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


#1. YOU DON'T NEED TO USE BOTH Wireless 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 these, either Wi-fi or PoE.


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


Wireless or PoE, which is best? As a older technician who has four years in video recording monitoring industry, my response to this question is PoE is the advised choice.



#2. WHAT'S WIFI


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


Obviously, once the IP camera facilitates Wireless, the camera can connect your router without using hardwired connection. Wireless can enable IP camera become portable, this is actually the advantage of Wireless.


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


So far, I haven't found any IP video cameras have the ability to operate with batteries.



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


Limited WiFi transmitting distance is another problem.


What lengths will Wi-Fi reach? It's not easy to answer this question.


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


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


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


To increase the WiFi coverage or distance, you can set up WiFi access point. This gain access to point (or hotspot) has a variety around 20 meters (66 ft) indoors and a greater range outdoors.



#4. WHAT'S POE?


PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable connection (Cat5/6) is the key feature of PoE technology.


As long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play unit installation, which greatly reduced the set up procedures, and eliminate the necessity of ability cable and offer.


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


In order to provide power for high electric power utilization devices, the IEEE association 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 security system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Professional devices

#5. Negatives AND Advantages OF POE TECHNOLOGY


Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable tv, 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 connection, there is absolutely no signal disturbance, no indication jamming.


For properly working of PoE devices, Power sourcing equipment (PSE) is vital 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 move, which increased a little on cost.



#6. Wireless 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 Wireless IP camera.

Making sure the Wireless IP camera is installed within coverage of your WiFi router.


For more than one IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmitting.


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


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




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


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


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


 

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


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


A broad skillet and tilt range is never a bad thing.


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

Ensure that you check the type of zooming functionality, 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 move.


Fourth, test the gear before purchase.

This is vital, especially when you are buying from your neighborhood electronic store.


Always obtain a test installation as this will allow you to look for the picture quality of the camera.


Furthermore, it will offer you an chance to learn how to create the gear in an effective manner to ensure that you receive the best image and sound quality.
