A security alarm system includes a camera, an alarm control panel, a mixer at the camera, a signal processor at or associated with the alarm control panel, and a single cable comprising only two operative conductors extending between the mixer and the signal processor. The cable provides current to the camera via the mixer and provides a tamper circuit as well as conveying video signals to the signal processor.
