CCTV systems

The purpose of security lighting is to deny the criminal the cover of darkness, which he uses to conceal his activities. In addition, strategically designed lighting can considerably increase the security value of other measures, and it can also assist the detection capabilities of surveillance (manned or CCTV) systems. 

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. 

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. 

Closed circuit television (CCTV) is now an integral part of many security systems. CCTV systems range from a single monitor with just one camera dedicated to monitoring perhaps a hotel car park, through to systems with many internal and external cameras connected to several locations for monitoring perhaps a shopping precinct. 

Where buildings or sites are unoccupied at night or at weekends, serious consideration should be given to the installation of CCTV as it has a high deterrent effect. It should be noted that CCTV systems which are not monitored have limited value. 

As in the case of all arson prevention arrangements, waste management should take into account the provision of adequate security lighting, CCTV systems, fencing and possibly security guards.

Essential reactor status information may be conveyed to various locations. Two schemes have been used for this purpose. In PARR/1 a closed circuit television (CCTV) system of the plant has been used for the distributed display. In this case the video output signal is displayed from the PC. Another scheme has been adopted in DHRUVA where five computers in a local area network provide on-line and off-line information to plant personnel. 

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. 

In one inspection performed at a plant right after 9/11, we drove up to the entrance gate and were impressed with the height and condition of the razor wire-topped fence and gates. We could not enter through the gates until we identified ourselves over a speaker system while a CCTV camera focused on my face. We were let in and given... 

CCTV technology is used to analyze digital images and identify the characteristics of a fire. CCTV can provide both a control action and display the picture in a staffed control room. The latter has a particular benefit as it allows very rapid incident assessment and also reduces the need for personnel to enter the area to investigate the fire conditions. In general terms, the CCTV flame detection system is comprised of three basic components the camera/detection element, the control panel, and the display computers. 

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. 

Closed circuit TV (CCTV) cameras (color or black-and-white) for furnace systems are usually industrial surveillance types (typically 540-line high-resolution). These transmit the images of combustion to normal industrial-type monitors, which may be in a control room or locally at the viewing site. The process can also be digitally recorded for further evaluation.

Here, we show only a bare outline of the individual components in the overall system. This SYSTEM is capable of operation in inert atmosphere or vacuum. A melt/seed contact monitor is provided as well as a CCTV camera for observing and controlling the crystal diameter as it grows. Note that both the crucible and crystal rotation can be controlled. In order to control the heat-convection patterns which normally appear in the melt, an external cryomagnet is supplied. Its magnetic field controls heat losses, plus it maintains a better control of the crystal growth. A slave micro-processor controls both crystal diameter and meniscus-contact of the growing crystal. 

Six-lead ECG measurement in the conscious dog Conscious studies using integrated telemetry systems devices for measurement of blood pressure and six chest lead ECG measurements (V2, V4, V6, VIO, rV2, and rV4) can be routinely performed. ECG interval analysis is performed on the V2 lead (RR, PR, QT, QTc intervals, QRS duration). QT dispersion can also be measured. Locomotor activity can be monitored and behavior captured on video using CCTV. 

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. 

A permanent record of the CCTV pictures can be stored and replayed by incorporating a video tape recorder into the system as is the practice in most banks and building societies. 

Cinematography also has important applications in the security industry. Both private security firms and public agencies make use of closed-circuit television (CCTV) technology—a system in which the video imaging signals from one or more cameras are transmitted to a restricted set of monitors—to keep a continuous record of what takes place in businesses such as banks, convenience markets, and hospitals, and public areas with a high record of criminal activity.
