Vidéosurveillance comprendra toujours tout où partie des équipements suivants : les caméras, les moniteurs, l'enregistrementanalogique ou numérique,les équipements de gestion, l’interconnexiondes différents équipements.
Avant de rentrer dans le vif du sujet, il est important de rappeler certains fondamentaux, sans lesquels la compréhension des équipements et des principes d’un système de vidéo surveillance ne serait pas parfaite
La sécurisation des biens et des personnes est devenue une préoccupation majeure de notre société.
Technological developments in electronic security due to ICT (information and communication technologies) are inexorably gaining access to electronic security markets and modifying them thanks to the digitization of the components of the security chain. The growing importance of IT and telecom skills means that video surveillance installation studies must be treated with rigor at the risk of ending up with an obsolete installation causing serious damage. The establishment of a security installation – whether it is the fight against malicious acts, the need to control the flow of illegal emigration, the smuggling traffic, the control of comings and goings, the protection of an industrial site or military, remote viewing of a chain store, etc … requires a methodical and pragmatic approach so that the choice of the final technical solution validates the need for a video surveillance installation, which is often associated with other security systems such as access control, intrusion detection, fire detection, technical alarms, monitoring center, security, etc. Video surveillance can therefore offer a valuable visual aid in preventing, locating and quickly resolving problems, and even anticipating their recurrence. Throughout this guide, you will find a description of most of the products found in the different types of video surveillance installations. I hope it gives you a chance to take a step back before embarking on an installation project. There are often gaps between theoretical study and realization … This guide has three objectives:
– Indicate what is important to understand in the systems approach, without knowing the underlying electronics and IT in detail;
– Describe as much as possible the chain of acquisition, transmission, reception;
– Define a need and match the technical solutions to it without omitting economic considerations.
Enfin, ce guide ne vise pas à vous donner une collection de recettes miracles mais bien à vous fournir les connaissances techniques et méthodologiques qui vous permettront de prendre les bonnes décisions.
