Operating IP cameras and access points through the TP Link TL-SG2428P PoE switch
Hi team, I'm looking at the TP Link TL-SG2428P JetStream switch with 24-Port PoE+ for my home network. I need to power 12 IP cameras and 2 access points. The spec says it delivers 250W total. Can you confirm if this is sufficient for 14 PoE devices, taking into account typical power use for cameras and APs, without any heavy-duty gear?
Hi. Each gadget requires different power levels. Could you tell us the camera and AP models you intend to use? Then we can look up their specifications and perform an accurate calculation.
If the switch supports 802.3af (PoE) and not 802.3at (PoE+), it can supply power to all 14 devices within a budget of about one or two additional PoE units. Using 15.4 watts per device for 14 units equals roughly 215 watts, which fits within the 250-watt limit. The PoE budget is capped at its maximum rating, so even low draw rates will reach the budget first.
2mp IP cams usually use up to 12 watts when night vision LEDs are on. They draw 5-7 watts in daylight. I'm a big supporter of affordable Nelly security gear with solid performance. Highly suggested if you're still deciding on a camera.
The camera count has risen as additional units are needed for full coverage. In the revised setup, I’ll install 15 IP cameras, 8 bullet 2MP, 2 bullet 4MP, and 5 indoor dome models. I’ll also link in 2 EAP225 wall APs. Could you confirm if the TP Link TL -SG2428P switch can power all 17 PoE devices?
Here are some key points to consider:
Adjust your approach by reviewing the article on PoE power options.
General details about IP cameras won’t help much.
Megapixels are irrelevant; manufacturers vary in power requirements.
Identify the specific camera model and its power needs for accuracy.
Your PoE switch’s capacity must match the total load—don’t overload it.
For future growth, consider a switch with extra ports or expandable design.
Smaller switches can work if you limit the number of devices now.
Many systems include a built-in PoE hub, but custom setups may require a dedicated switch.
keep this in mind, thanks a lot. After reading the article, I found it really useful. I discovered that a Poe+ switch supports up to 30W of power. If a device uses less power, the remaining capacity can be shared among other ports. But with more cameras and access points, I faced another issue: the total number of cables needed from ground to first floor was insufficient. My original plan was to run all cables at the first floor, but now I’m terminating cables on the ground floor itself and using a daisy chain approach. This means I’ll power ground devices through one switch and first-floor devices through another. In my updated setup, I estimate: Ground – 11 cameras; First floor – 4 cameras and 2 access points. I think I can run Power over TLS 2428p on the ground floor and TLS 2210p on the first floor. It should work for my needs. Appreciate your help!
