The entry features two primary inventions. Firstly, a sliding door designed to shield outdoor devices from sunlight and harsh weather conditions. This innovative door is user-friendly, as it only requires one hand to operate; simply push the handle, insert your card, and the door automatically closes due to a return spring. Notably, this sliding door can also be utilized for indoor devices. Secondly, there's a mounting solution that employs standard brackets and three screws for easy installation. This ingenious system is complemented by clear indicator lights and an LCD screen to ensure accurate input, along with dedicated function keys for programming purposes.
