All cameras have to be turned on and prepared to start recording a minimum of 75 minutes before the start of the game.

As Figure 2.1 and Figure 2.2 shows, the main camera has to record the center red line during the whole warm-up with a wide focus, so the main part of the neutral zone is recorded. It is not allowed to change the focus or the angle, nor shut off the camera during warm-ups.

Figure 2.1: Position 1 – Camera focus – center line		Figure 2.2: Position 2 – Camera focus – center line

After warm-ups, the camera can be shut off during ice resurfacing after the last player has left the ice.
