The Barcelona circuit has added a CCTV camera to the exit of Turn 3 - the corner where Fernando Alonso had his pre-season accident - ahead of this weekend's Spanish Grand Prix.
Alonso's crash during testing at the end of February led to wild speculation about what caused it, with McLaren blaming a gust of wind, a theory Alonso himself later dismissed.
The only video made public was amateur footage of the aftermath of the crash.
Now Spanish Grand Prix organisers have added a new camera to the exit of the corner ahead of the race and the test that will take place at the Spanish track next week.
Organisers have also enlarged the openings at Turn 4 to allow better access for tractors.
Other changes include modified kerbs at Turn 9 and a new kerb on the exit to Turn 15.
