2, however the camera is actually a deadly electro-magentic pulse weapon, it is "extremely dangerous" because when used on cars using Allinol, it causes the fuel to boil, expand and eventually explode and set aflame.
The EMP camera was first seen on the oil rig, being shown to Professor Z. It was also first tested on Rod "Torque" Redline, after being given Allinol. This blew Rod's engine into flames, killing him in the process. Grem and Acer later used it in the Tokyo, Porto Corsa and London races. After the flameout of five cars, race fans thought Allinol was bad and gave up on it, much to the lemon's happiness. The camera was later used on Lightning McQueen, but the pulse failed to work due to Sarge switching out his fuel.
