Code Alarm MV3 Dual Zone Microwave Sensor

Can be adjusted to detect movement around your vehicle (Zone 1): Generally the optimal setting is when you adjust the exterior setting to sense when someone is close enough to look into the drivers window. So basically the sensor is set to detect any perimeter movement between the side view mirror and the drivers door window. This is considered zone 1, and upon perimeter intrusion of zone 1, the sensor will send a negative signal to your systems zone 1, stage 1 or warn-away input (depending on how your specific system describes it) that will cause your alarm to momentarily sound the alarm but not fully trigger it. Can be adjusted to detect movement into your vehicle (Zone 2): Generally the optimal setting for zone 2 is when you adjust the interior setting to sense when, for example, you left your window down (or top down for convertibles) and someone reaches in to grab something and by the time they reach in up to their elbow the sensor will send a signal to your system's zone 2 wh
