Hazardous or dangerous conditions may be monitored. A mode may be set to a state indicative of the condition being present. It may then be determined that the hazardous or dangerous condition has eased. An indication of the hazardous or dangerous condition easing may be output in response to the determination. Such an indication may be output as synthesized speech.

Various arrangements are presented for controlling a night light feature of a hazard detector. A user interface application executed on a mobile device may output, a graphical interface that provides an option to enable a night light feature of the hazard detector. The application may transmit data indicative of the night light feature being enabled and of an associated user account to a computer server system. The computer server system may receive and store data indicative of the night light feature being enabled and of the user account. The hazard detector may receive from the computer server system data indicative of the night light feature of the hazard detector being enabled by the application. The hazard detector may enable the plurality of LEDs to provide illumination in response to the received data indicative of the night light feature of the hazard detector being enabled by the application.

Communicating with law enforcement agencies using client devices that are associated with audio/video (A/V) recording and communication devices are provided. In one embodiments, a method for a client device for preventing redundant calls to an emergency call center is provided, the method comprising: receiving, at the client device, a notification, along with video footage associated with the notification, about an event generated by an A/V recording and communication device, the video footage captured by a camera of the A/V recording and communication device; receiving a request for contacting the emergency call center; informing one or more backend devices, in communication with the client device and a home security monitoring center that monitors a security system, of the received request to suppress a potential redundant call to the emergency call center from the home security monitoring center; and contacting the emergency call center.

Embodiments of the present disclosure provide a method of on-site speech broadcasting. The method includes receiving text signal, wherein the text signal is generated in response to a parameter reaching a predetermined value sensed by an on-site sensor (110) arranged in the field; converting the text signal to a speech signal by a speech converting module (210) disposed within an on-site speaker device (200); playing the converted speech signal by using a speaker (220) of the on-site speaker device (200). Embodiments of the present disclosure also provide an on-site speaker device and an on-site speech broadcasting system. With the embodiments of the present disclosure, an effective text-to-speech conversion is achieved, pre-created speech data is not necessary and the workload of design is reduced, making it more cost effective. Meanwhile, speech messages being broadcasted allow operators instantaneously knowing the content of the alarm. Therefore, the operators are able to position and tackle the problem right away, improving efficiency and safety.

In various embodiments, a hazard detector may be presented. The hazard detector may include at least one hazard detection sensor that detects a presence of at least one type of hazard. The hazard detector may include a speaker, a light, and a motion detection sensor that detects motion in an ambient environment of the hazard detector. A processing system of the hazard detector may be configured to select an illumination state based on a determined status. The processing system may cause the light to illuminate based on the selected illumination state. The processing system may determine a gesture has been performed in the ambient environment of the hazard detector following the light being illuminated based on the selected illumination state. The processing system may output a detail of the status via the speaker corresponding to the illumination state in response to determining the gesture has been performed.

The present disclosure relates to a personal security platform. In particular, the present disclosure relates to such systems designed to be worn or attached to one's garment during use to provide safety and security measures and help if facing hostility, aggression, harassment, or any other emergency situation mostly while in an outdoor activity such as biking, jogging, walking, usage of any open vehicle and the like. Additionally, another aspect of the security platform is protecting users of open vehicles, where a signaling system is provided, comprising a vest or a wearable item having a rear-facing display, a controller and optionally, a front-facing display. The vest is configured to communicate with the controller for operating the display. The controller is configured to operate the display based at least on data from a GPS module and one or more motion sensors.

Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.

Hazardous or dangerous conditions may be monitored. A mode may be set to a state indicative of the condition being present. It may then be determined that the hazardous or dangerous condition has eased. An indication of the hazardous or dangerous condition easing may be output in response to the determination. Such an indication may be output as synthesized speech.

Provided are a portable security device having a rescue request function based on IoT which sprays tear gas to perform self-protection, automatically transmits a rescue request message and notifies a rescue requester of a response of a rescuer to the rescue request message to relieve the rescue requester, and a security system using the same.

Various arrangements are presented for controlling a night light feature of a hazard detector. A user interface application executed on a mobile device may output, a graphical interface that provides an option to enable a night light feature of the hazard detector. The application may transmit data indicative of the night light feature being enabled and of an associated user account to a computer server system. The computer server system may receive and store data indicative of the night light feature being enabled and of the user account. The hazard detector may receive from the computer server system data indicative of the night light feature of the hazard detector being enabled by the application. The hazard detector may enable the plurality of LEDs to provide illumination in response to the received data indicative of the night light feature of the hazard detector being enabled by the application.
