Problems solved by technology
The development of traditional analog video surveillance technology has been very mature, with stable performance. Most analog video signals are collected by analog cameras, and then transmitted to the monitoring center through coaxial cables. Since the signals are inevitably subject to various interference and signal attenuation during transmission, There are certain difficulties in long-distance transmission. The use of analog optical fiber transmission solves the problem of long-distance transmission, but increases the cost of the system
In addition, because the analog signal transmission is usually carried out in the baseband mode, the structure of the camera and the monitoring terminal can only be in the form of one-to-one
It makes the topology of the whole system complex and increases the cost of integrated wiring. If the camera needs to be controlled, additional control lines are required.

Description
technical field [0001] The invention relates to a network camera for synchronous voice transmission. Background technique [0002] Video surveillance system is widely used in many occasions because of its intuition, convenience and rich information content. Products currently on the market include analog video surveillance and network video surveillance. The development of traditional analog video surveillance technology has been very mature, with stable performance. Most analog video signals are collected by analog cameras, and then transmitted to the monitoring center through coaxial cables. Since the signals are inevitably subject to various interference and signal attenuation during transmission, There are certain difficulties in long-distance transmission. Using analog optical fiber transmission solves the problem of long-distance transmission, but increases the cost of the system. In addition, because the analog signal transmission is usually carried out in the baseb...
