What are the models of smart locks? Which castle is better to buy and how much does it cost?

There are different models of smart locks (smartlocks), which are designed for both entrance and interior doors. In addition, they can be used both as independent devices that are responsible for locking, and to carry out their work in a complex manner, together with standard locks, for which ordinary keys are used to unlock. The main feature of smartlocks is that they can be controlled remotely. To do this, you can use devices such as tablets, smartphones, central hubs.

Different smartlocks differ in the way they lock and open doors. For example, in order to open or close doors equipped with such a device, depending on its technical characteristics and principle of operation, it is necessary:

  • Enter a special, preset password (to enter the code, a stationary panel is used with which the device is equipped);
  • Use a special plastic card that is equipped with an electronic chip (the card is applied to a special reader, due to which the canvas is locked or, on the contrary, opens);
  • Use a special key fob that comes with the device (in this case, the key fob is used as a control panel).

Smartlocks equipped with special biometric sensors are also very popular. Such sensors allow reading patterns from fingerprints or the retina of the eyes. However, it should be noted that they are much more expensive compared to devices that are not equipped with biometric sensors.

To be able to control a smart lock using the Internet, it must be connected to the central hub with which the smart home system is equipped or directly to the gadgets of the home owner (smartphone, personal computer, laptop). For connection, wireless technologies Wi-Fi or Bluetooth are used. Also, a special application must be installed on mobile devices that allows you to remotely control the lock.

For example, thanks to remote control, you can get data on whether the entrance doors are closed or open at the moment, or receive notifications at the moment when someone tries to enter the house.


Compared to classic locks, electronic smartlocks have a higher level of security against possible burglary by intruders. A high level of security of the smart lock system is achieved due to the fact that:

  • A private channel is used to transfer all information between the smartlock and the user. This ensures a high level of protection of personal data and minimizes the possibility of information leakage.
  • Smartlocks, which are controlled by key fobs or special plastic cards, are equipped with 100 billion possible combinations. For this reason, finding the right key for them is not an easy task, even for specially designed hacker software.
  • Some types of locks are equipped with special biometric readers. Therefore, without fingerprints or scanning the retina of the owner of the house, it will be almost impossible to open them.

On a note! In the event of mechanical impact on the door, when intruders use a crowbar, a pry bar, a grinder, the smart lock will start giving signals of burglary to the owner's gadget. Also, some devices can signal a possible home burglary directly to the emergency services console.

Thanks to the use of modern high-tech filling, smartlocks are able to provide much better protection of home from burglary, as well as intruders. However, it should be noted that no device, even a smart lock, can guarantee 100% protection of a home from burglary. Therefore, together with such high-tech devices, it is recommended to additionally equip houses with alarm systems and motion detectors.
