Universal Receiver
A universal receiver is generally a radio receiver that is able to work with different standard transmitters. In case of home automations, this identify a radio receiver that works with almost any remote control in the market normally, used to open gates, garage doors, traffic barriers, entrance doors, etcetera. In other words, the universal receiver is able to recognize the code transmitted by other standard and not-standard remote controls, and is suitable to replace existing receiver permitting to add new and different remote controls on the automation system. Background The first electric garage door opener was created in 1921 bC.G. Johnson He realized there was a problem with garage doors being in the way when needed to be opened and found a solution that would change the way Americans lift garage doors forever. He called it the "upward lifting garage door." At the time that this invention was made many people were exchanging horses and buggies were begging for a more effi ...

Remote Control
A remote control, also known colloquially as a remote or clicker, is an consumer electronics, electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonics, ultrasonic tones. Present-day remote controls are commonly consumer IR, consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, chan ...

Garage Door
A garage door is a large door to allow access to a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. The operating mechanism is usually spring-loaded or counterbalanced to offset the door's weight and reduce the human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss. Description A typical version of an overhead garage door used in the past would have been built as a one-piece panel. The panel was mounted on each side with an unequal parallelogram-style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The weight of the door may be or more but is balanced by either a torsion spring syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Gate
An electric gate is a type of gate that can be opened and closed using an electrically powered mechanism. Electric Gate Options Driveway gate openers can be the rollback (sliding) type that retracks a gate along the fence or wall on wheels or bearing, or the swing type that draws the gate open or closed on hinges. They are usually operated by a remote controller or a sensor Articulated Articulated gate openers can be used for gates with wide posts allowing opening in small spaces. An easy system for DIY installers as they are simple to install but not as aesthetically pleasing as other motor designs. Also known as Crank arm operators, they are the main type of automation system sold in France, where low aluminium gates are often used. Underground Under-gate Jack operators usually control the gate by directly moving the pivot point of each gate leaf. This makes the unit ideal cosmetically and also allows for up to 180 degrees of leaf swing as required. However controlling th ...
