Closed Circuit Television

Closed-circuit television cameras are very expensive and require a manned station, but with careful siting and the latest technology, they can see in moonlight and can set off alarms when picking up motion. 

An important principle is that security must be built in depth - otherwise known as defense in depth. In this context, it may be helpful to think of security as a set of concentric rings, where the target is located at the center. Each ring represents a level of physical protection (perimeter fence, building shell, security case) but the number of rings and security resistance will vary relative to the risk. The spaces between the rings may represent other defensive measures such as closed-circuit television (CCTV), security lighting, intruder alarm systems, etc. 

Review of the Closed Circuit Television and Video Tape Recording System for the Melt Pour Building in the 105mm Production Line... 

In which 100 cc could be polymerized. We used a pressure gage, rated from 0 to 140 pounds per square Inch. There were 3 type J thermocouples - one In the center of the solution, one In the reactor wall, and the third near the heater outside the reactor. The experiments were conducted In a high pressure bay and observed on closed circuit television. The Initial polymer concentrations of the test reactants were either 0 or 15 or 30 percent by weight. An electric heater controlled the ambient temperature of the nitrogen - purged reactor, and supplied heat to Initiate the reaction. 

Alarm systems can be integrated with fire detection systems, intrusion detection systems (IDSs), access control systems, or closed circuit television (CCTV) systems, so that these systems automatically respond when the alarm is triggered. For example, a smoke detector alarm can be set up to automatically notify the fire department when smoke is detected, or an intrusion alarm can automatically trigger cameras to turn on in a remote location so that personnel can monitor that location. 

Visual surveillance is provided through a closed circuit television (CCTV) system, in which the capture, transmission, and reception of an image is localized within a closed circuit. This is different than other broadcast images, such as over-the-air television, which is broadcast over the air to any receiver within range. 

We were among the first clinical laboratories to have a closed circuit television system. The recorder was an upright piano-sized Ampex console, with two 14-inch spools. They shuttled four-inch wide videotapes back and forth, like... 

Direct observation of subjects at all times by viewport or closed-circuit television. 

The available types of flame sensing detectors are ultraviolet (UV), infrared detection (IR), combination of these, and monitored closed circuit television (CCTV). These devices operate on the detection of certain wavelengths of light emitted by flames. They are used when there is a potential for fires that rapidly produce flame such as flash fire. 

The electrical control system is powered by means of 24-V batteries which are charged automatically from a rectified a.c. supply. All the control devices are located beyond the safety wall. The separator is monitored by a closed circuit television system. 

As a rule OPCW equipment is used for sample collection and handed to the ISP/facility representative who will perform the sampling activity. If ISP equipment is used for sample collection, the IT will prepare a respective equipment blank sample. Sampling can be observed either directly by an inspector or from an on-site close circuit television system. The sampling operation and subsequent chain of custody procedures must be well established between the ISP and the IT before activities commence. 

Medical Sources. All medical encapsulations are done in a facility which consists of a series of five interconnected stainless steel boxes which provide primary containment of process equipment and materials. Interconnections include transfer ports, drop-through tubes, and ventilation ducts. Each containment enclosure has a floor area of 1.52 m x 0.91 m the floor level is 0.76 m above the building floor. A pair of master-slave manipulators serve each containment box. A closed circuit television system and a telescope are provided for close-up viewing of incell operations and can be moved from cell to cell as needed. General arrangement of the facility is shown in Figures 13 and 14. 

The munition route following the unpack area is the Explosive Containment Cubicle (ECC) containing four different demilitarization machines which will be remotely operated. Operation within the ECC will be followed by closed circuit television surveillance. Since there is a chance of an explosive fire incident, the ECC is designed for explosive and agent containment. Each step in demilitarization of munitions is controlled by a computer which also stops the operations within the ECC when a problem develops or equipment maintenance is needed. 

In the petroleum industry, unattended bulk stations exist where the tank truck driver is alone when he selects cargo, connects lines, starts pumping, gages contents, stops pump, disconnects, and drives away. If an error or accident occurs, he is on his own. Some type of alarm or closed circuit television monitored at a... 

Some TEMs have a closed circuit television system fitted so that the images can be fed directly to an automatic image analysis system. 

Iv) a light source to illuminate the three-phase contact region from behind. It should be equipped with a heat filter to prevent temperature fluctuations and, hence, convection. The light can be either diffuse or collimated, with different effects. Experience has shown that diffuse illumination (5delding a silhouette) is preferable for closed-circuit television (CCTV) imaging, whereas collimated light is suitable for telescope-type measurements. 

A closed circuit television link has been incorporated into both microscopes and dynamic events are continuously recorded on video-tape. Detailed quantitative kinetics analysis can be perfonned on reaction sequences by single frame projection procedures. 

The PROTECT architecture consists of sensors deployed in various subway stations, complemented by closed-circuit television (CCTV) cameras that have automated and manual pan-tilt-zoom capabilities. These sensor and camera combinations provide data continuously to a centralized chemical-biological emergency management information system (CB-EMIS developed by Argonne National Laboratory) located in a centralized WMATA operations control center. In addition to the sensor and video data from the stations, train operation data and ambient meteorological data are also ported to the CB-EMIS system. Under normal operations, CB-EMIS can provide operator access to the multiple fixed and movable cameras throughout the metro system to assist law enforcement officers or firefighters. It also monitors the status of the sensor systems deployed in the metro. 

Preventing unauthorized access into a warehouse may require certain security features. Unauthorized access may be motivated by theft or other illegal or destructive purposes. There may also be a need to restrict employee access into an area of a warehouse storing toxic or potentially hazardous materials. The type and extent of security features utilized should be based upon the risk associated with unauthorized entry. Security features, such as door locks, alarm systems, closed circuit television (CCTV) monitors, should not interfere with required means of egress. 

Test operations for the stratification program were performed in accordance with previously prepared step-by-step written procedures, and were controlled from the control and data recording center at the Hydrogen Research Laboratory. Progress during hazardous phases of the operation was monitored on closed-circuit television. 

Closed-circuit television (CCTV) systems magnify print and small objects up to 60 times, with higher effective magnifications possible by close viewing. Users with vision as poor as 1/400 (20/8000) may be able to read ordinary print with CCTV [Fonda, 1981]. Some recent units are portable and contain black/white image reversal and contrast enhancement features. 

Effects on blood pressure, heart rate, lead IIECG, core body temperature, and locomotor activity are now most commonly conducted using animals with implanted telemetry devices (such as those from DataSciences) in rats, guinea pigs, dogs, pigs, or primates. Effects on behavior can be captured on video using closed-circuit television (CCTV) for dog and primate studies. Repeated administration and interaction studies can be performed. 

Companies are making increased use of closed circuit television (CCTV) to enhance security. Such systems can sometimes provide invaluable information as to how a process-related incident occurred.
