In order to maintain their property in integrity, people are ready to install even the highest quality locks. On this issue, residents do not like to save. In addition to locking systems, sensors, electronic systems and video surveillance cameras are installed. The simplest among high-quality mechanisms should be called a combination lock.
Electromechanical locks are installed both in the entrance and in the office and so on. The main thing is to choose the right model, to understand which room is created for which.
Castle Reliability
Before you know the subtleties of choosing such a device, it should be noted what it all started with. The first attachments of this type appeared in antiquity. They are not much like modern options. In addition, embedded models are more popular. But they all have a common virtue. It is impossible to open them with a master key, since there is no keyhole. In addition to this plus, it is necessary to note the excellent design, as well as the presence of a special code that allows you to open the door. Symbols can only be known to those whom their owner trusts. The device of a mechanical combination lock is quite convenient.
Thanks to these qualities, this type of castle has won the love of people in many areas of life, from use in ordinary residential premises to industrial warehouses and workshops.
Comparison of code and conventional devices
Among mechanical devices, the presence of mortise and overhead options should be noted. But they got the same drawback: they can be opened with a duplicate key or master key. Therefore, not all options can ensure the reliability and safety of property.
However, mechanical combination locks appeared on the market. They got a greater number of advantages: they tolerate low and high temperature conditions, high moisture levels and mechanical breaking. In addition, a key is not needed to open and close the door.
At the moment, combination locks have received many modifications. They are divided into mortise and overhead, can be cylinder and level. Electromechanical locks are also distinguished.
The differences are in the methods of closing the door. Often, such locks are used in safes. During opening, the lock clicks. Everyone should understand that it depends on the design of the system. Under the circle on which the characters to enter are located, there are discs. If the first digit is entered correctly, then the clove goes to the second number. Then the person will hear a click. Such models of locks have an increased level of security, they are often used for safes.
Another type of castles - having several circles. Often these can be found on suitcases and on bicycle cables. The design, unfortunately, is not as reliable as the previous one. Why? It has no more than 1 thousand combinations. If the cracker has decent experience and calls himself a professional, then to open such a lock he will need no more than 15 minutes.
Among the mechanical combination locks are digital. They have no clicks, but they got their flaws. If the code is repeated for a long time and does not change, then the keys are erased, so the cracker will not even have to think which symbols are used.
Criterias of choice
Before you buy a castle, you should consider what degree of protection is needed, in what conditions the device will be used (street / room) and understand what budget is allocated. Only after clear answers to these questions can you already imagine approximately what model a person needs. This should be based on. First of all, it is worth deciding whether a mechanical or electronic option is needed.
If you need a mechanical combination lock for the gate, you can use the digital version.
