WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wi-fi and PoE at same time. After you hook up the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and check out which functions you want to attain.
WiFi or PoE, which is the greatest? As a senior technician who may have four years in training video security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through wireless transmission (2.4GHz UHF group, 5GHz SHF music group).
Obviously, once the IP camera facilitates Wi-fi, the camera can connect your router without using hardwired connection. Wi-fi can permit IP camera become lightweight, this is actually the advantage of Wi-fi.
But there are two downsides on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cams have the ability to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far will 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 Wireless device, environment (indoor or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters inside.
When WiFi devices are working outdoor without barrier, the transmission distance will be much significantly.
To extend the Wi-fi coverage or distance, you can set up WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 legs) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet cable (Kitty5/6) is the key feature of PoE technology.
As long as your IP camera facilitates PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP camcorders support plug-and-play assembly, which greatly reduced the assembly procedures, and eliminate the necessity of ability 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 ability (minimum 44V DC and 350mA) to each device.
To be able to provide power for high vitality 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 Gain access to Point
- Network Routers
- Commercial devices
#5. Negatives AND PROS OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra electricity cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electricity 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 much expensive when compared to a traditional network move, which increased just a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use Wireless 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 much reliable than Wi-fi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I came across that WiFi IP video cameras are widely used for non-professional indoor home security, and PoE IP cams are installed for outdoor security system. But if you select Wi-fi 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 type of cellular IP camera suites and would satisfy their needs. Because of this, they get sucked into buying cordless IP surveillance cameras 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 shiny); what accuracy of data do you want to capture? (HD images with or without music) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Needless to say, this feature will rely upon the surroundings where you intend to use the camera.
A broad pan and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the type of zooming capabilities, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your local electronic digital store.
Always obtain a test setup as this will permit you to look for the display quality of the camera.
In addition, it will offer you an possibility to learn how to set up the gear in an effective manner to make sure that you receive the best image and audio quality.
