En el centro de control existen unos monitores en los que se mostrarán estas imágenes.The images taken are usually transmitted to a control center, and transmission means may be used miscellaneous: wired by coaxial cable, fiber optic, via radio, etc. There are monitors in the control center where These images will be displayed.

El sistema incluye también un procesador, usualmente un ordenador tipo personal, que tenga la potencia suficiente en función de la cantidad imágenes a procesar, y en el que corre un software especifico que analiza las imágenes tomadas por las cámaras en tiempo real, discriminando sobre las mismas principalmente la existencia de llama o humo, y adicionalmente la existencia de otras sustancias, tales como gas o líquidos, que evidencien un escape o derrame de las conducciones o equipos correspon-
dientes.The system also includes a processor, usually a personal computer, that has sufficient power depending on the quantity of images to be processed, and in which there is a specific software that analyzes the images taken by the cameras in real time, discriminating on the mainly the existence of flame or smoke, and additionally the existence of other substances, such as gas or liquids, that show an escape or spill of the corresponding conduits or equipment.
teeth.

Asociado a dicho procesador se dispone un avisador, usualmente acústico y/o luminoso, que en caso de detectarse una incidencia generará el correspondiente aviso, que puede ser presencial en el mismo centro de control y/o remoto a través de, por ejemplo, redes internas o externas, de telefonía, etc.Associated with said processor, a warning, usually acoustic and / or luminous, that in case of detecting an incident will generate the corresponding warning, which it can be face-to-face in the same control center and / or remote to through, for example, internal or external telephone networks, etc.

Opcionalmente el procesador y el soporte estarán preparados para mostrar de modo automático las imágenes en las que se ha detectado la incidencia en alguno de los monitores del centro de control, con lo que se podrá verificar instantáneamente el alcance de la misma. También estará opcionalmente preparado para actuar sobre unos medios de extinción automáticos que corten o extingan la propagación del fuego en el mismo instante de su detec-
ción.Optionally the processor and the support will be prepared to automatically show the images in which the incidence has been detected in any of the monitors of the control center, so that the scope of the same can be instantly verified. It will also be optionally prepared to act on automatic extinguishing media that cut or extinguish the spread of fire at the same moment of detection.
tion.

Por tanto, con un mínimo número de cámaras se abarcará una mayor superficie que con detectores de humo, especialmente en estancias diáfanas. Por ejemplo, con una única cámara podrá visualizarse, y por tanto vigilarse, una gran superficie, del orden de centenares de metros cuadrados, con el consiguiente ahorro.Therefore, with a minimum number of cameras cover a larger area than with smoke detectors, especially in diaphanous stays. For example, with a single camera can be displayed, and therefore monitored, a large surface, of the order of hundreds of square meters, with the consequent saving.

Igualmente la utilización de cámaras, monitores y software especifico asociado habilitará al sistema a prevenir contra intrusiones si el software se prepara para detectar movimientos, generando también el pertinente aviso.Also the use of cameras, monitors and  associated specific software will enable the system to prevent against intrusion if the software prepares to detect movements, also generating the relevant notice.

Adicionalmente el sistema podrá incluir medios de almacenamiento donde quedarán registradas las imágenes que pueda interesar, ya sea directamente las de una incidencia, como también puedan ser imágenes tomadas cada cierto tiempo aunque no exista incidencia.Additionally, the system may include means of  storage where the images that can be registered interest, either directly from an incident, as well as they can be images taken from time to time even if there is no incidence.
