Code Blue SLNF0149 CB4s 4G/LTE Cellular Expansion Module
Overview
The Code Blue SLNF0149 is a cellular expansion module designed to add 4G/LTE connectivity to Code Blue CB4s surveillance systems. This IP68-rated module bridges the gap between fixed wireline installations and mobile or remote site deployments where cellular backhaul is the only option. The SLNF0149 operates on 24V DC power via PoE (802.3af), eliminating the need for separate power infrastructure at the camera or edge location.
Key Features
- 4G/LTE Cellular Connectivity: Adds mobile broadband to CB4s deployments, critical for remote sites, temporary installations, or locations where fiber and copper backhaul are unavailable. Cellular redundancy also protects against Ethernet line cuts at retail, warehouse, or outdoor perimeter locations.
- IP68 Environmental Rating: Dust and water ingress protection to 1 meter submersion depth — suitable for outdoor equipment cabinets, pole-mounted enclosures, and weather-exposed junction boxes. IP68 confirms the module won't fail due to condensation, direct rain, or seasonal flooding of mechanical rooms.
- PoE 802.3af Power: Draws under 13W per the PoE standard, so it integrates into existing PoE switch ports without requiring dedicated 24V DC runs to remote locations. One Ethernet cable handles both data and power — simplifies field wiring and reduces installation labor.
- 24V DC Operating Voltage: Nominal 24V DC operation aligns with Code Blue's standard power ecosystem, reducing the need to stock multiple voltage regulators or converters in your parts inventory.
- Paging Amplifier Support During Production Transitions: Module design accommodates power distribution to auxiliary components like paging amplifiers during system production changeouts. The documented use of 12–24V DC during component transitions ensures backward compatibility during field upgrades or emergency repairs.
- Expansion Module Architecture: Purpose-built to extend CB4s capability without replacing core cameras or recording infrastructure. Pairs with existing wired surveillance branches to add mobile failover or primary connectivity to new remote zones.
Integration and Compatibility
The SLNF0149 is engineered as a companion module for Code Blue CB4s surveillance installations. Its PoE power draw and 24V DC native operation simplify integration into existing wired surveillance systems where PoE switches and Ethernet plant are already deployed. The cellular interface allows CB4s devices to transmit video, audio, and telemetry over 4G/LTE networks, enabling live viewing and remote management from mobile or cloud-based platforms. The module's compact form factor and IP68 seal make it suitable for equipment cabinets, outdoor wall boxes, or pole-mounted network nodes — locations where standard indoor network modules would fail within months due to humidity and condensation.
Environmental and Durability Ratings
The IP68 rating confirms complete dust protection and water resistance to submersion. This is essential for surveillance expansion modules deployed in mechanical rooms with seasonal water intrusion, outdoor electrical boxes subject to snow melt and rain splash, or humidity-prone environments like parking garage equipment closets. The module's sealed design prevents corrosion of internal cellular transceiver and modem components, extending service life and reducing field replacement rates. When paired with a weather-resistant enclosure, the SLNF0149 can operate reliably in outdoor conditions from -40°C to 60°C (typical commercial surveillance temperature range).
Power and Installation Notes
Installation requires a PoE-capable Ethernet switch port (802.3af minimum, 13W available per port). Route the Ethernet cable to the SLNF0149 location, ensuring the cable passes through conduit or is otherwise protected from physical damage and UV exposure at outdoor sites. Once powered, the module initializes its cellular modem and associates with available 4G/LTE carriers in your service area. Configuration and carrier selection are managed through Code Blue's management interface — consult your system administrator or Code Blue technical support for APN setup and roaming preferences. The module's PoE design eliminates the need to run separate 24V DC power supplies, but confirm your Ethernet switch has available 802.3af capacity before installation — high power draw from multiple modules may require an upgrade to PoE+ (802.3at) switching infrastructure.
Frequently Asked Questions
Q: Is the SLNF0149 compatible with all Code Blue camera models, or only CB4s?
A: The SLNF0149 is designed as an expansion module for Code Blue CB4s systems. Compatibility with other Code Blue models should be confirmed with Code Blue technical support, as form factor, power interfaces, and firmware requirements may differ across product lines.
Q: What is the power consumption of the SLNF0149?
A: The module operates on 24V DC via PoE (802.3af) and draws under 13W. Standard PoE switches provide sufficient power; no upgrade to PoE+ is required unless you are daisy-chaining multiple high-power modules or cameras on the same switch ports.
Q: Does the SLNF0149 support both 4G and LTE, or is it LTE-only?
A: The SLNF0149 supports both 4G and LTE cellular standards. Actual connectivity depends on carrier network availability and coverage in your deployment location. Consult your wireless carrier for coverage maps and roaming support in areas where you plan to deploy this module.
Q: Can the SLNF0149 be used outdoors without an enclosure?
A: The IP68 rating allows direct exposure to dust and water submersion to 1 meter, so outdoor mounting without an enclosure is possible. However, for long-term outdoor deployment, a weather-resistant enclosure is recommended to protect the module and any connected Ethernet cabling from UV degradation, temperature extremes, and physical impact.
Q: What wireless carriers does the SLNF0149 support?
A: The module supports standard 4G/LTE carriers. Specific carrier compatibility and roaming agreements should be verified with Code Blue support and your service provider during deployment planning.
Q: How is the SLNF0149 powered, and does it require a separate power supply?
A: The SLNF0149 is powered via PoE (802.3af) over the same Ethernet cable that carries data. No separate 24V DC power supply is required; the module draws power directly from a PoE-capable network switch. This simplifies field installation and reduces cable runs to remote locations.
The SLNF0149 solves a real deployment problem: how to add cellular failover to a wired surveillance backbone without ripping out existing infrastructure or burning budget on separate power and conditioning equipment. The PoE-powered design is the key here — you get 4G/LTE redundancy from a single Ethernet port, and the IP68 seal means it survives the mechanical rooms, equipment closets, and outdoor junction boxes where these modules actually get installed.
Technical Highlights:
- PoE 802.3af Power Draw (under 13W): Integrates into any standard PoE switch without exhausting the power budget. A single 95W PoE switch port can supply the SLNF0149 plus one or two additional powered cameras on the same circuit — critical when you're retrofitting cellular connectivity into existing deployments without switch upgrades.
- IP68 Environmental Seal: Confirms dust and water protection to 1 meter submersion. In practice, this means the module survives humidity spikes in underground parking garages, seasonal condensation in equipment cabinets, and direct rain exposure on pole-mounted network nodes. IP67 would limit you to splash only — IP68 gives you peace of mind on outdoor and semi-outdoor equipment locations.
- 24V DC Native Operation: Aligns with Code Blue CB4s power ecosystem, so your technicians reuse familiar voltage regulators and wiring practices across the system. No learning curve, no parts cross-compatibility headaches during field repairs or emergency upgrades.
Deployment Considerations:
- Confirm PoE switch capacity before installation — the SLNF0149 draws continuous power and may not play well on budget switches with aggressive power management. Review your switch power budget spreadsheet first.
- Cellular coverage varies widely by carrier and geography. Test signal strength at the planned installation location before committing to the SLNF0149 as your primary backhaul. A dead zone or spotty coverage area will render the module useless, no matter how robust the IP rating.
The SLNF0149 is the right choice for retail chains or warehouse networks that need cellular redundancy on a limited capex envelope — one Ethernet cable, one power source, no external box. If you're patching a wired site with failover for a branch location or temporary deployment, this module earns its place in your cart.
