[Air@-EL100] What is the LED optical video transmitter?

A LED optical video transmitter is a device that transmits video data using modulated LED light in a fashion similar to fiber optic communications. This allows high speed and high quality(DVD resolution) wireless transmission at full wire-line data rates. In addition, the LED light is very safe to the eyes because the same LED as normal LED light is used.

[All] Do the products affect the elevator safety?

No, they do not affect the elevator safety at all because they do not produce any electromagnetic waves.
During the operation, they are even safer to the elevators because they do not need the heavy coaxial cable and have no influence on Power cable and Traveling cable.

[All] What happens if dust accumulates on the receiver lens?

Wavelength of the LED(or laser) light passes through the dust in some degree, and it will not affect the video transmission. According to our domestic experience over 9 years, dust had no influence on the video quality at all. However, it can be affected if the particles of dust are very thick or if greasy. Therefore, it is recommended to clean the lens during the safety inspection or every 2~3 year. When you carry out the safety inspection, please brush away the dust on the lens by using a camera lens cleaning brush, and do not move the receiver or the transmitter body.

[All] How about the installation? Is it difficult?

The installation is not so difficult than you expect. We provide our installation video clips, user manuals and alignment instructions to our clients. If they follow the manuals thoroughly, they can install our products easily. After they install once or twice, they become specialists about the installation. Our all overseas customers install our products easily even when they install our products at the first time. Regarding this, please refer to the Alignment Instructions on the Support(Download) page.


 
[All] What kind of certificates did the products obtain?

In case of Air@-EL100 based on safe LED technology, we got CE, FCC certificates. In case of Air@-EL300, we have already obtained CE, FCC, IEC-60825-1:2007(2nd Edition) and FDA's CDRH for Laser Safety. Especially, Air@-EL300 complies with FDA performance standards 1040.10 for laser products.

[All] Are the products made in Korea?

Of coures. The main bodies of our products are made in Korea. They are manufactured under the process of stringent Quality Control. As our company name, Qccess, is derived from 'Quick access and Quality access', we are confident in the quality of our products.

 
[Air@-EL150, Air@-EL300] What is the laser optical video transmitter?

A laser optical video transmitter is a device that transmits video data using modulated laser light in a fashion similar to fiber optic communications. This allows ultra-high speed and high quality(DVD resolution) wireless transmission at full wire-line data rates. In addition, the laser beam makes it the most secure means of wireless communication.

[Air@-EL150, Air@-EL300] Is the laser safe?

Air@-EL150 and Air@-EL300 are rated as a Class 2 laser. The laser light of Air@-EL150 and Air@-EL300 is considered safe even if viewed with the naked eye at the point of transmission. The laser beam spreads out by the time it reaches the receiving side, making it even safer there than it is on the transmitting side. However, it is not recommended to use magnifying optics such as binoculars at the point of output, as the effect on the eyes would be amplified. We also caution not to stare at the laser light directly when the device is on.

[Air@-EL150, Air@-EL300] Do Air@-EL150 and Air@-EL300 work well in high-rise buildings?

No problem. When you aligned the receiver to transmitter, you can see the red circle on the receiver lens. This circle's diameter will increase when the transmitter moves back from the receiver. So in case of long distance, signal reception area is getting bigger and bigger. That's why our products work well even in high-rise buildings. To watch it, please see the installation video clip on our website.

[All] Is the performance of the system affected by the weather condition?

Weather conditions can affect an optical beam. Rain, fog or snow reduces visibility, scattering and attenuating the amount of LED(or laser) light that passes between the transmitter and the receiver. However, under normal conditions, these conditions should not occur within an elevator hoistway.

[All] What happens if something such as a bird comes across the LED(or laser) path between the transmitter and the receiver?

If something comes across the path of the LED(or laser), the transmission can be interrupted for a very short time. However, under normal conditions, these conditions should not occur within an elevator hoistway.
