Nitro
USP SecNET card access and YTMS Pro time attendance
Nitro Solution (nitrosec.com) builds card door-access controllers and time-attendance software for sites that want stable Wiegand hardware rather than face terminals. Swan CCTV supplies and installs USP SecNET with the NAC8000N network controller, YTMS Pro attendance reports, NAC3000B standalone doors and NR-series readers. Hong Kong catalogues also list NAC3550N (paired with the NAC8000N) and the NAC3001B-EM control module — we confirm those two against the current datasheet before quoting capacity.
