Modern systems for audio / video door phones are among the most reliable and effective means to ensure the safety of residential areas. These systems make it possible to limit the penetration into the apartment of unwanted and uninvited "guests."

Usually codes required to open these locks are very simple and consist of several numbers. But after being used for some time, often pressed code button wear and begin to differ from others. This gives an opportunity to all who wish to enter the building to find out what the code is.
