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. Once you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and investigate which functions you want to attain.
WiFi or PoE, which is the foremost? As a mature 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 that allows network devices transmit data through cellular transmission (2.4GHz UHF group, 5GHz SHF music group).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without using hardwired connection. Wi-fi can enable IP camera become portable, this is actually the advantage of Wireless.
But there are two downsides on WiFi, that are; every gadgets require power supply, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP video cameras have the ability to operate with power packs.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've many things to consider including ability rate of Wireless device, environment (inside or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters interior.
When WiFi devices will work outdoor without hurdle, the transmitting distance will be much considerably.
To extend the Wi-fi coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a range around 20 meters (66 toes) indoors and a larger 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 supply over sole Ethernet cable (Feline5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play assembly, which greatly reduced the unit installation 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 provides maximum electricity rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
To be able to provide power for high electric power ingestion 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 widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. CONS AND PROS OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable television, there is no signal disturbance, no indication jamming.
For properly working of PoE devices, Electricity 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 than a traditional network swap, which increased just a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Making sure the Wi-fi 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 WiFi in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to take care of, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I found that Wi-fi IP surveillance cameras are widely used for non-professional indoors home security, and PoE IP video cameras are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how do you determine which cordless IP camera suits your needs?
Firstly, establish the thing you need. Many potential buyers often don't really know which kind of wireless IP camera suites and would satisfy their needs. As a result, they get sucked into buying wireless 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 glowing); what detail of data do you want to get? (HD images with or without sound) and most importantly, what is your budget?
Subsequently, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Naturally, this feature will rely upon the environment where you intend to use the camera.
A broad pan and tilt range is never a negative thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Make sure that you check the kind of zooming ability, whether its optical or digital.
Most 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.
That is vital, in particular when you are buying from your local electric store.
Always request for a test set up as this will enable you to look for the picture quality of the camera.
In addition, it will offer you an chance to learn how to set up the gear in a proper manner to ensure that you receive the best image and music quality.
