What is the difference between shielded and unshielded wires for security cameras?
Shielded and unshielded wires are two types of cables that can be used for security camera systems. The main difference between the two is the presence of a shield, which is a layer of material that surrounds the inner conductors of the cable. Shielded wires have this extra layer, which helps to protect the signal from electromagnetic interference (EMI) and radio-frequency interference (RFI). Unshielded wires, on the other hand, do not have this extra layer and are more susceptible to interference.
In general, shielded wires are recommended for security camera systems because they provide better protection against interference. This is especially important in environments where there are many sources of EMI and RFI, such as near power lines, fluorescent lights, or other electronic devices.
