A transmitter is a compact electronic device that sends wireless signals to control various motorized systems, such as garage door openers, roller shutters, or curtain motors. Operating via radio frequency (RF) or infrared (IR), it converts user inputs (like pressing a button) into encoded signals that are transmitted to a corresponding receiver connected to the device. RF transmitters are widely used for long-range control (up to 100 meters) and can penetrate walls, making them ideal for outdoor applications like garage doors or barrier gates. IR transmitters require a direct line of sight and are commonly used for indoor devices such as curtain motors. Many transmitters feature rolling code technology, which generates a unique code for each use to prevent signal interception and unauthorized access. Our transmitters are designed for durability, with ergonomic designs for easy handling and long-lasting batteries. They support multiple channels, allowing users to control several devices (e.g., a garage door and a roller shutter) with a single transmitter.
