One, the type of wire is different
1, video surveillance cable: is a kind of wire and cable used to connect the security monitoring camera and the reality of the terminal (computer or monitor, etc.).
2, coaxial cable: is a cable that has two concentric conductors, and the conductor and shield and *** with the same axis.
Two, the role of different
1, video surveillance line: the role is to transmit the image data captured by the surveillance camera. Apply to transmission equipment and and all kinds of digital program-controlled switchboard, photoelectric transmission equipment, internal linkage and signal transmission between the distribution frame, for the transmission of data, audio, video and other communications equipment.
2, coaxial cable: used between television users and community antennas, can also be used by the telephone company, is also widely used in corporate intranets and Ethernet.
Three, the advantages and disadvantages of different
1, video surveillance line: the line must have a good shielding effect, the role of the braid is here, the shielding layer can be very good shielding off the outside world's interference (magnetic field, etc.), to the core of the signal transmission to provide a good protective environment.
2, coaxial cable: can support high bandwidth communications in a relatively long line without repeaters, the diameter of the thin cable on the 3/8-inch thick, to take up a lot of space in the cable ducts; can not withstand entanglement, pressure and severe bending.
