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 WiFi and PoE at same time. Whenever 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 unit installation environment and check out which functions you want to achieve.


Wireless or PoE, which is the greatest? As a mature technician who may have four years in video surveillance industry, my answer to this question is PoE is the suggested choice.



#2. WHAT'S WIFI


WiFi is a kind of wireless technology which allows network devices transfer data through cellular transmission (2.4GHz UHF group, 5GHz SHF group).


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


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


Up to now, I haven't found any IP cameras are able to operate with electric batteries.



#3. HOW FAR DOES 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 talking about WiFi coverage, we've a lot of things to consider including power rate of WiFi device, environment (indoors or outdoor) and more.


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


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


To extend the Wi-fi coverage or distance, you can set up WiFi access 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 is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable (Kitty5/6) is the main 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 permit IP cams support plug-and-play unit installation, which greatly reduced the assembly procedures, and eliminate the necessity of electricity cable and supply.


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


To be able to provide power supply for high electric power ingestion 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 electric power.


PoE technology has been widely used in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Commercial devices

#5. Negatives AND Benefits 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 connection, no need extra vitality cable or power supply.


The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired wire, there is no signal disturbance, no signal 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 much expensive than a traditional network turn, which increased a little on cost.



#6. Wireless VS POE


No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.

Guaranteeing the Wireless IP camera is installed within coverage of your Wireless router.


For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless in conditions of data transmitting.


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


From my personal investigation of security market, I found that WiFi IP cams are widely used for non-professional indoor home security, and PoE IP cameras are installed for outdoor security system. But if you select Wireless IP Camera please read article below.




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


Firstly, establish what you need. Many potential buyers often don't really know which type of cellular IP camera suites and would satisfy their needs. As a result, they get sucked into buying cellular IP camcorders that are beyond what they want.


Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or shiny); what precision of data would you like to capture? (HD images with or without audio tracks) & most importantly, what is your budget?


 

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


Of course, this feature will be based upon the surroundings where you want to use the camera.


A broad skillet and tilt range is never an undesirable thing.


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

Ensure that you check the sort of zooming capabilities, 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 move.


Fourth, test the equipment before purchase.

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


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


In addition, it will give you an chance to learn how to set up the gear in a proper manner to make sure that you get the best image and sound quality.
