Guangzhou Sizheng analyzes the wireless transmission of audio monitoring pickups for you

Wireless surveillance products can be roughly divided into two categories: First, mobile monitoring equipment through wireless transmission, monitoring of fixed or non-fixed locations, such as law enforcement vehicles through the roof mounted monitoring pickups or law enforcement officers carrying handheld monitoring pickups , Real-time sound collection on the scene of law enforcement, and then transmitted to the monitoring terminal via the wireless network; Second, through the mobile terminal equipment (such as mobile phones), access to a fixed monitoring microphone collected on fixed locations and venues, such as 3G hand ji monitoring . At present, mobile monitoring product forms mainly include: mobile phone (or mobile terminal) monitoring, bus movement monitoring, vehicle-mounted mobile monitoring (mainly law enforcement vehicles), law enforcement records, and mobile individual equipment.

The typical wireless monitoring system is mainly composed of four parts: the pickup part, the transmission part, the control and recording part, and the display part.

The pickup part is the front part of the wireless video transmission system and is the "ear" of the entire system. There are omni-directional "no dead ends" in the monitoring sites. In some cases, especially in outdoor applications, dust pickup, waterproof, anti-rain, anti-corrosion, anti-corrosion, etc. should be more attention to the choice of the pickup, dust, water and other products can be selected.


The wireless audio transmission part is the sound signal path of the system. In general, the transmission part single refers to the transmission of sound signals. At the same time, because the control center needs to control the pickups through the console, the transmission system also includes transmission of control signals.

The control and recording section is responsible for the control of the pickup and records the sound signal. At present, the technology of hard disk video recorders is more developed. It can not only record sounds but also monitor them synchronously.

The output section is generally composed of several or more speakers (speakers, headphones). In the case where the number of pickups is not large and the requirements are not very high, the speakers (speakers, headphones) are generally directly connected to the hard disk recorder. If the number of pickups is large and multiple speakers are required to perform complex switching of sound, a mixer must be provided.
