Personal Digital Hub

What will please you, these watches: Color lcd display with a diagonal 3.6 cm – a full-screen resolution of 128 x 128 pixels and 65000 colors. Enough for viewing video files. Internal memory 2 gigabytes – enough for several movies or more than 400 favorite songs. In addition it can store any other files, and always have them with me. Built-in Mini-USB – via his clock connected to a computer to upload information or recharging.

Battery-Battery – up to 5 hours. Music – listen to music in the formats of MP3 (up to 320kbps) and wma (up to 380kbps). This is the most common music file formats. To read more click here: Republic Services. In addition to the hours supports ID3 – it allows you to view lyrics with the appropriate files. Equalizer – 6 modes available: normal, rock, pop, jazz, classic, super-bass.

Choose the music you're listening to. Video – now on a plane, subway or on the boring lecture you can watch video files. Hours support the format smv. In this format you can easily convert files to mpeg, avi and wmv using a program that comes with the kit. Pictures – hours can be carried and at any time to view the collection of photographs and other images. You can watch them manual mode switch, a slide show or as icons. Electronic books – clocks allow you to read electronic books in a format txt – pump up more such books from the Internet and read at any time. Recorder – Dream spy – recorder is always with you. Turn on and record any talks or lectures of professor. Date and time – of course clock shows the date and time – it's a clock!

Night Vision LED

Lighting system in the photos and videos in video surveillance system is essential. Many of diffractive optical devices without additional lighting give a very low quality. A highlight in his turn may increase or decrease the characteristics of the observed objects. Low light object can even lead to a false image. All these problems can be avoided by careful application of additional lighting. When calculating the lighting systems are accepted parameters such photo and video cameras like: aperture optical system, the sensitivity of the camera, light spectrum, intensity, etc. Comparison of led and conventional light sources. A.

Spectrum by the spectral composition of traditional halogen light sources like blackbody radiation. Efficiency of halogen lamps so low and declining due to optical komponentov.Diody same are semiconductor devices that convert electricity directly into light. The effectiveness of radiation in this case is very high, because radiation in the visible spectrum. B. Lifetime Hours Some ordinary light is less than 40 hours. Of course, the greater reliability of LEDs give the running time is over 100000 hours, ie 11 years of continuous operation. However, it is necessary to take temperature range devices. C.

Mechanical stability of LEDs mechanically very stable. Because design of the diode consists of optical fibers by mechanical damage diode is out of work. Well, unless the hammer is not hitting. Such resistance of diodes allows them to use as a light source attached to any moving parts. But, by itself, an optical fiber is not as mechanical fortitude. Therefore, in the bumps and bruises all the same is likely to reduce the light intensity. We offer a large selection of miniature video cameras, including camera with Night Vision LED-backlit display. Cameras in motion sensors and recording on an sd card. Wireless and wired models of street cameras and cameras for home use.
