Video surveillance is a set of equipment designed for continuous visual observation of the protected object and its territory. Video surveillance systems allow you to control and simultaneously protect a large number of objects. Cameras for such systems are installed both indoors and outdoors.
The task of video surveillance includes providing operational and visual information about the situation at the guarded object. There are many different threats to which a guarded object and its occupants may be exposed. Theft, burglary, arson, and vandalism are the most common. To prevent such threats they install security monitoring systems.
Principle of selecting equipment for such surveillance is quite simple. It all depends on the importance of the guarded object. For example, for a small office building it is enough to install a simple system consisting of video recorder, monitor and the required number of analog cameras. Such equipment will serve for many years and will always provide prompt and timely visual information. But there are variants of security video surveillance consisting of professional equipment, which is able to study the situation at the object and create events. This is the so-called intelligent surveillance. Such systems usually consist of high resolution analog or IP video cameras capable of discerning and recognizing the smallest details. Security video surveillance systems can be designed on rotating video cameras which can be controlled by operators or cameras and which can track the movement of the intruder by themselves! In addition to video cameras, such systems are equipped with powerful video servers, which are capable of intelligent processing of video information.
How the system is organized
If we talk about the equipment, then to track the cameras you need a video recorder (which transmits the signal from CCTV cameras, which acts as a server), router Wi-Fi, monitor and remote access devices – smartphones, laptops, tablets.
The monitor for viewing video from cameras is usually located at the guard posts and entrance points. The local workplace is not a necessary part of the video surveillance system.
The video recorder is connected to a router to transmit information to the Internet. This allows you to remotely display the image on your phone, tablet, laptop or PC using a special application. Video recorders are encrypted, and access is given by username and password. This eliminates unauthorized connection to the security environment.
As you can see, the system is quite difficult for ordinary people to master, but, nevertheless, sometimes all the same, such an integrated security approach is used for private residences: rarely for apartments and more often – for private houses, where you need to monitor a large space.
In order to understand what we are talking about (and most importantly, what budgets) it is necessary to properly classify the video equipment. To monitor an apartment or private home use:
- cameras;
- video recorders;
- microphones with loudspeakers;
- server equipment;
- mobile devices;
- monitors.
Several video cameras with infrared illumination for seeing in the dark can be installed.
