Security and fire alarms have become one of the most necessary attributes of every facility, from a haunted house to a large establishment, in our world filled with complex and also unexpected events. The achievements of modern optics and electronics have made the work of physical protection simply ineffective, fulfilling almost all the functions of the living guard with great success. Technical systems are fast, don't need sleep, and most importantly are reliable – they can't be captured in any way. When quality items are used and cared for properly, these systems can be operated for decades without ruining them.

The sensitivity of infrared motion warning devices, which Safe Life deploys more often in security alarms, exceeds cat eye sensitivity by more than 60%. And the spectral sensitivity of the glass detector is such that even in the background of the sound of a shaker plate being tested, it is possible to distinguish the sound of glass being cut with a diamond. Fire warners and optical flame registers don't go perfectly. However, the most important thing in our modern digital life is the speed and the volume of information being processed.
