WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wireless and PoE at same time. After you connect the IP camera to your router, you have to choose one of them, 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 accomplish.
Wireless or PoE, which is the best? As a mature technician that has four years in video security 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 indication (2.4GHz UHF group, 5GHz SHF strap).
Obviously, after the IP camera facilitates Wi-fi, the camera can hook up your router without needing hardwired connection. Wireless can permit IP camera become portable, this is the advantage of WiFi.
But there are two drawbacks on WiFi, which are; every electronic devices require power, that means your IP camera still requires wire for connection.
So far, I haven't found any IP cams are able to operate with battery packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths will Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electric power rate of WiFi device, environment (in house or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters in house.
When Wi-fi devices are working outdoor without hurdle, the transmitting distance will be much way.
To extend the Wi-fi coverage or distance, you can mount WiFi gain access to point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for 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 supply over single Ethernet wire (Feline5/6) is the key 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 permit IP camcorders support plug-and-play set up, which greatly reduced the assembly 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 power (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high ability ingestion devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Negative aspects AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra electricity cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is no signal interference, no sign 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 much expensive than a traditional network swap, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wireless IP camera.
Making sure the WiFi 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 terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wi-fi IP surveillance cameras are trusted for non-professional indoor security, and PoE IP cams are installed for outdoor security system. But if you choose WiFi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish the thing you need. Many potential buyers often don't really know which kind of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying wireless IP camcorders that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or smart); what precision of data would you like to record? (HD images with or without music) and most importantly, what's your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Obviously, this feature will rely upon the environment where you want to use the camera.
A wide pan and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the cellular IP camera is also vital.
Ensure that you check the type of zooming functionality, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never fail to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, especially when you are buying from your local electric store.
Always request for a test installation as this will permit you to look for the display quality of the camera.
In addition, it will offer you an opportunity to learn how to create the gear in an effective manner to make certain you find the best image and music quality.
