Is professional training required?

No. Clearly labeled buttons and an intuitive LCD display allow new operators to use it with minimal training.

What alert modes does it have?

Three modes--real-time LCD signal readout, audio tone (speaker or headphone), and silent vibration for discreet sweeps.

Does it have official certification?

Yes. It is certified to China's GA1236-2015 Class C standard, the top rating for civilian and law-enforcement NLJD equipment.

Key features

Detects Powered-Off Electronics--Locates hidden cameras, audio bugs, GPS trackers and recording devices even when switched off and emitting no RF signal.

Class C Certified Performance--Officially certified to GA1236-2015 Class C standard, the top civilian/law-enforcement rating for NLJD equipment.

370mm Wall Penetration--Reliably detects semiconductor devices concealed inside solid brick walls, floors, ceilings, furniture and containers.

6m Long Detection Range--Maximum effective detection distance of 6+ meters, far exceeding entry-level nonlinear junction detectors.

Ultra-Compact & Lightweight--Foldable handheld body weighing only 0.5kg, fits in a backpack or uniform pocket for one-hand operation.

Triple Alert System--Real-time LCD signal readout, audio tone via speaker/headphone, and stepless vibration for silent covert sweeps.

-125dBm High Sensitivity--Captures weak harmonic returns from tiny microchips, miniature recorders and ultra-small tracking devices.

3+ Hour Battery Life--Built-in rechargeable lithium battery delivers over 3 hours of continuous use at maximum pulse power.

2nd & 3rd Harmonic Analysis--Distinguishes true semiconductor junctions from metal corrosion, significantly reducing false alarms.

Professional TSCM Grade--Trusted by government, law enforcement, corporate security and anti-espionage sweep teams worldwide.

Product Q&A

Q:What devices can the VS-820 detect?

It detects all semiconductor-based electronics--hidden cameras, audio bugs, GPS trackers, mobile phones, recording devices and electronic trigger circuits.

Q:Does it work if the hidden device is turned off?

Yes. Unlike RF detectors, it finds electronics whether they are powered on or off, and even when they emit no signal.

Q:Can it see through walls?

Yes. It reliably detects devices concealed inside up to 370mm thick solid brick walls, floors, ceilings and furniture.

Q:What is the maximum detection range?

Up to 6 meters, far exceeding most entry-level nonlinear junction detectors on the market.

Q:How long does the battery last?

Over 3 hours of continuous use at maximum pulse power, enough for a full single-site sweep.
