china roller shutter remote control is a remote control device that uses radio signals to control various institutions in the distance. After these signals are received by the remote receiving device, they can instruct or drive various other corresponding mechanical or electronic devices to complete various operations, such as closing the circuit, moving the handle, and starting the motor, and then these machines will perform the required operations. As a kind of china roller shutter remote control supplemented with infrared remote control, it has been widely used in garage door, electric door, gate remote control, anti-theft alarm, industrial control and wireless smart home field.
The difference between china roller shutter remote control and infrared remote control, infrared remote control and wireless remote control are for different carriers, infrared remote control uses infrared to transmit control signals, its characteristics are directional, can not be blocked, The distance is generally not more than 7 meters, and there is no electromagnetic interference. The TV remote control is an infrared remote control;
china roller shutter remote control uses radio waves to transmit control signals. It is characterized by no directionality, no "face-to-face" control, long distance (up to tens of meters, or even kilometers), and easy to be affected by electromagnetic interference. In the fields that require long-distance penetration or non-directional control, such as industrial control, etc., it is easier to use a radio remote control.
