Vehicle-mounted video monitoring method

Abstract

The invention relates to the field of vehicle-mounted video monitoring methods. A vehicle-mounted video monitoring method relates to a main control unit, an imaging unit, a recording unit, a storage unit and a power supply, wherein the main control unit is connected with the power supply, the imaging unit at least comprises a first imaging unit and a second imaging unit, the first imaging unit is arranged outside a vehicle, and the second imaging unit is arranged in the vehicle; the main control unit is connected with an induction unit and is connected with, controls and synchronously starts up the first imaging unit, the second imaging unit and the recording unit according to induction signals of the induction unit; the main control unit conducts delay synchronization on multiple paths of image signals and multiple paths of audio signals input by the first imaging unit, the second imaging unit and the recording unit, time shafts and water marks are embedded into the synchronized multi-path image signals and the synchronized multiple paths of audio signals, the multiple paths of image signals and the multiple paths of audio signals are combined into a same video and audio file through the main control unit, and then the video and audio file is stored into the storage unit. By the adoption of the monitoring method, video-mounted videos can be effectively turned on, and automatic monitoring and recording can be achieved under different conditions.

Description

technical field [0001] The invention relates to the field of a vehicle-mounted video monitoring method, in particular to a monitoring method for a vehicle-mounted video monitoring device based on dual cameras. Background technique [0002] In the fields of public security, prosecutors, and courts, patrol cars or related vehicles need to record the current law enforcement in the process of performing patrol tasks and other tasks, so as to protect the relevant rights and interests of those who are enforced and the enforcers, and retain on-site information to ensure that the incident can be traced. Retroactive. [0003] In the existing law enforcement recording process, a single camera device is generally used, and only one camera is configured. Moreover, the opening of these camera devices is initiated by law enforcement personnel, which is not conducive to transparency and fairness in the law enforcement process. In the actual work of grassroots units such as police station...

AI Technical Summary

Problems solved by technology

In the absence of effective monitoring records for police dispatch and law enforcement, the behavior of both parties in conflict cannot be effectively supervised, which will cause adverse consequences

The camera equipment installed on law enforcement vehicles such as patrol cars and police cars has a single function, which is basically based on law enforcement personnel, and only a single camera is used to monitor the conditions inside and outside the vehicle one by one.

Moreover, the opening and closing of these devices depends more on law enforcement personnel, which is not conducive to monitoring the law enforcement process
