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


#1. NO NEED TO USE BOTH Wireless AND PoE


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


Wi-fi or PoE, which is the better? As a older technician that has four years in video recording security industry, my response to this question is PoE is the recommended choice.



#2. WHAT'S WIFI


WiFi is some sort of wireless technology that allows network devices transfer data through cellular indication (2.4GHz UHF strap, 5GHz SHF music group).


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


But there are two disadvantages on WiFi, which can be; every electronic devices require power supply, that means your IP camera still requires wire for connection.


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



#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've many things to consider including ability rate of Wi-fi device, environment (indoor or outdoor) and much more.


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


When Wireless devices will work outdoor without hurdle, the transmitting distance will be much much.


To increase the Wireless coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 legs) 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 solo Ethernet cable tv (Cat5/6) is the main feature of PoE technology.


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


In order to provide power supply for high ability consumption 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 electricity.


PoE technology has been trusted in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Industrial devices

#5. Negative aspects AND Positives OF POE TECHNOLOGY


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


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


For properly working of PoE devices, Electricity 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 when compared to a traditional network move, which increased just a little on cost.



#6. Wi-fi VS POE


No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for WiFi IP camera.

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


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


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


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




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


Firstly, establish what you need. Many clients often don't really know which type of cordless IP camera suites and would gratify their needs. As a result, they get sucked into buying cordless 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 situated in? (Hallway, outdoor, low light or smart); what perfection of data do you want to record? (HD images with or without audio) & most importantly, what is your budget?


 

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


Of course, this feature will rely upon the environment where you would like to use the camera.


A wide pan and tilt range is never a negative thing.


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

Make sure that you check the sort of zooming capacity, 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 move.


Fourth, test the gear before purchase.

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


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


In addition, it will offer you an opportunity to learn how to create the gear in a proper manner to ensure that you receive the best image and audio quality.
