Does the State of New Jersey require sex offender registration after I spend more than a few days as a visitor?

I aimed to visit New Jersey state while looking into what restrictions existed for sex offense suspects. The system requires me to inform officials when leaving the state of Florida during my vacation period yet I need to know what limited stay duration exists without needing to immediately register or if I must register immediately after arrival. I had arranged to stay within the state of New Jersey during seven to eight consecutive days.
