Camera Image Settings

Getting the correct image settings takes some trial and error because no two scenes are alike. If your goal is to capture plates 24/7 you’ll have to make some trade-offs. Settings that work best at night aren’t necessarily going to work best during the day and vice versa. Most modern IP cameras provide good image quality using the default/automatic settings. However, here are some suggestions you can try to improve accuracy in varying lighting conditions.

These are starting recommendations — adjust based on your scene, distance to the plate, and camera capabilities. Use the pixels-on-target calculation to determine maximum camera distance, and consider Detection Zones to reduce processing load.

Resolution / Frame Rate

  • Recommended: 720p (1280x720) at 20 frames per second (adjust based on camera distance to the plate).

  • Note: Increasing resolution increases CPU processing unless you limit analysis with Detection Zones.

Compression

  • Recommended value: 20

  • Note: Lower compression values yield better image quality at the cost of more bandwidth.

Smart Codecs

  • Recommended: Off

  • If the camera manufacturer compresses using region-of-interest or motion-based techniques, disable that behavior.

Camera Capture Mode

  • (No specific setting provided — configure according to your camera model and scene.)

Wide Dynamic Range

  • Wide Dynamic Range: Off

  • Reason: This feature can add noise, adversely affecting low-light accuracy.

Image Appearance

  • Color level: Default

  • Brightness: Default

  • Sharpness: 60%–65%

  • Contrast: 60–75%

White Balance

  • White balance: Automatic

  • White balance window: Automatic

Wide Dynamic Range (additional)

  • Enable Dynamic Contrast: Off

Exposure Settings

  • Exposure value: 70%

  • Exposure control: Automatic

  • Maximum Exposure Time: 1/1000 second

  • Backlight compensation: Off

  • Exposure zone: Auto

  • Shutter Speed:

    • Fixed @ 1/2000 for slow-speed scenes

    • 1/4000+ for highway-speed scenes

  • Gain: Auto

  • Max Gain:

    • Day: +12 dB

    • Night: +24 dB

  • Note: Avoid excessive gain — it adds noise.

Image Settings

  • Enable automatic iris adjustment: Yes

Day/Night

  • IR cut filter:

    • On during Day

    • Off at Night

IR Illumination (if required)

  • Enable IR illumination: Yes
