How to choose the best RF bug detector

While selecting your best RF bug detector, there are a number of factors you need to consider:

Discreetness of Device

If you need to be inconspicuous while carrying a bug detector, you need to choose one that has earphone support, vibration mode and a retractable antenna. These features assist you to have a private sweep.

Red-Light Filtering

Some cameras shut down and cannot emit signals hence remaining undetectable. You will want to go for a bug detector that has red-light laser. Cameras that don’t send frequencies emit glares under a red light detector.


Most entry-level bug detectors are meant for private use. However, if you are a professional, you will need to invest in sophisticated bugs that are designed with frequency and sensitivity as a priority.

Two Devices

You can opt to have two bug detectors; one that tracks radio frequencies and another that has the red-light laser for cameras that are inactive.

Power Supply

You should go for bug detectors that are powered by common batteries to allow a quick recharge.

Ability to track other devices: Go for bug detectors that can detect a wider variety of bugs like GPS trackers, mobile phones, CDMA or audio bugs.
