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 Wireless and PoE at same time. Once you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and check out which functions you want to accomplish.
Wi-fi or PoE, which is the better? As a senior technician who has 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 which allows network devices transfer data through wireless transmission (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, once the IP camera helps Wi-fi, the camera can connect your router without using hardwired connection. Wireless can allow IP camera become portable, this is actually the advantage of WiFi.
But there are two drawbacks on WiFi, that are; every gadgets require power, that means your IP camera still requires cable for connection.
So far, I haven't found any IP video cameras are able to operate with battery power.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have a lot of things to consider including electric power rate of Wi-fi device, environment (indoor or outdoor) and more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters indoor.
When WiFi devices are working outdoor without barrier, the transmission distance will be much way.
To increase the WiFi coverage or distance, you can set up WiFi access point. This access point (or hotspot) has a variety around 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable (Kitty5/6) is the main feature of PoE technology.
As long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP video cameras support plug-and-play set up, which greatly reduced the installation procedures, and get rid of the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum vitality rate is to 15.4 W of DC vitality (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high electric power usage 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 electricity.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Disadvantages AND Positives OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable television, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, 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 a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Making sure 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 predicated on PoE is much easier to manage, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I found that Wi-fi IP cameras are trusted for non-professional indoor home security, and PoE IP surveillance cameras are installed for outdoor surveillance system. But if you choose WiFi 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 cellular IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless IP camcorders 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 smart); what perfection of data do you want to record? (HD images with or without sound) & most importantly, what's your budget?
Secondly, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Of course, this feature will be based upon the environment where you intend to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Make sure that you check the type of zooming capabilities, 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, especially when you are buying from your local electronic store.
Always request for a test installation as this will enable you to look for the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the gear in an effective manner to ensure that you get the best image and music quality.
