The main task of security systems is to prevent unauthorized access (penetration) into the room. Protective systems should also prevent the occurrence of dangerous situations due to smoke, gas content, water of water, etc. D., supplement and increase the efficiency of working security services.
Modern protection systems are not only a set of hardware (detectors) that signal the security service at the time of influence on the protected object or the owner of this facility about the illegal actions that are taking place. The most optimal option today is the use of multinformative systems and multifunctional devices based on computer technology.
A universal and effective device that allows you to get the most complete information as soon as possible and determines the operational response to the emergency situation, is a video recorder. This device, in addition to recording and playing a video of the data from observing surveillance chambers, can perform the following actions: give a sound signal (anxiety) through built -in speakers or an external device (security remote control, siren, on a mobile phone on SMS) when a detector is triggered).
Today, there are both standard digital and more modern network models of DVRs, such as Hikvision brands, which have great software flexibility and are able to provide, unlike digital devices, regularly remote access to video information, its viewing/transmission to the central remote control. The advantage of the network type of devices is that with their help it becomes possible to work with a large number of distributed objects, for example, such as an extensive transport system.
Thus, security systems of video surveillance provide versatile information about offenders or emergency situations at a protected facility, and on its basis, security officers can evaluate the real degree of danger and make the correct, adequate decision. The image recorded from cameras to digital media can be used as evidence of guilt and damage caused by offenders, as well as the accuracy and need for security actions.
