Troubleshoot Indigo LPR camera image overexposure. Diagnose lighting, cabling, and software issues for License Plate Recognition systems in commercial kiosks.
Check the network configuration or DHCP server logs.
Use a multimeter to measure the DC voltage output.
Access the camera's web interface and navigate to the system information section.
LPR cameras utilize image sensors (CMOS or CCD) that convert light intensity into electrical signals. Excessive light intensity causes sensor saturation, resulting in a washed-out image. This can stem from automatic gain control (AGC) malfunction, faulty iris control (if present), or incorrect exposure settings. Potential problems exist in the power supply voltage (causing incorrect sensor operation), or signal attenuation due to cabling issues reducing contrast.
LPR camera consistently produces an image that is too bright, particularly during daylight hours. License plate recognition performance is degraded due to image saturation.
Ensure the camera is disconnected from the power source before performing any maintenance or inspection procedures. Avoid using excessive force when cleaning the lens or handling cables. Be mindful of sharp edges or other potential hazards when working around the kiosk. Safe Handling procedures should be observed.
Regularly clean the camera lens with a non-abrasive cloth. Inspect and secure all cable connections to prevent loosening due to vibration or environmental factors. Monitor the camera's performance during different times of the day and adjust settings as needed to maintain optimal image quality. Ensure adequate ventilation to prevent overheating, especially in enclosed kiosks.
If the camera's configuration interface is inaccessible, attempt to locate a physical reset button on the camera body. Pressing and holding this button for a specified duration (refer to the manufacturer's documentation) can often restore the camera to its factory default settings. A ferrite choke on the power cable may reduce noise.
