Product Q&A

Q:Why does the device beep everywhere?

High sensitivity may pick up distant signals like Wi-Fi routers or base stations. Calibrate sensitivity before use. Also, turn off local interference sources like Bluetooth devices or microwaves for a cleaner sweep.

Q:What is counter surveillance?

Counter surveillance, or bug sweeping, involves measures to prevent surveillance, including electronic detection using RF Bug Detectors, Camera Detectors, and GPS Tracker Detectors to protect privacy.

Q:Can I get a sample before bulk order?

Yes, samples are available for all models. However, the buyer is responsible for sample costs, shipping fees, and any applicable taxes.

Q:What if I don't know the frequency in my country?

Please contact us with your inquiry. We will help identify the required frequency for your region and assist in resolving any related issues.

Q:Can I customize frequencies or accept OEM/ODM orders?

Yes, we customize brand logos and frequencies. We support customization for various signals including GSM, 5G, WiFi, Bluetooth, GPS, and more.
