If I can't use IR, what other option do I have?
The easy way is to leave the lights on, but this raises some concerns regarding electric bills.
My issue here is that at night the cameras instead of producing a uniform (steady) dark image, they produce a blurry dark image full of "moving" noise, this causes the software to identify this as movement and spends all night recording useless images.
If you have any suggestions I'd appreciate them very much.
