Smart Camera Night Vision Not Working
4.5
The camera image is pitch black at night despite having IR LEDs.
Symptoms
- Black image at night
- No red glow from IR LEDs
- Grainy video
Possible Causes
- IR cut filter stuck
- Reflections from glass
- Insufficient power
Step-by-Step Fix
1
Check for Obstructions
Ensure no objects are reflecting the IR light back into the lens.
2
Listen for "Click"
The IR filter should click when switching to night mode. If not, it's stuck.
3
External IR Illuminator
If the built-in LEDs are weak, add an external IR floodlight.
When to See a Technician
Placing a camera behind a window will always cause IR glare at night.
