Modus Operandi -Mode of Operation The basic mechanics of the electric powered, automatic garage door opener haven't changed much since it was invented by C.G. Johnson in 1926. But, the modus operandi, or way we operate the automatic garage door opener, continues to evolve with advancements in technology. This article briefly explores the history of the garage door opener. Or more specifically, door access control and the most innovative products on the market today. Very Revolutionary The gas-powered automobile movement began to replace horse drawn carriages at the turn of the 19th century but inefficient production made ownership impractical for most average people. Only the rich could afford the luxury of owning a horseless carriage. The transportation paradigm didn't fully shift until Henry Ford's vision of BUILDING A "MOTORCAR FOR THE GREAT MULTITUDE" came to fruition with the moving automotive assembly line and mass production of the Model T. THE MODEL T revolutionized transportation (and modern life as we know it) with personal transportation that was affordable to the American middle class. Production of the Model T peaked at more than two million manufactured in 1923, and as it became less of a status symbol and more the norm to own a car; the garage door industry was born of necessity. The word garage comes from the French word "Garer," which literally means to shelter or cover. Because many of the first cars didn't have rooftops, millions of new car owners needed a structure designed to shelter or cover their vehicle from the elements. While barns and carriage houses functioned as primitive garages, early car owners desired to improve this concept with added convenience, security and technology. Most of all, consumers needed an easier way to raise and lower such a heavy door. Some Things Never Change The earliest garage door openers were controlled by wired devices, not unlike like those still in use today. A keypad outside the door or a switch inside the garage were typical set-ups. However, it was only a matter of time before consumers demanded a way to control the door without having to exit the car. The wireless technology utilizing radio signal communications between a transmitter and receiver to control the garage door opener wasn't adopted until after WWII, where the same type of system was used to remotely detonate bombs. However, homeowners experienced an issue with these early radio controls. The problem being due to the shared radio frequency of the garage door remotes, not only could they open their own garage door- they could also open their neighbors garage door too! Not a good way to improve relations with your neighbors. Only a Phase? The multitude DIP switch system was introduced as the solution to the radio frequency problem. It works by setting the switches on the receiver and transmitter to the same fixed code. However, the limited number of codes available renders this system particularly vulnerable to security issues. While easily programmed, clever criminals could beat this system using code grabbers, scanners or even by manually entering different codes on any transmitter to gain access to the garage. Rolling code technology phased out the multi-code system with superior security capabilities. With rolling code technology, a unique code is generated every time the remote controls are activated, making it virtually impossible to hack the code. Rolling code technology has remained the standard with most automatic door opener remote controls on the market today. The Future Is… Now? We still use wired devices, multi-code and rolling code systems today. But what about the latest upgrades in garage door access control technology? Did you know you can control your garage door with your smartphone or tablet? Or that you can even use your voice to control your garage door? As fully-autonomous cars become a reality in the next few years, it won't be long before you can tell your car to open the garage door and park itself! North Shore Commercial Door wants to bring your garage into the 21st Century with the latest high-tech, access control systems and gadgets. LiftMaster MyQ Home Bridge Kit - Enables Smartphone Control for MyQ Products The LiftMaster MyQ Home Bridge Kit enables access control of your garage from your smartphone or Apple iPhone with the free MyQ mobile app. The MyQ APP allows homeowners to easily set up and control MyQ products, monitor and control the garage door and lighting from their mobile phone, and even sends real-time alerts about the status of the garage door and lights to your email or push notifications. It even works with Apple HomeKit and adds Siri voice control. With the MyQ Home Bridge Kit, you can control all your HomeKit devices from the Apple Home app using your iPhone, iPad, iPod Touch and even your Apple Watch. Genie Aladdin Connect - Smart Device Enabled Garage Door Controller The Genie Aladdin Connect uses your home's Wi-Fi to control access to and monitor your garage from anywhere with your Apple or Android mobile device. Just download the free Aladdin Connect mobile app to get set up and the Aladdin Connect will notify you whenever the garage door is being operated and by who. You can also remotely open the door for deliveries or repairs. You can even allow relatives or friends access without the need for a temporary password. The Aladdin Connect is compatible with most residential garage door openers, easy to install and set-up and even maintains a history report of the dates and times the door was used. What sets the Aladdin Connect apart from other similar products is it uses a sensor attached to the door itself to monitor the position, instead of monitoring the automatic opener. So even if the door is manually operated by disengaging the door from the opener, the Aladdin Connect will alert you to any change in the position of the door. Control up to three doors with one door control module by adding an additional door position sensor to each additional door. One module and one sensor come standard with the kit and additional sensors are sold separately. Goatee 2 Kit -Smartphone Gate & Garage Door Opener with Wireless Sensor The Gogogate 2 Kit is perhaps the most complete solution with the most value.

Though old Knob and Tube may have been ‘working’ in your home for a while, today’s homes require much more electricity than 1940's homes, before refrigeration, TVs, and phone chargers and smart home devices became standard electrical use in a home. Thus knob-and-tube is frequently overloaded, posing a fire hazard. Also the casing around the wire is old and vary brittle that make it easy to breakdown, expose wires over time, and in some cases, corroding copper wire due to insulation additives. Less resistant to damage than modern wiring, as components breakdown, stretch and sag over time, Knob and Tube can also suffer unintentional contact with surrounding materials, resulting in serious fire and electrical hazards.
It’s Lack of Ground Wire
Incompatible with 3-prong appliances Knob and tube lacks grounding, providing only a hot and neutral wire. This puts electronics at increased risk of damage as voltage fluctuations and surges have nowhere to go, putting your valuables, family and home at risk of shock and fire.
It’s Incompatibility with Moisture
Already underground, knob-and-tube is not rated for moisture and exceedingly dangerous when used in wet locals such as kitchens, bathrooms, laundry and utility rooms, and outdoors.
It’s Tendency to Be Overlooked
Knob-and-tube is frequently buried with insulation and pushed into contact with building materials and storage clutter. Designed to dissipated heat freely into the air, this results in a fire hazard. National Electric Code (NEC) requires Knob&Tube not be covered by insulation, or used in the hollow spaces of walls, ceilings, or attics where insulating materials can come into contact with the wiring and conductors. Just one of the many reasons most insurance companies refuse to cover houses with knob-and-tube.
The Frequency of Improper Modifications with Knob and Tube
Improper and unsafe DIY modifications are much more frequently found with knob-and-tube wiring than with modern wiring systems. Part of this is increased opportunity due to its age, as well as due to ease-of-access for splicing. Amateur modifications to Knob and Tube are so common, connections made with masking or Scotch tape (instead of electrical tape) are frequently encountered. Worse, the insufficiently trained frequently install fuses with an amperage too high for the wiring of Knob and Tube (to pair them with newer electronic appliances and devices), overloading and resulting in damage to wires, which over time breakdown, greatly increasing fire risk.
