DV-HUB Data & Video Logger


Summary

The Proxicam DV-HUB (SKU: DV-HUB) is a ruggedised, edge-computing data and video logger designed to capture high-definition event video and machine telemetry. Operating as the central recording and transmission node for the Proxicam Pedestrian Detection System, it integrates local solid-state storage with wireless connectivity for seamless incident reporting and cloud-based analytics via the FleetHQ platform (optional).

System Features and Functions

Hardware and Environmental Durability

Engineered for demanding industrial environments, the DV-HUB features a tamper-proof, die-cast aluminum casing that can be securely bolted to any flat surface.

  • Ingress Protection: 
    IP69K rated for complete protection against water and dust ingress.
  • Vibration Resistance: 
    Meets MIL-STD-810G military specifications for extreme anti-vibration performance.
  • Data Security: 
    Features a lockable storage bay (supplied with two keys) to prevent unauthorized physical access to the SD Card and the SSD drive. Synchronising with the cloud using industry-standard TLS authentication protocols for secure data transfer. 

 

Data Storage and Video Recording

The DV-HUB utilizes a removable 2.5” Solid State Drive (SSD) supporting up to 2TB of storage capacity. The system handles two recording protocols using a First-In, First-Out (FIFO) looping overwrite mechanism.

1. Event-Based Recording 

When a pedestrian breaches a predefined detection zone, the DV-HUB logs a critical event.

  • Captures a 10-second high-definition (720p, H264) video clip following the detection event, aggregating feeds from all connected camera channels.
  • Logs machine telemetry data including a timestamp (UTC/GMT+0), GPS location, Asset ID and speed.
  • Event video files average 2.5Mb per 10 seconds per camera.
  • When online; pushes event data and videos to the Proxicam Cloud Server (FleetHQ) via WiFi or 4G LTE.
  • When offline; stores the event videos and data locally on the SSD drive and uploads when connection becomes available.

2. Continuous Recording

  • Records HD (720p, H264) video constantly from all connected Proxicam Cameras in 5-minute segments.
  • Utilizes H.264 video compression.
  • Files average 64.5Mb per 5-minute interval per camera.
  • Note: Continuous recordings do not include telemetry data and are not uploaded to the cloud. They must be retrieved using the DV-Player App by removing the SSD and connecting it to a PC using a SATA-to-USB adapter.

 

Wireless Connectivity

To enable automatic cloud upload of event videos and data, as well as over-the-air (OTA) updates, the DV-HUB requires network configuration.

  • Networks Supported: Cellular 4G LTE networks and 2.4GHz WiFi networks.
  • Antenna Placement: Connect the supplied puck-style antenna to the rear of the DV-HUB. Ensure the antenna is mounted with a clear view of the sky and is not obstructed by metal panels.

 

Trigger Inputs & Outputs

The DV-HUB harness facilitates interaction with third-party hardware and machine states.

  • AUX/REV Input (10-32V): Applying a positive voltage switches the Rear camera feed into full-screen mode on the connected LCD monitor. This is required for the Safe-to-Approach feature to function correctly.
  • FWD/MUTE-IN (10-32V): Applying a positive voltage switches the Front camera feed into full-screen mode on the connected LCD monitor. This is required for the Safe-to-Approach feature to function correctly.
  • Trigger Output 1 Wire: Activated when a pedestrian detection event occurs, regardless of Safe-to-Approach states (except when system is muted). Utilise for general alerting regardless of direction of travel (MODE 1 & 2) or only on detections in direction of travel (MODE 3 & 4). Delivers a 12V+ (500mA) positive trigger output to activate external devices (e.g., beacons or sirens).
  • Trigger Output 2 Wire: Activated when a pedestrian detection event occurs according to the Safe-to-Approach configuration and the machines direction of travel (except when system is muted). Utilise this output for triggering shut-off and slow-down of systems. Delivers a 12V+ (500mA) positive trigger output to activate external devices (e.g., beacons or sirens).

Configuration and Setup

The initial setup and configuration of the DV-HUB is performed using the DV-HUB Configuration App (DV-Config App) which can be found on the SD Card installed behind the sealed door of the DV-Hub.

For configuration and setup of the DV-HUB, please see DV-Hub Configuration App.

Troubleshooting & FAQ

The SSD is empty, and there are no files or folders. Why? 

This indicates that the DV-Hub was not initially set up using the DV-HUB Configuration App (DV-Config App).

With the Proxicam system powered off, remove the SD Card from behind the door of the DV-HUB, then follow the instructions in the article DV-Hub Configuration App.

 

The DV-Player application shows no videos on the SSD. 

Confirm you are accessing the correct drive first by ensuring the drive you are accessing is not the C:/ drive. Confirm the drive in question has a capacity of 1-2 Tb of storage as this is the capacity the DV-HUB supports. Confirm the drive has a filesystem format of FAT32. If the drive is formatted as NTFS or exFAT, then this indicates that the SSD was not formatted to the correct filesystem. Please remove the SD Card and run the DV-Config Configuration App (article DV-Hub Configuration App).

The DV-Player_v2.1.exe file must be located in the base directory of the SSD drive to work correctly. Ensure the DV-Player executable is located in the base directory of the SSD drive before opening the app.

There should be several folders located in the base directory of the SSD drive such as flags, logs and record. If there are no folders in the base directory then this indicates that the SSD was not formatted to the correct filesystem. Please remove the SD Card and run the DV-Config Configuration App (article DV-Hub Configuration App).

Check inside the /record/normal/ folder; each folder in this directory is named with a date (YYYYMMDD), then the subfolders are the hour of the day, and then the next folder level down are the minutes of the hour. The video files are located within the minutes-level folder and should be playable using a standard media player (Such as VLC Media Player)

If video files exist on the SSD drive but the application was not able to find them or play them, delete the .DV-Player folder from the root directory of the drive and relaunch the DV-Player_v2.1.exe application to force a fresh scan for video files on the drive.

 

Why doesn't the Detection Indicator (PXLED) issue a "System-Ready" double beep on startup? 

When the Proxicam cameras are wired in conjunction with the DV-HUB, the standard PXLED startup sequence is suppressed.

This is normal operational behavior; verify the DV-HUB LEDs are alternating Red and Green to confirm the system is active.
