1. General requirements
The portable synchronous audio and video system is a professional digital professional interrogation (interrogation) dual-disc direct recording equipment. It is mainly suitable for the mobile case handling needs of fixed interrogation departments of public security, procuratorate, discipline inspection commission, customs, security and other departments. It can be quickly installed and arranged in non-fixed interrogation rooms, fully capable of meeting the standard requirements of synchronous audio and video recording, and can be used as a fixed synchronous audio and video Device backup means. Prevent criminal suspects from retracting their confessions and falsely accusing the police handling the case, truly reproduce the entire interrogation process, and improve case handling efficiency.
2. Technical requirements
,
Synchronized audio and video host requirements
) adopts dual system
operation, built-in recording system, built-in high-definition camera in the equipment, and dual-disc burning , video display, hard disk backup, network transmission and other functions integrated into one, safe and stable.
) The device is equipped with an inch high-definition display.
) The device supports HD video input, has an output interface, and the resolution reaches *.
) The device can support single-picture, picture-in-picture, three-picture, and four-picture display modes for each channel.
) The video coding standard used for device video coding.
) The device contains an audio input interface, and the audio encoding adopts sampling encoding. It also contains a monitoring interface and a built-in speaker.
) The device has built-in dual optical drives, which can directly and simultaneously burn the audio and video information of the interrogation scene to a disc in real time. It also automatically formats and detects the validity of the disc before burning, automatically ejects discs that do not meet the burning requirements, and automatically closes the disc after burning.
) The device has a built-in hard disk, which can synchronize and back up the audio and video information at the interrogation site in real time to ensure the safe storage of data information. It also supports real-time synchronous burning of external mobile hard disks.
) The device uses dual optical drives, supports direct burning, and supports single-layer, single-sided double-layer, real-time recording. Use standard capacity discs, and the burning time can be selected from hours to hours. (A Blu-ray drive is also optional)
) The device has a video time uninterrupted function mode when replacing the disc. After the first disc is burned, re-insert the second disc. For two discs, the system will burn the recordings when replacing the disc to the second disc, so that the video time of the two discs will be uninterrupted.
) The device supports hash value calculation. After the disc stops burning, it will generate a unique hash value of the video file and write it to the disc, and ensure that the content of the video files on the two discs is consistent. The disc can be quickly ejected, and the disc ejection time is no longer than minute.
) The device has a built-in high-definition evidence collection module, which can support video evidence collection with high resolution and no less than frames/second.
) The device supports composite images, with a high-definition resolution of no less than frames/second.
) The device supports web pages to monitor the device's working status and control recording, etc.
) The device can be set up for scheduled recording, or the recording time of the first optical drive can be set. The second optical drive will automatically start burning when the first optical drive is close to closing.
) The device supports the simulation of audio signals into dynamic visual graphics, which are displayed simultaneously in the video screen, allowing you to instantly understand the audio information collection status.
) The device can flexibly adjust the background, color, position, display dwell time, etc. of the displayed content.
) The device has a built-in font library, five-stroke, stroke, pinyin and other input methods to facilitate input of case number, case name, case handler , case handling location, persons involved and other information can be superimposed on the video screen, and the display duration can be set by yourself.
) The device can directly play disc videos on this machine and provide functions such as pause and fast forward.
) The video recorded by the device is in a universal format and can be played by a universal player, making it convenient for court testimony. Audio and video single file burning and storage ensures the continuity of CD files, and universal video format file recording can be played using players such as Audio and Video, Baofeng Video, etc.
) The burned disc has a built-in key mark index. When the device is playing, you can select the key mark, and the device will automatically locate the key mark time in the interrogation for playback.
) The device can provide services. Users can remotely and synchronously watch the interrogation (interrogation) scene in real time through the browser, and can conduct one-way voice intercoms with the front-end interrogation (interrogation) personnel.
) The equipment has a built-in high-sensitivity temperature and humidity detection module, which reads the information from the environmental detection equipment in the interrogation room in real time and superimposes it on the video screen.
) The device can prevent the loss of interrogation synchronized burning data due to external influences during use. After an unexpected power outage and restart, there is no need to replace the disc. The original disc can be restored using a non-hard disk boot burning method to ensure the reliability of the disc data.
) The device has a router interface and supports inputting Chinese with an external keyboard
) The device has a router/adaptive network port and supports network expansion applications
) The device working environment range is ℃~℃ ~% relative humidity
