

2. − resets the size of the surveillance window.

When a surveillance window is enlarged, the scale of the entire layout is increased. Some of the cells are moved off the screen.

Surveillance windows are enlarged as follows:

1. If a surveillance window occupies 100% of any of the sides of the layout (maximum surveillance window size), it cannot be enlarged.
2. If a surveillance window occupies 50% or more (but not 100%) of any of the sides of the layout, it is enlarged as much as possible.
3. If a surveillance window occupies less than 50% on both sides of the layout, it is enlarged in two steps: the first step enlarges the surveillance window to 50% on the corresponding side of the layout and the second step enlarges the surveillance window to the maximum size.

If a surveillance window is linked to another one or an information board, at the first enlargement step (to 50%), the surveillance window and the other window/information board are displayed together and occupy all of the screen on one side. 

Also, if you click a surveillance window, you can control its size with the buttons on the top panel:

1. − esets the size of the surveillance window.
2. − resizes the window up to 50% on one side of the layout.
3. − maximizes the size of the surveillance window.

How to resize the surveillance window using a mouse:

1. In full screen mode, click anywhere to minimize the window. 
2. Otherwise, double click inside the window to display it in full screen mode.
