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


#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE


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


Prior to deciding 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 attain.


Wireless or PoE, which is the better? As a mature technician who have four years in training video monitoring industry, my response to this question is PoE is the suggested choice.



#2. WHAT'S WIFI


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


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


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


Up to now, I haven't found any IP cams have the ability to operate with electric batteries.



#3. WHAT LENGTHS Does indeed WI-FI REACH?


Limited WiFi transmission distance is another problem.


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


When talking about WiFi coverage, we have a lot of things to consider including electricity rate of WiFi device, environment (in house or outdoor) plus more.


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


When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much considerably.


To extend the Wi-fi coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a range of about 20 meters (66 feet) 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 solitary Ethernet cable television (Kitty5/6) is the primary feature of PoE technology.


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


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


To be able to provide power supply for high vitality 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 ability.


PoE technology has been trusted in:

-           IP monitoring system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Commercial devices

#5. CONS AND Advantages OF POE TECHNOLOGY


Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power supply.


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


For properly working of PoE devices, Ability 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 when compared to a traditional network swap, 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 WiFi IP camera.

Guaranteeing the Wi-fi IP camera is installed within coverage of your Wi-fi router.


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


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


From my personal investigation of surveillance market, I found that WiFi IP camcorders are trusted for non-professional indoor security, and PoE IP camcorders are installed for outdoor security system. But if you select Wi-fi IP Camera please read article below.




So how does one determine which cellular IP camera suits your preferences?


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


Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what accuracy of data would you like to record? (HD images with or without audio) and most importantly, what's your budget?


 

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


Obviously, this feature will depend on the environment where you intend to use the camera.


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


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

Make sure that you check the type of zooming capability, whether its optical or digital.


Most of the IP cameras on the market are digital, but you will never fail to find one with optical zoom.


Fourth, test the equipment before purchase.

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


Always request for a test set up as this will enable you to look for the display quality of the camera.


In addition, it will offer you an possibility to learn how to set up the equipment in an effective manner to ensure that you obtain the best image and audio quality.
