This mobile phone detection system consists of two sensor poles (Dipole). Each pole has six equally spaced sensors connected to a micro-controller.
Detected data are spontaneously wireless transmitted to a Main Controller. Data are further analyzed by the main controller to determine if a mobile phone has passed through these Dipole.
When a person walk through the Dipole with a mobile phone, signal strength (above the background noise level) of each detector is displayed on Main Controller's LED panel instantaneously with respect to its position.
In the mean time, main controller will sound alarm, active dry contact, or establish wireless or TCP/IP communication with a remote computer depends on customer's preference.
Dipole is very lightweight and easy to set up. Since it is a reactive system, dipole does not generate any harmful strong RF driver signal.
Dipole and the main Controller consume very low power suitable for non-stop operation.
System does not need any operator to monitor like a metal detector.
Moreover, Upgraded Idle Standby Phone Walk Through Detector RFD-10PL (TCP/IP Plus) can work with one or multiple IP cameras for remote monitoring and warning.
When someone with a phone walks through RFD-10PL cell phone door detector, you will get sound and image alerts quickly. A photo capture pops up to show you who has a phone on our software interface. IP camera's address and time stamp also on the photo. Only the detected photos are stored in the recorded files so you can efficiently find out who have phones without replaying all recorded videos of the IP cameras.

Real-World Exam Anti-Cheating Application Insight

In modern exam security operations, unauthorized communication is rarely dependent on wearable devices alone. In practice, smartwatches and similar devices rely on a connected smartphone, which is the actual communication hub.
For example, a smartwatch typically communicates through Bluetooth or a paired mobile phone. However, Bluetooth transmission power is extremely low (typically 0.01–1 mW), making it unreliable for consistent detection in real-world environments. When the smartwatch is not actively connected or transmitting data, there is often no detectable signal at all.
For this reason, professional exam security systems focus on detecting the actual source of communication: the smartphone.
Smartwatches depend on smartphones that continuously emit stronger cellular signals across 2G, 3G, 4G, and 5G networks. These cellular uplink signals are the most reliable indicators of unauthorized communication activity in exam environments.
The RFD-10EU is specifically designed for this operational principle, enabling security teams to detect hidden or active mobile phones within approximately 10–15 meters, making it a practical and proven solution for exam anti-cheating enforcement.

What Can the RFD-10EU Detect?

The RFD-10EU is designed to detect active cellular signal transmissions, including:

• Mobile phones during calls, data transmission, or network activity
• Smartphones with cellular communication enabled
• Hidden communication devices using cellular signals
• 3G / 4G / 5G wireless covert cameras

Important: Devices that are completely inactive with no signal transmission cannot be detected.
This model is designed for cellular signal detection only and does not include Wi-Fi detection.

Typical Application Scenarios

• Prison contraband mobile phone detection
• Exam anti-cheating enforcement
• Law enforcement inspections
• Military and government security checks
• Corporate anti-espionage operations

FAQ

Can the RFD-10EU detect phones in standby mode?

The RFD-10EU detects cellular signal activity. If a phone generates background signals (such as periodic network communication), it may be detected. However, if the device is completely inactive with no signal transmission, it cannot be detected.

What is the detection principle of the RFD-10EU?

The RFD-10EU detects uplink cellular signals from mobile devices across 5G, 4G, 3G, and GSM frequency bands.

What makes RFD-10EU different from other RF detectors?

• 5G EU band support (3400–3800 MHz)
• Adjustable sensitivity for each frequency band
• Real-time signal strength display (signal bar per band)
• Professional-grade accuracy for security applications

These features allow users to fine-tune detection performance and improve locating efficiency in complex environments.
