IR camera work through perplex?

[stuffed 0]

Need to place an IR NPR camera down near number plate height and build a small vandal proof enclosure. Would this still work ok if we had a strong clear perplex type window for it to sit behind?!

Thanks

I assume you mean Perspex?

 

Probably not - chances are 99.9999% that you'll see "IR fogging" from the LEDs reflecting off the inside of the pane. Use a non-IR camera or disable the onboard IR, and use an IR illuminator outside the enclosure.
