WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both WiFi and PoE at same time. When you connect 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 unit installation environment and research which functions you want to achieve.
WiFi or PoE, which is the best? As a older technician who have four years in video monitoring industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cordless transmission (2.4GHz UHF band, 5GHz SHF music group).
Obviously, after the IP camera helps Wireless, the camera can hook up your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, which are; every gadgets require power supply, that means your IP camera still requires wire for connection.
So far, I haven't found any IP video cameras have the ability to operate with power packs.
#3. WHAT LENGTHS DOES 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 many things to consider including electricity rate of WiFi device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage extends to up to 10 meters interior.
When Wi-fi devices will work outdoor without barrier, 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 range around 20 meters (66 legs) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over sole Ethernet cable connection (Cat5/6) is the main feature of PoE technology.
As 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 installation, which greatly reduced the installation procedures, and get rid of the necessity of electricity cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC electricity (lowest 44V DC and 350mA) to each device.
To be able to provide power supply for high electricity use devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. CONS AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable television, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network change, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to take care of, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of security market, I found that Wi-fi IP camcorders are widely used for non-professional in house home security, and PoE IP cams are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many potential buyers often don't really know which type of cellular IP camera suites and would gratify their needs. Because of this, they get sucked into buying cordless IP video 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 excellent); what perfection of data do you want to take? (HD images with or without music) & most importantly, what is your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Needless to say, this feature will be based upon the surroundings where you would like to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the kind 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 zoom.
Fourth, test the equipment before purchase.
That is vital, in particular when you are buying from your local electric store.
Always obtain a test setup as this will allow you to look for the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the equipment in an effective manner to make sure that you receive the best image and music quality.
