1. Field of Invention
The present invention relates to a method and system for monitoring and surveillance. More particularly, the present invention relates to a method and system for remote monitoring and surveillance.
2. Description of Related Art
There is a strong need for both stationary and mobile remote monitoring and surveillance. For example, when an event happens, the commander in the police station has to see remotely through cameras installed on a pre-arrived police car to know what has actually happened at the event scene. In addition, the commander mentioned above also has to see remotely through different cameras installed on a pre-arrived police car to know more about the surroundings of the event scene.
Another example is cash delivery. During the cash delivery, the truck delivering cash is in danger of being robbed. Remotely monitoring the surroundings of the cash delivery truck can reduce the risk of such robberies.
For the foregoing reasons, there is a need for a new method and system for remote monitoring and surveillance.
According to one embodiment of the present invention, a system for remote monitoring and surveillance is provided. The system comprises a plurality of cameras, a router, and a server. The cameras capture scenes, convert the captured scenes into a plurality of image signals, and transmit the image signals by a communication protocol. The router builds a connection with the cameras for receiving the image signals and transmits the image signals by a first wireless communication protocol. The server builds a connection with the router for receiving the image signals by the first wireless communication protocol, processes the image signals to obtain first images, and displays the first images.
According to another embodiment of the present invention, a method for remote monitoring and surveillance is provided. The method comprises the steps of capturing scenes by a plurality of cameras. Then, converting the scenes into a plurality of image signals and using a wireless communication protocol to transmit the image signals to a server. The server processes the image signals to obtain a plurality of images. The images are then displayed on a monitor.
