Symptoms
- Video is sharp during the day but grainy, blocky, or washed out at night
- Detections degrade after dark
Cause
Night scenes are harder: infra-red lighting, reflections, and higher compression all reduce image quality, which in turn reduces detection reliability.
Resolution
- Clean the camera dome or lens — IR reflects off dust and smears badly.
- Remove or angle away reflective surfaces close to the camera.
- Check that nearby lighting has not changed (a new lamp or a failed one both matter).
- If the image is blocky rather than grainy, raise the bitrate cap for the night profile.
Verification
The night image is usable for a full evening and detections return to normal.
Escalate if
Quality stays poor after cleaning and lighting checks — the camera may need repositioning or a setting change from seeo support.
