1. Reduce motion sensitivity.<\/p>\n

2. Exclude trees, roads, and moving shadows.<\/p>\n

3. Create detection zones.<\/p>\n

9. Storage Full<\/h3>\n

When storage fills up, new recordings may stop.<\/p>\n

Solution<\/p>\n

1. Enable automatic overwrite.<\/p>\n

2. Upgrade hard drive capacity.<\/p>\n

3. Reduce recording quality if appropriate.<\/p>\n

4. Use motion recording instead of continuous recording.<\/p>\n

10. Camera Offline<\/h3>\n

IP cameras occasionally lose network communication.<\/p>\n

Fix<\/strong><\/p>\n

1. Restart the camera.<\/p>\n

2. Check network switches.<\/p>\n

3. Verify IP address settings.<\/p>\n

4. Update firmware.<\/p>\n
