a monitoring device

Abstract

The invention relates to the field of monitoring equipment. It includes a main control unit, an imaging unit, a recording unit, a storage unit and a power supply, the main control unit is connected to the power supply, the imaging unit at least includes a first imaging unit and a second imaging unit, the first imaging unit is arranged outside the vehicle, The second imaging unit is arranged in the car; the main control unit is connected to the sensing unit, and is connected to control and synchronously open the first imaging unit, the second imaging unit and the recording unit according to the sensing signal of the sensing unit; the main control unit is connected to the first imaging unit. The multiple image signals and audio signals input by the imaging unit, the second imaging unit and the recording unit are delayed and synchronized, and at the same time, the time axis and watermark are embedded in the synchronized image signals and audio signals, and the multiple image signals and The audio signal is synthesized into the same audio-visual file by the main control unit and stored in the storage unit. The invention provides a monitoring device, which can effectively start a monitoring method for vehicle-mounted video, and realize automatic monitoring and recording in different situations.

Description

technical field [0001] The invention relates to the field of monitoring equipment, in particular to a vehicle-mounted video monitoring equipment 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 stations, civil cases and minor cases are general...

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
