The coverage range of each of the five cameras is:

• camera I: $\frac{1}{5}$ of the route;

• camera II: $\frac{3}{10}$ of the route;

• camera III: $\frac{1}{10}$ of the route;

• camera IV: $\frac{1}{10}$ of the route;

• camera V: $\frac{3}{10}$ of the route.

At a certain time, bus A departs from terminal 1 and covers the total route at a constant speed of 250 m/min; while bus B, departing from terminal 2, covers the total route at a constant speed of 150 m/min.

Which camera records the moment bus A and bus B meet?
