A surveillance apparatus (100) includes a feature value storage apparatus (200) that associates and stores a feature value of a person belonging to the same group, a detection unit (102) that detects an approach of a person not belonging to the same group to the person belonging to the same group within a reference distance by processing a captured image by using the feature value, and an output unit (104) that performs a predetermined output by using a detection result of the detection unit (102).

A gunshot detection system includes gunshot sensor units with microphones for detecting gunshots and capturing audio data depicting the detected gunshots and other ambient sounds, an environmental board with various environmental sensors for generating environmental data indicating environmental conditions. The audio data, environmental data, and position information can be stored locally on local nonvolatile storage of the gunshot sensor unit for later retrieval by law enforcement entities. In one embodiment, the gunshot sensor units include a wired and/or wireless data transfer interface for transferring the audio data, environmental data and/or position information to handheld units of law enforcement entities. The gunshot sensor unit can also stream live captured audio data for live monitoring by a control panel, and might also include speakers for providing audio playback of audio data from the control panel.

The present invention provides an image processing apparatus (10) including: a companion determination unit (12) that determines a companion of each of a plurality of persons detected from an image, based on the image; a distance computation unit (13) that computes a first distance being a distance to the nearest person among the persons other than a companion, for the each person; and a risk information generation unit (14) that generates, with use of the first distance, infection risk information being information related to a risk of getting an infectious disease or a safety rate of not getting an infectious disease within a target region being a region included in the image.

A bed-leaving prediction device (server device) (10) is connected through a digital communication network (60) to: a portable information processing terminal (40) of care staff; environmental sensors (32 to 34) for detecting environment values such as temperature in a room; a human sensor (31); and a bed sensor (35). A bed-leaving prediction processing section (115) calculates a bed-leaving prediction value indicative of a degree of possibility that a care recipient leaves a sleeping furniture after a second time interval has expired since a current time point based on a plurality of environment values detected in a time period between the current time point and a time point before expiration of a first time interval, outputs of the human sensor, and outputs of the bed sensor. A bed-leaving notification processing section (117) compares the bed-leaving prediction value with a threshold value, and transmits, to the portable information processing terminal, a bed-leaving notification indicating that the care recipient leaves the sleeping furniture after the second time interval expires when the bed-leaving prediction value exceeds the threshold value.

An image processing apparatus includes an image processing unit and a risk information generation unit. By processing at least one image, the image processing unit identifies a caution-requiring location being a location where a proximity indicator being an indicator related to a proximity state between a plurality of persons satisfies a criterion. The risk information generation unit outputs information indicating the caution-requiring location. For example, the information is displayed on a display unit through a display control unit. For each person, the image processing unit computes a first distance being the distance to the closest person to the person. Then, for each of a plurality of locations, the image processing unit counts the number of times the first distance has a reference value or less. Then, the proximity indicator is set by using the number of times the first distance has the reference value or less.

An address system for at least one fire loop 20 includes at least one remote unit 14, 16, 18 and an address card 102. The remote unit 14, 16, 18 is for installation on the fire loop 20 and for addressable communication via the fire loop 20. The address card 102 is for use with the remote unit 14, 16, 18 in order to provide an address for the remote unit 14, 16, 18. The address card 102 includes one or more of a plurality of optically recognisable colour elements 201-210 for encoding an address. The remote unit 14, 16, 18 includes an optical sensor 116 for identifying colour characteristics of the optically recognisable colour elements 201-210, and a control system 118 for determining the address from the colour characteristics.

A detection system (10) for hazard detection is provided. The detection system (10) includes a control loop (16); an addressable base unit (18) connected to the control loop (16), the base unit (18) including a first near-field communication module (22) storing a unit address; and a mounting unit (20) removably coupled to the base unit (18), the mounting unit (20) including a second near-field communication module (24) operable to read the unit address from the first near-field communication module (22) and store the unit address so that the mounting unit (20) is thereby addressable via the control loop (16).

According to one embodiment, an information processing device includes: a first memory; a first receiver; a first determination section; and a first transmitter. The first memory is configured to store first image data of interior of a vehicle at a first point in time. The first receiver is configured to receive second image data of the interior of the vehicle at a second point of time from the vehicle. The first determination section is configured to determine whether a change has been caused in the interior of the vehicle between the first point in time and the second point in time. The first transmitter is configured to transmit first data based on the determination result.

A space monitoring system includes environment measuring means for measuring an atmospheric environment of a monitored space (S), person sensing means for sensing the existence of a person in the monitored space (S), space condition calculating means for calculating whether the monitored space is an indoor environment likely to cause droplet infection or whether the monitored space is expected to become an indoor environment likely to cause droplet infection, based on atmospheric environment data measured by the environment measuring means and person data sensed by the person sensing means, and display means for displaying an indication for facilitating a user to improve an existing indoor environment likely to cause droplet infection or prevent the monitored space from becoming an indoor environment likely to cause droplet infection, based on a result of calculation by the space condition calculating means.
