What is radio transmission for CCTV surveillance systems?
There are several ways of transmitting data over a distance, like using radio waves or sending the data over the Internet. Radio transmission for CCTV surveillance systems can only be done over a certain distance. There is no need for any wiring: CCTV surveillance cameras send the data directly to displays and hard disks, using radio waves (it’s just like using a radio transceiver). This is particularly useful when cameras need to be installed in places where you cannot pass wires.
Some models of CCTV surveillance camera use short-range radio waves, while others use WiFi or Bluetooth connections. The major differences between these different types of radio waves are transmission frequency (number of vibrations per second, expressed in hertz) as well as wavelength.
