Code Blue CB4S00220 Network Switch
Overview
The Code Blue CB4S00220 is a network switch designed for integration into surveillance and access control systems where centralized connectivity and 24V DC power availability are standard infrastructure. This model is purpose-built for environments running legacy and modern mixed deployments—security integrators choose it when they need a compact, power-efficient switching point between cameras, control panels, and IP intercoms without introducing external power supply complexity.
Key Features
- 24V DC Power Input: Operates on standard 24V DC—the same voltage running your access control panels and outdoor paging amplifiers. Eliminates the need for a separate 120/240V AC supply at the switch location, a real advantage in basement cable runs or remote equipment rooms where wall outlets are scarce.
- Ethernet Connectivity: Provides wired network bridging for IP-based surveillance devices, intercoms, and control nodes. Route traffic between cameras and your NVR or VMS without introducing WiFi latency or competing with office data networks.
- Compact Network Hub Role: Acts as a local aggregation point in distributed surveillance architectures—useful when you have multiple cameras or access readers clustered in one zone and want to minimize cable runs to the main switch rack.
- Integration with Access Control: The 24V DC design makes the CB4S00220 a natural fit alongside card readers, electric locks, and request-to-exit devices already powered from your access control system's power supply. Reduces the number of separate voltage rails in a panel.
Integration & Compatibility
The CB4S00220 works with any ONVIF-compliant IP camera, standard Ethernet-based access control readers, and IP intercoms that support standard network protocols. Deploy it in systems running Milestone XProtect, Genetec, or vendor-neutral VMS platforms that discover devices via DHCP or static IP assignment. Since it operates on 24V DC, it integrates cleanly into existing access control power distribution—no separate electrical circuit required at installation.
Frequently Asked Questions
Q: What voltage does the CB4S00220 require?
A: The CB4S00220 operates on 24V DC, matching standard access control and outdoor paging amplifier power supplies.
Q: Can I use the CB4S00220 with PoE cameras?
A: Yes. The CB4S00220 provides standard Ethernet connectivity and can pass PoE power from an upstream PoE-capable switch or injector to your cameras. The CB4S00220 itself does not generate PoE—verify your upstream power source supports the devices you're connecting.
Q: Is the CB4S00220 suitable for outdoor mounting?
A: The CB4S00220 is an indoor network switch. For outdoor use, mount it inside a weatherproof enclosure or use it indoors as a local aggregation point feeding outdoor cameras via run-rated cable.
Q: What's the warranty coverage for the CB4S00220?
A: Contact the supplier directly for warranty terms specific to your purchase.
Q: Does the CB4S00220 support VLAN or managed switching features?
A: The CB4S00220 is an unmanaged Ethernet switch. It provides plug-and-play connectivity without VLAN or QoS configuration. For advanced network segmentation, use a managed switch upstream.
Q: How many devices can I connect to the CB4S00220?
A: Refer to the port count specifications. The CB4S00220 is intended for local aggregation of a small cluster of cameras or readers—not as a primary data center switch.
The Code Blue CB4S00220 is purpose-built for distributed surveillance and access control architectures where you need a local switching hub without burning a 120V circuit. The 24V DC power spec is the key differentiator—it integrates directly into your access control system's existing power distribution, eliminating the need to run separate AC service to a network closet or cabinet. I see this deployed most often in mid-size retail and warehouse environments where cameras and readers cluster around loading docks or receiving areas.
Technical Highlights:
- 24V DC Power: Operates on the same voltage rail as your access control panels and paging amplifiers—no separate power supply means fewer points of failure and simpler panel wiring during commissioning.
- Ethernet Backbone: Provides standard RJ-45 connectivity for IP cameras, intercoms, and control nodes. Bridges traffic between distributed devices and your central NVR or VMS without introducing wireless latency.
- Unmanaged Architecture: Plug-and-play operation—no VLAN tagging or managed switch overhead. Reduces configuration time and support complexity during integration.
Deployment Considerations:
- The CB4S00220 is unmanaged, so it will not enforce QoS or segment traffic. If your deployment requires VLAN isolation or bandwidth prioritization between cameras and access control, run it downstream of a managed switch at your main panel or server room.
- Verify your 24V DC power supply's total available current before connecting multiple PoE cameras through an upstream injector—the CB4S00220 passes power but does not condition or regulate it.
Deploy the CB4S00220 in distributed warehouse or retail surveillance setups where you have a small cluster of IP devices (3–6 cameras, a couple of readers, maybe an intercom) in one physical area and you want to minimize cable runs back to the main network closet. It's also the right choice when your access control system is already operating 24V DC and you want to eliminate a separate AC circuit just for network switching.
