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 Wireless and PoE at same time. If you hook up 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 installation environment and investigate which functions you want to accomplish.


Wi-fi or PoE, which is the best? As a older technician who may have four years in training video surveillance industry, my answer to this question is PoE is the recommended choice.



#2. WHAT'S WIFI


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


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


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


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



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


Limited WiFi transmission distance is another problem.


How far does Wi-Fi reach? It's not easy to answer this question.


When talking about WiFi coverage, we've a lot of things to consider including power rate of Wireless device, environment (inside or outdoor) and much more.


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


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


To increase the Wi-fi coverage or distance, you can mount WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 ft) indoors and a greater range outdoors.



#4. WHAT'S POE?


PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable television (Kitten5/6) is the key feature of PoE technology.


So long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play unit installation, which greatly reduced the assembly procedures, and get rid of the necessity of ability cable and offer.


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


To be able to provide power for high electricity usage devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.


PoE technology has been trusted in:

-           IP security system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Professional devices

#5. Negative aspects AND Positives 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, no need extra ability cable or power supply.


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


For properly working of PoE devices, Vitality sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.


A PoE switch is a lot expensive when compared to a traditional network turn, which increased 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 opt for Wireless IP camera.

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


For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmitting.


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


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




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


Firstly, establish what you need. Many customers often don't really know which kind of cellular 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 located in? (Hallway, outdoor, low light or smart); what perfection of data would you like to record? (HD images with or without music) and most importantly, what is your budget?


 

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


Certainly, this feature will rely upon the surroundings where you would like to use the camera.


A broad skillet and tilt range is never an awful thing.


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

Ensure that you check the type of zooming potential, 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 zoom.


Fourth, test the equipment before purchase.

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


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


In addition, it will give you an opportunity to learn how to create the gear in a proper manner to make certain you find the best image and music quality.
