A pre-warn vehicle security device is for a vehicle including a data communications bus, an alert indicator, and an alarm controller interfacing with the data communications bus. The alarm controller may cause the alert indicator to generate an alarm indication responsive to a high security threat level. More particularly, the pre-warn vehicle security device may include a housing and a multi-stage sensor carried by the housing. The multi-stage sensor may sense the high security threat level and communicate the sensed high security threat level to the alarm controller via the data communications bus. It may also sense a low security threat level lower than the high security threat level. Moreover, the pre-warn vehicle security device may also include a pre-warn indicator carried by the housing and connected to the multi-stage sensor for generating a pre-warn indication responsive to the sensed low security threat level. <IMAGE> |
