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.

Claims

1. An apparatus for integrating video and power transmission signals comprising:

a front panel comprising a power indicator;

a back panel comprising an unshielded twisted pair (UTP) I/O terminal, a BNC-coaxial-cable-based video output terminal, and a power input terminal;

a UTP-based video signal converting circuit; and

a power supply circuit;

wherein said UTP I/O terminal receives video signals from said video cameras through UTP-based cables;

said UTP-based video signal converting circuit integrates said video signals received by said UTP I/O terminal, filters noises of said video signals, and then outputs filtered camera video signals to said BNC-coaxial-cable-based video output terminal;

said BNC-coaxial-cable-based video output terminal transmits said filtered camera video signals via a BNC coaxial cable to a digital video server;

said power input terminal, when connected to a power supply, provides power through said power supply circuit to said UTP I/O terminal for supplying power to said video cameras through said UTP-based cables; and

said power indicator is connected to said power supply circuit for indicating whether power is provided to one or more video cameras.

2. The apparatus of claim 1, wherein said front panel comprises a plurality of power indicators.

3. The apparatus of claim 1, wherein said back panel comprises a plurality of said UTP I/O terminals.

4. The apparatus of claim 1, wherein said UTP I/O terminal of said back panel connects to a color camera via said UTP-based cables.

5. The apparatus of claim 1, wherein said UTP I/O terminal of said back panel connects to a black and white camera via said UTP-based cables.

6. The apparatus of claim 1, wherein said back panel comprises a plurality of said BNC-coaxial-cable-based video output terminals.

7. The apparatus of claim 1, wherein said back panel comprises a plurality of said power input terminals.
