## Abstract

A method and an apparatus for remote monitoring. A signal capturing device running a Web operating system captures an audio signal and/or a video signal, and transmits the captured signal to a remote monitoring device via a communication link between the signal capturing device and the remote monitoring device. The remote monitoring device also supports the Web operating system to allow the communication link to be established using WebRTC technology. The audio and/or video unit of the signal capturing device is accessed through a MediaStream port.

## Claims

### Claim 1

A method implemented by a remote monitoring device, the method comprising:
receiving video signals of different times captured by a video camera from a signal capturing device through a communication link established between the signal capturing device and the remote monitoring device using WebRTC technology, wherein the signal capturing device and the remote monitoring device both run a Web operating system;
processing the video signals of the different times at the remote monitoring device for remote monitoring;
loading web codes of video data;
defining a specific real-time comparison of different moments in the loaded web codes of video data; and
using a specific difference in a result of the specific real-time comparison as a condition to set off a particular device.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising sending to a user a feedback of a remote monitoring result obtained after processing the video signals.

### Claim 3 (depends on 2)

The method according to claim 2, wherein sending to the user the feedback of the remote monitoring result comprises sending a text message or an email to the user.

### Claim 4 (depends on 2)

The method according to claim 2, wherein the feedback of the remote monitoring result is displayed in a web browser.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising: sending from the remote monitoring device an operation command to the signal capturing device.

### Claim 6

A remote monitoring system, the system comprising a computing device having one or more processors and memory, wherein the computing device runs a Web operating system and is programmed to have functional modules including:
a signal receiving module for receiving video signals of different times captured by a video camera of a signal capturing device through a WebRTC communication link between the signal capturing device and the signal receiving module; and
a signal processing module for:
processing the video signals of the different times for remote monitoring,
loading web codes of video data,
defining a specific real-time comparison of different moments in the loaded web codes of video data, and
using a specific difference in a comparison result as a condition to set off a particular device.

### Claim 7 (depends on 6)

The system according to claim 6, wherein the computing device is programmed to send to a user a feedback of a remote monitoring result obtained after processing the video signals.

### Claim 8 (depends on 7)

The system according to claim 7, wherein the feedback of the remote monitoring result is displayed in a web browser.

### Claim 9 (depends on 6)

The system according to claim 6, wherein the computing device is programmed to send an operation command to the signal capturing device.
