Rapid technology growth provides new, innovative ways to enhance the quality of your life, including personal safety. From mobile apps to wearable devices, keeping up with the latest technology trends can help you protect yourself in an emergency. Below are four personal safety tech solutions to consider purchasing.

1. Smart Pepper Spray

Pepper spray, also known as “OC spray,” is one of the most common and well-known self-defense devices. Many carry it in their purses, pockets or on key chains to protect themselves from attackers.

In fact, one company has transformed this ordinary defense tool into a smart device. Smart pepper spray is designed to summon help the moment it’s fired by automatically alerting emergency contacts through a smartphone app. Then, the connected pepper spray notifies designated contacts when the user is in danger, while also triggering audible and visual alarms to further help deter an attacker.

The result? More immediate response to crime scenes and an increased chance of catching the assailant.

2. Watch Over Me App

People use mobile apps for entertainment on a daily basis, so why not use one for security? The Watch Over Me app is available for both iOS and Android, and helps keep tabs on people while they:

  • Meet up with friends
  • Rideshare
  • Run or walk
  • Walk home or to their cars

Set the estimated time it will take to complete an action, and press the “Watch Over Me” button. Once activated, a timer begins that runs until arrival is confirmed.

If you do not confirm your safety within the entered time frame, the app will alert your designated contacts through SMS, email or Facebook that you are potentially in danger. After that, the app sends an alert from your GPS, notifying friends and family of your exact location.

3. Smart Jewelry

Some home security systems feature panic buttons users can press to send for help during an emergency. However, these devices aren’t effective if you need help when you’re away from home. That’s where smart jewelry comes in.

Smart jewelry pairs with an app on your smartphone. With a double-click of the button on the back of the stylish pendant, users can send an alert to selected family and friends, giving them your GPS location and letting them know you need help. If you don’t respond to a checkup alert, the app will call the authorities with your location.

4. Geofencing

Geofencing capabilities allow you to control your home from afar. The GPS on your smartphone defines geographical boundaries, which trigger the automation of:

For example, arm your security system whenever your phone is more than one mile away from your home, or turn on your lights whenever you’re pulling into your driveway. This control enhances protection and adds convenience.
