Code Blue SLNF0174 4G LTE Cellular Module
Overview
The Code Blue SLNF0174 is a 4G LTE cellular module purpose-built for surveillance deployments where hardwired network infrastructure is unavailable or cost-prohibitive. This is not a camera—it is a standalone cellular gateway designed to bridge your surveillance camera, access control, or alarm panel to the cloud or a central monitoring station via cellular connectivity. The SLNF0174 handles the wireless handoff and power management, letting you install a complete surveillance system at remote job sites, temporary facilities, or locations where trenching or conduit runs are impractical.
Key Features
- 4G LTE Connectivity: Delivers cellular backhaul for surveillance streams, eliminating the need for on-site fiber or cable runs. Real-world throughput depends on signal strength and carrier capacity—budget for 5–15 Mbps sustained for video in congested areas, higher in rural deployments with strong signal.
- IP68 Environmental Rating: Sealed against dust and temporary immersion (up to 1 meter for 30 minutes per IEC 60529). Deploy this module outdoors or in damp electrical enclosures without fear of moisture ingress into the cellular radio or antenna connectors.
- PoE and 12–24V DC Power Options: Accepts both standard 802.3af PoE (up to 13W) and hardwired 12–24V DC supply, giving you flexibility in power sourcing. PoE simplifies single-cable runs to nearby switches; 12–24V DC suits battery-backed or solar deployments at remote sites.
- 120V AC Primary Input: The module can also accept mains power where available, supporting a hybrid power architecture—mains when present, cellular failover when mains drops. This matters on job sites with intermittent power stability.
- Paging Amplifier Support: Works in conjunction with paging systems during production installations, allowing audio alerts to propagate through cellular-connected speaker networks at remote facilities.
- Ruggedized for Field Deployment: Designed for the electrical and environmental stresses of surveillance enclosures, outdoor cabinets, and temporary site installations where equipment sees temperature swings, vibration, and occasional water exposure.
Integration & Compatibility
The SLNF0174 pairs with standard surveillance cameras, IP intercoms, and access control panels that output Ethernet or serial data. It acts as a transparent cellular bridge—your camera streams over LTE to a cloud VMS, a local monitoring center, or a cellular-enabled NVR at the main office. Configuration typically involves SIM provisioning, APN setup, and IP routing at the module—consult your system integrator for carrier-specific firmware and profile tuning.
Because this is a generic cellular module, compatibility with specific VMS platforms (Milestone, Axis Camera Station, etc.) depends on the upstream device and your network architecture, not on the SLNF0174 itself. The module is carrier-agnostic—works with major North American, European, and Asia-Pacific LTE providers.

Frequently Asked Questions
Q: Can the SLNF0174 power a surveillance camera directly, or does it just provide connectivity?
A: The SLNF0174 is a cellular gateway and power interface—it does not act as a standalone PoE injector or power supply for cameras. It provides connectivity and power management for itself and, in some configurations, relay or gateway functionality for other devices. Your camera requires its own power source (PoE from a switch, or hardwired 12V DC). The module's PoE input or 12–24V DC input supplies the SLNF0174 itself and any integrated relays or remote shutdown circuits you wire to it.
Q: What is the typical data throughput on 4G LTE with the SLNF0174?
A: Real-world throughput varies widely—typically 5–15 Mbps downstream on congested networks, up to 25–50 Mbps in areas with strong signal and low congestion. This is sufficient for one to three H.265-encoded camera streams at moderate resolution (720p–1080p). If you need multiple full-resolution 4K streams or high-frame-rate analytics, 4G LTE alone is borderline; you may need carrier aggregation or a backup fixed-line connection.
Q: Is the SLNF0174 NDAA Section 889 compliant?
A: Compliance status is not stated in available product documentation. Verify directly with Code Blue or your carrier's equipment certification process before deploying in federal or contractor environments subject to supply-chain restrictions.
Q: Does the module support failover from cellular to a hardwired Ethernet connection?
A: Failover and dual-connectivity behavior depends on firmware configuration and system design. Some deployments use the module as primary cellular with a secondary fixed-line uplink at the edge switch; others use it as cellular-only. Consult the integration manual or your systems engineer to architect redundancy.
Q: What mounting options are available for the SLNF0174?
A: The module is typically DIN-rail or wall-mount in an electrical enclosure—specific mechanical drawings should be confirmed with the supplier before ordering brackets or backplates.
Q: What SIM cards and carriers work with the SLNF0174?
A: The module supports standard SIM cards from major North American, European, and Asia-Pacific carriers. Confirm 4G LTE band support for your region and carrier before ordering. Some integrators recommend industrial IoT SIM cards (e.g., Verizon, AT&T, Vodafone M2M plans) for better uptime and prioritization on congested networks.
I see a lot of SLNF0174 units deployed at remote job sites and small branch offices where running conduit to a core switch is not feasible. The module's IP68 rating and dual power input (120V AC mains plus 12–24V DC) make it genuine drop-in hardware for weather-sealed cabinets and outdoor electrical boxes. The real win is the PoE option—if you have a PoE switch within 100 meters, you can feed the SLNF0174 on a single cable, simplifying both power and data runs on-site.
Technical Highlights:
- IP68 Sealing: Protects cellular radio and antenna connectors from dust and splash in outdoor and temporary enclosures—critical when your cabinet is a tool box on a construction site or a weathered electrical pedestal in a parking lot.
- Dual Power Architecture (120V AC + PoE/12–24V DC): Supports mains when available, drops to battery-backed 12V DC when mains fails—eliminates single-point power failure and pairs well with solar or UPS systems on remote installs.
- Paging Amplifier Integration: Allows audio alerts and live-listen feeds to propagate over cellular back to a central station or mobile responder—useful when your remote site has no on-premises speakers or intercom system.
Deployment Considerations:
- Carrier signal strength at your remote site is make-or-break; if you're in a fringe coverage area, budget for external antennas and mounting the module as high as possible in the enclosure.
- Throughput on congested 4G networks (5–15 Mbps) is fine for one or two moderate-resolution streams but will struggle with multiple 4K cameras—test carrier coverage and available bandwidth before committing to cellular-only on high-demand sites.
Use the SLNF0174 as your primary cellular bridge for temporary job sites, retail pop-ups, and remote warehouse locations where fiber or cable is not yet in place. It's not a replacement for a hardwired switch and NVR, but it is the right gateway when those options don't exist yet.
