TRUTHS AND MYTHS
1. I have unbreakable door! – There are not unbreakable things! The most important factors are the time and noise. The time for dismantle any mechanical system is relatively short and in most cases - quietly. Through electronic locking systems is necessary first to determine exactly where is the lock , but even that to happen, the attack would be cutting the door which is sufficiently loud and slow process. It is much easier to enter through a wall or window, than to cut the door.
2. My mechanical lock is unbreakable! – There is not such lock! Any mechanical lock can be attacked in two ways - by the key or by drilling the lock itself. Examples and similar guidelines for such actions have in abundance in the internet which is accessible to everyone!

3. It is very easy to unlock all locks and there is no sense to give extra money and mount electronic locking systems! - That is not true! There is a substantial difference between the physical principles of fastening of the mechanical locks and electromechanical locks. Mechanical locks regardless of the type they have strictly fixed mechanical connection between the lock and locking systems, which allows through the latch to find the location of the lock and to attack it. In electronic locking systems there is no connection between the lock and electronic latch and you can not know its location. Even suggest where is the lock, because there is no benchmark point to attack the lock you should cut off a hole least 7-8 cm. If the electromechanical lock is installed in the case in order to attack you need to cut off all door!!
4. My lock is extremely reliable because it has multilateral fastening! - This is widespread deception, as a very rarely someone will shove and break open the door. It is much easier to break the locking mechanism (it takes seconds to several minutes) and from there to take in all points together, because even you have 100 points they are managed from a single place - the lock.
5. I have a secret locking latch! - Some people have installed hidden mechanical locking, which make assurance of the door double, and people think they are well protected. This is only when the thief is unprepared, but in the era of microelectronics a camera with a recording device is a miniature enough and can be placed so that all the "hidden" actions can be seen.
6. I use contactless electronic locking system and not being seen anything from outside, that makes me defended more than If I had visible electronic reader! - Widespread deception! The reader is hidden only to people who are not informed. Much more important is to can not detect the location of conclusions rather than reader, because even if you find the reader it has no connection to the lock. Contactless readers emit electromagnetic field which can be found with simple and widespread device /which is cheap enough/, which most of us use, but for various reasons. Much more important is the reader to be vandalresist, to withstand electric shock wand and other effects, because either way through it they can not open the door but can create a nuisance by blocking or burned it, which will create you a lot of trouble and loss of money. It is important the reader to be simple, reliable and cheap.
