Add camera rooms with live computer footage instead of having to open a terminal.
Examples:

• Central observation room/area in an atrium with camera footage on computers/screens.
• Camera room in the command center of the mountain base.

You could either make it where the camera's have to be placed by GnR/EnL or standardly place them around the map. When a camera breaks, it appears as a broken signal on the respective computer screen and has to be repaired by E&L.

The best but most complex system would be where G&R can place the camera's anywhere. They'd be able to connect their camera to a computer screen in the area where the live footage will be transmitted to.
E.g. G&R places camera watching a pond within an atrium and connects it to one of the computer screens of the atrium's camera/observation room.
