Overhaul Says Its New Tamper Detection Alerts When a Trailer Door Opens, Even if the Seal Looks Intact

By Big Rig Daily Staff

Cargo thieves have found ways around even electronic seals, and a company says its new system can tell the moment a trailer door is opened. Overhaul launched what it calls Gen2 Tamper Detection Technology, The Trucker reports.

The problem it targets

A seal has long been the stand-in for whether trailer doors stayed shut. But an intact seal is not proof that nobody got in. Thieves have reportedly found ways to reach a load without disturbing the seal, and teams often do not learn there was a problem until a manual check or delivery, according to Overhaul.

What the company says it does

According to Overhaul's announcement, the system is meant to:

• Alert in near real time when a door is opened, no matter what the seal looks like
• Work on containers, trailers and roll-up doors
• Handle multi-stop runs

The company says that in pilot testing, the system detected every door opening. That result comes from Overhaul and has not been independently verified.

Who can use it

For now, it is available only to Overhaul customers. The company says it is keeping deployment details confidential so thieves cannot adapt. Overhaul says it will share details only in confidential customer briefings.

"A seal has always been a proxy for the door itself, and we've seen criminals find ways to overcome even electronic seals," said Nick Heikkinen, Overhaul's vice president of IoT technology and operations. He said a number of the company's largest customers have already signed up.

Why it matters to truckers

When a load is found short at delivery, the trucker is often the first one questioned. A record of exactly when a door opened could help sort out what happened, if the technology works as the company says. Cargo theft remains a major concern, as seen in recent cases of fake carriers and stolen MC numbers.

A question for readers

Truckers, if the seal still looks intact at delivery, would you trust it, or want an alert the second those doors moved?
