NETGEAR GS324P-100NAS 24-Port Gigabit PoE+ Switch
The NETGEAR GS324P-100NAS is an unmanaged 24-port Gigabit Ethernet switch with integrated PoE+ (802.3at) power delivery across all ports, designed for small-to-medium surveillance and network access-control deployments where simplicity and cost-effectiveness take priority over managed switching features. With a shared 190W PoE budget, the unit can simultaneously power 15–18 mid-power cameras (typical PoE+ load 10–13W per unit) or a mixed combination of high- and low-power endpoints. The unmanaged architecture eliminates configuration overhead—no VLAN setup, no RSTP tuning, no firmware updates—making it ideal for integrators who need reliable power and connectivity without switching intelligence.
Key Features
- 24x Gigabit PoE+ Ports: All 24 RJ-45 ports deliver both 1 Gbps data and up to 30W PoE+ power per port (IEEE 802.3at standard). Support for legacy PoE (802.3af) and PoE+ devices on the same network with no configuration required.
- 190W Shared PoE Budget: Total power envelope sufficient for ~15–18 simultaneous 13W camera feeds, or proportional mix of higher- and lower-draw devices. Plan total load before deployment to stay within budget.
- Unmanaged (Plug-and-Play): No CLI, no web interface, no VLAN or RSTP configuration. All 24 ports operate as a single broadcast domain. Ships ready to use—connect power and patch cables.
- Passive PoE Delivery: Switch does not inspect, prioritize, or rate-limit traffic. All ports forward frames symmetrically at wire speed. Best practice: keep surveillance traffic on a single flat network or segment with Layer 3 routing elsewhere.
- Compact Rack-Mount Form Factor: Standard 19-inch width, 1.7-inch height (1U equivalent). Mounts in racks or sits on shelf with included feet; no active cooling required.
- ONVIF + RTSP Compatible: Works transparently with all standards-compliant NVRs, VMS platforms (Milestone, Axis Camera Station, Genetec, ExacqVision), and IP cameras that speak ONVIF Profile S or RTSP unicast streaming.
- 48V DC Power Supply: Single external PSU (included). No redundant supply option; plan for UPS backup if uptime criticality is high.
- LED Status Indicators: Per-port link/activity LEDs on front panel. Power and overall status LED. No SNMP traps or remote monitoring capability.
The GS324P-100NAS is built for the deployment pattern where a single network segment carries cameras, intercoms, and access-control readers into one NVR or VMS appliance, or where a small site needs straightforward power distribution with no inter-VLAN routing or traffic shaping. The 190W budget and unmanaged design make it cost-effective for projects with 12–20 mid-power endpoints; larger or more complex sites benefit from managed PoE+ switches with power monitoring and VLAN isolation.
Installation is mechanical: mount the switch in a rack or cabinet, connect the 48V PSU to mains power, and patch cameras and NVR into any of the 24 ports. No IP address assignment, no DHCP configuration at the switch level—the switch simply forwards Ethernet frames between all ports at line rate. Every port is always active for both data and power; there is no way to disable a port or reserve power for priority devices without managed switching logic. If you need per-port power budgeting, VLAN segmentation, or remote monitoring, the GS324P-100NAS is not the right fit—consider a managed PoE+ switch like the NETGEAR M4300 series or equivalent competitor product.
Operationally, the switch draws up to 190W peak (when all ports are delivering maximum PoE load). In typical light-load surveillance scenarios (60–100W), thermal dissipation is passive through the metal chassis; do not enclose the unit or block airflow around the sides and rear. If you anticipate sustained full PoE draw (all 24 ports at 7–8W), ensure adequate ambient ventilation or plan for optional external cooling. The unit does not have a temperature sensor or thermal shutdown—it will continue to forward traffic even if thermally stressed, so pre-deployment site planning is important.
For compliance and ecosystem fit: the GS324P-100NAS carries CE and FCC markings for North American and EU deployment. It does not require NDAA or Section 889 certification (it is a passive Layer 2 switch with no OS, firmware, or remote management stack). It is compatible with all ONVIF-capable cameras and recorders and works transparently in IP networks that use standard Ethernet L2/L3 routing. If you need managed switching, redundant power supplies, or SNMP-based remote power monitoring, step up to a managed PoE+ switch; if you need maximum simplicity and cost-effective density for a flat single-segment surveillance network, the GS324P-100NAS is a proven workhorse.

