The Videosurveillance systems have witnessed long periods of renewal until finally becoming one of the most essential instruments in any security system. Besides representing a valid deterrent for ill-intentioned subjects, they are the only instruments that allow for monitoring a situation in real time no matter where it is in the world. They are also particularly useful and effective in the reconstruction of criminal events (robberies, thefts, vandalism, fires, accidents, etc.) and in the analysis of industrial processes (warehouses, machinery, forklifts, boilers, furnaces, bridge-cranes, shops, etc.). Moreover, they make it possible to monitor people’s health (on motorways, in squares, parking stations, stadiums, fairs, shops, special access points, banks, hotels, etc.).
Ongoing technological innovation offers a wide range of Videosurveillance solutions, thanks to which it is possible to satisfy the most different needs, guaranteeing successful achievement of all the required objectives at the most competitive price. The various systems vary one from the other due to the devices used, and the complexity of the processing systems and data transmission, but above all due to the type of installation which can either be analogue or digital.
The analogue systems are currently the most widespread, despite exploiting technologies which are by now out of date. They consist of analogue cameras directly connected to the image processing and recording units (Digital Video Recorders). Despite being outdated, the analogue systems are still suitable for low-complexity situations. The main limitations include the poor quality of the video signals and the lack of scalability required by modern security solutions.
The ICT (Information and Communication Technology) convergence has given rise to new-generation digital systems which exploit technologies based on numeric signals designed for processing on modern computer systems. Hence there is a fusion between the computer network infrastructure and the Videosurveillance infrastructure that makes it possible to overcome the typical obstacles of the analogue systems while generating value and savings at the same time. The IP cameras, or camera network, generate a digital video flow in the LAN, WAN or WLAN data network that goes towards a PC able to manage the same, as well as recording and redirecting the flow towards the enabled operators.
– Extremely high quality of the image;
– Adaptable to multiple situations (low, medium and high complexity);
– Easily expandable and scalable;
– Easy data transmission over great distances;
– They preserve investments made for business continuity and data backup.
For years Cogen Openvision has been designing and installing video surveillance systems, offering in-depth studies and preliminary analyses in order to determine the best solution capable of satisfying the customer’s expectations and security requirements.
