A smart lock or smart lock is an electromechanical lock that can be unlocked or locked by input from an authorized device. These inputs are made through a wireless transmission protocol and a cryptographic key. A smart lock also monitors all accesses and can set automatic actions, such as sending notifications about problems to other devices. Smart locks are generally seen as a partial aspect of the smart home topic.
How Smart Locks Work?
The basic mechanism of Smart locks can be seen in various Arduino projects on DIY smart locks.
Like ordinary locks, smart locks consist of a lock and a key. The lock itself does not differ from ordinary locks with bolts or bolts that prevent the door from opening. Some manufacturers also continue to use the previous lock. In this case, the smart lock is essentially an attachment that, when prompted by the “smart key”, turns the actual key and thus opens the lock.

Unlike the lock, the key is not physical, but merely a digital code. This must be transmitted from an approved device via a wireless interface to the Smart Lock so that it opens. On the one hand, smartphones are used as devices that have a corresponding app installed. On the other hand, most smart locks also support special “key fobs” that transmit the corresponding code to the lock.
With many smart locks, it is not even necessary for the smartphone to be nearby. The transmission can also be done via the Internet. So you can lock the lock on the go or let guests into the house. The code that the device uses to open the smart lock is unique so that the smart lock can uniquely identify the device. On the one hand, this makes it possible to track at any time who used the lock and when. On the other hand, it is also possible to unlock certain devices only for a certain period.
Basics of Door Security
Door breaching is a method to force open a locked door. Wooden doors (teak, sal, neem, mahogany, walnut etc) are popular choices as material for doors since they look pleasant, protect us from heat, cold etc and carpenters are easy to locate to have one custom made. These days, wooden doors are not recommended since wood is easier to cut, and burn using power tools. Most recommend steel doors of double sheets with steel frames. These days, steel doors from various manufacturers are available in English-speaking countries which include insulation inside and offer a wooden finish. Commonly the intruders attack the mortise (or padlock) since hinges are difficult to attack.
Generally increasing the number of locks (2 versus 1), using an iron fence door to guard the main door and locking from both sides (that is possible for a few doors) forces the intruders to spend more time intruding. Locks with master keys are more insecure. A door which is made of weaker material or a weaker lock is more prone to be opened by an intruder. A weak door with a secure lock can not provide optimum security.
Essentially, the wall which is holding the door frame can be knocked off using a hammer or hammering drill. Measures should be taken to make it more difficult and time-consuming. Thicker 20-inch brick walls with more concrete are technically difficult to breech than a 5-inch brick wall.
Military from the opponent country can also try to breach a door. We should ensure adequate security of the windows, walls and doors, apart from Constructing Bomb Shelter at Home.
Security of Smart Locks
Smart locks visible from the outside can provide burglars with clues to possible valuables in the home. In the event of a power failure, a mechanical reserve key may be supplied by the manufacturer. So a power failure can render a smart lock to be similar to the common mechanical locks. Smart locks do not increase or decrease the security of the underlying locks. But they do increase complexity.
An infringement by breaking the door or picking is thus not more or less easy. Smart locks, however, offer some advantages when it comes to security. This allows for accurate tracking of which devices have been used to lock or unlock a lock. A smart lock can also be used to invalidate the key, for example, the smartphone, in case of loss or theft, which is not possible in the case of a mechanical key. As with almost all smart home devices, there are concerns about IT security and possible hacker attacks.
