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 Wireless and PoE at same time. After 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 assembly environment and check out which functions you want to accomplish.


Wireless or PoE, which is the foremost? As a older technician that has four years in video recording monitoring industry, my answer to this question is PoE is the suggested choice.



#2. WHAT'S WIFI


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


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


But there are two downsides on WiFi, which are; every electronic devices require power, which means your IP camera still requires cable for connection.


So far, I haven't found any IP video cameras are able to operate with battery packs.



#3. HOW FAR Will 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 a lot of things to consider including ability rate of Wi-fi device, environment (interior or outdoor) and even more.


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


When Wireless devices are working outdoor without barrier, the transmission distance will be much far.


To increase the Wi-fi coverage or distance, you can set up WiFi access point. Such an access point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a greater 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 supply over solo Ethernet wire (Cat5/6) is the key feature of PoE technology.


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


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 vitality (minimal 44V DC and 350mA) to each device.


To be able to provide power supply for high vitality use 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 trusted in:

-           IP security system ( Camera + NVR)

-           VoIP Phones

-           WiFi Gain access to Point

-           Network Routers

-           Professional devices

#5. Negatives AND PROS 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 tv, no need extra vitality cable or power supply.


The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired wire, there is no signal disturbance, no indication jamming.


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



#6. Wireless VS POE


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

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


For several IP camera, PoE is recommended. PoE is a lot reliable than Wireless in terms of data transmission.


Furthermore, an IP camera system predicated 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 surveillance market, I found that Wireless IP surveillance cameras are widely used for non-professional indoor home security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.




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


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


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


 

Second, another essential feature to consider before sometimes a radio IP camera is the pan 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 a negative thing.


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

Ensure that you check the type of zooming functionality, whether its optical or digital.


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


Fourth, test the gear before purchase.

That is vital, in particular when you are buying from your local digital store.


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


In addition, it will offer you an chance to learn how to create the gear in a proper manner to make certain you get the best image and audio tracks quality.
