A smart home is one in which all its systems can be controlled and monitored remotely. You can be far away, but can still check whether your doors are securely locked, whether the sprinklers are turned on, or even to prepare the house to be at the right required temperature when it is time for you to return. All these changes can be made by using a computer, a smartphone or any other device that allows you to connect to the various devices online.
Products that can be installed in a home to make it smart are convenient and in the long run, can save you a lot of money. They can make a home much more comfortable, safer and make it easier to manage your home, even if you are working in a separate job, that keeps you away from the home. Smart homes can have self-locking doors, fireplaces that can turn on and off automatically, house lights that turn off when there is no one in a room, start your oven even when you are not at home, warn you off leaking faucets and set your air conditioner to the temperatures that you are comfortable with.
Smart homes can have water leak sensors, valves that can be shut off remotely, water softeners, water conserving faucets, programmable thermostats, motion detectors, timed lights dimmers, security systems and many other devices that are constantly being developed.
When this level of automation is extended to city life, cities can also be smart, as well. You can have traffic lights that turn green as soon as traffic is indicated on roads, water meters that warn officials of spikes in usage that can denote leaks, and sewers and other utilities that tell you when they are in need of attention. Vehicles are also being automated, and the days are not far off when cities will have public transport that is driverless,and many other services that will become more efficient, because they are automated and do not need any supervision.
Smart cities will have governments that are more efficient because they are constantly monitoring and controlling all the services that they provide. The advent of smart homes and cities has been helped by the constant attempts to connect all devices that are responsible for comfort and convenience of homeowners and city governments, to devices,that can help in monitoring and controlling various actvities, utilities, and appliances.
It is more than likely that smart cities will come up much earlier before smart homes become widespread. The reason for this is, that automation, which is the crux of smart homes and cities, is expensive to install. Cities will have a larger budget that makes it easy for them to install the required devices. It is also a fact that automation does reduce staff and supervision costs, which can actually result in huge savings that these authorities are constantly trying to achieve. It is a well- known fact that the installation of CCTV and other detection devices has led to decrease in crime rates and hence the costs of policing.
