At present, there are many brands of network cameras, network hard disk recorders and switches on the market. In response to these situations, Chitian electronic technicians developed a variety of pickups and related accessories to match the different audio connection modes of the front-end and back-end products in the market, for example, some well-known network cameras such as Haikang, Dahua, etc. Simply connect our pickups to the network camera's audio interface and share the power with the webcam. In this way, the cost of wiring and external power supply is saved, and it can be described as double benefit. 
As shown in the above picture, this network camera has an external pickup. Simply insert the 3.5 inch male end of the audio power cable (1 meter and 5 meters optional) that we have equipped into the LINE port, and use the second connector and the network camera at the same time. Share the power supply. The other end of the three wires can be directly connected to the pickup.

In the monitoring project, the traditional analog system equipped with the pickup technology is not complicated. As long as the DVR supports audio, three shielded wires from the front end to the back end can be easily resolved in the general environment. However, with the continuous deepening of the digital age, large-scale popularization of networked hard disk video recorders, switches, and network cameras in surveillance systems has resulted in higher and higher recording requirements for the security industry. At this time, purchases are made on Taobao or on the counters of the electronics market. The pickup (recording head) is installed on the project and obviously is difficult to hand over.
