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. When you connect 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 check out which functions you want to attain.
WiFi or PoE, which is best? As a mature technician who may have four years in video tutorial 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 transfer data through wireless transmission (2.4GHz UHF band, 5GHz SHF group).
Obviously, after the IP camera facilitates Wi-fi, the camera can hook up your router without using hardwired connection. Wi-fi can allow IP camera become portable, this is the advantage of WiFi.
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 battery packs.
#3. HOW FAR Does indeed 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 power rate of Wireless device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters indoors.
When WiFi devices will work outdoor without hurdle, the transmission distance will be much considerably.
To extend the WiFi coverage or distance, you can set up WiFi gain access to point. This access point (or hotspot) has a variety around 20 meters (66 legs) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet wire (Pet cat5/6) is the main feature of PoE technology.
So 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 surveillance cameras support plug-and-play assembly, which greatly reduced the set up procedures, and get rid of the necessity of power 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 power (least 44V DC and 350mA) to each device.
In order to provide power supply for high electric power consumption devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. CONS AND PROS OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable television, there is no signal interference, no indication jamming.
For properly working of PoE devices, Electric 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 swap, which increased 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.
Making sure the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to take care of, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of surveillance market, I found that WiFi IP video cameras are widely used for non-professional indoor home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you select WiFi IP Camera please read article below.
So how can you determine which cordless IP camera suits your needs?
Firstly, establish the thing you need. Many purchasers often don't really know which kind of cordless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cellular IP cams 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 shiny); what precision of data do you want to catch? (HD images with or without audio) and most importantly, what's your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Of course, this feature will be based upon the environment where you want to use the camera.
A wide skillet and tilt range is never a poor thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
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 will never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your neighborhood electric store.
Always request for a test set up as this will enable you to look for the display quality of the camera.
Furthermore, it will offer you an possibility to learn how to create the gear in a proper manner to make certain you receive the best image and audio quality.
