Technical Field

[0001] The utility model relates to the technical field of intercom communication, in particular to a voice intercom device based on 4G network ball camera communication. Background Art

[0002] With the rapid development of information technology, video surveillance and voice communication have become an important part of modern life and work. Especially in the fields of security, traffic monitoring, emergency command, etc., the demand for real-time and efficient video surveillance and voice communication is increasing. As a high-definition video surveillance device based on 4G network, the ball camera has been widely used in various places, providing strong support for security management and efficiency improvement.

[0003] However, the traditional application of 4G network dome cameras is mainly focused on video surveillance, and the integration and optimization of voice communication functions are relatively rare. In practical applications, users often need to conduct real-time voice intercom while viewing the monitoring screen to achieve more efficient communication and collaboration. Therefore, the development of a voice intercom device based on 4G network dome cameras has important practical significance and application value.

[0004] Most of the existing voice intercom devices use independent communication equipment, which is independent of the ball camera video surveillance system and lacks unified management and control. This not only increases the complexity and cost of the equipment, but also reduces the overall performance and ease of use of the system. At the same time, the existing voice intercom devices also have certain limitations in terms of communication quality and security, and it is difficult to meet the application requirements in complex environments.

[0005] Therefore, in order to solve the above problems, it is necessary to improve the existing voice intercom equipment or develop a new device based on 4G network ball camera that can perform both voice calls and video surveillance. Summary of the invention

[0006] In order to solve the problem that the application based on the 4G network ball camera has no integrated voice intercom function, the utility model provides a voice intercom device based on the communication of the 4G network ball camera.

[0011] Preferably, the upper cover of the waterproof box is sealed with a sealing ring, so that each component can be effectively protected from water and the overall waterproof performance is improved.
