Systems and methods to provide a portable alarm, are disclosed herein. The system may include a top component that includes a connector, a first securing protrusion, and a second securing protrusion that extend out a bottom side of the top component; and a base component that includes a narrow cavity, a first notch, a second notch, and a battery-powered circuit board, the first securing protrusion, the second securing protrusion, and the connector engaging with or otherwise connecting with the first notch, the second notch, and the narrow cavity, respectively, to provide secure contact between the top component and the base component, the narrow cavity is linked to the battery-powered circuit board so that responsive to the connector being disengaged from the narrow cavity, an alarm is activated and responsive to the connector being engaged with the narrow cavity, the alarm is deactivated.

An analytical recognition system includes a video camera, an antenna, and a data analytics module. The video camera is configured to capture video data. In some embodiments, the video camera is at least one of a traffic camera or an aerial drone camera. The antenna is configured to capture mobile communication device data. The data analytics module is configured to correlate the video data and the mobile communication device data to generate a profile of a person associated with the video data and the mobile communication device data. The profile has profile data including any one or a combination of the captured video data and the captured mobile communication device data.

When Law Enforcement and Military teams are entering a premises or hostile environment, they often use a distraction device to create temporary confusion and disorientation of target individuals. Conventional flash-bangs carry significant risk of collateral damage through fire, smoke inhalation, high temperature burns and fragmentation. The invention proposes a modular, reloadable, non-lethal solution offering various form factors. They significantly reduce/eliminate collateral damage. The devices utilise the same principle—single or multiple machined port(s), plus pyrotechnic ignitor. Gas pressure expanding inside each port ruptures a membrane. The release of this pressure creates a sound impulse. For GMOE (Glass method of Entry) Hand-held, Wired & RF initiated devices, gas pressure created by the ignitor functioning drives a captive hardened steel punch forward. The punch ruptures a membrane on the front face of the device breaking any glass it is in contact with.

A wireless door lock system with an emergency reporting function includes a user device, a door lock device, a network server and at least one recipient device. When the user device transmits a request signal for reporting an emergency condition to the door lock device, the door lock device determines if the user device is a paired device of the door lock device according to the request signal and further sends an emergency condition confirmation signal to the user device by way of wireless communication. The user device is then connected to the network server through the Internet and transmits an emergency condition signal to activate the network server to perform a push notification service and send an emergency condition message to the at least one recipient device. Given the push notification, the emergency condition message can be instantly provided to right recipients for emergency condition notification.

A personal alert device for sending a panic signal and location coordinates includes a housing that defines an internal space. An inlet is positioned in a first end of the housing. The first end is configured to position between lips of a user. An outlet is positioned in the housing such that air passing from the inlet through the internal space and exiting through the outlet generates a whistling sound. A wall, coupled to the housing and positioned in the internal space, defines a compartment. An electronics module positioned in the compartment is configured to wirelessly communicate, to receive location coordinates, and to be activated by a user blowing air through the inlet. The housing emits the whistling sound and the electronics module is compelled to wirelessly communicate the panic signal and the location coordinates to at least one cellular phone and to emergency response personnel.

A personal protection device, including a central casing including a battery, a toggle button connected to the battery, and a sealed housing including a coil switchably connected to the battery and a liquid, such that pressing the toggle button connects the battery to the coil to heat the liquid to convert the liquid to a gas until an audible shock wave is generated.

The disclosed embodiments provide an improved monitoring and security system to identify the presence of persons within a premises, to track the relative location of the person as he or she traverse the premises, and to generate an alert and optionally enter a lockdown mode if the person does not possess a pre-registered computing device or wireless transceiver. In the lockdown mode, doors optionally can be shut and locked through remote or local control or automatically if the distance between the person and the particular door falls below a predetermined threshold.

Provided is a device and method for controlling the activation of crime prevention equipment, which are capable of fundamentally blocking the accidental use of the crime prevention equipment and varying operation modes of the crime prevention equipment in response to dangerous situations. The provided device may include: an image analysis unit extracting an image of another person from an image from a user terminal and analyzing a motion of the other person based on the extracted image of the other person; a voice analysis unit analyzing a frequency of voice from the user terminal and extracting a preset search word from the voice; a danger identification unit identifying a level of danger of a user based on results of the image analysis unit and the voice analysis; and an operation mode determination unit determining an operation mode in which crime prevention equipment possessed by the user is activated according to the level of danger identified by the danger identification unit, and transmitting a signal corresponding to the operation mode to the user terminal.

Systems and methods for communicating in a network using share signals in accordance with various embodiments of the present disclosure are provided. In one embodiment, a method for communicating in a network may include receiving, from a first client device, a share signal including first image data captured by a camera of a first audio/video (A/V) recording and communication device and a command to share the first image data with a network of users; processing the share signal by comparing the first image data to second image data captured by a camera of a second A/V recording and communication device; and generating and transmitting an alert to a second client device associated with the second A/V recording and communication device when comparison of the first image data with the second image data indicates a person of interest is depicted in both the first image data and the second image data.
