Wireless Camera Power Cable

Questions

Why does the wireless camera require a power cable?

"Wireless" is an electronics term referring to the method of information transfer. It has nothing to do with how the device receives power (electrical outlet, solar cells, batteries, etc.). The infrared signals sent from your remote to change the channel or increase the volume on your TV are a form of wireless communication. It simply means the information (voice conversation, computer data, video, etc.) is not sent through any wires.

Therefore, our cameras transmit their signals wirelessly, even though they have power supplies that plug into wall outlets.
