Summary
The Proxicam Pedestrian Detection System utilizes a highly modular, plug-and-play hardware architecture designed to satisfy different types of machines, operational preferences, and budgets. By standardizing connections and processing intelligence directly at the edge, the system allows safety managers to seamlessly scale their setup—from a single standalone proximity sensor to a comprehensive multi-camera layout with cloud-connected data logging—while minimizing unnecessary componentry and complex wiring.
Key System Components
-
Proxicam AI Camera (PXCAM-EVO):
The core edge-computing sensor embedded with artificial intelligence to detect pedestrians and other objects.. -
Human Machine Interfaces (HMI):
Choose between the comprehensive Proxicam LCD Monitor (PXLCD) for full 360-degree video visibility, or the compact Detection Indicator (PXLED) for localized visual/audible alerts. -
Data and Video Logger (DV-HUB):
An optional secure, ruggedised hub that captures continuous multi-channel video and logs critical proximity events and asset telemetry. -
Enhancement Box (PXE):
An advanced in-line I/O controller required to unlock dynamic safety features like Safe-to-Approach and Dynamic Detection. -
Voltage Converter & I/O Controller (PXVC):
A mandatory power regulation and switching relay strictly required for standalone and PXLED setups. -
Pedestrian Voice Alert (PXALERT):
An external outward-facing flasher and spoken warning module.
System Interconnectivity and Dependencies
The Proxicam ecosystem is designed to be highly interoperable, utilizing standard 8-core, 5mm OD cables with 8-PIN DIN GX12 screw-lock connectors and waterproof O-ring seals. When planning your installation, follow these sequential steps to ensure all critical hardware dependencies are met:
-
Determine the Core HMI and Power Architecture:
Identify whether the machine will utilize the Proxicam LCD Monitor, the DV-Hub, or operate as a standalone/PXLED setup. This dictates your power routing. -
Integrate the Voltage Converter (Dependency Check):
- If using a PXLED or Standalone setup: You MUST install the Proxicam Voltage Converter (PXVC) in-line with the camera circuit. The PXVC acts as the step-down regulator (accepting up to 48V DC) and houses the internal relay responsible for managing the conditional input and output trigger signals. The alert devices will not function without it.
- If using a PXLCD or DV-Hub setup: You MUST NOT install the PXVC. The LCD Monitor and DV-Hub manage their own internal power regulation and I/O switching. Installing a PXVC in these configurations will cause the system to fail.
-
Incorporate Advanced Logic Controllers (Optional):
If your site requires Dynamic Detection (muting based on vehicle direction) or Safe-to-Approach (muting when parked), connect the Proxicam Enhancement Box (PXE) in-line between the camera input harness and the LCD Monitor. -
Route Camera Extension Harnesses:
Connect the PXCAM-EVO cameras to the central hubs (LCD, DV-Hub, or PXVC) using the appropriate 1m, 3m, or 5m extension harnesses. Ensure all cables are routed safely away from mechanical pinch points and high heat. -
Connect Third-Party Output Triggers (Optional):
Route the Alarm-Out wire or the PXE accessory outputs to external devices like sirens, beacons, or the PXALERT voice module to provide active pedestrian warnings. -
Perform Temporary Network Calibration:
To configure the AI detection zones, temporarily plug the USBCAL WiFi dongle in-line between the camera and the extension harness. This creates a local network to access the Configuration App. **WARNING:** The USBCAL dongle is not weatherproof and must be removed from the circuit before the machine returns to active service.
Troubleshooting & FAQ
I am installing a Proxicam LCD Monitor (PXLCD), do I need to wire the PXVC Voltage Converter into the circuit?
No. The Proxicam Voltage Converter (PXVC) is strictly dependent on standalone or PXLED installations. The PXLCD monitor and DV-Hub components feature their own integrated power regulation. Connecting a PXVC to an LCD or DV-Hub setup will disrupt power flow and void standard operational parameters.
My standalone system with a third-party beacon is completely unresponsive when a pedestrian walks into the zone.
First, ensure that the mandatory PXVC is physically installed in the circuit. If the PXVC is present, verify that the Alarm-In conditional trigger wire is actively receiving positive voltage (12V-48V DC). Without voltage applied to the Alarm-In wire, the internal relay will not close, and the system will not issue an output trigger.
