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

Before you decide to buy an IP camera or a complete IP camera system, you should analysis the set up environment and investigate which functions you want to achieve.

WiFi or PoE, which is best? As a mature technician who has four years in video recording security industry, my answer to this question is PoE is the suggested choice.


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

Obviously, once the IP camera helps WiFi, the camera can hook up your router without using hardwired connection. Wireless can permit IP camera become portable, this is actually the advantage of WiFi.

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

So far, I haven't found any IP cameras have the ability to operate with power packs.


Limited WiFi transmitting distance is another problem.

How far does 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 ability rate of Wi-fi device, environment (interior or outdoor) and more.

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

When WiFi devices will work outdoor without hurdle, the transmission distance will be much significantly.

To extend the Wi-fi coverage or distance, you can set up WiFi access point. This gain access to point (or hotspot) has a range around 20 meters (66 toes) indoors and a greater range outdoors.


PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet wire (Kitty5/6) is the key feature of PoE technology.

As long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play set up, which greatly reduced the installation procedures, and get rid of the necessity of vitality cable and supply.

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

To be able to provide power for high ability use 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 vitality.

PoE technology has been widely used in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Gain access to Point

-           Network Routers

-           Industrial devices

#5. Downsides AND Advantages OF POE TECHNOLOGY

Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra ability cable or power supply.

The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable, there is absolutely no signal disturbance, no transmission jamming.

For properly working of PoE devices, Vitality sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.

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


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

Guaranteeing the WiFi IP camera is installed within coverage of your Wi-fi router.

For several IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmitting.

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

From my personal investigation of surveillance market, I came across that Wireless IP cams are widely used for non-professional inside home security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.

So how does one determine which cellular IP camera suits your preferences?

Firstly, establish what you need. Many clients often don't really know which kind of wireless IP camera suites and would gratify their needs. As a result, they get sucked into buying wireless IP cameras 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 bright); what perfection of data do you want to get? (HD images with or without audio) and most importantly, what is your budget?


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

Needless to say, this feature will depend on the surroundings where you want to use the camera.

A wide pan and tilt range is never a terrible thing.

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

Ensure that you check the kind of zooming capabilities, whether its optical or digital.

A lot of the IP cameras on the market are digital, but you'll never fail to find one with optical focus.

Fourth, test the gear before purchase.

That is vital, particularly when you are buying from your local electric store.

Always obtain a test set up as this will permit you to determine the picture quality of the camera.

Furthermore, it will give you an opportunity to learn how to create the gear in a proper manner to make certain you find the best image and audio tracks quality.
