Tech Backpack

Infrastructure Resource Kit for Safety AI Support Technicians

Welcome to the Tech Backpack, your go-to reference for the foundational infrastructure knowledge needed to support Safety AI systems in the field. This page is designed to give you a clear overview of the essential networking, operating system, and system-level concepts that form the backbone of our Safety AI products. Think of it as the toolkit you carry in your mind — ready to reference whenever you encounter technical challenges on site.

Inside this Tech Backpack, you will find concise explanations, practical tips, and best practices for managing and troubleshooting the underlying infrastructure. Whether you are connecting cameras, inspecting network configurations, or navigating Linux environments, this guide will help you understand how the system operates and how to maintain its reliability, even before diving into the Safety AI software itself.

What's inside the backpack?

This Tech Backpack is organized into key areas that cover the infrastructure knowledge you’ll need in the field. Each section focuses on practical skills and concepts that directly support the operation, maintenance, and troubleshooting of Safety AI systems. From understanding how devices communicate over a network to navigating Linux environments and verifying hardware connections, the guide ensures you have the essentials at your fingertips.

While the outline may look broad, it is designed to be modular — you can quickly reference the section relevant to the task at hand. Whether you are diagnosing a camera feed, checking system performance, or managing software updates, the Tech Backpack equips you with the foundational knowledge to act efficiently and confidently.

Networking Fundamentals

Prerequisite Knowledge

Before diving into networking for Safety AI systems, technicians should be comfortable with:

• Basic computer concepts (what an IP address is, how devices connect to each other)
• Familiarity with operating system navigation (Windows/Linux basics)
• Understanding of wired connections (Ethernet cables, ports)
• Comfort using command-line tools (terminal/CLI)

Checklist

To support Safety AI deployments, technicians need to know how to do the following:

• Verify device IPs and connectivity
• Check network cables and ports
• Set and check IP configuration
• Check internet access
• Check VPN connectivity

Networking

Overview of Safety AI networks

In Safety AI setups, a network is simply how the devices are connected so the system can function.

In practice, this means:

• Cameras send video over the network to the AI device (e.g. Jetson).
• The AI device sends alerts and status over the same network to an IPIO.
• Your laptop uses the network to access, configure, or troubleshoot the system.

For a support technician, the network is:

• The Ethernet cable between devices
• The switch they are plugged into
• The IP addresses that let them “find” each other

If the network is down, the AI might still run — but it won’t see cameras, send alarms, or be reachable for support.

Devices in the network

In a typical Safety AI network, you can expect to see:

• VISBOX, the AI processing unit (e.g. Jetson / on-edge computer)
• Cameras (IP cameras or networked vision sensors)
• Network switch (often PoE and/or industrial)
• IPIO, to connect to external parties over dry contact
• Support laptop (yours, for setup and troubleshooting)
• Remote access gateway / VPN device, probably a Teltonika TRB-140 or RUT200
• Wifi Access Point (AP)

Optional / site-dependent:

• A monitoring PC connected to a display
• PLC / control system (if integrated)
• NVR or video recorder

Physical Layer

Physical layer is the actual hardware and cabling that makes the network work. Most field issues originate here, so this is always the first place to check.

You will typically see:

• Ethernet cables (Cat5e / Cat6)
• Industrial network switch
• Camera network ports
• AI device (Jetson) Ethernet port
• Router / firewall (if present)

First on-site checks:

• Are all cables firmly plugged in?
• Are link lights on at both ends?
• Are there any crushed, bent, or damaged cables?
• Is the network switch powered on?

If this layer fails, nothing above it will work. Make sure you know how to terminate and check a patch cable. Always make sure cables are working when troubleshooting field problems.
