A multi-location and multi-camera surveillance system includes cameras located at different locations. The cameras are selectively turned on and off by addressable control modules operatively connected to the cameras and a transceiver connected operatively to the modules, which turn off a previously on camera before turning another camera on, thereby to prevent more than one of the cameras from being on at any given time. The on-off actuation of the cameras may be achieved in a sequential fashion.

Multi-camera surveillance and monitoring system

An rf PC interface transmits binary coded radio-frequency (rf) signals which are binary coded in accordance with software resident in a PC. The interface is plugged into a serial port of the PC and includes a pass-through port and an rf modulator. Also disclosed is an rf transceiver which receives and demodulates addressed coded rf signals, which are then combined with the appropriate audiovisual product remote control signals to drive an IR transmitter to produce remote control signals for the addressed audiovisual product.

Rf PC interface

An automated appliance control system includes a unit which transmits binary coded address and function control signals along the a.c. power line to a plurality of appliance control modules connected to the power line at various locations in the home. The binary coded signals transmitted along the a.c. power line are in the form of binary rf bursts which occur before and after the a.c. power line zero crossing points.
