What frequency does CCTV use?

There are 2 frequencies in use, 2.4GHz and 5.8GHz. In theory 5.8 GHz wireless transmission is supposed to suffer less interference than 2.4 GHz but that is changing as more and more devices switch to the higher frequency. The higher frequency also tends to be blocked more readily by solid objects such as walls.
