Code Blue SLNF0295 4G/LTE Cellular Expansion Module
Overview
The Code Blue SLNF0295 is a cellular expansion module designed to extend surveillance system connectivity to remote or mobile sites where traditional hardwired network infrastructure is impractical. This module adds 4G/LTE backup or primary transport to Code Blue surveillance deployments, enabling real-time video and alarm transmission from edge locations. The SLNF0295 is IP68-rated for outdoor installation and accepts either 24V DC or PoE (802.3af) power, eliminating the need for dual power supplies in mixed-architecture sites.
Key Features
- 4G/LTE Cellular Connectivity: Adds mobile broadband transport when fixed-line Ethernet or fiber are unavailable. Ideal for temporary deployments, mobile units, or sites in rural coverage areas where laying new cabling is cost-prohibitive.
- IP68 Enclosure Rating: Fully sealed against dust and submersion up to 1 meter for 30 minutes. Suitable for rooftop antenna mounts, pole installations, or other outdoor-exposed positions without protective housing.
- Dual Power Input (24V DC / PoE 802.3af): Accepts either hardwired 24V DC or standard PoE power, reducing installation overhead when retrofitting into existing networks. PoE eliminates the need for a separate power supply if your switch has available budget.
- Expansion Module Form Factor: Designed as a standalone unit to pair with existing Code Blue surveillance platforms, minimizing footprint on shared mounting hardware or cabinet space.
- Paging Amplifier Support: Compatible with paging audio infrastructure during production. Power requirements scaled to 12-24V DC operation to support both primary and backup audio alerting in emergency response scenarios.
- Remote Site Flexibility: Enables deployments where VPN tunneling over cellular is preferred over fixed-line networks, or where redundant backup connectivity is required for critical surveillance chains.
Integration & Compatibility
The SLNF0295 is engineered as an expansion module within the Code Blue ecosystem. It integrates with Code Blue surveillance management platforms and supports standard cellular carrier SIM provisioning. The module's 24V DC and PoE dual input design allows it to operate in mixed power architectures—install it on the same PoE switch as IP cameras or pair it with existing 24V DC supply rails already serving Code Blue access control or paging systems. Confirm carrier SIM compatibility and local spectrum availability before deployment.
Environmental and Durability Ratings
IP68 protection ensures the SLNF0295 survives outdoor weather without additional enclosure. Operating temperature range and seal integrity make this unit suitable for unattended remote installations. The sealed design also resists tampering and environmental contamination, important for public-facing or high-security perimeter deployments.
Power and Installation Notes
The module draws power via either a hardwired 24V DC connection or standard PoE (802.3af) injection. Installers should verify PoE budget on their switch before committing multiple expansion modules to a single port bank; each unit's power draw under load will depend on cellular signal strength and data throughput. For sites requiring paging amplifier operation, ensure your 24V DC supply can sustain both the SLNF0295 and audio load simultaneously. Antenna placement is critical for 4G/LTE signal strength—mount the cellular antenna on the highest unobstructed point to maximize coverage and data throughput.

Frequently Asked Questions
Q: Does the SLNF0295 work as a primary connection or backup-only failover?
A: The module is designed to function as either primary or secondary transport depending on your network architecture. It can serve as the main surveillance link for remote sites or as redundant backup for critical locations where Ethernet outages demand continuous cellular fallback.
Q: What is the warranty on the SLNF0295?
A: Warranty terms are not specified in current documentation. Contact pre-sales engineering for manufacturer warranty details and extended coverage options.
Q: Can I power the SLNF0295 from my PoE switch, or do I need a separate 24V supply?
A: The SLNF0295 accepts both PoE (802.3af) and 24V DC input. If your PoE switch has available power budget (typically 15W per port), PoE is simpler. Otherwise, a 24V DC supply will work. Verify your switch's total PoE budget if deploying multiple modules.
Q: Is the SLNF0295 NDAA Section 889 compliant?
A: NDAA compliance status is not documented for this model. If Section 889 compliance is mandatory for your project, contact pre-sales engineering to verify eligibility.
Q: What cellular carriers and frequency bands are supported?
A: Supported carriers and bands depend on the SIM provisioning and local spectrum availability. Consult Code Blue documentation or pre-sales engineering for approved carriers in your region.
Q: How do I mount the SLNF0295 in the field?
A: The module is IP68-rated for outdoor installation. Mounting hardware and antenna placement guidance are not specified in available documentation. Contact pre-sales engineering for detailed installation instructions and mounting bracket options.
The SLNF0295 solves a real field problem: getting video and alarms back from sites where there's no Ethernet run and running cable is either impossible or expensive. I've worked cellular failover into systems for years, and the dual power input on this module—PoE and 24V DC—is what makes it actually deployable. You're not forced to maintain two separate power schemas on the same site.
Technical Highlights:
- IP68 Rating: Seals against dust and water immersion, which means you can mount it outdoors on a pole or rooftop antenna mast without adding an enclosure. One less thing to engineer in the field.
- PoE 802.3af + 24V DC Input: Pick whichever power rail is already in your network. If you've got PoE budget on your switch, use it. If you're running 24V DC to paging amps or door locks, tap that instead. No forced infrastructure changes.
- 4G/LTE Cellular Primary or Backup: Deploys as your main transport for truly remote sites (rural, temporary, mobile units) or as automatic failover when your primary Ethernet or fiber drops. Real flexibility in how you architect the link.
Deployment Considerations:
- Antenna placement is critical—heights and line-of-sight directly control your data throughput. A rooftop or tower mount beats closet installation by orders of magnitude for signal strength.
- SIM provisioning and carrier selection happen before you ship the unit. Confirm your regional carriers and 4G/LTE bands are compatible; swapping carriers mid-deployment eats time you don't have in the field.
This module is the right fit for remote oil and gas sites, rural water treatment facilities, and mobile surveillance trailers where fixed infrastructure is not an option. If you're building a surveillance network in areas without fiber or hardened Ethernet, the SLNF0295 moves you from impossible to done.
