I mean, what are the odds you got the same serial number on the sticker there as the replica on Amazon?
does it have an IR Illuminator?

Oh yeah, probably fake as efff, the inserts on the lockout screw holes are not brass. Front screws are not epoxied over either.
Ask for a picture of the illuminator without the diffuser on, bet a white led lurks under there.
