WIFI OR PoE FOR IP CAMERA, WHICH IS 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 WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and investigate which functions you want to accomplish.
Wi-fi or PoE, which is the foremost? As a older technician who may have four years in video monitoring industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through wireless signal (2.4GHz UHF band, 5GHz SHF band).
Obviously, after the IP camera helps WiFi, the camera can hook up your router without using hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, that are; every gadgets require power supply, which means your IP camera still requires cable for connection.
So far, I haven't found any IP video cameras are able to operate with battery packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have many things to consider including vitality rate of Wi-fi device, environment (indoor or outdoor) and more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters interior.
When Wireless devices are working outdoor without hurdle, the transmission distance will be much way.
To extend the WiFi coverage or distance, you can install WiFi access point. This access point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over sole Ethernet cable tv (Feline5/6) is the main feature of PoE technology.
As long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP cameras support plug-and-play assembly, 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 power (least 44V DC and 350mA) to each device.
To be able to provide power supply for high ability consumption 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 electricity.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Drawbacks AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable connection, no need extra electric power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable tv, there is no signal interference, no signal jamming.
For properly working of PoE devices, Vitality 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 much expensive than a traditional network move, which increased a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wi-fi 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 a lot reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is a lot easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I came across that Wi-fi IP camcorders are widely used for non-professional indoors home security, and PoE IP video cameras are installed for outdoor security system. But if you choose WiFi IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many 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 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 shiny); what accuracy of data do you want to take? (HD images with or without sound) and most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Needless to say, this feature will depend on the environment where you want to use the camera.
A broad pan and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Make sure that you check the sort of zooming capabilities, 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 gear before purchase.
This is vital, in particular when you are buying from your local digital store.
Always obtain a test set up as this will enable you to determine the picture quality of the camera.
In addition, it will offer you an chance to learn how to create the gear in a proper manner to make certain you get the best image and music quality.
