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


#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE


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


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


Wi-fi or PoE, which is best? As a mature technician that has four years in video recording monitoring industry, my answer to this question is PoE is the recommended choice.



#2. WHAT'S WIFI


WiFi is some sort of wireless technology that allows network devices transmit data through cordless signal (2.4GHz UHF music group, 5GHz SHF music group).


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


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


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



#3. HOW FAR Does indeed WI-FI REACH?


Limited WiFi transmitting distance is another problem.


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


When talking about WiFi coverage, we've many things to consider including power rate of Wireless device, environment (interior or outdoor) and more.


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


When WiFi devices will work outdoor without barrier, the transmitting distance will be much much.


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



#4. WHAT'S POE?


PoE stands for 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 supply over one Ethernet cable (Pet cat5/6) is the key feature of PoE technology.


So 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 cameras support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of electric power cable and supply.


Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability 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 ability intake 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 power.


PoE technology has been widely used in:

-           IP surveillance system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Commercial devices

#5. Disadvantages AND PROS OF POE TECHNOLOGY


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


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


For properly working of PoE devices, 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 swap, 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 opt for WiFi IP camera.

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


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


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


From my own investigation of surveillance market, I found that Wi-fi IP cams are widely used for non-professional in house security, and PoE IP surveillance cameras are installed for outdoor security system. But if you select Wireless IP Camera please read article below.




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


Firstly, establish the thing you need. Many buyers often don't really know which type of cordless IP camera suites and would meet their needs. Because of this, they get sucked into buying wireless IP cams that are beyond what they want.


Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or shiny); what perfection of data do you want to catch? (HD images with or without sound) & most importantly, what's your budget?


 

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


Certainly, this feature will depend on the surroundings where you intend to use the camera.


A broad pan and tilt range is never an awful thing.


Thirdly, zooming capability of the cordless IP camera is also vital.

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


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


Fourth, test the gear before purchase.

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


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


Furthermore, it will offer you an opportunity to learn how to create the equipment in an effective manner to make sure that you get the best image and audio quality.
