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. When you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.

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

Wireless or PoE, which is the greatest? As a older technician who has four years in video tutorial surveillance industry, my answer 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 wireless signal (2.4GHz UHF music group, 5GHz SHF music group).

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

But there are two disadvantages on WiFi, that are; every gadgets require power supply, that means your IP camera still requires cable television for connection.

So far, I haven't found any IP camcorders are able to operate with power packs.

#3. WHAT LENGTHS Does indeed WI-FI REACH?

Limited WiFi transmitting distance is another problem.

What lengths does 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 Wi-fi device, environment (indoor or outdoor) plus more.

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

When Wireless devices will work outdoor without barrier, the transmission distance will be much considerably.

To increase the WiFi coverage or distance, you can set up WiFi access point. This access point (or hotspot) has a range around 20 meters (66 foot) 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 over one Ethernet cable television (Feline5/6) is the key feature of PoE technology.

So long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play assembly, which greatly reduced the unit installation procedures, and get rid of the necessity of power cable and offer.

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

To be able to provide power supply for high vitality utilization devices, the IEEE connection 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 trusted in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Commercial devices

#5. Drawbacks AND Advantages OF POE TECHNOLOGY

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

The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired wire, there is no signal disturbance, no transmission 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.

#6. Wi-fi VS POE

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

For several IP camera, PoE is preferred. PoE is much reliable than WiFi in terms of data transmitting.

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

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

So how would you determine which wireless IP camera suits your preferences?

Firstly, establish the thing you need. Many customers often don't really know which kind of wireless IP camera suites and would meet their needs. As a result, they get sucked into buying cellular IP cams 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 smart); what precision of data do you want to capture? (HD images with or without audio tracks) and most importantly, what's your budget?

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

Needless to say, this feature will be based upon 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 wireless IP camera is also vital.

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

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

Fourth, test the gear before purchase.

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

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

In addition, it will give you an possibility to learn how to set up the gear in an effective manner to ensure that you receive the best image and music quality.
