Hertz (hz)
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
- The number of variations per second (e.g. picture frames, alternating of the current, etc).
- Unit of frequency in the international system of units (si), abbreviated hz; replaces cps for cycles per second.
- Unit of measurement for frequency, equal to cycles per second—see ac (alternating current). common household mains power is normally 50hz, or 50 cycles per second. horizontal-axis wind turbine: the most common form of wind turbine, consisting of two or three (but up to six or more in some designs) airfoil-style blades attached to a central hub which drives a generator. the axis, or main shaft of the machine is horizontal, or parallel to the earth’s surface. i

Hertz, английский
- The unit of measurement for frequency in a signal. 1 hertz = 1 cycle per second.
- Hertz is often referred to as "cycles per second". in the united states, the frequency or directional change of alternating current is usually 60 hertz.
- (abbrev. h) a term rapidly replacing cyclespersecond as an indication of frequency.
- The unit which expresses cycle frequency.
- A measure of frequency; one hertz equals one cycle per second; 60 cycle a.c. is 60 hertz a.c.
- An unit that measures the number of certain oscillations per second.
- H
- An unit that measures the number of certain oscillations per second. housings, environmental. usually refers to cameras’ and lenses containers and associated accessories, such as heaters, washers and wipers, to meet specific environmental conditions.
- A unit of frequency equal to one cycle per second.
- A unit of frequency, abbr. hz; one cycle per second.
- Герц; гц (единица частоты периодического процесса)
- Vibrations or cycles per second, abbreviated `hz`, a measurement of the frequency of a vibrating object. if you play the open a string on a concert-tuned guitar, the string`s tone is at 110hz, which is 110 vibrations per second. the human range of frequency perception, on average, is roughly 20 hz to 20,000 hz.
- A cycle or oscillation per second. a second hand on a standard analog clock ticks at 1 hertz. the clock on most computers is currently on the order of 1 gigahertz.
- One cycle per second; a unit for frequency. abbreviation is hz.

Hertz, французский
Unité de mesure de la fréquence des sons. Ça correspond au nombre de cycles par seconde d'une onde sonore. l'oreille humaine est sensible aux sons variant approximativement de 20 hertz (son très grave) à 20 000
Hertz contact stress, английский
Stress (psi) measured along a narrow band of contact between two gear teeth under load; based on formulas devised by hertz. momentary stresses exceeding 200,000 psi are not uncommon in heavily loaded gears. also may occur at contact points in rolling element bearings.
Hertz horn, английский
The upper half of a naval contact mine is studded with hollow lead protuberances called hertz horns. when a ship’s hull hits one of these horns, its lead casing is crushed, cracking a glass vial filled with sulfuric acid. the acid runs down a tube into an empty lead-acid battery, forming the electrolyte and energizing the battery, which detonates the explosive.
Hertzian radiation, английский
Электромагнитное излучение
Hertzian radiator, английский
Электромагнитный излучатель
Alternating, английский
- Current, synchronous на переменном токе, синхронный
- Current, volt напряжение переменного тока в вольтах
- Flemish bond a brickwork pattern which is produced by laying alternate
- Переменный; знакопеременный; альтернативный
- Знакопеременный (о силе, напряжении)`, чередующийся
International, английский
- Международный
- A интернацио- нальный; pseudo~ псевдоинтернациональный alphabet, language
- Профсоюз, имеющий первичные организации более чем в одной стране int – ist

Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a

Internet protocol (ip), английский
- The primary communications protocol in the internet protocol suite for sending and receiving data packets across network boundaries.
- A set of rules for how data is transmitted from place to place on the internet. ip is a connectionless protocol in which data is broken down into small bundles known as packets. each packet is transmitted separately, possibly along a different route than other packets from the same message
- Standard packet-switched transmission format for the internet; uses variable-length packets.
Switchbox, английский
- The first-of-its-kind switchbox nvr delivers an ip network recording solution—without the complexity. the switchbox nvr features an integrated 4 or 8-port poe (power over ethernet) network switch to power the ip network cameras directly through the network cable—eliminating the need to purchase a separate network switch. the all-in-one switchbox nvr delivers an easy-to-install, plug-and-play ip- based recording solution.
- Распределительная коробка
