Wireless remote control commonly used carrier frequency of 315mHz or 433mHz, it is a device for remote control of the machine, in life also get a more extensive role. The remote control uses the open frequency band specified by the state. In this frequency band, the transmission power is less than 10mW, the coverage range is less than 100m or does not exceed the unit range, and may be freely used without approval by the "Radio Management Committee". China's open band provides 315mHz, and Europe and the United States and other countries for the 433mHz, so exports to the country's products should use 433mHz remote control. Is a device for remote control of the machine.

Modern remote control, mainly by the integrated circuit board and used to generate different messages composed of buttons, today, wireless remote control has been in life has been more and more applications, to bring great Convenience, with the progress of science and technology has also expanded to many types. With arming / disarming / home arming / emergency four buttons. You can remote control of the alarm host can also be used when the emergency button. The use of SMT imported patch components, with push-button push-type protection device, metal shell small and beautiful, the launch of the conventional conditions for the two types, one for the remote control transmitter machine, two remote control transmitter module. The transmitter and remote control transmitter module is for the use of the difference in terms of the launch machine can be used independently, the receiver can be out of the terminal; remote control module is usually as part of the component, according to the actual needs of the definition, There are lines seamless docking, small and low price.
