Live streaming is an essential feature of which type of device mentioned?

Live streaming is an essential feature of surveillance cameras because these devices are designed to capture real-time video footage and transmit it over the internet. This capability allows users to monitor events as they happen, making surveillance cameras ideal for security purposes in both residential and commercial settings.

Surveillance cameras often come equipped with streaming technology that supports various protocols, enabling users to access live feeds from their devices, whether through dedicated applications or web interfaces. This functionality is critical for situations where immediate viewing and response are necessary, such as monitoring high-traffic areas or identifying potential security threats.

While encoders are also involved in processing video signals for streaming, their primary role is to convert the video into a suitable format for live transmission. Decoders, on the other hand, are used to interpret and display the streamed content. Networking cables facilitate the connection and transfer of data, but they do not directly provide live streaming capabilities. Therefore, among the options provided, surveillance cameras are unequivocally recognized for their dedicated live streaming functionality.
