Wireless CCTV is a relatively new technology that has been gaining popularity in the past few years. The main advantage of wireless CCTV is that it can be easily installed and moved around.
However, this advantage also has its disadvantages. The most important disadvantage is the lack of a physical connection to the power supply and internet, which means that it could be more difficult to find a good signal in some areas.
On the other hand, wired CCTV does not have these disadvantages as it has a physical connection to the power supply and internet which guarantees better signal strength.
