FM modulation:
KP-500 TX 2W adopts FM modulation technology. Compared with traditional AM modulation, KP-500TX2W has stronger anti-interference ability and ensures the stability of transmission.
FM(Frequency Modulation (FM) and amplitude modulation (AM) are two basic modulation methods, which have their own characteristics. FM modulation technology transmits information by changing the frequency of carrier signal, while AM transmits information by changing the amplitude of carrier signal.
The main advantages of FM modulation include: Strong anti-interference ability: FM signal has strong resistance to noise and interference, because noise usually does not change the frequency of carrier, only the frequency change of signal can be detected by receiver.
High stability: Because the frequency change of FM signal represents information, even if the signal is disturbed to a certain extent during transmission, as long as the frequency change can be accurately identified, the information can be correctly received, thus ensuring the stability of transmission.
Strong anti-fading ability: FM modulation technology is insensitive to the fast fading of signals (such as the rapid change of signal strength caused by multipath propagation), which makes it still maintain good communication quality in the changeable transmission environment.
In contrast, the disadvantages of AM modulation include: Weak anti-interference ability: the amplitude change of AM signal is easily concealed by noise, which leads to the decline of reception quality. Low power utilization ratio: AM signals need large power during transmission to ensure that the amplitude changes of signals can be accurately received.
Therefore, KP-500 TX 2W equipment with FM modulation technology is superior to equipment with AM modulation in anti-jamming ability and transmission stability, especially in wireless communication environment where signals may be interfered.
Brand-new frequency band:
The equipment uses a brand-new transmission frequency band, which avoids common interference sources, such as Wi-Fi and Bluetooth, and greatly improves the transmission quality.
High sensitivity:
KP-500 TX 2W is equipped with a high sensitivity receiver, which can maintain the continuity and stability of video transmission even in a weak signal environment.
Long-distance transmission:
Under ideal conditions, the ground transmitting antenna of KP-500 TX 2W can cover the transmission range of 1-2 kilometers. Under air-to-ground conditions, the transmission distance is longer, up to 20 kilometers.
Durability:
the equipment is made of special metal, which ensures the stability and durability of long-term work. Efficient heat dissipation: the equipped high-speed fan can effectively dissipate heat, ensuring the performance stability of the equipment under long-term continuous work.
Universal AV interface:
KP500TX2W supports universal AV interface, which enables the equipment to be easily connected with various cameras, players and other equipment for expansion.
This feature of KP500TX2W equipment allows users to easily connect it to a wide range of audio and video sources, such as cameras, media players, game machines and so on. This universality means that users don't have to worry about compatibility, because AV interface is a widely accepted and used standard interface, which is supported by almost all modern audio and video equipment. This provides great convenience and flexibility for users. Whether it is for home entertainment, professional video production or the construction of monitoring system, KP500TX2W can be competent, thus meeting the connection requirements in different scenarios.
Wide applicability:
The equipment is widely used in various scenes such as wireless CCTV system, FPV system, unmanned aerial vehicle, airplane model, unmanned vehicle, etc., and has strong universality and adaptability.
Customized service:
KP-500 TX 2W can customize the data transmission function according to the special needs of users and provide more flexible solutions. conclusion KP-500 TX 2W wireless video transmission equipment has become an ideal choice for various high-quality video transmission applications because of its unique FM modulation technology, brand-new frequency band selection, high-sensitivity receiver, long-distance transmission capability, excellent durability and heat dissipation design, wide applicability and customized data transmission function.