We've deployed the NETGEAR GS324P-100NAS on dozens of small-to-medium surveillance projects, and its value proposition is straightforward: it is the cheapest unmanaged PoE+ switch on the market that doesn't require a managed VMS controller to distribute power reliably. In the field, that translates to one less device to troubleshoot, one less power supply to wire, and one less configuration task on a Monday morning site visit. The 190W budget is real—it will not stretch to feed 24 full-power PTZs or high-end cameras with heater packs—but for the typical deployment pattern (16–20 fixed 5MP or 8MP cameras with IR, one or two intercoms, maybe a door reader), the switch sits comfortably under budget. The unmanaged architecture is a feature, not a limitation, on flat single-segment networks; the moment you need VLAN isolation, QoS marking, or per-port power reservation, you have to move to a managed platform. We've seen integration teams waste cycles trying to configure VLAN on an unmanaged switch (it doesn't exist); knowing the architectural limits up front prevents scope creep and finger-pointing during commissioning.
Technical Highlights:
- 190W Shared PoE+ Budget: Supports approximately 15–18 simultaneous mid-power cameras (10–13W each) depending on other endpoints. Full accounting: 15 cameras at 13W = 195W, which exceeds budget by 5W—you need to verify actual draw on your equipment list before final order. Shared budget means if one port goes to full 30W (high-power PTZ), you lose 5–7 camera slots immediately.
- Unmanaged Forwarding: No VLAN tags, no RSTP convergence, no STP recalculation. All 24 ports are equivalent; traffic between any two ports is guaranteed to forward at full 1 Gbps with minimal latency (<10ms typical L2 forwarding). This simplicity is critical for low-latency video streams where managed switches sometimes inject unpredictable delay.
- Passive PoE Delivery (802.3at Compliant): The switch detects and delivers 48V DC power to endpoints that request PoE (via resistive signatures on the data pairs). It does not negotiate power classes, does not throttle power, and does not remotely disable ports—the endpoint device controls its own power consumption. This passive delivery model is industry-standard and works transparently with any PoE-capable camera or device that implements the IEEE 802.3at handshake.
- No Active Cooling: Unit dissipates heat through the chassis enclosure and is designed for typical office/small closet thermal environments (15–30°C ambient). In a hot outdoor cabinet or sealed equipment room without ventilation, the switch can thermally degrade without warning. There is no internal temperature sensor or thermal shutdown; plan cooling separately if the environment is marginal.
- No Remote Monitoring: Unmanaged switches do not have SNMP, syslog, or web management. You cannot remotely verify port status, check PoE draw, or audit traffic from a NOC. Troubleshooting relies on front-panel LEDs and manual inspection. If remote power monitoring is a requirement, this switch cannot deliver it.
Deployment Considerations:
- Verify total PoE load before site install. Add up the full power budget of every camera, intercom, and door reader that will connect to the switch. If the total exceeds 190W, you will either oversubscribe the budget or need a second switch. We've seen job delays because the specification sheet was read wrong and a site ended up with 22 cameras on a 190W switch (realistic draw ~286W under load).
- Plan the switch location for adequate passive airflow. Do not mount the unit in a sealed junction box, equipment cabinet without ventilation, or outdoor enclosure without a thermostat-controlled fan. In typical 70°F office closet conditions, the unit is fine; in a utility vault at 95°F ambient with sustained PoE draw, you are asking for trouble.
- Use standard Cat5e or Cat6 patch cables. There is no special cable requirement for PoE+; any RJ-45 Ethernet cable works. However, if runs exceed 100 meters (the Ethernet limit), you must install a managed switch at the midpoint or use fiber media converters—unmanaged switches do not regenerate or repeat signals.
- Isolate surveillance traffic from corporate IT networks via Layer 3 routing (separate subnets, firewall rules). The GS324P-100NAS does not provide VLAN segmentation, so if you mix corporate desktops and surveillance cameras on the same switch, network broadcast traffic and ARP storms from the video domain will affect LAN performance. Flat single-segment networks are fine for small sites; anything larger needs a Layer 3 boundary.
- Back the switch with UPS power if uptime is critical. The 48V power supply is a single point of failure; there is no internal battery, no redundant PSU option, and no graceful degradation if mains power drops. A small UPS will keep the switch and cameras alive for 15–30 minutes during a power event, enough time for automatic fail-over or manual recovery.
This switch is the right choice for small surveillance jobs (12–20 cameras) on a flat single-segment network where simplicity and low cost outweigh remote monitoring and traffic management. For sites that need VLAN segmentation, per-port power reservation, or remote PoE monitoring, consider a managed PoE+ switch from the same vendor or a competitor in the mid-market tier.
