WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. If you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the installation environment and investigate which functions you want to accomplish.
Wireless or PoE, which is the greatest? As a mature technician who may have four years in video surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through cellular transmission (2.4GHz UHF strap, 5GHz SHF band).
Obviously, after the IP camera supports Wi-fi, the camera can connect your router without needing hardwired connection. WiFi can permit IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, which can be; every electronic devices require power supply, which means your IP camera still requires cable tv for connection.
So far, I haven't found any IP surveillance cameras are able to operate with battery packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've many things to consider including power rate of Wi-fi device, environment (indoor or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters interior.
When WiFi devices will work outdoor without hurdle, the transmitting distance will be much much.
To increase the WiFi coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety of about 20 meters (66 toes) 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 supply over sole Ethernet cable television (Kitty5/6) is the primary 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 permit IP cams support plug-and-play unit installation, which greatly reduced the unit installation procedures, and get rid of the necessity of power cable and supply.
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 vitality (least 44V DC and 350mA) to each device.
To be able to provide power for high electric power 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 power.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable tv, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Power 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 a lot expensive when compared to a traditional network transition, which increased a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions 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 surveillance market, I came across that Wi-fi IP cams are widely used for non-professional inside home security, and PoE IP video cameras are installed for outdoor security system. But if you select WiFi 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 clients often don't really know which kind of cellular 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 situated in? (Hallway, outdoor, low light or excellent); what perfection of data would you like to record? (HD images with or without audio) 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.
Of course, this feature will depend on the surroundings where you want to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the kind of zooming ability, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, in particular when you are buying from your local electric store.
Always request for a test set up as this will allow you to determine the picture quality of the camera.
In addition, it will offer you an possibility to learn how to create the gear in a proper manner to ensure that you find the best image and music quality.
