SISCO portable GPS bug detector integrates a high-sensitivity linear magnetic sensor and infrared spectrometer to capture both magnetic fields and optical reflections from surveillance devices. It provides visual, sound, and vibration feedback, with a wide dynamic range for pinpointing GPS transmitter signals and a compact, long-lasting power design.

Broadband RF Signal Detection

Infrared Optical Scanning for Hidden Cameras
SISCO portable GPS bug detector is ideal for hotel rooms, rental cars, corporate meeting rooms, and private homes to quickly screen for hidden GPS trackers, wireless eavesdropping devices, and covert cameras. It also protects business negotiations, gym locker areas, and personal vehicles from unauthorized surveillance. Its compact size allows everyday carry, giving you instant privacy checks in any unfamiliar setting.

Q1: What types of surveillance devices can this Portable GPS Bug Detector pick up?
A1: It captures active GPS trackers, wireless listening bugs, hidden cameras (via infrared), and other RF transmitters operating within 3MHz-8.5GHz. The magnetic sensor also helps locate GPS transmitters by their field signature.
Q2: Does the infrared scanner work in total darkness or bright sunlight?
A2: Yes, the IR spectrometer detects lens reflections independent of ambient light. Dynamic background subtraction automatically adjusts to changing lighting, so you get reliable readings whether in a dark hotel room or a sunlit office.
Q3: How does the device alert me when something is found?
A3: It gives simultaneous audible beeps and vibration pulses, with real-time signal strength shown on the OLED screen. You can adjust sensitivity in four steps to reduce false alarms, and rotating the unit helps you directionally track the source.
Tips: What is the quickest way to trace a signal source once the detector gives an alert?
Immediately reduce sensitivity to the lowest usable level, then rotate the device slowly in a full circle while watching the OLED bar graph. The strongest reading indicates the transmitter’s direction. Move a few steps toward that bearing, repeat the rotation, and continue narrowing down the hot spot. This triangulation method, combined with the magnetic sensor, helps your Portable GPS Bug Detector precisely locate hidden GPS trackers and wireless bugs within minutes without needing any external antenna.
