9. Serial port: 1 RS232, which supports the network transparent serial port mode and supports the browser to directly control the 3-way camera pan/tilt; It also supports the cooperation between local mode and central control, and supports commands such as recording/stopping/switching local output/booting.
10, network coal flow delay: < = 1 sec;
1 1, recording format: MP4；;
12, recording and broadcasting function: synchronous recording and broadcasting/synchronous live broadcasting/on-demand/remote guiding/local guiding;
13, recording and broadcasting mode: multi-stream multi-picture (resource mode)/single-stream single-picture (movie mode)/single-stream multi-picture (picture in picture);
14, supports decoding of 1 rtsp/ts streams, and the resolution is 4k. The decoded code stream can be recorded through trial broadcast, live broadcast and on-demand recording, which supports full-screen display and independent sound output of the decoded code stream;
15, there are two dimensions to choose from. 1U rack-mounted all-aluminum wire-drawing oxidation case, the power consumption of the whole machine is ≤25w, which is energy-saving and environment-friendly;
16, the front panel touch screen supports echo mode/recording/system configuration/pilot control;
17, supports rtmp/http ts/udp ts/rtsp live broadcast protocol, embeds rtmp server function, and directly realizes web live broadcast without installing server software such as fms/red5;
18, which supports the browser to watch live broadcast directly without installing plug-ins, and supports html5 on demand;
19. Provide remote pilot software, which can monitor three pictures in real time, pilot all pilot streams in real time, and record them in real time, and support web button pilot; Support local mouse operation, touch screen operation (need to be equipped separately), support local pilot screen output and control;
20. Support the superposition of 4 lines of subtitles. Switch, font size, color and coordinates can be set for each line of subtitles, which can support both Chinese and English.
2 1, which supports the superposition of transparent background logo images and the automatic superposition of the opening and closing credits;
22. every recorded file and live stream supports H.265 HP5.0 coding of 1080p60 frame, which doubles the frame rate, greatly improves the effect and completely eliminates frame cutting; HDMI supports 4k resolution and 4k resolution live broadcast, recording and on-demand;
23. It supports recording at startup. When the hard disk is full, it will automatically cycle over the oldest file. Support automatic segmentation, segmentation time can be set, fully realize unattended automatic recording and broadcasting; Support ftp to automatically upload to the ftp server with the specified account and password;
24.USB3.0 interface: external USB flash drive and mobile hard disk are used for video recording; Wifi network card /4G network card to realize wireless network live broadcast. U disk/removable hard disk can be automatically recorded to local hard disk and external hard disk at the same time. Because of the pre-recording technology, you can pull it out immediately after recording, without waiting for time to export;
25. The program is solidified in the built-in chip, which is stable and efficient. Using embedded Linux system, it will not be poisoned, and it can be turned off at any time and turned on for a long time. Users can install their own hard disks and get rid of after-sales troubles completely;
26, support multi-level user management, divided into administrator users and ordinary users;
27. The mobile phone supports the app, and the Pad is used to watch live broadcasts and on-demand, providing Android and Apple versions of the APP. APP user and password are set by the administrator, supporting 200+ users. APP supports real-time live broadcast and vod on demand, with an end-to-end delay of less than 3 seconds, and the viewing page can be directly switched to any channel for viewing;
