Yes, you can't use both Wi-fi and PoE at same time. While you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.

Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and check out which functions you want to attain.

Wi-fi or PoE, which is a good? As a mature technician that has four years in video surveillance industry, my answer to this question is PoE is the advised choice.


WiFi is a kind of wireless technology that allows network devices transfer data through cellular indication (2.4GHz UHF music group, 5GHz SHF group).

Obviously, after the IP camera supports Wireless, the camera can connect your router without using hardwired connection. Wi-fi can enable IP camera become lightweight, this is the advantage of Wi-fi.

But there are two disadvantages on WiFi, which are; every electronic devices require power, which means your IP camera still requires cable connection for connection.

So far, I haven't found any IP cameras are able to operate with batteries.


Limited WiFi transmission distance is another problem.

What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.

When talking about WiFi coverage, we've a lot of things to consider including vitality rate of Wi-fi device, environment (in house or outdoor) and more.

Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters indoor.

When Wireless devices are working outdoor without barrier, the transmitting distance will be much very good.

To increase the Wi-fi coverage or distance, you can install WiFi access point. This gain access to point (or hotspot) has a variety around 20 meters (66 ft) indoors and a larger range outdoors.


PoE stands for Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet cable (Pet cat5/6) is the main feature of PoE technology.

So long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cams support plug-and-play installation, which greatly reduced the unit installation procedures, and get rid of the necessity of power cable and supply.

Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum vitality rate is to 15.4 W of DC ability (minimum 44V DC and 350mA) to each device.

To be able to provide power for high electricity ingestion devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of ability.

PoE technology has been widely used in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Commercial devices

#5. Downsides AND Advantages OF POE TECHNOLOGY

Let's first of all discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power.

The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired wire, there is no signal disturbance, no indication jamming.

For properly working of PoE devices, Electric power sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.

A PoE switch is a lot expensive than a traditional network transition, which increased a little on cost.


No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for WiFi IP camera.

Making sure the Wireless IP camera is installed within coverage of your Wireless router.

For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in terms of data transmission.

Furthermore, an IP camera system predicated on PoE is much easier to manage, centralized ability solution becomes available e.g using uninterruptible power (UPS).

From my own investigation of security market, I came across that WiFi IP video cameras are widely used for non-professional indoor home security, and PoE IP cams are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.

So how will you determine which wireless IP camera suits your needs?

Firstly, establish what you need. Many customers often don't really know which type of wireless IP camera suites and would fulfill their needs. As a result, they get sucked into buying wireless IP cams that are beyond what they want.

Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what accuracy of data do you want to capture? (HD images with or without sound) and most importantly, what's your budget?


Second of all, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.

Naturally, this feature will be based upon the surroundings where you want to use the camera.

A broad skillet and tilt range is never a terrible thing.

Thirdly, zooming capacity for the cellular IP camera is also essential.

Make sure that you check the sort of zooming ability, whether its optical or digital.

A lot of the IP cameras in the market are digital, but you will never fail to find one with optical zoom.

Fourth, test the equipment before purchase.

That is vital, specially when you are buying from your local electronic digital store.

Always obtain a test installation as this will enable you to look for the picture quality of the camera.

Furthermore, it will give you an opportunity to learn how to set up the equipment in an effective manner to make sure that you have the best image and music quality.
