The first camera unit includes a first camera lens and a first image sensor, generating a first video. The second camera unit includes a second camera lens and a second image sensor, generating a second video. The processing unit selectively activates one of the first camera unit and the second camera unit according to at least one of the first video, the second video, and a state of the doorbell button.

Doorbell device and method thereof

The access method includes the following steps. Firstly, multimedia data is accessed with a multimedia access device located on a local network, which connected to a public network via a network address translation (NAT) or firewall device. Next, first communication link between a portal server and the multimedia access device is established. Then a piece of punch-through information indicating whether the multimedia access device can punch through the NAT/firewall device is obtained in response to an inquiry command provided by a client device. Next, when the multimedia access device cannot punch through the NAT/firewall device, the multimedia data is pushed from the multimedia access device to the portal server and the multimedia data pushed to the portal server is further pulled from the portal server to the client device, so that multimedia data transmission between the client device and the multimedia access device can be obtained.

Accessing method and multimedia system using thereof

A bridge system for installing electronic appliance to light source socket and a bridge method are disclosed. The system includes a light source plug, a power line communication module and a connection unit. The light source plug is electrically connected to the light source socket to perform data communication through the power lines. The power line communication module is electrically connected to the light source plug to convert AC power into DC power and perform analog-to-digital data conversion simultaneously through the power lines. The connection unit is electrically connected to the electronic appliance to provide AC or DC power and transmit converted digital data to the electronic appliance. Accordingly, there is no need to add power cables or power adapters.
