It is the safety and reliability requirements of using cell phone jammer .
Unlike optical zoom, digital zoom is up changes in the vertical direction of the photosensitive device, while giving effect to zoom. The smaller area of the photosensitive device, then the vision will allow users to only see the local scenery. However, due to the focal length does not change the image quality is relative to the poor under normal circumstances. Digital zoom, shooting the scene enlarged, but its definition will have decreased to some extent, the digital zoom does not have much practical significance. Too much digital zoom makes image severely damaged, and sometimes because the magnification is too high, and can not tell the footage. cell phone jammer meet the related industry standard.The material is no good for the heat dissipation of the host of cell phone jammer
Early stages of development in computer technology, data, cable transmission, cable transmission connection trouble, need special interface, which is quite inconvenient. So then there is the infrared, Bluetooth, 802.11 wireless data transmission technology. Early stages of development in the infrared communication technology, there are several infrared communication standard, the infrared device is not between the different standards for infrared communication. In order to make a variety of infrared devices to interoperability, and 1993, more than 20 companies such as HP, COMPAQ, INTEL, initiated the establishment of the Infrared Data Association (Infrared Data Association or IrDA), a unified standard for infrared communications, this is IrDA infrared data communication protocol is widely used and standardized. It is the installation procedure and method of cell phone jammer .
Infrared electromagnetic waves of wavelengths between 750nm to 1mm, its frequency is higher than the microwave lower than that of visible light, a human eye can not see the light. Due to the shorter wavelength of the infrared obstacle diffraction poor, so more suitable for application in situations that require short-range wireless communication, point-to-point straight-line data transmission. Infrared Data Association (IRDA) to limit the scope of the wavelength of light used by the infrared data communication within the 850nm to 900nm. IrDA certification mark. Infrared interface is the configuration of a new generation of mobile phone standards, it supports the phone and computer and other digital devices for data exchange. Infrared communication has low-cost, easy connection, easy to use and compact structure. And the host of cell phone jammer will start working.
Therefore widely used in mobile devices. Through the infrared interface, the various types of mobile devices can be free to exchange data. Of course, the infrared technology also exists a large drawback: the communication distance is short, the process of communication can not be moved, the case of obstacles breakdown in communications; infrared communications technology intended to replace the cable connection for wireless data transmission, single function, poor scalability. Principles and applications of Bluetooth technology Bluetooth (Bluetooth) technology was first used by five world-class companies such as Ericsson, IBM, Intel, Nokia and Toshiba jointly launched a short-range wireless communication, global standards, then there Lucent, the Microsoft Motorola and 3Com and three other companies to join. The valid shielding range of cell phone jammer should be a round area centered at the jammer.

The groups of application of green laser pointer
The groups of application of green laser pointer
2. Level 2 measures for the safe use of lasers
Level 2 for the low-level laser laser, such as occasional exposure to the human eye is not the cause of the injury, when the continuous observation of the laser beam can damage the eyes. Thus, not long. The laser beam between right into this second-level laser is the most important control measures.You can even look at the first-level laser of green laser pointer directly for it would never harm you. In addition, the first two should be placed on the laser and the laser enclosure door and put a warning tag on the control panel.
3. Level 3 security measures to use lasers
As the No. 3 laser is a medium-power lasers, may have eye damage, the laser must be set to this level measures to ensure safety:
(1) laser operating staff education and training so that he (she) who understand the operation of this laser level may occur when the potential danger, and he (she) had the appropriate laser safety training, and in danger emergency treatment. The second-level laser or low power laser of green laser pointer does no heat injury to skin.As the laser damage to the eyes are not reversible, training and education to understand and master the use of laser safety is necessary.
Management and use of lasers must be professional (staff) personnel to carry out, without the training and education personnel are not allowed to turn a laser machine. If the trigger on the laser interlock key switch installed on the system, ensure that only with a key to open the interlock switch to trigger after the start, pull out the key will not start. The medium power laser of green laser pointer has no harm to skin of human bodies.Should be placed in the room for the bright laser light, bright light in the environment, the eye miosis, prevent the laser beam can be injected into the eye to reduce the transmission amount of light on the retina. For highly placed laser, the laser beam path should avoid standing or sitting when the normal horizontal position of the eyes, the visual axis is not parallel with the optical port on the TV.
The use of lasers in the store room not without cause the body to the laser beam alignment, especially the eyes. The four-level laser of green laser pointer hurts skin hardly.Because the laser damage to the eyes is extremely difficult to restore, both permanent damage, but also each individual's life, only a pair of eyes, we must always keep in mind before starting laser, be advised that on-site hazards may occur in people, and wear on safety glasses. In a strong laser inside and outside the work area clear position and the laser operating room, laboratory risk marker is posted on the door.
Level 3 laser must only be used within a certain area of laser equipment. The four-level laser of green laser pointer is very dangerous.General requirements established by the spring guard and safety lock, interlock, so as to ensure that outsiders and unprotected personnel shall not enter the controlled area, even if the accident door was opened, the laser excitation can be stopped immediately.
2. Level 2 measures for the safe use of lasers
Level 2 for the low-level laser laser, such as occasional exposure to the human eye is not the cause of the injury, when the continuous observation of the laser beam can damage the eyes. Thus, not long. The laser beam between right into this second-level laser is the most important control measures.You can even look at the first-level laser of green laser pointer directly for it would never harm you. In addition, the first two should be placed on the laser and the laser enclosure door and put a warning tag on the control panel.
3. Level 3 security measures to use lasers
As the No. 3 laser is a medium-power lasers, may have eye damage, the laser must be set to this level measures to ensure safety:
(1) laser operating staff education and training so that he (she) who understand the operation of this laser level may occur when the potential danger, and he (she) had the appropriate laser safety training, and in danger emergency treatment. The second-level laser or low power laser of green laser pointer does no heat injury to skin.As the laser damage to the eyes are not reversible, training and education to understand and master the use of laser safety is necessary.
Management and use of lasers must be professional (staff) personnel to carry out, without the training and education personnel are not allowed to turn a laser machine. If the trigger on the laser interlock key switch installed on the system, ensure that only with a key to open the interlock switch to trigger after the start, pull out the key will not start. The medium power laser of green laser pointer has no harm to skin of human bodies.Should be placed in the room for the bright laser light, bright light in the environment, the eye miosis, prevent the laser beam can be injected into the eye to reduce the transmission amount of light on the retina. For highly placed laser, the laser beam path should avoid standing or sitting when the normal horizontal position of the eyes, the visual axis is not parallel with the optical port on the TV.
The use of lasers in the store room not without cause the body to the laser beam alignment, especially the eyes. The four-level laser of green laser pointer hurts skin hardly.Because the laser damage to the eyes is extremely difficult to restore, both permanent damage, but also each individual's life, only a pair of eyes, we must always keep in mind before starting laser, be advised that on-site hazards may occur in people, and wear on safety glasses. In a strong laser inside and outside the work area clear position and the laser operating room, laboratory risk marker is posted on the door.
