Under Vehicle Scanner vs Mirror Inspection: Which is Better for Vehicle Security?

Posted by Secure India | Updated: July 10, 2025


Securing the undercarriage of incoming vehicles is vital at high-risk locations such as military zones, airports, embassies, and commercial complexes. Traditionally, manual mirror inspection was the norm. Today, advanced Under Vehicle Scanning Systems (UVSS) are replacing this outdated method.

Let’s compare both approaches to help you decide which one suits your facility's needs.

What is Mirror Inspection?

Mirror inspection uses a handheld mirror attached to a pole, allowing guards to look under the vehicle manually. It's a cost-effective but limited way to detect hidden threats or contraband.

What is an Under Vehicle Scanner (UVSS)?

A UVSS is an automated system that captures high-resolution images of a vehicle’s undercarriage in real-time as it passes over the scanner. It uses AI and image comparison tools to flag anomalies instantly.
