The digital camera shooting, digital camera shooting and talkback function are integrated, dynamic and static field conditions can be digitally recorded in the law enforcement process, and the digital camera shooting, digital camera shooting and talkback function is convenient for the public security officers to use in law enforcement in various environments.
In the law enforcement process, the law enforcement personnel acquire dynamic or static law enforcement data of field, urban areas, factories and other law enforcement sites through the law enforcement recorder, and bring the acquired law enforcement data back to the control center, upload the data to an indoor law enforcement data acquisition workstation, and upload the data to a server through the indoor law enforcement data acquisition workstation, thereby facilitating the analysis and investigation of affairs. However, the existing law enforcement recorder usually only has the function of collecting and storing data, and the law enforcement data collection workstation is usually indoors, so that law enforcement personnel can upload data to the law enforcement data collection workstation only by bringing the law enforcement recorder back indoors, and cannot quickly send the collected law enforcement data to a server for processing, so that the law enforcement data is not uploaded timely, and the law enforcement efficiency is seriously affected.
The chinese patent application No. 201810247800.1 discloses a low power consumption law enforcement recorder for reducing the instantaneous communication load when a remote server receives data transmitted from a plurality of law enforcement sites, comprising: the three data acquisition units are used for acquiring distributed field data; the data fusion unit is used for fusing the field data acquired by the data acquisition unit; and the data transmission unit is used for transmitting the field data output by the data fusion unit to a server. Although the law enforcement recorder in the prior art can directly transmit videos to the server, the acquired data is more, the videos need to be fused, the videos cannot be accurately and efficiently acquired, and the working mode and the working efficiency are lower.
The invention discloses a working method of a patrol intelligent monitoring terminal, and particularly discloses a method for tracking a suspect, which comprises the following steps of S1, collecting facial feature information of the suspect and inputting the facial feature information into each monitoring processing server S2, collecting a face image in real time by a camera and transmitting the face image to the monitoring processing server S3, matching the face image collected in real time with the facial feature information of the suspect by the monitoring processing server, and S4, if the face image collected in real time is consistent with the facial feature information of the suspect, controlling a camera in an area where the suspect is located to zoom, shooting an amplified image of the suspect (corresponding to comparing the extracted face information with target person information, and if the extracted face information is judged to be consistent with the target person information, locking a target person by the zoom camera), and sending out an early warning signal. In the method for tracking the suspects, the monitoring area is divided into a plurality of sub-areas, and a plurality of cameras are used for continuously monitoring, so that the phenomenon that dead corners cannot be monitored can be avoided. In the above-described method of suspect tracking, different sub-areas are monitored by different cameras, so that the effect of each camera can be maximized without monitoring overlapping areas. The prior patent does not disclose how to acquire a user's use request, nor how to acquire wide-angle image monitoring information.
The invention discloses a certificate chain law enforcement system and a using method thereof, and discloses an executing method of the law enforcement system, which comprises the following steps that S1 law enforcement personnel enter the law enforcement system through a terminal provided with the law enforcement system to apply for law enforcement, S2 an identity information collector connected with an input module obtains identity information of an operator, a biological information collector obtains face information, fingerprint information and iris information to obtain biological combination characteristic information, the identity information, the face information and the fingerprint information are transmitted to the input module, then the identification information, the face information and the fingerprint information are transmitted to a multi-center verification module to initiate an identification verification and biological verification request (corresponding to the user obtaining request, the user carrying the identity information), S3 the certificate verification unit of the multi-center verification module verifies the certificate information of a law enforcement unit, if the auditing executor has the authority of executing the law, the face information and the fingerprint information of the executor are acquired by a biological information collector of the input module: an identity authentication request is sent to the multi-center authentication module, the identity authentication unit authenticates the identity information, the acquired face picture is compared with the face picture on the identity card in the identity information, storing comparison records through a multi-center storage module; the biological verification unit of the multi-center verification module verifies the fingerprint information and the iris information and compares the fingerprint information with the fingerprint information reserved in the biological information base, and storing the verification record through a multi-center storage module: if the face comparison is consistent with the fingerprint verification, the law enforcement application function (corresponding to the identity information of the user being verified, the user is allowed to use the fingerprint verification). This prior patent teaches to improve the safety of the use of the device by authentication.
For a law enforcement patroller, the identity of a target person needs to be confirmed in real time in a monitoring range, and a suspected criminal takes preventive measures in advance without influencing patrolling law enforcement actions of a user. In the early practice, a patrolman is matched with a photographer, and if an escaping target person goes on identity identification after patrolling, the patrolman carries out identity identification on a background system.
