SZ Vodasafe PJ8100N High-Power Multi-Band Waterproof RF Signal Jammer
The SZ Vodasafe PJ8100N is an upgraded flagship professional waterproof RF signal jammer built exclusively for high-security critical sites including prisons, detention centers, confidential government compounds, military restricted zones and other sensitive supervision venues. Developed as an advanced iteration of the mature PJ6100N model, this unit expands the original channel configuration by adding two extra independent RF output channels, raising the total configurable channel count to 10 channels maximum. Every single RF channel delivers a stable 100W output power (±1dBm), doubling the single-channel jamming power of the VS-PJ6100N to deliver far stronger shielding capacity and wider coverage radius.
Equipped with a built-in full-function ETHERNET IP network monitoring interface as a standard configuration, the VS-PJ8100N supports remote centralized management, real-time equipment status monitoring and fault alarm push, which perfectly matches the construction demands of smart security supervision systems. Adopting rugged all-weather waterproof cabinet structure, advanced dual-fan independent heat dissipation system and comprehensive module self-protection logic, this high-power jamming system supports uninterrupted 24/7 long-term stable operation, and offers fully customizable frequency band schemes to adapt to evolving 2G/3G/4G/5G cellular, satellite positioning, Wi-Fi, Bluetooth and all mainstream wireless communication protocols, making it the premium choice for large-area, high-demand fixed-site signal isolation projects.
Core Competitive Advantages & Key Functional Features
1）Expanded High-Power Independent Channel Design
Different from the VS-PJ6100N’s 8–10 channels with 50W per channel, the VS-PJ8100N reserves 10 independent customizable RF output channels in maximum configuration, with each channel delivering consistent 100W RF output power within ±1dBm fluctuation. Each frequency channel is equipped with an independent physical control switch, allowing on-site operators to activate, deactivate or adjust single-band shielding functions flexibly according to actual supervision requirements, without shutting down the whole machine. The ultra-wideband professional interference technology is adopted, and the jamming signal only targets the downlink frequency band of public communication networks, which can effectively block all wireless signals inside the control area while avoiding adverse interference to nearby communication base stations and normal public communication services outside the shielding zone.
2）Standard Integrated IP Network Remote Monitoring System
A dedicated ETHERNET IP monitoring port is pre-installed as a standard functional interface on the control panel, breaking the limitation of local manual operation only on previous models. Users can connect the jammer to local area networks or private security networks via network cables to realize full remote intelligent management. Through matched monitoring background software, administrators can view real-time operating data of each channel, equipment operating temperature, fan running status, power load and VSWR standing wave parameters remotely; the system automatically triggers real-time alarm notifications once faults such as module overheating, abnormal output power or antenna disconnection occur, and supports remote independent switching of any single channel, batch switching of all bands, timing on/off task scheduling and historical fault record storage and query. This network monitoring function greatly reduces on-site inspection workload and realizes centralized unified management of multiple jamming devices distributed across large venues such as entire prison areas.
3) Full-Range Customizable Frequency Band Coverage
The VS-PJ8100N supports fully customized frequency spectrum matching according to project demands, covering all mainstream wireless communication frequency bands currently in use. The standard configurable frequency ranges include cellular communication bands covering 2G, 3G, 4G and 5G networks, with segmented frequency windows from 790MHz to 960MHz, 1800MHz to 1990MHz and 2110MHz to 2170MHz, as well as the 2496–2690MHz 4G/5G extended frequency segment. For satellite positioning and satellite communication signals, it covers the 1520–1630MHz band to shield GPS, GLONASS, GlobalStar and Thuraya satellite signals simultaneously. The 2400–2500MHz frequency channel is specially set for 2.4GHz Wi-Fi and Bluetooth wireless signals. If projects need to shield special customized frequency bands, the SZ Vodasafe engineering team can adjust the internal module configuration to realize exclusive spectrum customization without changing the host hardware structure.
4) Ultra-Wide Effective Jamming Coverage Range
Benefiting from the doubled single-channel 100W high-power output, the VS-PJ8100N achieves a much wider effective shielding radius compared with the VS-PJ6100N baseline model. Its stable jamming distance ranges from 50 meters up to 200 meters in actual deployment, and the specific coverage boundary will be adjusted according to the strength of external ambient communication signals, building barrier distribution and antenna installation height. When matched with supporting high-gain directional panel antennas, the equipment can eliminate signal shielding blind spots in large open areas, prison workshops, detention cell blocks and outdoor perimeter zones, achieving seamless full-area signal isolation.
