Abstract: A door-lock control method adopted by a door-lock device and a computer program is present. The method comprises: broadcasting a connecting message in a WPAN at the door-lock device; controlling a mobile device to establish a connection with the door-lock device via the WPAN when receiving the connecting message at the computer program; sending an unlocking command via the connection at the computer; and unlocking a door-lock thereon when receiving the unlocking command at the door-lock device. This application can omit the operations which the householder needs to do manually on the mobile device or the door-lock device, and effectively improves the convenience of use and reduces the waiting time of completing unlocking the door-lock.

Abstract: A release structure of a smart lock includes a circuit unit, a drive unit, and a release element. The circuit unit and the drive unit are placed in a housing, and the drive unit is electrically connected to the circuit unit. The drive unit includes at least one push arm pivotally connected to a rotation pivot and enclosing the same. The release element is placed on the rotation pivot and includes at least one flexible arm placed corresponding to the push arm. The push arm is driven by the drive unit to rotatably contact the at least one flexible arm and cross it, so that the drive unit becomes idle. Accordingly, components in the drive unit are prevented from damages, and a lifespan of the smart lock is prolonged.

Abstract: A remote access control system comprising a remote host connected to a mobile device, a proximity sensor doorbell, a door lock device and a gateway device is provided. The proximity sensor doorbell triggers a doorbell signal when sensing a finger of a visitor approaches. The gateway device sends a first notification message to the mobile device via the remote host when recognizing that a captured monitoring video comprises image of the visitor, sends a second notification message to the mobile device via the remote host when receiving the doorbell signal, and controls the door lock device to unlock when receiving an unlocking message from the mobile device. This system facilitates the householder to control the entry remotely and effectively reduces the probability of doorbell failing.

Abstract: A modularized monitoring apparatus pivotally connected to a supporter includes a photographic module, a lighting module, a communication control module, a power supply module, and a detection module. The photographic module includes a first joint interface. The lighting module includes a second joint interface selectively connected to the first joint interface. The communication control module, the power supply module, and the detection module can be selectively connected to one another, and each includes a third joint interface and a fourth joint interface disposed corresponding thereto. The third joint interface is selectively connected to the first joint interface or the fourth joint interface, and the fourth joint interface is selectively connected to the second joint interface or the third joint interface. The multifunctional modularized monitoring apparatus can rotate and be operated by a smart phone.

Abstract: A doorbell-triggering method first controls the doorbell trigger to switch to a hardware shutdown status when detecting the doorbell trigger is idle; controls the doorbell trigger to switch to an operating booting status to connect to a relay host when receiving a doorbell signal from a button unit of the doorbell trigger under the hardware shutdown status; sends a visiting message to a remote electronic device via the relay host; receives a return image/text message from the relay host and displaying the return image/text message on a display unit of the doorbell trigger. The present disclosed example can substantially reduce the power consumption and the requirement of network bandwidth via automatically switching to the hardware shutdown status when idle and using the image/text message having smaller data size to respond the visitor.

Abstract: A remote communication method of a network includes a main controller and a plurality of control units, wherein each control unit is serially connected to the main controller and the control unit at next stage through a transmission terminal and a transmitter. Each control unit receives the data sent from the main controller and identifies the received data as one of a first, a second and a third packet. If it is the first packet and the main controller attempts to read data from each control unit, a switch in the control unit is turned on and a response data is transmitted to the main controller. If it is the second packet and a connection index is equal to a target unit address, then data is written to a corresponding single control unit. If it is the third packet and a target unit address is zero, data is written to all control units.
