1.Basic Concept of “Single-Point Grounding”Single-point grounding refers to a configuration in which the main system host is connected to earth at one single point, while all remote devices—including cameras and other equipment—must remain electrically insulated from earth. Specifically, “single-point grounding” means that for any “system” where components are directly electrically connected, the central aggregation point (i.e., the main system host or subsystem host) must be grounded at one poi
