What Is It?
The patented SCRAM ankle bracelet – the heart of the SCRAM system – is attached to the offender with a durable and tamper-proof strap. It is worn 24/7 by the offender for the duration of his or her court-ordered abstinence period (typically 90-120 days).
Twice an hour, the bracelet captures transdermal alcohol readings by sampling the insensible perspiration collected from the air above the skin. The bracelet stores the data and, at pre-determined intervals, transmits it via a wireless radio-frequency (RF) signal to the SCRAM modem.
