The main feature of any IP camera is its electronic filling. Depending on the cost of the device, it may have different additional functionality. For example, there are models that have a night mode – they do not need to turn on the light in the room. There are also IP cameras that can be accessed from absolutely any other gadget – in particular, from a smartphone. In a word, if you do not regret money and get the best model, you will sleep peacefully, as your store, bank or some other object will be reliably protected.
Corum CCTV was founded recently. For a short period of existence, she managed to make herself a big name. Now Corum IP video cameras are installed in retail outlets and premises of any type.
Buyers are not confused by the relatively low cost of such devices – it is much more important that the cameras stably perform their task. Many models produced by Corum have a waterproof housing, which allows them to be installed even on the street, attaching to the facade of the building. Continue reading
With the development of digital photographic equipment, two main trends are steadily observed – an abrupt increase in the resolution of CCDs and a gradual decrease in prices in each of the categories of cameras. However, there are a number of market niches in which the price remains the same, but at the same time there is a constant qualitative improvement in cameras. By “quality improvement” we should understand not only the increase in sensor resolution, but also the improvement of lenses, ergonomics, a set of service functions – in short, all that allows you to get good pictures without extra effort on the part of the user. In one of these market niches can be attributed cameras, the cost of which ranges from 200 to 300 $. In the second half of the nineties of the last century, for the amount mentioned, it was possible to purchase a product of a little-known brand from Southeast Asia, equipped with a plastic similarity to the lens and a CMOS sensor with a resolution of less than a megapixel, moreover, the manufacturer often considered the flash and LCD display to be an excess and did not equip their products.

The history of Polaroid began in 1922 at the Mouven Summer Camp for Boys, which was located on a lake in Connecticut. Barney Griden worked as a mentor in the camp, he was passionate about physics and later patented eight inventions for scuba diving.
Barney demonstrated scientific experiments to teenagers, woke them in the middle of the night to show a thunderstorm and explain its nature. Seen experiments so influenced his students that in the future many of them took up science.
The most famous among those students was Edwin Land, he patented 535 inventions – only Thomas Edison received more patents. Land’s inventions include a polarizer, an X-ray film, 3D films, night vision devices for the army, and much more. The scientist led the development of the U2 spy plane when he was an adviser to U.S. President Dwight Continue reading
