Indigo LPR Camera Object Detection Diagnostic Report -... | terminalfaults.org

Technical Background:

Object detection algorithms rely on consistent image data. Environmental factors, such as temperature fluctuations (-40C), can affect sensor calibration and introduce noise. Signal attenuation due to cable degradation or EMI from nearby equipment (e.g., kiosk displays) can reduce image quality. The algorithms' sensitivity is adjusted via firmware; faulty firmware updates or corruption may contribute. Power supply fluctuations can affect the camera's processing capabilities.

Symptoms:

The LPR camera fails to reliably detect and/or identify objects, specifically experiencing difficulties when traffic cones are present in the field of view.

Possible Causes:

1. Incorrect or corrupted firmware version affecting object detection parameters.
2. Environmental factors (extreme cold) impacting sensor performance and calibration.
3. Signal interference (EMI) from kiosk components or nearby electronic devices.
4. Power supply instability causing erratic camera operation and reduced processing capacity.
5. Lens obstruction or damage due to vandalism, obscuring the camera's view.
6. Degradation of camera cabling leading to signal loss and data corruption.

Solution:

1

Verify the camera's firmware version against the manufacturer's recommended version for object detection accuracy. Update if necessary, following the manufacturer's specified procedure.
2

Inspect the camera lens for any physical obstructions, damage, or condensation. Clean the lens with a suitable lens cleaning solution and a lint-free cloth.
3

Evaluate the camera's power supply voltage for stability. Ensure it falls within the manufacturer's specified voltage range. Use a multimeter for accurate measurement.
4

Examine the camera's cabling for any signs of damage, wear, or loose connections. Replace damaged cables with manufacturer-approved replacements.
5

Analyse the camera's system environment for potential sources of EMI. Shielding or relocating the camera may be necessary.
6

If possible, access the camera's configuration interface (through a secure channel) and adjust object detection parameters (sensitivity, minimum object size) to optimize detection performance.
7

Perform a controlled environment test with various traffic cones to evaluate recognition.

Safety Warning:

Ensure the power supply to the camera is disconnected prior to any inspection or maintenance. Avoid touching any internal components. Use appropriate static discharge precautions when handling any electronic components. This device is PCI-PTS secured. Do not attempt to open the enclosure. Tampering will trigger anti-tamper mechanisms rendering the device inoperable.

Prevention:

Regularly inspect and clean the camera lens. Implement cable strain relief to prevent damage. Periodically check the camera's firmware for updates. Monitor the power supply voltage for stability. Protect the camera from extreme weather conditions (where feasible).

Expert Tip:

Many LPR cameras have an 'events' log. Review the log before a firmware update to check whether you can capture a 'before' and 'after' state, to test the traffic cone recognition. Check the device's settings for a 'factory reset' option (using secure access) as a first-stage resolution.
