Sun glare is particularly challenging for surveillance cameras. Even top cameras struggle with such conditions.
One technique suggested is using polarizing filters. Simply put, these filters pass certain polarizations of light, while blocking others, reducing sun glare at specific angles.
To test how polarizers worked in real world scenarios, we tested 720p cameras in three configurations:
- Auto-iris lens with polarizing filter
- Auto-iris lens, no filter
- P-iris lens, no filter
We tested these three cameras outdoors on a bright, sunny day, to see how the polarizing filter impacts performance.
