WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?

#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE

Yes, you can't use both Wireless and PoE at same time. After you hook up 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 whole IP camera system, you should analysis the set up environment and investigate which functions you want to achieve.

WiFi or PoE, which is the greatest? As a mature technician that has four years in video tutorial monitoring industry, my response to this question is PoE is the recommended choice.

#2. WHAT'S WIFI

WiFi is some sort of wireless technology which allows network devices transfer data through cordless signal (2.4GHz UHF strap, 5GHz SHF band).

Obviously, once the IP camera facilitates Wireless, the camera can hook up your router without using hardwired connection. WiFi can allow IP camera become portable, this is the advantage of Wi-fi.

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

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

#3. WHAT LENGTHS Will WI-FI REACH?

Limited WiFi transmission distance is another problem.

How far will Wi-Fi reach? It's not easy to answer this question.

When discussing WiFi coverage, we've many things to consider including electricity rate of Wi-fi device, environment (interior or outdoor) and much more.

Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters inside.

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

To extend the WiFi coverage or distance, you can set up WiFi gain access to point. Such an access point (or hotspot) has a variety around 20 meters (66 toes) indoors and a larger range outdoors.

#4. WHAT'S POE?

PoE means 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 supply over one Ethernet cable connection (Cat5/6) is the key feature of PoE technology.

As long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play unit installation, which greatly reduced the set up procedures, and eliminate the necessity of electric power cable and offer.

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

In order to provide power supply for high electric power utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as 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

-           Industrial devices

#5. Negatives AND Advantages OF POE TECHNOLOGY

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

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

For properly working of PoE devices, Electricity 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 when compared to a traditional network switch, which increased a little on cost.

#6. WIFI VS POE

No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.

Ensuring the WiFi IP camera is installed within coverage of your WiFi router.

For more than one IP camera, PoE is preferred. PoE is a lot reliable than WiFi in terms of data transmitting.

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

From my personal investigation of security market, I came across that Wireless IP video cameras are trusted for non-professional indoor home security, and PoE IP video cameras are installed for outdoor security system. But if you select WiFi 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 kind of cellular IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cellular IP camcorders that are beyond what they need.

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 shiny); what detail of data do you want to capture? (HD images with or without sound) and most importantly, what is your budget?

 

Secondly, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.

Obviously, this feature will be based upon the environment where you intend to use the camera.

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

Thirdly, zooming capability of the wireless IP camera is also essential.

Ensure that you check the type of zooming capabilities, 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 focus.

Fourth, test the gear before purchase.

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

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

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