APPARATUS FOR INTEGRATING VIDEO AND POWER TRANSMISSION SIGNALS

Abstract

An apparatus for integrating video and power transmission signals that comprises a front pane, a back panel, a power indicator, an unshielded twisted pair (UTP)-based video signal converting circuit, a power supply circuit, a UTP I/O terminal, a BNC coaxial cable-based video output terminal, and a power input terminal, said apparatus connecting to a plurality of video cameras, each having an independent UTP I/O terminal. Such cameras can transmit video and receive power signals through individual UTP cables, said apparatus receiving a first signal and filtering noises of said first signal to output a second signal via a BNC-coaxial-cable-based video output terminal to a digital video server, thereby integrating all monitoring and power transmission signals in said apparatus to effectively lower procurement costs and reduce the amount of space required for installation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIG. 1˜3. The apparatus for integrating video and power transmission signals comprises a front panel (3a), a back panel (3b), a plurality of power indicators (30), a UTP-based video signal converting circuit (21), a power supply circuit (22), a plurality of UTP I/O terminals (31), a plurality of BNC-coaxial-cable-based video output terminals (32), and a plurality of power input terminals (34). In this embodiment, said apparatus (3) connects to one or more cameras (1) and UTP converters (11) via UTP-based cables (2) attached to UTP I/O terminals (31), and also connects to a power supply (4) via a plurality of power cords (35) which couple to said power input terminals (34). This arrangement allows said apparatus (3) to provide power to said cameras (1) through said built-in power supply circuit (22) coupled to said UTP I/O terminals (31) and said UTP-based cables (2).

On the other hand, camera video signals received by said apparatus (3) are filtered by said UTP-based video signal converting circuit (21) and then sent through said BNC-coaxial-cable-based video output terminals (32) and BNC coaxial cables (33) to a digital video server (5), thereby integrating all monitoring capabilities in one apparatus to effectively lower procurement cost and reduce the space required for installation. Furthermore, all the cables are connected through said back panel (3b) for the user's and installer's convenience, while only the power indicators are implemented on said front panel (3a) for easy operation and maintenance.

Many changes and modifications in the above described embodiment of this invention can, of course, be carried out without departing from the scope of the present invention. Accordingly, to promote progress in science and the useful arts, this invention is disclosed and is intended to be limited only by the scope of the appended claims.
