The invention relates to a collision recording system, in particular to a collision recording system that records collision data in real time when a collision occurs.

In modern society, car accidents occur endlessly. Most people have encountered major or minor car accidents. Usually, the perpetrators of car accidents will stop and stay on the scene to deal with car accidents. However, there are still some car owners. Worried about punishment and compensation, leaving the scene without regard to the victim's injury, resulting in the victim's loss of immediate medical care, resulting in more serious injuries or death.
