Key Features
- Advanced Hidden Camera & Bug Detection: Provides comprehensive surveillance detection for hotels, offices, rental properties, and vehicles.
- Multi-Functional Privacy Protection with Magnetic Detection: Equipped with hidden camera detection, bug detection, and magnetic field detection (K68+) to identify covert tracking devices.
- Easy Operation with Smart Alerts & Adjustable Sensitivity: Features LED signal strength indicators and customizable alert modes (sound and vibration). Sensitivity can be adjusted for precise detection.
- Compact, Portable & Durable Design: Lightweight and easy to carry, suitable for travelers and professionals.
- Comprehensive Security for Any Environment: Offers full privacy protection against hidden threats in various personal and professional spaces.
Setup
- Charging the Device: Before first use, fully charge both the K68+ and K18+ detectors using the provided USB-C cables. The charging indicator will typically change color or turn off when fully charged.
- Attaching Antennas/Probes: For RF signal detection, securely attach the antenna to the designated port on the device. For magnetic field detection (K68+), attach the flexible magnetic probe.
- Power On: Press and hold the power button on each device until it turns on.
Operating Instructions
K68+ Detector Operation
- Hidden Camera Detection (Infrared Scan):
- Activate the infrared scanning mode.
- Look through the red viewing window on the device.
- Slowly scan the area. Hidden camera lenses will appear as bright red dots.

- RF Signal Detection:
- Ensure the RF antenna is attached.
- Turn on the RF detection mode.
- Adjust sensitivity using the dial. Start with lower sensitivity and increase as needed.
- Move the device around the area. The LED signal strength indicator will illuminate, and an audible or vibratory alert will activate when an RF signal is detected. Higher signal strength indicates closer proximity to the source.
- Magnetic Field Detection:
- Attach the flexible magnetic probe.
- Activate the magnetic detection mode.
- Scan surfaces, especially in vehicles or under furniture, where magnetic trackers might be placed. The device will alert you to the presence of strong magnetic fields.

K18+ Detector Operation
- Hidden Camera Detection (Infrared Scan):
- Activate the infrared scanning mode.
- Look through the green viewing window.
- Scan the environment slowly. Hidden camera lenses will reflect the infrared light and appear as bright green dots.

- RF Signal Detection:
- Ensure the RF antenna is attached.
- Turn on the RF detection mode.
- Adjust sensitivity as needed.
- Move the device around. The LED signal strength indicator will show the presence and intensity of RF signals.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or abrasive materials.
- Storage: Store the detectors in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: Recharge the devices regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
Troubleshooting
- False Alarms: Reduce sensitivity if the device is constantly alarming without a clear source. Environmental RF noise (e.g., Wi-Fi routers, cell phones) can trigger alerts.
- No Detection: Ensure the device is fully charged and turned on. Check that the correct detection mode is selected and sensitivity is appropriately adjusted.
- Weak Signal: Move closer to the suspected area or increase sensitivity. Ensure no obstructions are blocking the signal path.
