AlterLock is an alarm/GPS tracking security device for bikes. It lets you keep a remote eye on your bike and notifies you on your phone when the device detects movement while the bike is locked away.
If the AlterLock device detects motion from your bike while in Lock mode, it will blare out an alarm that is as loud as 95dB, which is louder than a lawnmower, almost just as loud as a helicopter.
When motion is detected, the AlterLock app will notify you on your phone with its own notification sound, so you can distinguish it from other notification sounds like email and realize you need to get to your bike straight away.
In the unlikely event that your bike is stolen, AlterLock can track it once a minute all the way to its final destination. If the bike is moved indoors where there is no GPS signal, the device uses Wi-Fi signals to determine its approximate location. This can also provide clues if the bike is abandoned or when the police search for it.
