The pre-recording function of the law enforcement recorder means that the system will automatically cache a certain length of footage before the official start of recording to ensure that no critical moments will be missed. Users can set the length of pre-recording according to their needs, ranging from 10 seconds to a maximum of 120 seconds. In this way, even if an unexpected event occurs before the official start of recording, users can still capture important images through the pre-recording function.

Extend Record function means that the system will continue to record a period of time after the end of the video recording. Users can choose 30 seconds or 60 seconds of delayed recording to ensure that even if an important situation occurs after the end of the video recording, it can still be fully recorded.

In real-world application scenarios, the pre-recording and delay recording functions can play an important role. For example, during law enforcement, police officers may face various emergencies, such as sudden violence or traffic accidents. With the pre-recording function, key moments can be captured even in emergencies, providing important clues for subsequent investigations. The Extended Recording function ensures that even if an important event occurs after the end of the video recording, it can still be fully recorded to avoid missing information.

Overall, pre-recording and extended recording functions are excellent in the field of law enforcement recorders, which can improve the comprehensiveness and reliability of the video recording, and provide law enforcement officers with better work support and evidence protection.
