Abstract

A multi-point security system employing network communication is provided. The system includes a main unit (10) being connected to a digital server (50), a video and audio recording unit (20) and a sensor and alarm unit (30), wherein the video and audio recording unit (20) and the sensor and alarm unit (30) are formed by a plurality of monitoring devices (21) and sensors (31), which simultaneously collect scanning data and feed the data back to the main unit (10) by wireless means. Multiple monitoring points can be set up in strategic locations for close surveillance of the site situation around-the-clock, and the scanning data can be accessed through a personal computer (60) or cellular phone (61) with a predetermined network or email address.

Claims

1. A multi-point security system employing network communication comprising:

a main unit (10) formed by a signal conversion circuit (11) and a receiver circuit (12), wherein the signal conversion circuit (11) is connected to the input of the receiver circuit (12), whilst the output of the signal conversion circuit (12) is linked to a digital server (50);

a video and audio recording unit (20), formed by a plurality of monitoring devices (21) having video and audio recording capability and corresponding transmitter circuits (22), for converting the video and audio signals to RF signals before sending them to the main unit (10); and

a sensor and alarm unit (30), formed by a plurality of sensors (31) possessing a specific sensing function, corresponding buzzer alarms (32) and transmitter circuits (33), where each sensor (31) and alarm (32) can be installed at any location within the signal reception range of the main unit (10), such that video and audio signals can be transferred back to the main unit (10) for signal processing;

wherein the main unit (10) connected to a digital server (50) is able to process video and audio signals from the video and audio recording unit (20) and the sensor and alarm unit (30) to pick out any irregularity on the scan site, and then to transmit the scanning data to a remote personal computer or cellular phone controlled by an owner user through an Internet connection.

2. The multi-point security system employing network communication as claimed in claim 1, wherein the main unit (10) comprises:

a receiver circuit (12) for receiving RF signals carrying scan data;

a decoder (14) being connected to the output of the receiver circuit (12) for decoding the received video and audio signals from the receiver circuit (12); and

a converter (15) being connected to the output of the decoder (14) for converting the decoded signal to a standard format readable by the digital server (50).

3. The multi-point security system employing network communication as claimed in claim 2, wherein the converter (15) can be built with an IC supporting USB specifications.

4. The multi-point security system employing network communication as claimed in claim 2, wherein the security system further includes an AC/DC power circuit.

5. The multi-point security system employing network communication as claimed in claim 3, wherein security system further includes an AC/DC power circuit (40).

6. The multi-point security system employing network communication as claimed in claim 4, wherein the AC/DC power circuit (40) includes:

a filtering circuit (41) having a low voltage output; and

a switching circuit (42) being installed in between the output of filtering circuit (41) and the battery (44), such that when AC input is terminated, the DC circuit is ready to provide DC power.

7. The multi-point security system employing network communication as claimed in claim 5, wherein the AC/DC power circuit (40) includes:

a filtering circuit (41) having a low voltage output; and

a switching circuit (42) being installed in between the output of filtering circuit (41) and a battery (44), such that when AC input is terminated, the DC circuit is ready to provide DC power.

8. The multi-point security system employing network communication as claimed in claim 1, wherein the transmitter circuit (32) is formed by an encoder (331) and an RF transmitter (332).
