FAQ
What is the key FMVSS standard affecting remote immobilizers?
FMVSS 302 is the key standard, which addresses material flammability inside the cab. Any aftermarket control module installed under the dash must be built with materials that won't become a fire hazard, and many off-the-...

How often should fatigue sensitivity settings be reviewed and adjusted?
Settings should be reviewed quarterly and after any major operational changes such as new routes, shift schedules, or vehicle types. Seasonal changes are particularly important to address, as daylight variations can sign...

What is the recommended process for finding the right sensitivity balance?
Start by reviewing existing footage and flagged events to identify patterns. Tweak sensitivity in small increments, test for a week, then adjust again. Use custom reporting tools to analyze data by vehicle, shift, or dri...

Why is using the same sensitivity setting for all vehicles and drivers problematic?
Applying uniform sensitivity across different vehicle types and drivers creates two major problems: drivers start ignoring all alerts due to false alarms, and managers stop reviewing reports because they're filled with j...

What are the main factors that affect AI dashcam fatigue sensitivity accuracy?
Lighting conditions are a major factor - sun glare can cause false alerts when drivers squint, while dark conditions at night might miss real fatigue events. Driving environment also matters, with different sensitivity n...

How can I reduce alert fatigue for my dispatchers?
Implement alert delays (e.g., 2-minute trigger), widen corridors in problematic zones, and create prioritized alert tiers so only critical deviations create immediate notifications. Analyzing false alert clusters and adj...

Can route deviation geofencing detect quick, unauthorized stops?
Only if the stop duration exceeds the system's 'dwell time' threshold and occurs outside a designated stop geofence. Short stops between GPS pings may be missed due to data transmission latency (typically 5-30 seconds),...

How wide should I set my geofence corridors to avoid false alerts?
Corridor width should vary by environment. Start with 200-300 meters in urban areas and 100 meters on highways, then adjust based on your alert history. Setting corridors too narrow for the area is a common failure patte...

Why do I get false route deviation alerts in urban areas?
False alerts in cities are often caused by GPS signal bounce off buildings, known as 'urban canyon' drift, which can make a vehicle appear 50 meters off its path when it's actually in the correct lane. This problem is am...

What is route deviation geofencing and how does it work?
Route deviation geofencing creates a dynamic corridor (typically 100-500 meters wide) around a sequence of planned geofences or GPS breadcrumbs. The system triggers an alert when a vehicle's GPS signal leaves this corrid...

How can I test if my towing detection system actually works?
Safely simulate a tow by having a team member move the vehicle a short distance with the ignition off. Monitor your dashboard and email/SMS notifications to see if a real-time alert triggers. This practical test helps ve...

Do I need a different device for reliable ignition-off tracking?
Yes, you need a device with a built-in accelerometer (motion sensor) and a reliable power source, such as a hardwired connection to the vehicle battery or robust solar setup. Many entry-level systems lack this capability...
