24-Port PoE Switches
Quick answer
A 24-port PoE switch powers 24 cameras only if they are 6 W domes — the budget, not the port count, sets the real number. With 400 W that is roughly 13–17 W per port depending on the reserve kept, and with 300 W roughly 10–12 W. Both budgets are pooled: a few 25 W PTZ heads decide the loading long before the 24th port is used.
Twenty-four powered ports is the largest single unit in this range, and the one where the budget arithmetic decides the product. Twenty-four ports loaded at the 802.3at limit is 720 W — far beyond any unit here, which is why the budget line matters more than the port count.
The 4 models in this size run 300–400 W, in 100M and gigabit versions, with uplink arrangements for the run back to the core.

How to choose
- Know the realistic per-port draw. 24 ports with a 400 W supply averages about 16.6 W per port if every port is loaded — enough for fixed domes, not for PTZ heads on every port.
- Budget first, then enclosure. The 400 W units are full 486 mm rack width with two SFP slots; the 300 W units are 310 mm deep with one SFP slot and fit a smaller wall cabinet.
- Uplink capacity. 24 cameras at 4 Mbps is under 100 Mbps of aggregate, but multi-sensor cameras and NVR playback change that; gigabit access ports and SFP uplinks are the safe default at this size.
- Uptime. A single 24-port unit is a single point of failure for the whole floor. Where that matters, two 16-port units split the risk.
How many devices will each model actually power?
Calculated from the published budget of each model with a 20% reserve kept for PoE start-up surge, IR load at night and ageing. The figure is capped by the powered-port count, so it never promises more devices than there are ports. Budgets are pooled — one 25 W PTZ takes what several 6 W domes would.

Which of the four 24-port models fits your site
The four models are not three budget tiers of one product — they are two chassis sizes crossed with two access speeds. That makes the choice short: pick the chassis by budget and cabinet space, then pick access speed by what the cameras and the NVR need.
| Site condition | Model | Why |
|---|---|---|
| 24 cameras, mixed domes and PTZ, full-width rack | HX-2404PEG | 400 W budget, 24 gigabit access ports, 24+2+2 with two SFP slots, 486 mm rack width |
| Same load, but camera ports must be isolated at layer 2 | HX-2404PE | 400 W and two SFP slots on 100M access ports, with the panel VLAN isolation switch fitted |
| Mostly fixed domes on 100M, smaller wall cabinet | HX-X2403PE | 300 W budget, 310 mm chassis, 24+2+1 with one SFP slot, VLAN isolation switch fitted |
| Mostly fixed domes, gigabit access, smaller cabinet | HX-X2403PEG | 300 W budget, gigabit access, 310 mm chassis, 24+2+1 with one SFP slot |
If the site is close to the 300 W limit, buy the 400 W model: the difference is cheaper than a second switch when a fourth PTZ is added two years later. Run your camera count and draw through the PoE budget calculator to see which of the four covers it with the reserve kept.
Managed or unmanaged at 24 ports
Every model in this range is unmanaged. It stands up, powers what is plugged into it and forwards traffic; the panel switch on some models isolates the camera ports from the uplink at layer 2, which is a wiring convenience rather than a management interface.
That covers most CCTV and AP installations, because segmentation is normally done at the core switch or the NVR. It does not cover an IT department that expects a web interface, per-port VLAN assignment, SNMP polling or a ring protocol — for those, the managed switch belongs upstream and this unit stays the powered edge.
- Unmanaged edge + managed core — the usual design when the site already has an IT network.
- Unmanaged everywhere — common on smaller camera-only networks where the NVR is the only other device.
- Managed features you would lose — VLAN tables, SNMP monitoring, LACP, ERPS ring recovery, per-port power scheduling. If the project specification names any of these, they have to be met at the core, not here.
The longer comparison, including what each management feature costs in a camera network, is in managed vs unmanaged PoE switch.
One 24-port unit or two 16-port units?
One unit is cheaper, needs one mains feed and one uplink, and gives a single configuration to document. Two 16-port units split the failure domain: a dead switch takes out half the floor rather than all of it, and camera runs are shorter if the cameras are physically in two places.
The deciding factor is usually uptime policy, not price. Where the site has an SLA that treats one recorder outage as an incident, the second unit pays for itself the first time a power supply fails. Where the cameras cover a yard or a shop floor and a day of downtime is tolerable, one 24-port unit is the sensible purchase.
Both approaches land in the same range — see the 16-port models for the split design and the capacity table above for the budget arithmetic on each chassis.
Frequently asked
How many cameras will a 24-port switch actually power?
Depends on the mix, not the count. With 400 W, fixed domes at 6 W fit all 24 ports with headroom and 25 W PTZ heads are limited to about twelve; with 300 W the same PTZ load fits nine. Add the labels up at peak and keep 20% spare — the capacity table above does that per model.
Is one 24-port unit better than two 16-port units?
One unit is cheaper and simpler. Two units split the failure domain and shorten cable runs if the cameras are in two places — which usually matters more than the price difference.
Do these support 802.3bt?
The switches in this range deliver the 802.3af/at power classes on the (1/2)+, (3/6)- pair arrangement, with budgets up to 400 W per unit. A 60 W or 90 W bt device is powered by a bt injector — the 60 W and 90 W standard injectors in the range are specified for 802.3af/at/bt — rather than by the switch port. Tell us the device and the port count and we will say which combination works.
What is the difference between HX-2404PE and HX-2404PEG?
Access speed and the VLAN switch. HX-2404PE has 100M access ports and the panel VLAN isolation switch fitted; HX-2404PEG has 10/100/1000Base-T access ports and no VLAN switch. Both are 24+2+2 with a 400 W budget and two 1000Base-X SFP slots.
How much heat does a 400 W PoE switch produce in a cabinet?
Budget for the full supply at peak: a 24-port unit loaded to 400 W of PoE is dissipating most of that as heat inside the cabinet, plus its own conversion losses. Treat cabinet ventilation as part of the installation, not an afterthought — an enclosed 400 W unit on a hot day is the usual cause of unexplained reboots.
Can a 24-port PoE switch be rack mounted?
The 400 W models are 486 × 190 × 44 mm, which is 19-inch rack width in a 1U form factor with the panel handles; the 300 W models are 310 × 180 × 45 mm and fit a wall cabinet. Mounting hardware is quoted with the order.
What is the PoE budget if only 12 ports are used?
The budget does not change — it is a property of the power supply, not of the port count. Using twelve ports leaves more headroom per port, so it is safe to put a 25 W PTZ on each of them; loading all twenty-four at 25 W is what breaks a 300 W or 400 W unit.
What happens if the total draw exceeds the budget?
The switch will not deliver more than its supply can produce: devices at the end of the priority order are refused power at start-up or drop out under load, which on a camera site shows up as cameras that reboot at dusk when IR and heaters come on. Size to the sum of the labels at peak, with the reserve.
