Hanwha NHP-P200 2-Door IP Access Controller
The NHP-P200 is a compact, field-deployable access control controller designed for security integrators working in environments where network dependency must be eliminated or minimized. Built on Hanwha's OnCAFE platform, this controller handles two doors natively and scales to four OSDP readers per port, allowing you to cover multi-door installations without external reader panels. The NHP-P200 runs entirely on PoE++ (802.3bt Type 3 Class 6), meaning a single Ethernet cable delivers both data and power—no separate 24VDC supply needed at the access point.
Key Features
- Dual Wiegand/OSDP Reader Ports with 4-Reader Scalability: Each of the two native ports supports Wiegand readers or OSDP (Open Supervised Device Protocol). If you need to manage more than two doors, you can cascade up to four OSDP readers per port. OSDP is critical here—unlike Wiegand, which only sends card data, OSDP reports the physical state of the reader to the controller. If a reader is tampered with, disconnected, or powered down, the NHP-P200 alerts you immediately. In warehouse or manufacturing environments where unauthorized reader bypass is a concern, this supervised feedback prevents silent security gaps.
- 250,000-Event Offline Cache with 50,000-Cardholder Database: The NHP-P200 stores a quarter-million access events locally and maintains a cached credential database of up to 50,000 cardholders. When your network connection fails—whether due to switch failure, fiber cut, or ISP outage—the controller continues to evaluate credentials against its local ruleset and grants or denies access without waiting for a management server. Once connectivity returns, the controller syncs all offline events back to your central management platform. This is a core requirement for any installation where a network outage cannot halt access operations: warehouses with continuous 24/7 operations, manufacturing facilities running multiple shifts, or remote offices where IT support is limited.
- 5 Supervised Inputs + 4 OSDP Flex Inputs: Supervised inputs are hardwired connections that report their status continuously. If the wire is cut or the connection fails, the system alerts you—this prevents a silent bypass where someone cuts a sensor wire and the controller never knows. The four OSDP Flex inputs add additional request channels for sensors, push-to-exit buttons, or other access triggers, all reporting state through the same supervised protocol.
- 2 Form-C Relay Outputs per Door: Each relay output can be independently configured as a dry contact, 12VDC, or 24VDC output. This flexibility means you can drive electric strikes, magnetic locks, or audible alarms without intermediate converters. The controller routes power and switching logic on a per-door basis, so each door's access rules and relay behavior are independent.
- PoE++ (802.3bt Type 3) Single-Cable Power Delivery: The NHP-P200 draws all its power from one RJ-45 Ethernet connection using the 802.3bt Type 3 standard (Class 6). This eliminates the need for a separate 24VDC supply at the door or reader location. If redundancy is critical, optional 12VDC or 24VDC hardwired fallback can be added for offline operation during extended network loss, but the primary design assumes network-powered deployment.
- FIPS 140-3 Level 3 Cryptography with Hardware TPM: End-to-end encryption uses TLS 1.3 and AES-256. All cryptographic operations run on an on-board TPM (Trusted Platform Module), meaning sensitive keys never exist in unencrypted software memory. This hardware-based approach meets FIPS 140-3 Level 3 certification, a requirement for access systems in financial institutions, healthcare facilities, and government buildings where compliance audits demand provable key management and encryption integrity.
- Real-Time Tamper Monitoring & Power Event Logging: Supervised inputs trigger immediate tamper alerts if physical attacks are detected (wire cut, enclosure opened, connection failure). The controller also logs every power loss and restoration event, creating an audit trail of when the system lost redundancy. In critical access scenarios, this log proves the system was operationally sound or identifies periods of vulnerability.
- Compact Aluminum Enclosure, Wide Temperature Range: The NHP-P200 measures 7.24" × 7.24" × 1.67" and mounts in standard electrical boxes or on a wall next to the door. The aluminum construction provides EMI shielding in noisy industrial environments. Operating temperature range spans -20°C to +60°C (-4°F to +140°F), so the controller handles cold, unheated warehouses, outdoor gate installations, and hot server rooms without thermal shutdown or condensation issues.
Integration & Compatibility
The NHP-P200 integrates natively with OnCAFE-based access management systems. It supports ONVIF interoperability for third-party video management and access control platforms, enabling you to tie door events into network video recorder timelines and video analytics workflows. This connection matters in retail loss-prevention, corporate security, and multi-site operations where correlated video and access logs are essential for incident investigation.
