WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?


#1. NO NEED TO USE BOTH WIFI AND PoE


Yes, you can't use both Wi-fi and PoE at same time. Once you hook up 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 unit installation environment and check out which functions you want to attain.


WiFi or PoE, which is a good? As a mature technician who has four years in video 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 cordless sign (2.4GHz UHF music group, 5GHz SHF band).


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


But there are two downsides on WiFi, that are; every gadgets require power, that means your IP camera still requires wire for connection.


Up to now, I haven't found any IP surveillance cameras are able to operate with battery power.



#3. WHAT LENGTHS DOES WI-FI REACH?


Limited WiFi transmitting distance is another problem.


What lengths does Wi-Fi reach? It isn't easy to answer this question.


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


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


When WiFi devices are working outdoor without barrier, the transmitting distance will be much significantly.


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



#4. WHAT'S POE?


PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over single Ethernet cable (Kitten5/6) is the key feature of PoE technology.


As 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 allow IP cams support plug-and-play assembly, which greatly reduced the set up 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 can offer maximum power rate is to 15.4 W of DC vitality (minimal 44V DC and 350mA) to each device.


To be able to provide power for high electric power usage devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.


PoE technology has been trusted in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Professional devices

#5. Downsides AND Benefits OF POE TECHNOLOGY


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


The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable, there is no signal disturbance, no transmission jamming.


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


A PoE switch is much expensive than a traditional network move, which increased a little on cost.



#6. WIFI VS POE


No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wireless IP camera.

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


For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmission.


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


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




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


Firstly, establish what you need. Many purchasers often don't really know which kind of cellular IP camera suites and would gratify their needs. Because of this, they get sucked into buying wireless IP video cameras 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 excellent); what detail of data do you want to capture? (HD images with or without audio tracks) and most importantly, what is your budget?


 

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


Naturally, this feature will be based upon the surroundings 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 kind of zooming capabilities, whether its optical or digital.


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


Fourth, test the equipment before purchase.

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


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


In addition, it will offer you an possibility to learn how to create the gear in a proper manner to make sure that you obtain the best image and audio tracks quality.
