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


#1. NO 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 complete IP camera system, you should analysis the set up environment and investigate which functions you want to achieve.


Wireless or PoE, which is the foremost? As a older technician who has four years in video tutorial surveillance 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 transmit data through cordless indication (2.4GHz UHF group, 5GHz SHF strap).


Obviously, once the IP camera supports Wi-fi, the camera can connect your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is the advantage of Wi-fi.


But there are two downsides 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 camcorders have the ability to operate with battery power.



#3. HOW FAR Will WI-FI REACH?


Limited WiFi transmitting distance is another problem.


How far will Wi-Fi reach? It isn't 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 (indoors or outdoor) plus more.


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


When Wi-fi devices will work outdoor without barrier, the transmission distance will be much way.


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



#4. WHAT'S POE?


PoE stands for Power over Ethernet, this is not a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over sole Ethernet wire (Kitten5/6) is the primary feature of PoE technology.


So long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play unit installation, which greatly reduced the unit installation 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 vitality rate is to 15.4 W of DC electric power (bare minimum 44V DC and 350mA) to each device.


To be able to provide power for high electric power usage devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called 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 Gain access to Point

-           Network Routers

-           Industrial devices

#5. Disadvantages AND Positives OF POE TECHNOLOGY


Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra vitality cable or power.


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


For properly working of PoE devices, Electric power 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 a lot expensive than a traditional network switch, which increased a little on cost.



#6. Wi-fi VS POE


No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.

Making sure 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 Wi-fi in terms of data transmission.


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


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




So how do you really determine which cordless IP camera suits your needs?


Firstly, establish the thing you need. Many potential buyers often don't really know which kind of cellular IP camera suites and would gratify their needs. As a result, they get sucked into buying cellular IP video cameras that are beyond what they need.


Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or shiny); what detail of data do you want to get? (HD images with or without sound) and most importantly, what is your budget?


 

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


Certainly, this feature will rely upon the surroundings where you intend to use the camera.


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


Thirdly, zooming capacity for the wireless IP camera is also essential.

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


A lot of the IP cameras on the market are digital, but you'll never fail to find one with optical zoom.


Fourth, test the equipment before purchase.

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


Always request for a test installation as this will permit you to look for the display quality of the camera.


Furthermore, it will offer you an opportunity to learn how to set up the gear in an effective manner to ensure that you have the best image and music quality.
