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


#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE


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


Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and research which functions you want to achieve.


WiFi or PoE, which is the better? As a senior technician that has four years in training video security industry, my answer to this question is PoE is the advised choice.



#2. WHAT'S WIFI


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


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


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


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



#3. WHAT LENGTHS Will 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 have many things to consider including ability rate of Wi-fi device, environment (indoors or outdoor) and more.


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


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


To increase the WiFi coverage or distance, you can mount WiFi access point. Such an 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 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 (Cat5/6) is the primary feature of PoE technology.


As long as your IP camera supports PoE, you just need to connect 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 set up procedures, and get rid of the necessity of vitality 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 electricity (minimum 44V DC and 350mA) to each device.


To be able to provide power for high 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 vitality.


PoE technology has been trusted in:

-           IP surveillance system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Industrial devices

#5. Drawbacks AND PROS OF POE TECHNOLOGY


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


The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable tv, there is no signal interference, 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 than a traditional network move, which increased a little on cost.



#6. WIFI 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.

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


For more than one 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 manage, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).


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




So how do you determine which cellular IP camera suits your needs?


Firstly, establish the thing you need. Many potential buyers often don't really know which type of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP 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 dazzling); what detail of data would you like to take? (HD images with or without audio) & most importantly, what's your budget?


 

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


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


A broad skillet 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 kind of zooming capacity, whether its optical or digital.


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


Fourth, test the equipment before purchase.

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


Always request for a test setup as this will enable you to look for the picture quality of the camera.


Furthermore, it will give you an opportunity to learn how to set up the gear in an effective manner to make sure that you find the best image and sound quality.
