* Supports PTZ control of remote venues.

* Supports switching of mainstream video signal sources, as well as audio input and output during meetings;

* It has a USB interface and supports access to USB storage devices. It supports conference recording function and can directly record the video and audio during the meeting. It supports program upgrades and data packet capture through USB storage devices.

* Supports video polling function, where you can select the polling window, polling time interval, and polling participants; supports voice activation function, where you can set the voice activation window, and the venue with the loudest voice will automatically switch to this window;

* Support wireless sharing function. You only need to install a software on your computer and connect it to the terminal through the network to realize the wireless sharing function without external hardware devices.

* No registration is required. You can join the corresponding meeting by simply entering the meeting number. You can choose to join in the interactive meeting mode or the live broadcast mode.

* Support third-party systems to call the terminal through API to adjust the camera, set banners, switch screen layouts, control the speaking rights of each venue , etc.

* It has rich audio and video interfaces, with 4-channel audio input interfaces, including HDMI×1, 3.5mm port×2, and RJ45×1; 2-channel audio output interfaces, including HDMI×1, 3.5mm port×1; as well as 3-channel HD video input interfaces and 2-channel HD video output interfaces, both of which support 4K60.

* It supports the repair mechanism when IP network packet loss occurs. When the network packet loss rate is 30%, the sound is clear and continuous, and the video is clear and smooth without any lag or mosaic. When the network packet loss rate is 80%, the sound is clear and smooth and can be accurately understood.

* Super strong network adaptability, automatically adjusting the resolution according to the network to ensure smooth meetings.

* Supports automatic noise suppression, automatic gain control, automatic echo cancellation, lip synchronization and other audio processing functions.

* It supports venue mute and block functions, and the venue sound output volume is adjustable.

* Support voice priority and QoS policy mode.

* It supports IPV4 and IPV6 protocols, supports NAT traversal, has the ability to cross routers and firewalls to ensure system security; and supports national encryption algorithms.

* It has good management and maintainability, supports local audio and video loop diagnosis functions; one-click local audio and video testing; supports network ping testing on the operation interface; supports query of call logs and historical records.

* Supports viewing media information of audio, mainstream video, and auxiliary video, including protocol, format, bit rate, number of sent and received packets, amount of sent and received packet data, packet loss rate, number of lost packets, jitter, delay, sending and receiving addresses, whether encrypted, etc.

* Supports power management of the device's power-on startup and fan switch, and can configure whether the device automatically starts up and enables the fan.

* The terminal has built-in data conferencing functions such as electronic whiteboard, electronic voting, and file sharing to meet the application needs of scenarios such as remote training and teaching.

* With the banner function, you can add a banner on the terminal screen and set whether to enable the banner and the font size, font color, and background color of the banner.

* It has the function of annotation on auxiliary streams. Real-time annotations can be made on the auxiliary stream screen when sending or receiving auxiliary streams. Three brushes of different thicknesses and five brush colors can be set, as well as annotation graphics such as circles, squares, arrows, and lines. When sending auxiliary streams, you can set whether to open annotation permissions to the participants for joint annotation.

* It has the function of web interactive electronic whiteboard. You can operate the electronic whiteboard on the terminal control web. You can set three different brush thicknesses, ten brush colors, and annotation graphics such as circles, squares, arrows, and lines; set a solid color background or a picture background; when operating the electronic whiteboard on the web, the terminal output screen will synchronously follow the display of the electronic whiteboard content; you can set the electronic whiteboard to be pushed on the same screen, and other participating terminals can view the same whiteboard content. The electronic whiteboard supports paging and can support 5 pages.
