The BrickHouse Security 4G LTEEON 4 GPS Asset Tracker utilizes both GPS and Wi-Fi capabilities, keeping it functional both indoors and out. The EON boasts accurate location data whether your target is moving or standing still. Whether you're monitoring a truck in the field or assets around inside the warehouse, you receive motion updates every fifteen minutes when this device senses movement. Don't worry about the battery running out! The EON utilizes 4 AA lithium batteries to provide extra-long battery life, perfect for tracking a shipment on the go. These batteries are easily replaceable, but they are powerful—they can last up to 5 years if you set your device to send updates every 12 hours! EON is IP-67 rated - so it is resistant to both dust and water.
