FIG. 2 illustrates a security system according to an embodiment of the invention. The security system 200 of the present invention comprises monitoring sensors 210 and a video camera 220. The monitoring sensors 210 act as the environment watchdogs for monitoring the changes of the environment to generate status signal when a triggering event happened. In an embodiment, the type of monitoring sensors 210 will be battery-powered and communicate with the video camera 220 through wireless signals. In other words, the monitoring sensor 210 is a wireless sensor. The type of the monitoring sensors 210 is contact sensor, motion sensor, or vibration sensor. However, in other embodiment, other type of monitoring sensor may be also used in the present invention, and the present invention is not limited to the type of monitoring sensor. The status signal generated by the monitoring sensors 210 is transferred to the video camera 220 to notify the video camera 220 a triggering event happening. Then, the video camera 220 performs a security process in response to the triggering event. Moreover, the security system further comprises a cloud server 230 to directly communicate with the video camera 220 through an Internet link. The cloud server 230 is a network server that is built, operated and accessed remotely through internet. The present invention is not limited to the type of the cloud server. Therefore, the notification from the video camera 220 can be transferred to a remote portable device 240 from the cloud server 230. In an embodiment, the security process either sends a notification message to the cloud server 230, or the video camera 220 starts to capture video, or both. The cloud server 230 receives the notification message or the captured video file from the video camera 220 through Internet. Then, the cloud server 230 may notify the end user about the triggering events through the portable device 240 or other devices. The cloud server 230 also stores the captured video files which are uploaded from the video camera 220. In an embodiment, a cloud-based application software installing and operating in the cloud server 230 performs the above function. The cloud-based application software provides UI/UX front-end applications to the end users. The application can be mobile applications, web applications, or PC applications which the end users can use the portable device 240 to receive and retrieve the status about their home form the cloud server 230. In an embodiment, the video camera 220 is an IP-based camera. Through a standard IP network configuration, the video camera 220 can communicate with the cloud server 230. By using the standard IP network configuration as the link connectivity, a portable device 240 can utilize the existing broadband internet services to communicate with the security system 100 without any additional or proprietary network configuration. In an embodiment, the portable device 240 is a mobile phone, a laptop computer or a tablet computer. In another embodiment, when the user is in a location near the video camera 220 and a portable device of the user can directly receive notification from the video camera 220, it is not necessary for the security system 200 to use a cloud server 230 to transfer notification to the user. The user can directly communicate with the video camera 220 to receive the notification. Therefore, in this embodiment, the cloud server 230 is an optional apparatus for the security system 200. FIG. 3 is a schematic diagram of the video camera according to an embodiment of the invention. The video camera 220 has an interface 221 and a DIDO terminal port 223. The video camera 220 uses the interface 221 for connection with other devices, data link to the cloud server 230 to upload the captured video files, and update the received status signal from the monitoring sensors 210. Also, the video camera 220 utilizes the interface 221 to receive the commands from the cloud server 230. The interface 221 is a WIFI or an Ethernet interface, but the present invention is not limited to the aforesaid. On the other hand, the video camera 220 uses the DIDO terminal port 223 to connect with a wireless transceiver module 222. Then, the monitoring sensors 210 may wireless communicate with the video camera 220 through the wireless transceiver module 222. The status signal generated by the monitoring sensors 210 is transferred to the wireless transceiver module 222. Then, the status signal changes the logic state of pin in the DIDO terminal port 223 to trigger the video camera 220 for capturing video.
