One of the basic functions of a GPS locator is whether to support the power failure alarm. The power failure alarm is to prevent car thieves from powering off the battery in the vehicle when stealing the car. If the locator does not have this power failure alarm function, In this case, it will fail. Therefore, the power failure alarm is one of the functions of the GPS locator.

An anti-theft device without a built-in battery can easily fail to work. In addition to a power failure alarm, the GPS locator must also have a built-in battery to prevent the vehicle battery from maintaining normal operation when it is out of power. Many low-end GPS locators do not have this function, and many people do not pay much attention to this function when buying GPS locators. Although this function is not very important, it can guarantee the situation when the vehicle battery is dead. One of the means for the normal operation of equipment.
