CCTV Watches the World Go By Article excerpt CLOSED - CIRCUIT surveillance systems used with other methods of access control support security departments at land transportation facilities, airports, and seaports. They increase security officer efficiency and productivity, and the end result is a more secure facility At first glance, securing land transportation facilities may seem to be an overwhelming task, but taken in sections, such facilities can be easily secured with the help of CCTV CAMERA The inner perimeters of bus, train, and subway stations can be defined as the entrance gates to various platforms or terminals. In these areas, CCTV systems are used both as monitoring devices and as deterrents CCTV cameras monitor passenger activities and allow security officers to watch for criminal action, disturbances, and passengers who may need…
Computer controlled analytics and identification Computer controlled cameras can identify, track, and categorize objects in their field of view Video Content Analysis (VCA) is the capability of automatically analyzing video to detect and determine temporal events not based on a single image. As such, it can be seen as the automated equivalent of the biological visual cortex A system using VCA can recognize changes in the environment and even identify and compare objects in the database using size, speed, and sometimes colour. The camera’s actions can be programmed based on what it is "seeing". For example; an alarm can be issued if an object has moved in a certain area, or if a painting is missing from a wall, or if a smoke or fire is detected, or if running…
Educational apps Virtual light studio A camera is only as good as the light available. In the Virtual Light Studio application above, you can see how different a scene do appear, depending on how much light there is, what type of light you're using and where you place your lighting When the application opens, the time is set to noon. You can set the slider to different times of the day and see how the natural light decreases or increases To add an illuminator, click On in the menu to the left and select either 50° or 100° beam angle To move the illuminator sideways or up and down, click the arrows To better visualize the placement of the illuminator, click the bottom thumbnail on the right To change between…
Network cameras can be classified in terms of whether they are designed for indoor use only or for indoor and outdoor use. An outdoor camera requires an external, protective housing unless the camera design already incorporates a protective enclosure Network cameras, whether for indoor or outdoor use, can be further categorized into fixed, fixed dome, covert PTZ, and thermal network cameras Fixed network cameras A fixed network camera is a camera that has a fixed viewing direction once it is mounted. It may come with a fixed, varifocal or motorized zoom lens, and the lens may be exchangeable on some cameras. A fixed camera is the traditional camera type where the camera and the direction in which it is pointing are clearly visible. This type of camera represents the best choice…
High resolution IP-based cameras are not restricted to the low resolution of analog cameras. With a 5-megapixel IP camera, you get ten times more detail in your images than with an analog 4CIF Analog cameras have a maximum resolution of 704 x 480 pixels (4CIF). With an IP camera you can get increased resolution, including HDTV (720p/1080p) and even as high as 5 megapixels (2560 x 1920). This means you can either cover a much larger area in your scene, or get a highly detailed image to meet more demanding identification requirements. With IP-based cameras you also have the choice of various aspect ratios. This makes it easier to capture wide scenes and enables you to focus your coverage where it is most needed With a high resolution camera…
Modern video surveillance in airports requires flexible solutions which fulfil stringent quality and security demands: Distributed cameras, recording and transmission of video signals, live presentation, use of digital networks, intelligent picture processing, integration of audio channels and control as a video system via a higher-order (often already existing) building-management system Due to the layout of modern airports with numerous separate buildings and areas, the need arises for multi-area surveillance systems with the flexibility to set up secondary control centres as well, for example. Emergency scenarios and the integration of mobile control stations also play an important role e.g. iPhone/iPad Picture Generation The security requirements at airports are extremely high. Whether on the airfield or in the hangar, the terminal buildings, car parks or access roads: At airports, huge premises with…
Police forces around the globe are depending more and more on CCTV to solve crimes and catch criminals. In the case of the Boston Marathon bombings, which killed 3 people and injured a hundred others, police went through hundreds of hours of video footage to identify the two terrorists, who planted the bombs. However not all Americans are in favor of more video surveillance. In a recent poll, only about 40% of those asked said they wanted more TV cameras in public places Currently police rely not only on public TV cameras but also on private cameras that have been installed by businesses and other private citizens over the past few years. Together they guarantee that big cities are constantly observed and police can concentrate on crime hot spots. With video…
Gas station surveillance cameras have existed for at least the past decade or two. They are usually found outside the gas station, with a broad view over the entire gas fill-up area. In past years, they were of poor quality and had limited recording time, which made them very ineffective. However, the truth of the matter is that these days, technology has come a long way and the cameras that monitor the entire gas station are much more advance One big change recently is that gas stations are no longer monitoring just the fill-up area when they are doing surveillance. They are monitoring inside the store as well. The truth of the matter is that most of the robberies in gas stations happen in the store, and gas…
