Connectivity related to video surveillance systems

Plugs, adapters, connecting elements. This section is intended for connectors used in surveillance systems. Any surveillance system that you want to install requires, in addition to the basic components such as surveillance cameras and the DVR or NVR, additional elements without which the system cannot be functional. In the case of surveillance cameras, you will need power plugs to power the camera (if you opt for a power cable and not for a separate power supply that includes this plug). The BNC plug is used to connect the camera to the DVR via the coaxial cable. Without BNC plugs, video transmission between the camera and the DVR cannot be achieved. BNC plugs are used two at a time, one piece is mounted on the side facing the camera and the other is mounted on the side facing the DVR. The connectivity used in surveillance systems is quite varied, although it may seem simple at first glance, since there are situations when these connectors alone are not enough. For example, there are cameras that also support audio, and in this case, RCA jacks are needed to ensure the transmission of the audio signal via  cable from the camera to the DVR, as well as a microphone, if it is not built into the camera.
