Wireless cameras
Compared to conventional CCTVs , wireless cameras are becoming increasingly popular since no wiring is required prior to installation. They usually operate at a frequency of 2.4 GHz, with prices starting from around $60 for a basic model and higher prices for additional features. If you wish to buy from China, these cameras can be purchased online.
