A personal safety device is a device designed to protect a person against a potentially dangerous situation. Personal alarms are simple devices used to inform or alarm people about potential danger. They are frequently used in combination with other personal security devices, like pepper spray or stun guns, to notify others about potential danger. A personal safety device has several key components, including an audible device or siren, emergency contact information, and mechanisms that will release a counter-charge of electricity when the contact information is triggered, o get more enlightnened see more here.
When used in combination with other personal security devices, personal alarms can be very effective. Some devices are triggered by doors or windows, giving the wearer or others around them time to escape. Others are triggered by movement, giving the wearer or others a series of shocks to the body when the contact information is entered into the device. Still others are set off by changing magnetic fields, allowing the device to identify itself after being removed from a pocket, bag, or wallet. These devices can also be set off by barking dogs, car engines, or microwave ovens.
The first component of a personal safety device is an audible device or siren. This may sound similar to an actual police siren, or it might be something more silent. One example of an audible personal alarm is the sleep bracelet, which sounds an aggravated warning when its battery life runs down. Other examples of common audible alarms include cell phone sirens and flashlight alarms. Some personal alarms will also incorporate a silent beacon, which allows the wearer to contact emergency services in the event of an emergency without sounding the alarm.
Another important component of a personal safety device is the emergency contact information displayed on the device. This includes a number that either calls attention to itself or another contact, or allows the wearer to contact emergency services directly. Some examples include an 800 number, a hot line, or an email address that sends a message that is broadcast to everyone in the area. Other options allow for the use of pre-programmed texts, which are useful if you forget the name of the emergency contact person, or if you are in a location where you can't reach them easily.
The final feature is battery life. Most personal alarms offer at least a thirty-minute battery life, although some can work up to three hours. Still, you want to make sure that you get enough battery life in case of a power outage. Some personal safety devices last up to three days with just one charge, while others require you to replace the batteries every day.
As you can see, there are many different features available in smart personal security devices. Some of them have specific functions, while others work as general security devices that alert you to potentially dangerous situations. There are, of course, other types of smart security devices, including home intercom systems and window and door sensors. You can research the Internet to find more about each type, and decide whether you need to invest in one or another type of personal safety device.