When selecting an access control controller, evaluate three factors: (1) the number of doors and readers you need to support, (2) your tolerance for network downtime, and (3) your compliance and audit requirements. If you have only one door and network availability is guaranteed, a simpler single-door controller may suffice. If you require two to four doors, offline operation, and FIPS-level encryption, the NHP-P200 is purpose-built for that scenario. Consult a detailed access control integration guide if you need help mapping reader protocols, relay wiring, and supervised input logic to your facility layout.
Frequently Asked Questions
Q: Does the NHP-P200 require constant network connectivity to grant or deny access?
A: No. The NHP-P200 caches up to 50,000 cardholders and 250,000 access events locally. When your network is offline, the controller evaluates credentials against its cached database and makes access decisions based on local rules. Once the network is restored, offline events sync back to your management server.
Q: Can I use Wiegand readers with the NHP-P200?
A: Yes. The dual reader ports support both Wiegand and OSDP protocols. However, OSDP is strongly recommended because it reports reader state (tamper, disconnection, power loss) back to the controller, whereas Wiegand only sends card data.
Q: What happens if the Ethernet cable is cut or the switch loses power?
A: The NHP-P200 continues to operate from its internal PoE++ stored power reserve and offline credential cache. It grants or denies access based on local rules. A hardwired 12VDC or 24VDC fallback supply can be added for extended offline operation if your site requires it.
Q: Is the NHP-P200 suitable for outdoor installations?
A: The controller itself is rated for -20°C to +60°C operation, but the compact aluminum enclosure (7.24" × 7.24" × 1.67") is designed for wall or electrical box mounting indoors or in sheltered locations. Readers and sensors connected to it can be outdoor-rated (IP66/IP67), but the controller should be mounted in a protected area.
Q: Does the NHP-P200 meet FIPS 140-3 requirements?
A: Yes. The NHP-P200 carries FIPS 140-3 Level 3 certification with an on-board TPM (Trusted Platform Module). All credential encryption uses TLS 1.3 and AES-256, meeting compliance requirements for government, healthcare, and financial institution deployments.
Q: Can I expand the NHP-P200 to handle more than two doors?
A: Yes, by scaling OSDP readers. Each of the two native ports can support up to four OSDP readers, allowing you to manage up to eight door readers from a single controller. However, the controller itself is rated for two doors natively; adding readers increases reader count, not door count.

The NHP-P200 (often searched as NHP P200) is a rare breed: a two-door controller that actually handles network-unavailable scenarios without losing access intelligence. The 250,000-event offline cache and 50,000-cardholder database are not marketing numbers—they directly address the #1 complaint from warehouse and manufacturing operations: a network outage that brings access control to a standstill. The FIPS 140-3 Level 3 certification with on-board TPM is equally concrete—if your facility audit requires cryptographic hardware validation, this controller proves it in the datasheet, not in a compliance statement.
Technical Highlights:
- Offline Event Storage (250,000 events): A typical mid-size facility logs 100–200 access events per day per door. At two doors, that's 200–400 daily events. The NHP-P200 stores 250,000 events—enough for roughly 16 months of 24/7 operation on a single door, or 8 months across both doors. Real benefit: if your network fails for a week, you don't lose access history. Offline events sync automatically when connectivity returns.
- PoE++ (802.3bt) Single-Cable Power: The NHP-P200 draws 802.3bt Type 3 power, which means a modern PoE++ switch delivers both network and 12.95W of power through one RJ-45 cable. Compare this to controllers requiring a separate 24VDC PSU at the door: you eliminate a second power run, reduce installation cost, and simplify troubleshooting. Optional 12/24VDC fallback can be hardwired for redundancy without making it mandatory.
- OSDP Reader Scaling (4 readers per port): OSDP reports reader state—tamper, disconnection, power loss—back to the controller in real time. If a reader is ripped off the wall, you know immediately. If Wiegand-only readers are your installed base, the NHP-P200 accepts both protocols on the same port. But if you're specifying readers from scratch, OSDP eliminates the blind spot that Wiegand creates.
Deployment Considerations:
- The NHP-P200 is a two-door native controller. If you need four or more independent doors, you'll need two controllers. Verify your door count and reader layout before committing.
- Supervised inputs are hardwired—plan your sensor runs carefully. If you have 15 doors and 50+ sensors across a large facility, the NHP-P200 becomes a single-point dependency; consider distributed controllers instead.
- The -20°C to +60°C operating range is robust for warehouse and outdoor gate installations, but don't mount the aluminum enclosure itself in direct UV or salt-spray environments without a weatherproof cabinet.
Deploy the NHP-P200 when you have a two-to-four-door cluster in a high-availability environment—warehouse access points, manufacturing floor entrances, or remote office sites where network outages happen regularly and access cannot stop. Pair it with OSDP readers for full supervision and you eliminate guesswork about reader integrity.
