With the continuous advancement and widespread adoption of network technologies and applications, the growth of the network video surveillance industry has been truly remarkable. Among the various solutions, optical network cameras have gained significant popularity among users due to their superior performance and reliability. Our company has introduced the 80-meter infrared fiber optic network camera, which offers several advantages over traditional twisted-pair network cameras in practical applications. First, it provides a much longer transmission distance. Traditional Category 5 or Category 6 twisted-pair cables typically support a maximum transmission range of 100 meters. Beyond that, additional equipment such as switches, hubs, or signal amplifiers is required. In contrast, our TSD802-3S42-80F fiber optic network camera uses single-mode fiber, allowing for stable transmission over distances of up to 30 kilometers without the need for extra repeaters. Second, it features strong resistance to interference. Twisted-pair network cameras use copper cables, which are susceptible to external electromagnetic interference from sources like lighting systems, industrial power lines, and even lightning strikes. On the other hand, fiber optic cables are non-conductive, making them nearly immune to environmental disturbances, ensuring clearer and more reliable video signals. Third, it experiences minimal signal attenuation. The TSD802-3S42-80F uses fiber optics for data transmission, which significantly reduces signal loss compared to traditional copper-based systems. This ensures high-quality video quality over long distances. As major telecom operators continue to invest heavily in network infrastructure, especially in fiber-to-the-home projects, we believe that the TSD802-3S42-80F will become a standout product in the market, offering unmatched performance and value for both residential and commercial applications.
