High-end security cameras have day/night modes with IR cutoff filters. But yes, you're overly paranoid.

Why do they have that filter?

Cellphones don’t and take good pictures in day or night conditions.

Because you cannot have high-quality image, especially with good spectral content, both day and night, without an IR cutoff filter. Some cellphones do have IR filters, others can't take decent low-light photos. And many "secured areas" would actually have IR lights on to facilitate, well - visual surveillance.
