There are several categories of alcohol monitoring technology, each built for a different purpose.
Continuous transdermal monitoring (SCRAM ankle bracelets) detects alcohol through the skin 24/7 and is almost always court-ordered.
Ignition interlock devices are installed in vehicles and are typically court-approved after DUI cases.
Electronic monitoring that uses in-person testing or clinic visits is common in probation and treatment programs.
Remote alcohol monitoring with portable breathalyzers (the category BACtrack View and Soberlink sit in) uses scheduled and random breath tests with a handheld alcohol monitoring device. This is the only category that works well for voluntary, self-directed use, because it preserves privacy and dignity while still producing verifiable test results.
BACtrack View uses HD video verification instead of still-frame facial recognition photos. Every breath test is recorded on video through your smartphone camera, so there is never a question about who provided the breath sample. For personal accountability, that means the record you are building is strong enough to hold up in any conversation, including the one you have with yourself.
