What is one of the transmission methods used for VSS?

The correct answer highlights cellular transmission as one of the methods used for VSS (Video Surveillance Systems). Cellular networks are crucial for transmitting video data, especially in environments where traditional wired connections might be impractical or impossible. They allow for flexible deployment and can provide coverage in remote or hard-to-reach areas.

Cellular technology is particularly advantageous because it offers a broad geographical coverage, enabling real-time video streaming and communication, which is essential for effective surveillance operations. The ability to utilize existing cellular infrastructure means that VSS can be set up quickly without the need for extensive cabling, making it a popular choice for temporary or permanent installations.

Other methods such as optical fiber, satellite, and twisted pair also serve purposes in data transmission but come with their own limitations regarding mobility, infrastructure requirements, and deployment speed. Optical fiber, for example, offers high bandwidth but is less flexible when it comes to rapid deployment in varied environments. Satellite transmission, while capable of covering vast areas, can suffer from latency issues. Twisted pair cabling is typically limited to short distances and requires significant infrastructure investment. Thus, the cellular transmission method stands out for its convenience and adaptability in the context of video surveillance.
