WIFI OR PoE FOR IP CAMERA, WHICH IS 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. Whenever you hook up 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 whole IP camera system, you should analysis the set up environment and investigate which functions you want to accomplish.

Wi-fi or PoE, which is the better? As a older technician who has four years in video tutorial monitoring industry, my response to this question is PoE is the suggested choice.

#2. WHAT'S WIFI

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

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

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

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

#3. WHAT LENGTHS DOES WI-FI REACH?

Limited WiFi transmission distance is another problem.

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

When discussing WiFi coverage, we have a lot of things to consider including ability rate of Wireless device, environment (interior or outdoor) and much more.

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

When Wireless devices are working outdoor without hurdle, the transmitting distance will be much considerably.

To extend the Wireless coverage or distance, you can install WiFi gain access to point. Such an access point (or hotspot) has a variety around 20 meters (66 foot) indoors and a greater range outdoors.

#4. WHAT'S POE?

PoE stands for Power over Ethernet, this is not a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over sole Ethernet cable (Feline5/6) is the primary feature of PoE technology.

As long as your IP camera facilitates PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play assembly, which greatly reduced the set up procedures, and get rid of the necessity of electricity cable and offer.

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 electricity (bare minimum 44V DC and 350mA) to each device.

In order to provide power supply for high electricity consumption devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.

PoE technology has been widely used in:

-           IP surveillance system ( Camera + NVR)

-           VoIP Phones

-           WiFi Gain access to Point

-           Network Routers

-           Commercial devices

#5. Drawbacks AND Positives 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 interconnection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired wire, there is absolutely no signal disturbance, no sign 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 when compared to a traditional network change, which increased a little on cost.

#6. Wireless VS POE

No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.

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

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

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

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

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

Firstly, establish what you need. Many customers often don't really know which kind of cordless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cellular IP video 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 accuracy of data would you like to get? (HD images with or without audio tracks) & most importantly, what's your budget?

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

Needless to say, this feature will be based upon the environment where you would like to use the camera.

A wide pan and tilt range is never an undesirable thing.

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

Make sure that you check the type of zooming capability, whether its optical or digital.

Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical zoom.

Fourth, test the equipment before purchase.

This is vital, especially when you are buying from your neighborhood electronic digital store.

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

In addition, it will offer you an opportunity to learn how to create the gear in an effective manner to ensure that you get the best image and audio tracks quality.
