Surveillance systems are very important for providing security to the building.
Video surveillance systems Miami is a rapidly growing industry. Video surveillance equipment is being deployed ever more widely, and with ever greater storage and ability for recall. The increasing sophistication of video analysis software, and integration with other sensors, have given rise to better scene analysis, and better abilities to search for and retrieve relevant pieces of surveillance data. These capabilities of “understanding” the video that permit us to distinguish “interesting” from “uninteresting” video, also allow some distinction between “privacy intrusive” and “privacy neutral” video data that can be the basis for protecting privacy in video surveillance systems.
Video surveillance is a broad term for the remote observation of locations using video cameras. The video cameras capture the appearance of a scene (usually in the visible spectrum) electronically and the video is transmitted to another location to be observed by a human, analyzed by a computer, or stored for later observation or analysis. Video surveillance has progressed from simple closed-circuit television (CCTV) systems, that simply allowed an operator to observe from a different location (unobtrusively and from many viewpoints at once) to automatic systems that analyze and store video from hundreds of cameras and other sensors, detecting events of interest automatically, and allowing the search and browsing of data through sophisticated user interfaces.
Video surveillance has found applications in many fields, primarily the detection of intrusion into secure premises and the detection of theft or other criminal activities. Increasingly though, video surveillance technologies are also being used to gather data on the presence and actions of people for other purposes such as designing museum layouts, monitoring traffic or controlling heating and air-conditioning. Analogue video is being replaced by digital video which can be multiplexed via Internet Protocol over standard networks. Storage is increasingly on digital video recorders (DVRs) or on video content management systems.
A more complex centralized surveillance systems Miami where video from the cameras is stored at a central server which also distributes video for analysis and to the user through a computer interface. Video analysis is carried out by computers (using conventional or embedded processors) and results in the extraction of salient information (metadata) which is stored in a database for searching and retrieval.
More sophisticated distributed architectures can be designed where video storage and/or processing are carried out at the camera, reducing bandwidth requirements by eliminating the need to transmit video except when requested for viewing by the user, or copied for redundancy. Metadata is stored in a database, potentially also distributed, and the system can be accessed from multiple locations. A key aspect of a surveillance system is physical, electronic and digital security. To prevent attacks and eavesdropping, all the cameras and cables must be secured.
