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. After you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the unit installation environment and investigate which functions you want to achieve.
WiFi or PoE, which is the greatest? As a older technician who may have four years in video recording surveillance industry, my response to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cellular signal (2.4GHz UHF band, 5GHz SHF group).
Obviously, after the IP camera facilitates Wi-fi, the camera can connect your router without using hardwired connection. Wi-fi can enable IP camera become portable, this is the advantage of Wi-fi.
But there are two downsides on WiFi, which are; every electronic devices require power supply, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP camcorders are able to operate with power packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electricity rate of Wi-fi device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters inside.
When Wi-fi devices are working outdoor without hurdle, the transmission distance will be much considerably.
To increase the WiFi coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a variety of about 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over one Ethernet cable television (Feline5/6) is the main feature of PoE technology.
So long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cams support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electricity rate is to 15.4 W of DC power (bare minimum 44V DC and 350mA) to each device.
In order to provide power for high electric power use devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of power.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Positives OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable connection, there is absolutely no signal interference, no indication jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is essential 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 switch, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you wish 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 Wi-fi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of surveillance market, I found that WiFi IP cameras are widely used for non-professional indoor home security, and PoE IP cameras are installed for outdoor surveillance system. But if you choose WiFi IP Camera please read article below.
So how can you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many purchasers often don't really know which kind of cellular IP camera suites and would meet their needs. As a result, they get sucked into buying cellular IP surveillance cameras that are beyond what they need.
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 dazzling); what perfection of data do you want to catch? (HD images with or without audio) and most importantly, what is your budget?
Second, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Naturally, this feature will rely upon the surroundings where you would like to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Make sure that you check the kind of zooming capability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never fail to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your local electronic store.
Always obtain a test set up as this will enable you to determine the picture quality of the camera.
In addition, 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 quality.
