Usage Details
- Monitors can show themselves through the camera, but you should avoid abusing this feature, because it affects performance.
- Note that a black-and-white monitor will display colour video in fullscreen mode.
- The surveillance camera can be switched in-game using trigger_changetarget. A monitor shines in the dark when it is on and does not shine when it is off.
- Monitors should be assigned a special kind of texture, whose name starts with monitor.
- If video from the monitor is upside down, simply turn the texture around in the map editor.
