User Guide

Welcome

Welcome to the Sentinel Video System V3 — the most feature-complete live streaming solution on the market today for motorsports.

This guide will walk you through everything you need to know to get your system up and running, from hardware installation to advanced streaming configuration.

Hardware

Inventory

Your Sentinel V3 kit includes the following components:

Installation

Sentinel Video Unit Setup

1. Attach the unit to the base plate using M5 screws and hex nuts
2. Connect the DTM-4P connector to a 12V 5A independent circuit
3. Install WiFi antennas to the labeled ports
4. Attach small arms to the baseplate ball connectors
5. Secure saddle mounts to your chosen roll-bar location

Antenna Placement

The system uses 5G antennas mounted on metal plates to provide ground plane stability. Optimal locations offer clear "sky visibility."

Material Considerations

• Radio-transparent: Glass, fiberglass, and Lexan allow signal to pass through
• Signal loss: Carbon fiber and metal block or degrade signal

Extension Wire Color Codes

• RED — LMH (Low/Mid/High frequency)
• BLACK — MH (Mid/High frequency)
• BLUE — GNSS (GPS)

Camera Setup

Your three Global Shutter cameras provide incredible picture quality and fidelity even in high vibration environments.

• Standard ¼"x20 tripod mounts accommodate various orientations
• USB-C connectors feature locking thumb screws
• Use protective cable covers when not in use
• Image flipping is available via software configuration

CAN Bus Wiring

The system includes standard AIM CAN decode supporting the following data channels:

• Oil pressure
• Oil temperature
• Water temperature
• Fuel level
• Throttle position
• Brake position
• RPM

Connection Wiring

Use the DTM connector with the following wire colors:

SD Card Recording

The SD card records higher-quality footage independent of the broadcast stream.

Requirements

• High-endurance SD card with V30+ speed rating
• Must maintain 25% free space (auto-deletion below threshold)

Recording Specifications

• Format: H.265 in MPEG-TS container
• Composited stream: 10Mb/s
• Individual cameras: 5Mb/s each
• Supports both composited and individual camera recording

Data Service

Sentinel V3 operates on 5G cellular networks. Your kit includes four inactive SIM cards:

• US Mobile cards (3x) — Flexible carrier selection via data pools
• Verizon card (1x) — For existing plan holders

US Mobile Network Options

• Lightspeed — T-Mobile backbone
• Darkstar — AT&T backbone

SIM Installation

Insert full-size SIM cards only, with contacts facing down. Push until you hear a click.

Getting Started
