Sky Alert


The Sky Alert SOS Fob is a 4G personal security device that harnesses cutting-edge technologies. With Global Positioning System (GPS), a user’s location can be pinpointed to within 8.5 feet. Communications technologies allow users to speak directly to staff at our monitoring stations 24 hours a day, 7 days a week. In-built motion and shock sensors ensure the device can detect a lack of movement or sudden impact, which may indicate a user needs help.

We’ve worked hard to choose an SOS Fob that’s super-practical. It’s discreet, durable, lightweight, and waterproof (IPX6 rated). Its battery has an extended life, and the device can be quickly and easily recharged. As it’s wearable using a variety of neat accessories, the SOS Fob can be carried wherever and whenever it’s needed.
