cylinder
One of the most common variants of the mechanism to be used for installation on the door. The principle of operation of such systems is based on the installation of cylindrical beams inside the larvae, which are arranged at a certain level.
Important! Such variants difficult to open using the master key.
However design can easily penetrate insideTo open the door. therefore the choice of such a mechanism should not buy the version with additional protective plates.
transom
The least effective means of protection against hacking. First of all, this is due to design features of the system.
Key to such locks is a flat metal bar with grooves at the two ends. These grooves contribute to the opening of the lock.
Important! On the inner side of the door, such systems usually have a special handle for easy opening. This is the weakest point, which is used by hackers.

Key to such systems resembles a large cylindrical rod at whose end located on both sides of the metal plates with a special configuration of the grooves.
Important! The more key grooves, the higher the degree of protection.
In addition, such constructions They have a large volume and weight, Making it difficult to break them.
electronic
Are relatively new, so their the cost is much higher compared with other models.
Reference! The presented version of the hardware provides security due to special character sets, electronic keys or cards.
In most cases, the criminals do not know how to break into the design, so just pass by. That is what is required for safety.

fourth grade
It is the most effective way to protect the house. Such a mechanism will expose approximately half an hour with a set of all the relevant devices and appliances.
Types of locks Installation
