What is digital-analog integrated network interphone and mobile interphone
Digital and analog integrated network interphone, mobile interphone is a new communication device (which can be simply understood as the combination of mobile phone+interphone function) composed of a radio transmission device (such as antenna, radio frequency part, etc.) and a digital communication system (such as wireless telephone network, digital network, etc.).
In China, the use of digital-analog integrated network interphone is just beginning, but with the continuous development of wireless communication technology, digital-analog integrated network interphone will become more and more popular.
Traditional analog interphones can only support communication in a single mode. With the wide application of digital interphones, digital analog compatibility has undoubtedly become the current mainstream. Digital analog integrated network interphones include analog network radio and network telephone.
1. Analog radio uses analog frequency to transmit voice, which is widely used in the public security industry;
2. Digital radio uses digital signals to transmit voice, which has higher voice clarity than the first two methods;
The digital-analog integrated network interphone is equipped with IP68 protection level, voice+video remote joint dispatching, to achieve efficient decision-making, and GPS+Beidou positioning.
It is less used in the public security industry because it will be more widely used in mobile communications, such as military maritime, land, air force, public security, high-speed rail, railway and other industrial departments.
The digital-analog integrated network interphone can be used not only for short distance point-to-point calls, but also for public network interphone or vehicle-mounted radio calls;
When used, software or hardware can be used for secondary development to achieve multiple functions, key voice intercom, data, video and integrated application diversification requirements.
The digital-analog integrated network interphone can be used as a standby telephone, and can also form an interphone cluster with mobile phones.
