Anti Spy Scanner with 1-8000MHz RF Signal & Hidden Camera Detection

Finding hidden surveillance devices is not always about seeing something suspicious. The harder part is detecting what cannot be seen — weak RF signals, hidden magnetic trackers, or tiny camera lenses placed in ordinary objects.

With its wide 1-8000MHz radio frequency detection range, the K-68 detector accurately detects wireless transmission devices such as GSM/4G/WiFi/Bluetooth/GPS.

You can purchase our portable 31-band full spectrum signal jammers for signal jamming.

Its three-dimensional probe structure helps it penetrate obstacles such as walls, furniture, and interior decoration materials to capture signals.

The knob clockwise to turn on the device. Set the sensitivity to level 3-4, and the device will enter probe mode. It offers three notification modes:

• LED indicator
• sound
• vibration

The closer the signal scanner is to the signal source, the stronger the response, helping users to roughly determine the location of the signal source.

The signal strength indicator uses 4 detection zones with 10 signal levels:

• Zone 1 — Safe Area

After startup, the display shows a white signal, indicating no obvious suspicious signal detected.

• Zone 2 — Initial Detection

When a possible signal appears, the display flashes in the green area and provides sound alerts.

• Zone 3 — Stronger Signal Area

As the device approaches the source, the indicator moves into the yellow or red area.

• Zone 4 — Signal Source Location

When very close to the source, the display enters the red zone with the strongest warning indication.



Of course, it does not rely on a single detection method; it has three probe modes.

• Electromagnetic Signal Detection

Real-time scanning of abnormal RF emissions

Sensitivity reaches -110dBm

Helps identify possible wireless bugs, hidden transmitters, and monitoring devices

Suitable for detecting devices that remain in standby mode

• Magnetic Tracker Detection

Some tracking devices rely on magnetic installation rather than constant wireless transmission.

The K-68 includes:

Flexible detection probe

Built-in gauss meter

Magnetic field scanning capability

It can help inspect areas such as:

Vehicle chassis

Under-seat areas

Metal surfaces where magnetic GPS trackers may be attached

• Optical Camera Lens Scanning

The optical scanning system uses:

8 LED light arrays

Adjustable focus function

Optical filtering technology

By using lens reflection principles, the K-68 helps identify hidden pinhole cameras, including cameras that are switched off but still reflect light through the lens.
