However, analog broadcasting systems transmit audio content through radio signals. This digital transmission mode enables the IP broadcasting system to have a wider dissemination range. As long as the receiving devices are connected to the network, broadcasting can be listened to worldwide.
• Improvement in Sound Quality: Since the IP network broadcasting system transmits audio content in a digital way, it can achieve high-definition sound quality. In contrast, the audio transmitted by analog broadcasting systems is affected by radio signal interference, and the sound quality is relatively poor.
• Enhancement of Flexibility and Interactivity: The IP network broadcasting system has a high degree of flexibility. It can update broadcasting content at any time according to needs, and adjust broadcasting time, volume, and audio content in real time through the network management platform. In addition, it can also be linked with other Internet applications to achieve more interactive functions, such as user interaction and message leaving through mobile apps, WeChat official accounts, etc.

Potential Risks in the Security of the IP Voice Broadcasting System

There are indeed potential risks in the security of the IP voice broadcasting system. These risks mainly come from aspects such as network security vulnerabilities, illegal access, data leakage, and service interruption of the system. For example, the IP network intercom and broadcasting system of Hikvision was once found to have an operating system command injection vulnerability. This vulnerability allows attackers to execute arbitrary system commands through specific inputs, which may lead to the system being controlled or data being illegally accessed.

In addition, with the development of AI technology, the network security of voice communication also faces new challenges. For example, AI voice simulation technology can use the voices of a small number of users to generate the voices they want to imitate. While this technology brings novel experiences to users, it may also be used for voice fraud. For example, false fraud calls may be made by injecting the voice of the target person generated through AI voice-changing technology.

To prevent these risks, the IP voice broadcasting system needs to adopt a series of security measures, including encrypted communication, identity verification, access control, antivirus and anti-malware, firewall settings, data backup and recovery, etc. Meanwhile, system administrators should regularly update software, verify and encrypt communication content, deploy SBC to monitor traffic, and maintain backups of software configurations and installations to ensure the security and reliability of the system.
