Figure 3-49. Advanced options.

Recording Source: Here you can choose either internal or external microphone.

Microphone Boost (+20 dB): Boosts the microphone by 20 dB.

Microphone Sensitivity: The level of sensitivity that can be set.

For example, if you set the level to 80, the microphone will detect more sound than if the level were set at 20. Pulse Length: This defines the minimum duration of a sound to trigger an alert notification.

Rearm: The Rearm parameter prevents the sensor from flickering between two states. For example, if the Warning High thresh- old for the sound sensor is set to 80 and the sensor temperature varies between 79 and 80, a very large number of e-mails, traps, and events would be logged. The Rearm parameter prevents this by forcing the signal level to drop by the Rearm value before changing the state back to normal. In this example, if Rearm is set to 2. then the sensor would have to drop from 80 down to 77 before the status would change from Warning High back to normal.

Data Collection Type: There are three settings for this parameter: lowest, highest, and average. Data will be collected for the lowest, highest, or average sound reading accordingly.

Advanced Status Text and Color: Here you can select to change your display text and warning colors.
