video sender การใช้

Video senders have been a frequent cause of RF interference, particularly with car key fobs.
Most video sender systems will consist of three separate components, a transmitter, a remote control relay ( also known as a magic eye or IR blaster ).
Analogue wireless video senders can achieve typical operating distances of up to 60 metres ( clear line of sight ) with DVD quality ( 720x576 ) video resolution and stereo audio.
Radio transmitters of all kinds, including the garage door opener, cordless telephone, cellular phone, wireless video sender, wireless microphone, and many others fall into this category.
Electromagnetic interference at 2.4 GHz can be caused by 802.11b and 802.11g wireless devices, Bluetooth devices, baby monitors and cordless telephones, video senders, and microwave ovens.