5)Multi-Layer Automatic Self-Protection Mechanism
The whole machine is built with complete intelligent self-protection logic to avoid permanent hardware damage caused by misoperation or abnormal operating conditions. When internal modules generate overheating, over-limit power output or VSWR standing wave fault alarms (usually caused by loose antenna connections or damaged feeder lines), the system will automatically cut off the power supply of the faulty single channel module independently, instead of shutting down the entire device, so other normal frequency bands can keep working continuously. The circuit adopts slow-start power-on design, equipped with imported high-stability electronic components and highly integrated modular circuit layout, which effectively suppresses instantaneous current impact during startup and prolongs the long-term service life of the equipment under continuous working conditions.
6)IP-Rated All-Weather Rugged & Waterproof Structure
The host adopts a fully sealed industrial waterproof cabinet with IP protection grade, capable of adapting to harsh indoor and outdoor installation environments. The allowable operating temperature range spans from -10°C to +50°C, and it can stably operate under ambient humidity between 5% and 95% with non-condensing design, resisting rain, dust and temperature fluctuation in outdoor open-air deployment scenarios. The cabinet shell is made of thickened anti-corrosion metal material, with reinforced locking buckles on the cabinet door to prevent accidental opening and vandalism in public supervision areas.
7) Dual Independent Efficient Thermal Dissipation System
Two independent thermal fans (marked FAN1 and FAN2) are configured with separate dedicated power supply interfaces on the control panel, forming a dual-circulation heat dissipation structure matched with the large-area radiator on the side of the cabinet. The dual-fan design evenly takes away heat generated by 10 high-power RF modules inside the machine, completely avoiding heat accumulation during long-term continuous operation. The heat dissipation system will not cause performance attenuation of jamming power even under 24/7 non-stop running state, solving the overheating failure problem common in low-power single-fan jamming equipment.

According to the customized channel quantity of the equipment, a matching number of directional panel antennas will be delivered together, together with a 3-meter-long coaxial cable for each antenna to connect the antenna to the host RF output port. The full set of delivery packages also includes a detailed printed user manual and step-by-step installation guide, which records wiring standards, power-on sequence, fault judgment and daily maintenance specifications for operators to reference.
Standard Installation & Operating Procedures
Step 1: Unpacking & Component Inspection
Carefully open the outer packaging carton and take out the host cabinet, antennas, coaxial cables and power cord. Check all metal shells, cables and interfaces for extrusion, breakage or scratch damage during transportation; keep all original packaging materials intact for disassembly and transportation in later maintenance. If any accessory is damaged or missing, contact SZ Vodasafe technical support immediately before installation.
Step 2: Complete Pre-Power Wiring Connection
First, connect each directional antenna to the corresponding numbered DIN RF output port on the control panel using the supporting 3-meter coaxial cables one by one. Then plug the two cooling fans into the FAN1 and FAN2 dedicated fan power supply interfaces separately to ensure the heat dissipation system is fully connected. For projects requiring network remote monitoring, connect a network cable to the ETHERNET IP monitoring port and access the on-site security local area network. Only after all antennas, fans and network cables are fully wired can the main power cord be connected to the AC 220V input port.
Critical Safety Warning: Never switch on the power supply before all antennas and cooling fans are fully installed and connected. Power-on without antenna load will cause instantaneous RF power backflow, leading to rapid overheating and permanent burnout of internal RF modules, and such damage caused by misoperation is not covered by the product warranty.
Step 3: Power On & Channel Activation
After confirming all wiring is correct, connect the AC 220V mains power supply and turn on the main power switch of the host. Operators can manually toggle the independent channel switches on the control panel to activate or close specific frequency bands according to on-site shielding demands; administrators can also log into the remote monitoring background via the network port to complete remote channel switching, power status viewing and fault checking.
Step 4: Power Off & Dismantling Steps
Before cutting off the main AC power supply, turn off the switches of all RF channels first to stop RF signal output. Then disconnect the main power cord from the AC input port. If the equipment needs to be moved or maintained, disconnect the network cable, fan connectors, coaxial cables and antennas in sequence for storage.
Important Usage & Maintenance Notes
1.All directional antennas must be installed vertically perpendicular to the ground to guarantee the rated jamming gain and maximum effective coverage; it is strictly prohibited to remove or disassemble antennas while the jammer is powered on and working.
2.Select installation positions with few large metal barriers or building walls between the host and the shielding target area to prevent signal attenuation and shielding blind spots.
3.For outdoor permanent installation, complete independent lightning grounding protection for the host cabinet and supporting antennas, and keep the equipment away from open flames, long-term soaking moisture, high-pressure environments, high-temperature heat sources and strong magnetic field interference sources.
4.If the local mains voltage fluctuates frequently and unstably, a matched voltage stabilizer must be equipped to protect the internal power supply and RF modules from voltage impact damage.
5.When the equipment triggers fault alarms or abnormal jamming effects appear during operation, users must stop operation and contact the official SZ Vodasafe technical service team for inspection and maintenance. Unauthorized disassembly, self-repair or modification of internal modules will invalidate the whole machine warranty, and all losses caused by artificial damage shall be borne by the user.
