Abstract: A gateway using a single database at least has a microprocessor unit and a Radio Frequency (RF) module. The RF module is used to be paired with an external sensor for connection. There is a main operating system operating in the microprocessor unit. In the main operating system, there is a integrated control system. The integrated control system integrates and records point-to-point (P2P) connection function, web page connection function and definition of operating data and instructions to the sensor for the gateway. With the integration of the integrated control system, a sensor operating system, a P2P control module and a web page connecting module in the main operating system share one main database to retrieve definition of the same data and instructions. With such, communication protocol problems among systems and modules in the main operating system are reduced and such design is helpful for developing and porting of firmware.

Abstract: A peer-to-peer connection system for peer-to-peer connection path routing provides an optimal connection path between a client electronic device and a target subsystem. The peer-to-peer connection system comprises a target subsystem, at least one relay subsystem and the client electronic device. The target subsystem and the relay subsystem connect to internet via different routers respectively. The target subsystem comprises a target device; the relay subsystem comprises a relay device. The target device and the relay device transmit a connection quality table to the client electronic device respectively. The client electronic device determines the optimal connection path according to the connection quality tables. This application program can provide the optimal peer-to-peer connection path via making the relay device be a relay node of peer-to-peer connection according to the connection quality tables.

Abstract: A dual peer-to-peer connection system for obtaining a registration information of a remote network device from internet. The dual peer-to-peer connection system of this application comprises a subsystem and a user electronic device. The subsystem operatively connected to a router comprises a remote network device and a subsystem server. The user electronic device establishes a connection with the subsystem server according to a registration information of the subsystem server. The user electronic device obtains the registration information of the remote network device. The user electronic device establishes a connection with the remote network device according to the register information of the remote network device. This application can prevent from failing to obtain the registration information of the remote network device because of a peer-to-peer server being not connectible via configuring the subsystem server and the remote network device to the same router.

Abstract: A video storage system includes a security mechanism between a CVR unit and a CVR manager. The security mechanism provides public and private keys according to asymmetric cryptography. The public key is sent to the CVR manager. The CVR manager produces a plaintext of a video footage from an IP camera. The CVR manager produces and uses a random key according to symmetric cryptography to turn the plaintext of the video footage into an encrypted text, uses the public key to turn the random key into an encrypted text, and respectively sends the encrypted texts into video and key databases in the CVR unit. The encrypted texts can be received from the databases. The private key turns the encrypted text of the random key into the random key. The random key turns the encrypted text of the video footage into the plaintext.

Abstract: A video storage system includes a CVR manager including a software program of management run therein, at least two IP cameras connected to the CVR manager via the Internet; and at least two CVR units connected to the CVR manager via the Internet. The CVR manager assigns each of the CVR units to store a file of video data produced by a corresponding one of the IP cameras. Thus, the CVR manager distributes the video data produced by the cameras to the CVR units. Hence, the video storage system is inexpensive and highly expansible.
