Overview
JMDHKK builds this detector as a pocket box with a probe, a charging cable and a wireless antenna. It runs on a battery, pairs with a smartphone over Bluetooth, and is aimed at checking offices, rooms and hotel stays.
Travelers and renters who want to check a room before settling in get a small device that fits a bag. The limitation is documentation: the listing gives the video specs but no detection range for the radio and magnetic checks that matter most.
Who it's for
A hotel room, a short-term rental or a private office is the usual setting. Professionals who need documented performance should use certified equipment instead.
Pros and cons
- Portable box with a tabletop mount
- Includes RF antenna and GS probe
- USB charging cable included
- Audio and motion alerts
- Detection range not listed
- Not water resistant
- Indoor use only
- Manual is the only guide listed
Performance notes
Detection relies on an RF antenna picking up wireless transmitters and a probe sensing magnetic fields, so results depend on how close the antenna is to the source. Sweeping slowly along walls and furniture gives the device time to react. The camera and night vision figures describe the unit's own video features, not its detection ability.
