Savi ST-675 Container Security
Tag Description
The Savi ST-675 tag is an active RFID container security tag with
intrusion and environmental sensors. The ST-675’s sensor arm detects the
open/closed state of the shipping container door, and the intrusion light
sensor monitors the amount of light entering the container. These
intrusion sensors detect potential theft or tampering. The temperature,
humidity, and shock sensors monitor environmental conditions to prevent
spoilage or damage to goods. In congested RF environments where tags
are polled repetitively, the ST-675’s over-polling detection and protection
algorithm preserves battery life.
