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?
A:
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?
A:
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?
A:
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?
A:
Up to 6 meters, far exceeding most entry-level nonlinear junction detectors on the market.
Q:How long does the battery last?
A:
Over 3 hours of continuous use at maximum pulse power, enough for a full single-site sweep.
