What is the difference between a conference recorder and a recording host?
The conference video recorder is a general term for the two products of the local conference video recorder and the remote video conference video recorder; the recording and playback host is a server-type device that relies on the computer and the network to perform live broadcast and partial video recording functions. Conference video recorders and recording hosts have some similarities, and there are more differences.
1, different fields of use
The conference video recorder is mainly used for occasions of local conference video recording and remote video conference video recording. When you hold a local conference, you only need to connect the camera and mixer audio to the recorder, and the recorder to the monitor or TV. The operation can be done directly on the recorder itself using the mouse or remote control. When holding a remote video conference, you only need to input it from the audio and video output interface of the video conference terminal device to the recorder. The recorder is connected to the TV or the monitor. The operation is also done directly on the recorder itself by using the mouse or the remote controller.
The conference recording host is mainly used to remotely transmit the conference live to other remote venues through the network. The conference scenes input by different cameras can be output to the network according to the live broadcast needs. The operation of the recording host must have a computer connected to the LAN, and the overall control is completed by the computer. At the same time, it must have a stable and reliable network, without computers and networks, and can't complete live broadcast and direct broadcast.
2, the video side is different
The conference video recorder is mainly based on recording the audio and video live audio of the conference to the hard disk storage of the access, and is mainly a video recording device. The high-profile conference video recorder also has the network remote live broadcast and video recording function. It can also record the live recording of the conference to a networked computer. It also supports computer control and live broadcast and download.
The recording host simply records a certain video to the hard disk in the machine, and the main function is to broadcast the web. Most of the machine components are mainly guided broadcast and live broadcast.
3, the operation difficulty is different
The conference video recorder is simple to install, simple in procedure, easy to operate, and requires no professional training.
The operator of the recording and broadcasting host needs to have computer knowledge, common knowledge of the server, understand the theory of network architecture, and generally need technical training in the professional stage.
4, equipment investment is different
Conference video recorders, whether it is a local conference video recorder or a remote video conference video recorder, although there are different models, but the equipment investment is relatively low, basically in the thousands to several thousand dollars, not more than 10,000 yuan. For example, Chunyuan Liying local conference video recorder WHD-04, even if you input 4 HDMI HD camera models at the same time, it is only more than 6,000 yuan. The more advanced MR-01 video conference recorder is only more than 5,000 yuan; the commonly used video conference recorder HDT-2B, only 3,000 yuan.
The recording and broadcasting host is relatively complex with respect to the equipment, and the machine components are many, and the cost is much higher. As long as it is a regular product, even if only one input device is used, it will be nearly 10,000 yuan, and most recording and broadcasting hosts will invest tens of thousands of yuan. Only a few cottage machines without quality function guarantees are priced at several thousand yuan, and recording and broadcasting hosts with less than 10,000 yuan are basically unreliable.
According to your actual needs, accurately and scientifically select products. If you want to conduct a stable and smooth remote live broadcast of the conference live, select the conference recording host; if you only need to complete the live video recording of the conference, you can select the conference recorder.
