A matrix switch is a hardware device that routes video signals from multiple input sources to multiple output displays. Users can control which camera feed appears on which monitor in real time.
In surveillance systems, matrix switches help manage large numbers of cameras and monitors. For example, security staff can instantly switch views between different zones without disrupting the entire display setup.
Modern systems often combine matrix switching with digital video recorders (DVRs) or video management software (VMS). This setup provides greater flexibility and improves operational efficiency.
As a result, matrix switches remain valuable in control rooms, especially in environments that require centralized monitoring and fast switching.
