Abstract:
An analog video network system for producing a recorded output of a video image, said analog video network system comprising:a video camera for producing an analog video signal corresponding to a video image; a video monitor for receiving said analog video signal and displaying a video image according to said analog video signal; an analog video output device for receiving said analog video signal and producing a recorded output according to said analog video signal, which output is a functional replica of said video image; a relay which, in an inactive state, connects said video camera to said video monitor so as to cause said video monitor to display said video image; and, in an active state, said relay connects said video camera to said video monitor through said analog video output device so as to cause said analog video output device to produce said recorded output and said video monitor to display said video image; and, a controller for activating and deactivating said relay. wherein said relay comprises a six terminal double-pole double-throw relay having first, second, third, wherein said first terminal is electrically connected to an input of said analog video output device, said second and fourth terminals are electrically connected one to the other by means of a jumper, said third terminal is electrically connected to an output of said video camera said fourth terminal is electrically connected to an input of said video monitor, and said sixth terminal is electrically connected to an output of said analog video output device; whereby, when said relay is in said inactive state, said second and third terminals are electrically connected one to the other, and said fifth and sixth terminals are electrically connected one to the other, thus connecting said video camera to said video monitor; and whereby, when said relay is in said active state, said first and third terminals are electrically connected one to the other, and said fourth and sixth terminals are electrically connected one to the other, thus connecting said video camera to said video monitor through said analog video output device.
