WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. After you hook up the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the installation environment and investigate which functions you want to achieve.
WiFi or PoE, which is best? As a senior technician who have four years in video monitoring industry, my answer 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 wireless transmission (2.4GHz UHF music group, 5GHz SHF strap).
Obviously, once the IP camera supports Wi-fi, the camera can hook up your router without needing hardwired connection. Wi-fi can enable IP camera become lightweight, this is the advantage of Wireless.
But there are two downsides on WiFi, which are; every gadgets require power, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP video cameras have the ability to operate with batteries.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have many things to consider including vitality rate of Wireless device, environment (in house or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters indoor.
When WiFi devices are working outdoor without barrier, the transmitting distance will be much much.
To extend the WiFi coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a range of about 20 meters (66 foot) 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 was launched by Cisco in 1999. Transmitting both data and power supply over sole Ethernet cable connection (Kitty5/6) is the key feature of PoE technology.
So 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 allow IP surveillance cameras support plug-and-play set up, which greatly reduced the installation procedures, and eliminate the necessity of power cable and supply.
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.
To be able to provide power for high electric power use devices, the IEEE association 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 security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Downsides 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, no need extra vitality cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is absolutely no signal disturbance, 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 a lot expensive than a traditional network transition, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than WiFi in conditions of data transmitting.
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 supply (UPS).
From my personal investigation of security market, I came across that Wireless IP surveillance cameras are trusted for non-professional indoors security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how do you really determine which cordless IP camera suits your preferences?
Firstly, establish the thing you need. Many buyers often don't really know which type of cordless IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless IP cameras 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 dazzling); what detail of data would you like to capture? (HD images with or without sound) & most importantly, what's your budget?
Subsequently, 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 would like 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.
Make sure that you check the kind of zooming capability, 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, specially when you are buying from your neighborhood digital store.
Always obtain a test installation as this will permit you to look for the picture quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the gear in a proper manner to make certain you get the best image and music quality.
