VS-JD101 Jamming Signal Detector by SZ Vodasafe
Description:
The VS-JD101, developed by SZ Vodasafe, is a professional-grade jamming signal detector engineered to safeguard fleet management and GPS tracking systems. Leveraging advanced fuzzy scanning technology, this device efficiently detects jammer signals across a broad frequency range of 50 MHz to 6.0 GHz. Notably, it operates without interfering with essential wireless communications, including cell phones, WiFi, WLAN, Bluetooth, and DECT phones.
Features:
Advanced Signal Detection
Fuzzy Scanning Technology: Enables precise identification of jamming signals while minimizing false positives.
Wide Frequency Range: Covers 50 MHz to 6.0 GHz, effectively detecting common cellphone, WiFi, and GPS jammer signals.
Signal Strength Indication: Utilizes a 10-LED array to visually represent detected signal strength, transitioning from green to yellow to red as signal intensity increases.
Intelligent Environmental Adaptation
Environment Noise Verified Circuit: Reduces false alarms by filtering out background noise.
Sensitivity Tuner: Allows manual adjustment to eliminate environmental interference. Factory-set at a 5-minute clock position for optimal performance in most scenarios.
Noise Adjustment Switch: Located in the battery compartment with "H" (High) and "L" (Low) settings. The default "L" setting is suitable for standard environments, while "H" can be used in high-noise areas to minimize false triggers.
Flexible Relay Output System
Dual SOS Trigger Modes:
Mode 1: Hold the SOS button for over 3 seconds to activate automatic dialing.
Mode 2: Press and release the SOS button after 3 seconds to trigger dialing.
Relay Configuration:
NO (Normal Open): Ideal for standard emergency button circuits (brown and red wires).
NC (Normal Close): Connects to GPS power input for quicker triggering, bypassing the 3-second delay (orange and red wires).
1.0A Relay Output: Supports both NO and NC configurations for compatibility with various GPS tracker brands.
Robust Construction and Safety
Compact Design: Measures L 130 x W 68 x T 26 mm (5.1" x 2.7" x 1"), weighing approximately 195g for easy integration.
Wide Power Compatibility: Operates on 12V-24V DC at 150 mA, suitable for automotive applications.
Durability Features:
Water-resistant design (avoid direct exposure).
Heat-resistant construction (do not store in excessively hot environments).
Impact-resistant housing (protect from knocks and drops).

Operational Guidelines
Installation Steps
Connect the power input wires (red = +, black = -) to the vehicle's VCC and GND, ensuring correct polarity.
Verify proper operation: The leftmost green LED and the trigger indication LED (upper right) should illuminate.
Signal Detection Process
When a jammer signal is detected, the 10 LEDs will light up sequentially from green to red based on signal strength.
Upon confirming a jammer signal, the relay output triggers the GPS tracker's SOS button to send a help warning. The trigger indication LED will turn off during this process.
Relay Wiring Guide
First GPS Tracker Type (NO Connection):
Connect brown (NO) and red (COM) wires to the emergency button circuit.
Second GPS Tracker Type (NC Connection):
Connect orange (NC) and red (COM) wires to the GPS VCC and GND circuit.
Sensitivity Adjustment
Turn the Sensitivity Tuner to "-" to decrease sensitivity (shorter detection distance).
Turn to "+" to increase sensitivity (longer detection distance). Only adjust if necessary due to strong environmental noise.
