VT-801 Advanced Non-Linear Junction Detector for High-End Privacy Protection
The VT-801 finds electronic devices that are switched off. It emits an S-band fundamental signal and reads the second and third harmonics that semiconductors return, so a recorder hidden in a wall, ceiling, light fitting or piece of furniture shows up whether or not it is transmitting. An AI algorithm analyses the harmonic pattern to keep the false alarm rate down.
Key benefits
- Detects devices that are powered off and not transmitting
- Second and third harmonic detection identifies semiconductor content
- AI analysis of harmonic patterns for a low false alarm rate
- Visual, vibration and sound alerts for locating a target
- Complies with HJ/T10.2 radiation environmental protection guidelines
Problems it solves
- RF sweeps find nothing when the device is powered off
- Devices concealed inside walls or furniture cannot be found visually
- High false alarm rates make a sweep unusable in a furnished room
- Metal detectors cannot distinguish a recorder from a screw
Who it is for
- Corporate security teams protecting commercial confidentiality
- Facility auditors covering sensitive or restricted areas
- Individuals and hotels checking rooms for surveillance devices
Application scenarios
- Corporate meeting rooms and confidential offices before a sensitive discussion
- High-security facility and safety audits of sensitive areas
- Residential and hotel sweeps for hidden cameras and recorders
- Checking furniture, walls, ceilings and containers
Technical features
- S-band fundamental transmission with second and third harmonic reception
- Embedded artificial intelligence harmonic analysis
- Non-destructive detection algorithms to reduce false alarms
- Complies with Ministry of Public Security standard GA1236-2015
- Tested by the National Quality Supervision and Inspection Center for Safety and Alarm systems

Figures are those published by the factory for this model. Where a value is shown as TBC it is not published, and we will confirm it with the factory before you order rather than estimate it.
Quality control
- Certified by the National Quality Supervision and Inspection Center for Safety and Alarm systems
- Compliant with Ministry of Public Security standard GA1236-2015
Compared with other models in the range
The VT-802 is the compact portable version of the same detection principle at around 0.52 kg. The VT-811 adds a wireless signal detection unit that also picks up 5G at 2.6, 3.5 and 4.9 GHz. The VT-801 is the full-size instrument with a 4 W transmitter and roughly 4 hours of operation.
Use guide
- Charge for a full operating session, roughly 4 hours of use
- Sweep walls, floors, ceilings, light fittings and furniture systematically
- Work from the harmonic response rather than expecting an RF signal
- Use vibration alerts when a sweep must stay silent
- Re-check any position that alarms from a second angle before concluding

VT-801 Advanced Non-Linear Junction Detector for High-End Privacy Protection FAQ
Will it find a device that is switched off
Yes. That is the point of non-linear junction detection: it responds to the semiconductor, not to a transmission.
How long does the battery last
Approximately 4 hours, from a 7.4 V pack.
Is it safe to use around people
The device characteristics comply with HJ/T10.2 radiation environmental protection guidelines.
What standard does it meet
Ministry of Public Security standard GA1236-2015 for nonlinear junction detectors, with testing by the National Quality Supervision and Inspection Center for Safety and Alarm systems.
What language is the interface
The source specification describes a Chinese interface. Ask us on WhatsApp about localisation before you order.
How heavy is it to sweep a room
1.52 kg for the unit, with a 0.05 kg probe.
How does it compare with the VT-811
The VT-811 adds wireless signal detection including 5G bands. The VT-801 is the harmonic-only instrument.
