There is a new Indiegogo campaign underway to fund a security device called the KeeperTI.  The KeeperTI would use a variety of technologies such as Bluetooth and WiFi to track tags that could be attached to your firearms, gun cases or other valuables.

The KeeperTI parameters can be adjusted to activate if an object is moved or if it is removed from a specified area.  Alarms can also be set to notify the user if a device enters a specified area.  Additionally, devices can be located using the tags.

Web-based and smart phone apps will control tracking and notifications.  Funding levels start at $9 and go up.
