CCTV – Closed Circuit Television: definition and explanations

CCTV means Closed-circuit television or video surveillance, ie the use of video surveillance cameras to transmit a signal to a certain location on a limited number of monitors.

We are talking about the idea of “closed-circuit television”, a notion different from classical television, because the transmitted signal is not a public but private, limited. Who? Some people who have the necessary access data, that is username and password. Where is it used? CCTV is used in video surveillance activities of certain locations, starting with homes (houses or apartments), buildings, office spaces, different commercial or industrial spaces, banking or military units, car parks of small or large size, casinos, Schools, public areas and areas with intense road traffic and so on. This type of video surveillance can also be used for other purposes, such as supervising children, employees, or for preventing and detecting offenses. 4K CCTV installation in London.Closed Circuit Television

History of video surveillance cameras

The history of surveillance cameras is extremely complex and begins long before people know about their existence. It is said that the first real video surveillance camera was due to the British and a certain lord Norbury in London. At his origins, a mere farmer, Norbury seems to be the first amateur photographer in history to put his watch on a surveillance camera.

From what was his camera formed? It was a simple face-down camera that was meant to oversee a hen’s nest. Using a sack, a metal tube and a wire, the room started as soon as possible as he tried to steal Norbury’s chickens. It was all in 1933 !! But the development of the industry has gained momentum in the decades to come. Somewhere around 1965, the first activity reports had already appeared suggesting that the New York metropolitan police were using surveillance cameras to monitor certain public places considered to be at high risk. Four years later, officially, the police are already installing surveillance cameras in the New York City Muncipal Building, near the Town Hall. This practice of New York Police has spread rapidly to other US cities, and the authorities have just as much to gain as people.

Rapidly, metropolitan police in many major cities in the United States raised the level of security on the streets and created new jobs, employing people to oversee these cameras implanted in a CCTV system. But what needs to be emphasized is that the first real video surveillance system with such cameras had been installed according to confirmations 23 years ago! At Peenemunde in Germany, the Siempens AG corporation intended to track the launch of the V-2 rocket so it turned to the skill and imagination of the famous German engineer, Walter Bruch. He accomplished his goal and received praise. In the US, four years later, 16 years before the New York police installed their own camcorders, a first Vericon video surveillance system was launched.

When video recordings appeared on the market, video surveillance really took steps forward. Analog technology used still the old VHS cassettes, which meant that the recordings could not be stored in an advantageous manner. The emergence of dvrs has solved this detail, and surveillance cameras have become mandatory in the context that surveillance systems increased as sales and the rate of crime was obviously decreasing. The 1970s brought a real explosion in this sector, England installing security systems in four major train stations in the country. In the United States in the 1980s, most of the shops and public areas were covered by surveillance cameras, and businesses, gas stations and banks that were prone to robbery became much safer locations. In the 1990s, women became more and more independent and forced to leave their children unattended. There have been other new jobs through the appearance on the market of “bonuses” or baby-sitters. In order to control them, families were calling for hidden surveillance cameras, the so-called “nanny cams,” which gave them the control they needed to watch not only the child left behind but also the caregiver. In 1990, Dycam introduced the first digital camera model and made it known to the public, for 5 years later, the Ricoh RDC-1 is the first video camera capable of making movies. In the years 2000, Nikon’s became the first manufacturer in the world to bring Digital Single Lens Reflex video surveillance cameras to DSLR. Nikon’s D1 camera could operate at 2.74 megapixels and was a real shot in the field.

The best above the ground swimming pools

The affordable alternative for inground swimming pools are the steel swimming pools – above the ground, easy to build, low maintenance and much less expensive, this is the modern solution. While it can come in prefabricated sections, ready to be installed upon arrival, they can still take any shape and size you may desire.

Of course, the question is may ask is why should you make such a purchase right now, in the cold season? And the answer is within the question: because it is the cold season, we can offer you several types of discounts for your purchases. Then you should also take into account that the swimming pools are always overpriced during the hot season – so, if you want to make an affordable investment, now is the time to do it. With the first day of the hot season, this investment will pay off.

And you don’t even have to wait until then – the steel swimming pools can also be installed inside the house itself. In such cases, you should take into consideration first and foremost the size of the swimming pool. Only afterwards you should consider the shape of the pool and all the other extra features.

Speaking of which, just like a proper inground swimming pool, this type of above the ground swimming pool can also support several extra-features. In this way, your purchase can also include a heating system, which will keep the water at the desired temperature. For the indoor pools, you may consider a dehumidifier system, which will regulate the humidity and temperature in the room, thus decreasing the costs. A water circulation system is always needed, especially if you plan on installing some other systems (such as the ones mentioned above).

Chic and cool, these types of swimming pools are the latest trend – and they are much cheaper than the traditional inground ones, while also being a way better alternative to the inflatable ones.

As their name suggest, the base material used for their construction is stainless steel – which is used for the walls, for the steps, and for the sturdy support buttresses. However, the steel swimming pools also use PVC, for waterproofing and reducing to a minimum the water infiltration, as well as (at the customer’s choice) smooth concrete slabs.

The stainless steel is the best material for any kind of swimming pool, since it is safe and clean and since it is very resilient. In this way, it is resistant to all sorts of weather hazards, such as extreme cold and heat.

For protection and safety, we also recommend installing shutters. In this way, you will save both the energy required for heating the water and you will also keep the water clean and clear (so no leafs or bugs or other types of impurities).

Of course, there are also some other types of extra-features which can be added – and for those we will also offer you discounts. So leave aside the thought of purchasing the expensive inground swimming pools and go for the more affordable, yet still elegant, solution.

Call us now and have our professional teams of technicians tell your all about our special offers for steel swimming pools. Benefit from our discounts and you will see that this was the best investment to be made.
