ip network security cameras You should read article below before you buy IP Camera.



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

Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and investigate which functions you want to achieve.

Wireless or PoE, which is the best? As a mature technician who have four years in training video security industry, my answer to this question is PoE is the recommended choice.


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

Obviously, once the IP camera helps Wireless, the camera can connect your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is actually the advantage of WiFi.

But there are two drawbacks on WiFi, that are; every gadgets require power, which means your IP camera still requires cable tv for connection.

Up to now, I haven't found any IP cams have the ability to operate with battery power.


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 many things to consider including vitality rate of Wireless device, environment (interior or outdoor) and much more.

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

When Wi-fi devices will work outdoor without hurdle, the transmitting distance will be much considerably.

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


PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over one Ethernet cable connection (Feline5/6) is the key feature of PoE technology.

So long as your IP camera facilitates PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP camcorders support plug-and-play unit installation, which greatly reduced the assembly 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 provides maximum electric power rate is to 15.4 W of DC vitality (least 44V DC and 350mA) to each device.

To be able to provide power supply for high electricity usage 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 power.

PoE technology has been trusted in:

-           IP surveillance system ( Camera + NVR)

-           VoIP Phones

-           WiFi Gain access to Point

-           Network Routers

-           Professional devices

#5. Downsides AND Positives OF POE TECHNOLOGY

Let's firstly discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra electric power cable or power.

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

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

A PoE switch is a lot expensive when compared to a traditional network turn, 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 choose to use Wi-fi IP camera.

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

For several IP camera, PoE is recommended. PoE is much reliable than Wireless in conditions of data transmission.

Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power (UPS).

From my personal investigation of security market, I found that WiFi IP surveillance cameras are trusted for non-professional interior home security, and PoE IP surveillance cameras are installed for outdoor surveillance system. But if you select WiFi IP Camera please read article below.

So how does one determine which wireless IP camera suits your needs?

Firstly, establish the thing you need. Many buyers often don't really know which kind of wireless IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless IP camcorders that are beyond what they need.

Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or smart); what precision of data would you like to catch? (HD images with or without music) & most importantly, what is your budget?


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

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

A broad pan and tilt range is never a negative thing.

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

Ensure that you check the sort of zooming functionality, whether its optical or digital.

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

Fourth, test the gear before purchase.

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

Always request for a test setup as this will permit you to determine the display quality of the camera.

In addition, it will offer you an opportunity to learn how to create the equipment in an effective manner to ensure that you obtain the best image and music quality.
