RF intelligence
Built for the field

The Sigilite GRID Series is a modular line of passive RF collection systems. We capture persistent wireless identifiers — TPMS, Bluetooth, and Wi-Fi — that travel with vehicles and devices across jurisdictions, deployments, and time. Designed, engineered, and supported in-house by Sigilite for law enforcement.

RF Collection

The signal that travels
with the device.

Modern vehicles and devices broadcast continuously. TPMS sensors transmit identifiers tied to tire pressure monitors. Bluetooth signatures emit from on-board electronics, accessories, and personal devices. Wi-Fi probes broadcast from anything connecting to networks. These signals are persistent. They travel with the device, not with the plate or the operator.

Capturing them gives investigators a layer of selectors that survives plate changes, vehicle handoffs, and jurisdictional boundaries. Pair RF with LPR, video, and records data and the picture becomes durable — a vehicle changing plates is still the same vehicle to a TPMS identifier on the same drive.

Persistent Signal Collection

Capture wireless identifiers and RF activity at scale, in environments where traditional surveillance leaves coverage gaps.

Flexible Field Deployment

Across fixed sites, vehicles, mobile operations, and rapid-response investigative environments. One platform, four mounting configurations.

Cross-Platform Correlation

Align RF activity with LPR, video, CAD, RMS, and investigative platforms — surfacing connected intelligence in the systems agencies already run.

Operational Signal Awareness

Surface real-time awareness and accelerate lead development through RF intelligence integrated into the investigative workflow.

The GRID Series

Four kits.
One collection platform.

Every GRID kit captures TPMS, Bluetooth, and Wi-Fi. They differ in signal capacity (one SDR or two), antenna configuration, and mounting (standard, vehicle, trailer). Pick the kit that fits the deployment — they integrate identically into the broader Sigilite workflow.

Relay

VH-RF-COR
Standard collection

Standard passive RF collection for fixed-site signal awareness. One TPMS SDR with omni or directional antenna. The base unit for corridor and perimeter deployments.

Dual-band directional Yagi for 315 MHz and 433 MHz TPMS signal collection. Focused coverage for targeted monitoring.

STL-ANT-OMNI

Omni Antenna
Fixed Mount

360-degree TPMS collection with weather-resistant construction. Engineered for pole-mounted outdoor deployments.

STL-ANT-OMNI-M

Omni Antenna
Magnetic Mount

Heavy-duty magnetic-base omni antenna for vehicle and temporary deployments. Compatible with Sigilite mobile systems.

STL-ANT-PM

Pole Mount Kit

Durable mounting hardware for Sigilite antennas on poles and vertical structures.

How it fits

RF as one layer
of the operational picture.

The GRID Series captures the signal. The data layer makes it useful. RF activity is correlated against LPR plate reads, video, records, and the platforms your agency already runs — surfacing connections that single-source analysis would miss. The capture is consistent. The integration is scoped per engagement.

Typical configurations route GRID data through 4DV Insight for investigative correlation and through 4DV Vantix for the common operating picture. Custom routing into agency-specific CAD, RMS, and investigative systems is available via Sigilite Integration.

Get Started

One corridor. The right kit. 90 days.

A typical first engagement is a focused deployment covering one corridor or operational area, with GRID kits paired alongside existing LPR or camera infrastructure. We'll help you scope the right starting point — and the right kit for it.
