James Whitaker

Technical Security Officer

“PHC12 rf detector works well in mixed RF environments. We used it during a sweep of a meeting facility and it picked up and separated signals faster than expected. The thermal view is useful when you’re trying to confirm whether something is actually active or just background noise.”

Markus Schneider

Site Security Inspector

“We mainly use it during night rounds or low-light checks. It’s good for quickly spotting unusual heat spots without opening panels or doing manual checks first. Nothing complicated, just point and scan.”
