Nitro NR-CRD — Specs & Hong Kong Installation
NR-series smart card reader for Nitro NAC doors.
Best for: Entry readers on SecNET doors
Product overview
The NR-CRD is Nitro’s NR-series smart card reader, listed alongside the NAC controllers by Hong Kong distributors.
It is the reader head for a NAC8000N or other Nitro controller. Enrolment and door rules stay in USP SecNET or on the standalone panel, not in the reader.

Key features
- Matches the Nitro controller range
- Reader only — cards and time zones live on SecNET or the standalone panel
- Works with the NAC8000N auto Wiegand input
- Professional supply and installation by Swan CCTV in Hong Kong
- Configured and tested on-site (not leave-in-box DIY)
- Documentation and user training included with installation packages
Compatibility
- NAC8000N Wiegand reader inputs (26/32/34/64/66-bit auto-detect on that panel).
- NAC3000B standalone controllers when the door uses a separate reader.
