The dome camera is one most commonly used for indoor and outdoor security and surveillance. The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty.
A C-mount is a type of lens mount commonly found on 16 mm movie cameras, closed-circuit television cameras, machine vision cameras and microscope phototubes. C-mount lenses provide a male thread, which mates with a female thread on the camera. The flange focal distance is 17.526 millimeters (0.6900 in) for a C mount.
PTZ stands for Pan, Tilt and Zoom. A surveillance camera with PTZ functionality features a rotating lens with directional and zoom capabilities, and the camera can be controlled remotely; It can pan left to right and tilt up and down. The lens also zooms in and pulls out, providing imagery at various distances.
An IP camera, or Internet protocol camera, is a type of digital security camera that receives and sends video footage via an IP network. They are commonly used for surveillance. Unlike analog closed-circuit television cameras (CCTV), IP cameras do not require a local recording device, only a local network.
Time and attendance systems (TNA) are used to track and monitor when employees start and stop work. A time and attendance system enables an employer to monitor their employees working hours and late arrivals, early departures, time taken on breaks and absenteeism.
Proximity readers are a popular choice for many access control systems. But what is a proximity card reader, and why would you want one? In terms of access control, a door access reader is the first security measure people encounter when trying to enter a space. In order to gain entry with a proximity card reader, the user needs to have an authorized proximity card on their person. Proximity cards and readers use RFID (radio frequency identification) to communicate wirelessly, with authorization data encoded on the cards.
Proximity readers are a great option for commercial building security, as they can be programmed to meet a wide variety of needs. Before installing an access control system with proximity card readers in your space, it’s important to understand the different types of readers available, and the potential benefits and drawbacks of a proximity card reader system.
The software scans the finger for identification. It does not store a copy of the fingerprints. Instead, the software creates a template of the unique fingerprint characteristics. These templates are stored in the school's database with the same high level of security of all of your child's records.
A retinal scan is a biometric technique that maps the unique patterns of a person’s retina using a low-intensity light source. Through a delicate sensor, a retinal scan examines the pattern of retina blood vessels, which remains unchanged from birth till life ends.
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have two main classifications of operation, "rate-of-rise" and "fixed temperature". The heat detector is used to help in the reduction of property damage.
fire alarm control panel (FACP), fire alarm control unit (FACU), fire indicator panel (FIP), or simply fire alarm panel is the controlling component of a fire alarm system. The panel receives information from devices designed to detect and report fires, monitors their operational integrity, and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also supply electrical energy to operate any associated initiating device, notification appliance, control, transmitter, or relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems.
Manual fire alarm activation is the process of triggering a fire alarm through a call point, pull station, or other device. This usually causes the alarm to sound the evacuation signal for the relevant building or zone. Manual fire alarm activation requires human intervention, as distinct from automatic fire alarm activation such as that provided through the use of heat detectors and smoke detectors. It is, however, possible for call points/pull stations to be used in conjunction with automatic detection as part of the overall fire detection and alarm system.
A smoke detector is a device that senses smoke, typically as an indicator of fire. Smoke detectors are usually housed in plastic enclosures, typically shaped like a disk about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary. Smoke can be detected either optically (photoelectric) or by physical process (ionization). Detectors may use one or both sensing methods. Sensitive alarms can be used to detect and deter smoking in banned areas. Smoke detectors in large commercial and industrial buildings are usually connected to a central fire alarm system.
There are various technologies for an automatic boom barrier. One of them is electro-mechanical, which is widely used due to its reliability. The other technologies are often manufacturer specific. These electro-mechanical devices come with 24-volt direct-current drive units which can run continuously without generating heat, so electro-mechanical boom barriers can be operated continuously and in an intensive duty cycle. USAGE: Boom gates are typically found at level crossings, drawbridges, parking facilities, checkpoints and entrances to restricted areas. They are also the usual method for controlling passage through toll booths, and can also be found on some freeway entrance ramps.
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control.
Bollards have become common use for reserving parking spots from unauthorized vehicles. Parking bollards are typically situated in the centre of a parking bay as a physical obstruction. They then fold either manually or automatically to admit authorized users. These bollards are often used in smaller parking lots such as visitor parking or corporate parking lots, as an alternative to boom gates. They can be powered by a wide variety of means, with the most common being battery-powered or electric-powered.
A turnstile (also called a turnpike, gateline, baffle gate, automated gate, turn gate in some regions) is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, pass, or other method of payment or verification. Modern turnstiles can incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned. Thus a turnstile can be used in the case of paid access (sometimes called a faregate or ticket barrier when used for this purpose), for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.
A microphone is a device that translates sound vibrations in the air into electronic signals and scribes them to a recording medium or over a loudspeaker.
Microphones enable many types of audio recording devices for purposes including communications of many kinds, as well as music vocals, speech and sound recording.
Microphones can be standalone or embedded in devices such as headsets and telephones.
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). A power amplifier is similarly used to deliver output power (AF or RF), controlled by an input signal. It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is a circuit that has a power gain greater than one.
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A speaker system, also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker drivers, an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal.
It is used in malls, halls, stations, airports, etc. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. The system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution.
Demarcation of a perimeter, when the protection of assets, personnel or buildings is required, is normally affected by the building of a perimeter fence system. The level of protection offered varies according to the threat level to the perimeter. Types-
An electric fence is a barrier that uses electric shocks to deter people and/or other animals from crossing a boundary. The voltage of the shock may have effects ranging from discomfort to death. Most electric fences are used for agricultural fencing and other forms of non-human animal control, although they are also used to protect high-security areas such as military installations or prisons, where potentially-lethal voltages may be used. Virtual electric fences for livestock using GPS technology have also been developed.
Active infrared barriers are composed of :
