Difference between network cable and coaxial cable for video surveillance

1, video surveillance line: it is a kind of wire and cable used to connect the security surveillance camera with the real terminal (computer or monitor, etc.). ).

2. Coaxial cable: refers to a cable with two concentric conductors, and the conductor and the shielding layer share the same axis.

Second, the role is different.

1. Video monitoring line: used to transmit the image data shot by the monitoring camera. It is suitable for the internal connection of transmission equipment and various digital program-controlled switches, photoelectric transmission equipment and signal transmission between distribution frames, and is used to transmit communication equipment such as data, audio and video.

2. Coaxial cable: used between TV users and community antennas, also used in telephone companies, and also widely used in intranet and Ethernet.

Third, the advantages and disadvantages are different.

1, video surveillance line: the line must have a good shielding effect, and the role of the braid is here. The shielding layer can shield external interference (magnetic field, etc.) well. ) and provide a good protective environment for the signal transmission of the wire core.

2. Coaxial cable: it can support high-bandwidth communication on a relatively long line without repeater, and the diameter of thin cable is 3/8 inch thick, which takes up a lot of cable duct space; Can't withstand tangles, pressure and severe bending.
