Embodiments of this application provide a fire-fighting switch device and a fire-fighting system, which are applied to the field of fire-fighting. The fire-fighting switch device includes a plurality of fire detection switch units, where the fire detection switch unit includes one or more fire detection switches, the one or more fire detection switches form at least one switch path, the fire detection switch is configured to turn on when a fire is detected, and any one of the switch paths is configured to transmit a voltage signal to a fire-extinguishing device when all of the fire detection switches on the switch path are turned on. In this solution, when a fire is detected by one fire detection switch unit, the fire-extinguishing device can be controlled to extinguish the fire provided that all fire detection switches on one switch path in the fire detection switch unit are turned on.

A short-circuit isolator includes a switch configured to selectively interrupt an electrical circuit connected to the short-circuit isolator. The short-circuit isolator is configured to cause the switch to interrupt the electrical circuit when a current at the short-circuit isolator exceeds a current threshold and at least one of a voltage at the short-circuit isolator is below a voltage threshold or a resistance of the electrical circuit measured at the short-circuit isolator is below a resistance threshold.

Provided is a setting method of a Wi-Fi doorbell (2), in which a Wi-Fi doorbell (2) comprising a camera capable of reading a two-dimensional code and a mobile communication terminal (4) comprising a display unit (6) capable of displaying the two-dimensional code are used. The setting method comprises steps of causing the display unit (6) to display a two-dimensional code in which password information for enabling the Wi-Fi doorbell (2) to connect to a network (5) via a Wi-Fi router (20) is embedded reading the two-dimensional code by the camera (9) of the Wi-Fi doorbell (2); and setting the Wi-Fi doorbell (2) to a state where the Wi-Fi doorbell (2) can perform communication with a remotely disposed server (3) via the Wi-Fi router (20), based on the read two-dimensional code.

A robot control system acquires request information requesting a robot to keep within a prescribed distance from a user and to collect surrounding information, acquires, from the robot, location information indicating a location of the robot and confirmation information indicating that the robot is near the user, and transmits, to the robot, a command for changing a setting of the robot from a first specification to a second specification in response to the request in a case where it is determined, on a basis of the map information, the location information, and the confirmation information, that the user of the robot is accompanying the robot outside a home area of the user, the first specification enabling the robot to collect the surrounding information inside the home area, and the second specification enabling the robot to collect the surrounding information outside the home area.

A fire detector is connected to a loop transmission line connected to a receiver. When the loop transmission line is normal, a transmission unit is connected to the fire detector. When a disconnection failure occurs, a disconnection monitoring unit turns on switching circuits to connect the end of the loop transmission line to the transmission unit, and the receiver connects to the fire detector from both ends of the loop transmission line. An input/output switching booster is inserted and connected in the middle of the loop transmission line, and when the start side transmission line is disconnected and the switching circuits are turned on, the input/output is switched. Accordingly, the input/output switching booster amplifies the down signal input from the terminal side transmission line and outputs it to the start side transmission line and at the same time amplifies the up signal input from the start side transmission line.

A route display apparatus (10) according to the present disclosure includes: an acquisition unit (11) that acquires friend account information of a friend account that is connected online to an account of interest; a specification unit (12) that specifies a traffic site near an activity site of a friend user who uses the friend account based on the acquired friend account information; a calculation unit (13) that calculates an estimated movement route of a user of interest who uses the account of interest, the estimated movement route including the specified traffic site; and a display unit (14) that displays the calculated estimated movement route.

An information processing apparatus (10) includes a time and space information acquisition unit (110) that acquires high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and a corresponding time slot, a possible surveillance target acquisition unit (120) that identifies a video to be analyzed from among a plurality of videos generated by capturing an image of each of a plurality of places, on the basis of the high-risk time and space information, and analyzes the identified video to acquire information of a possible surveillance target, and a target time and space identification unit (130) that identifies at least one of a spatial region where surveillance is to be conducted which is at least a portion of the spatial region or a time slot when surveillance is to be conducted, from among the spatial region and the time slot indicated by the high-risk time and space information, on the basis of the information of the possible surveillance target.

An alarm device for a fire alarm system is described herein. One device includes at least one of an audio notification mechanism and a visual notification mechanism, a supercapacitor, and a controller configured to allow the supercapacitor to power the at least one of the audio notification mechanism and the visual notification mechanism upon a short circuit fault occurring on a loop of the fire alarm system while the alarm device is in an alarm state.

A customer management apparatus (10) includes an acquisition unit (110) and a determination unit (120). The acquisition unit (110) acquires, from a registration terminal (20), first face information and card identification information. When the first face information satisfies a first criterion regarding whether authentication is possible, the determination unit (120) causes a storage unit (130) to store the first face information and the card identification information in association with each other (first registration processing), and performs processing for allowing a customer to enter a store. The processing may be, for example, issuing, to a store entry apparatus (40), a command to open an automatic door, or may be issuing, to the store entry apparatus (40), a command (so-called lock releasing) to cause an automatic door to open when the customer stands in front of the automatic door.
