2N 01975-001 IP/LTE Verso Security Bundle Intercom
The 2N 01975-001 is a purpose-built intercom security bundle designed to harden entrance control on commercial, institutional, and multi-tenant properties. Unlike standalone intercom units, this bundle packages three critical security layers—tamper detection, I/O expansion, and relay-based lock protection—into a single coordinated system. This approach eliminates the need to source and integrate components separately, reducing installation complexity while ensuring consistent security logic across entry points.
Key Features
- Tamper Switch Detection: Senses physical interference with the intercom housing itself. When triggered, the unit alerts your access control system or VMS immediately—critical for catching attempted bypass attacks before they escalate. This is distinct from door-state monitoring; it protects the device itself.
- I/O Module Expansion: Adds configurable input and output connections that let you wire the intercom into wider security logic—door release triggers, gate controls, additional sensors, or third-party access systems. Eliminates the need for external relay cards in many deployments.
- Security Relay Protection: Defends against relay bypass attacks (attempts to fake or override lock commands). The relay ensures that only authenticated intercom signals can trigger door release, not random voltage spikes or tampering at the wiring level.
- Modular Architecture: All three components (tamper switch, I/O module, relay) can be ordered and deployed independently if your deployment requires partial capability. Useful for phased upgrades or cost-constrained rollouts where not every entrance needs all three protections immediately.
- IP and LTE Ready: Designed to work with both hardwired IP network infrastructure and cellular LTE backup connectivity, making it suitable for remote or unstable network environments where IP alone may drop.
- Enterprise Integration: The bundle integrates with industry-standard access control systems, IP surveillance platforms, and network management architectures. If your facility runs Milestone, Genetec, or proprietary ONVIF-based VMS, this unit communicates via standard protocols.
Integration and Compatibility
The 01975-001 works alongside existing 2N IP cameras and intercom lines in the same facility. It connects to centralized access control panels, network video recorders, and IP-based door controllers via standard Ethernet or cellular fallback. Configure the I/O module to trigger locks, gates, buzzers, or alert relays tied to your broader security posture. No proprietary middleware required—standard ONVIF and IP protocols apply.
When to Choose This Bundle vs. Standalone Components
If you need only tamper detection, a basic intercom may suffice. If you need tamper detection and relay-protected lock logic and third-party sensor integration, the bundled approach cuts procurement and integration time by consolidating three discrete products into one. The trade-off: you pay for all three functions upfront, even if one entrance doesn't use all three features. For facilities deploying security across 10+ entry points, this bundle often costs less than buying components separately and reduces cabling and configuration overhead.
Deployment Context
Typical installations include corporate office main lobbies (tamper + relay prevents unauthorized access), medical facilities with restricted wings (I/O ties intercom to badge reader logic), government buildings (tamper relay meets physical security audit requirements), and multi-tenant residential complexes (relay prevents tailgating via intercom bypass). Anywhere you cannot afford a compromised entrance control.
Frequently Asked Questions
Q: Does the 01975-001 require a separate access control panel, or is it standalone?
A: It is not a standalone access control solution. The bundle requires integration with an existing access control system, VMS, or central management platform to handle authentication logic and override decisions. The tamper switch, I/O module, and relay are supporting security layers, not the primary controller.
Q: Can I order just the tamper switch or just the relay without the full bundle?
A: Yes. 2N offers modular ordering—you can purchase components separately. Contact the manufacturer or your integrator for individual part numbers if you need partial deployment.
Q: How does LTE fallback work if my IP network goes down?
A: The bundle is LTE-compatible, meaning it can operate over cellular backup if your facility has a secondary cellular gateway. Configuration and SIM provisioning are handled during system setup by your integrator.
Q: What happens if someone cuts the power to the intercom?
A: The security relay is typically configured in a fail-secure state—if power is lost, the relay de-energizes and the door lock remains locked (or in a default safe state). Verify this configuration with your integrator during commissioning.
Q: Is the 01975-001 compatible with Milestone or Genetec?
A: The bundle integrates via IP network protocols and ONVIF Profile S/T. Milestone and Genetec both support ONVIF-compliant devices; however, full two-way intercom functionality may require additional connector plugins. Confirm with your VMS vendor before deployment.
Q: Can the I/O module trigger multiple outputs (e.g., lock and alarm and buzzer)?
A: Yes. The I/O module supports configurable outputs; you can assign multiple actions to a single intercom call or event. Wiring and logic configuration depend on your relay rack and access control rules.

The 2N 01975-001 bundle is the right choice if your facility has faced or is concerned about relay-bypass attacks or sustained tampering attempts on door intercoms. The three-layer approach—tamper sensing, I/O flexibility, and relay protection—covers both the electronics and the physical enclosure, addressing real attack vectors that a basic intercom ignores.
Technical Highlights:
- Tamper Switch: Detects unauthorized physical interference with the intercom housing before an attacker can reach internal wiring or relay connections. Triggers immediate alerts to your access control system—no silent breaches.
- I/O Module: Configurable inputs and outputs let you tie the intercom to door release logic, gate controls, additional sensors, or alarm panels without requiring external relay racks for simple deployments. Reduces single points of failure in the wiring path.
- Security Relay: Prevents voltage spikes, cutting attacks, or false signals on the wiring from forcing a lock release. Only authenticated intercom commands trigger the relay—critical for preventing tailgating or forced entry at the electrical level.
Deployment Considerations:
- This bundle is a security enhancement layer, not a standalone access control system. You must have a central controller (panel, VMS, or cloud platform) to make the actual allow/deny decisions. The 01975-001 enforces those decisions and detects tampering.
- The fail-secure relay configuration must be verified during commissioning. If power loss should trigger an alarm rather than lock-down, your integrator must reprogram the relay behavior—it doesn't happen by default.
- LTE capability is present but requires a separate cellular gateway and SIM provisioning. IP connectivity alone will work; LTE is a fallback option, not a replacement.
Deploy the 2N 01975-001 at entrances where tampering risk is real—high-security lobbies, restricted-access wings in healthcare or government, or perimeter gates in multi-tenant properties. For standard apartment buildings or low-risk commercial spaces where intercoms rarely face physical attacks, a basic unit may suffice.
