WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. Once 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 assembly environment and investigate which functions you want to attain.
Wireless or PoE, which is the better? As a older technician who have four years in video monitoring industry, my response 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 wireless indication (2.4GHz UHF band, 5GHz SHF band).
Obviously, once the IP camera supports WiFi, the camera can connect your router without using hardwired connection. Wireless can permit IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, that happen to be; every electronic devices require power, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP cams are able to operate with battery packs.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including electricity rate of WiFi device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) can offer WiFi coverage grows to up to 10 meters indoors.
When WiFi devices are working outdoor without barrier, the transmission distance will be much way.
To extend the WiFi coverage or distance, you can set up WiFi access point. This access point (or hotspot) has a variety around 20 meters (66 feet) indoors and a greater 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 solo Ethernet cable (Kitten5/6) is the main 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 cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and eliminate the necessity of electricity cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electric power rate is to 15.4 W of DC electricity (minimum amount 44V DC and 350mA) to each device.
To be able to provide power supply for high ability ingestion devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired wire, there is no signal interference, no sign 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 much expensive than a traditional network switch, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is preferred. PoE is a lot reliable than WiFi in terms of data transmission.
Furthermore, an IP camera system based on PoE is a lot easier to control, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wi-fi IP video cameras are widely used for non-professional in house home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you choose Wireless IP Camera please read article below.
So how does one determine which wireless IP camera suits your needs?
Firstly, establish what 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 cordless IP video cameras that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or smart); what precision of data would you like to take? (HD images with or without audio) and most importantly, what's your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Of course, this feature will be based upon the environment where you would like to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the kind of zooming capability, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, specially when you are buying from your local electric store.
Always obtain a test installation as this will permit you to look for the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to create the equipment in a proper manner to make sure that you have the best image and audio tracks quality.
