A smart lock is a non-labor-saving locking system that is intended to do automatic locking and unlocking of a door by receiving such signals from an authorized electronic device using a secure wireless transmission and an encrypted key to successfully perform the unlocking process. It operates on two different modes, manual and automatic, and requires only one key for both operation modes. One important feature of this type of security system is its tamper resistance factor, which means that it is more resistant to forced opening than conventional deadbolts or other locking devices. Some examples of smart locks include biometric access control, keyless entry, proximity cards, PIN codes, proximity readers, radio frequency Identification (RFID) cards, or OBD-related technologies. This type of security system is used not only in residential or commercial environments but also in military applications. They are commonly used in airports, offices, banks, hospitals, and security forces’ command centers, military bases, and other secured areas.
Most smart locks today operate using an embedded processor that communicates with the corresponding door or window using radio frequency. The embedded processors are generally based on a computer chip technology and can communicate with a wide range of devices including automobiles, household items, cameras, video recorders, personal digital assistants (PDAs), cellular phones, handheld computers, watches, and other similar items. In fact, the most popular embedded processor is the Bluetooth technology enabled OBD reader card, which can read and communicate with other devices including computers, mobile phones, digital cameras, lap top computers, smoke detectors, televisions, and other items.
There are three main types of smart lock technology that can be used to provide a higher level of security. These are OTP (off the shelf smart lock software), PSK (shapless smart lock), and Trusted Voice technology. With OTP and PSK services, the user provides a one-time pin code or a series of numbers to unlock the door or window. Users can also select a trusted voice in order to completely eliminate the need to type a code or even read a document in order to bypass the authentication process. With Trusted Voice and TET (technology inside the TET technology) users are able to use their voice as a one-way link between themselves and the device they are trying to unlock. This is in contrast to the traditional biometric methods such as fingerprints, iris, or finger print recognition which are only able to provide limited protection.
