• Sensitivity Adjustment: Adjustable sensitivity is crucial to avoid false alarms from vibrations like wind or passing traffic. More levels give you finer control over when the alarm triggers.
• Waterproof Rating: If your work truck is exposed to rain or harsh weather, choose an alarm with an IP rating like IP55 or IP66 to ensure reliable performance in all conditions.