FIG. 4 illustrates the connection between the video camera 220 and the wireless transceiver module 222 according to an embodiment of the invention. The wireless transceiver module 222 has a DIDO terminal port 224 to connect with the DIDO terminal port 223 of the video camera 220. By the connection of the DIDO terminal port 224 and 223, the video camera 220 and the wireless transceiver module 222 are connected together. In general, a DIDO terminal port 224 or 223 has four pins, a power pin, a ground pin, a DI pin for digital input and a DO pin for digital output. Consequently, the DIDO terminal port 224 could be implemented by two IO pins or GPIO (General Purpose Input Output) pins easily. The status signal received by the wireless transceiver module 222 is outputted from the DO pin of the DIDO terminal port 224 to the DI pin of the DIDO terminal port 223 in the video camera 220. Then, the video camera 220 detects a change in the logic state of the DI pin. In an embodiment, the change logic state of the DI pin can trigger the video camera 220 to perform security process, such as to record a video or to send a notification message to the cloud server 230. Accordingly, when the wireless transceiver module 222 receives the status signal from the monitoring sensors 210, the wireless transceiver module 222 will change the DO pin logic state of the DIDO terminal port 224 so as to change the DI pin logic state of the DIDO terminal port 223, for example, pull high the voltage level on the pin. Then, the video camera 220 detects a change in the logic state of the DI pin of the DIDO terminal port 223, which will trigger the video camera 220 to perform security process. In other words, the change in the logic state of the DI pin of the DIDO terminal port 223 will notify the video camera 220 that there is a sensor trigger event happening. Then, the video camera 220 will perform following security process, either sending a notification message to the cloud server 230, or start a video capturing, or both.
In an embodiment, when the cloud server 230 receives the notification message, the cloud server 230 may notify the end user through the portable device 240. The notification message is a real-time notification. Therefore, the end user may immediately know, such as, there is an intrusion event happening. In an embodiment, the notification message is sent to the end user through an APP, an Email, a Short Message Service (SMS) or a Multimedia Messaging Service (MMS). However, other notifying methods also can be used in the present invention. On the other hand, in another embodiment, when the video camera 220 is enabled with the video capturing function, during a triggering event, the video camera 220 will start a real-time video recording to capture the activities. In an embodiment, the video file captured by the video camera 220 may be sent to the cloud server 230 for storing through a standard FTP protocol or other data transferring protocol. Therefore, the end user can sends a request through the portable device 240 to the cloud server 230 to access the video file after the triggering event. Moreover, the end user also can send a request through the portable device 240 to the cloud server 230 to access the video camera 220 for live viewing. In this embodiment, the cloud server 220 passes the live viewing request from the portable device 240 to the video camera 220. Moreover, aforementioned cloud-based application software are also executed and controlled by the end user through the portable device 240. When the video camera 220 receives the live viewing request, the video camera 220 passes the live viewing stream to the portable device 240 through the cloud server 230. Therefore, the end user can view the live viewing through the portable device 240.
FIG. 5 illustrates a security method according to an embodiment of the invention. Please refer to FIG. 2 and FIG. 5. According to the security method 500, especially applied without gateway, in step 501, a status signal is generated when a triggering event happening. In an embodiment, when a triggering event happening, the event triggers the monitoring sensors 210 to generate the environment status signal. Next, in step 502, the status signal is transferred to a video camera to notify the video camera that triggering event occurs. In an embodiment, the status signal is transferred to the wireless transceiver module 222 that is connected to the video camera 220 through a DIDO terminal port 223. Then, in step 503, the status signal triggers the video camera to perform a security process to generate a notification in response the triggering event. In an embodiment, the status signal changes the logic state of the DI pin of the DIDO terminal port 223 to trigger the video camera 220 in response to the triggering event. Moreover, the security method further comprises the following steps: directly communicating with the video camera 220 through an Internet by a cloud server 230, transferring the notification from the video camera 220, and transferring the notification to a remote portable device 240 via the cloud server. Therefore, the video camera 220 performs a security process, including generating a notification message, transferring the notification message to a cloud server 230, or/and starting to capture a video. Accordingly, in step 504, the cloud server 230 may notify the end user according to the received notification message. However, in another embodiment, when the user is in a location near the video camera 220 and a portable device of the user can directly receive notification from the video camera 220, it is not necessary for the security system 200 to transfer notification to the user through a cloud server 230. The user can directly communicate with the video camera 220 to receive the notification.
Accordingly, according to the present invention, the security system and method thereof eliminate the traditional gateway device. Therefore, not only the cost of the security system is reduced, but also the installation process of the security system is simplified. Moreover, the security system of the present invention leverages the data processing capabilities from the video camera to offer the same functionalities. Therefore, no additional changes or modifications are required to the monitoring sensors and video camera.
