WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. After you connect 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 complete IP camera system, you should analysis the set up environment and investigate which functions you want to attain.
Wi-fi or PoE, which is a good? As a mature technician that has four years in video recording surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cordless sign (2.4GHz UHF group, 5GHz SHF group).
Obviously, once the IP camera helps WiFi, the camera can hook up your router without using hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, which are; every gadgets require power, that means your IP camera still requires cable television for connection.
So far, I haven't found any IP cams are able to operate with power packs.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including electric power rate of Wi-fi device, environment (inside or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters in house.
When Wi-fi devices are working outdoor without hurdle, the transmitting distance will be much very good.
To extend the Wi-fi coverage or distance, you can set up WiFi access point. Such an gain access to point (or hotspot) has a variety of about 20 meters (66 legs) 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 cable connection (Kitty5/6) is the key feature of PoE technology.
So long as your IP camera supports 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 assembly, which greatly reduced the set up procedures, and get rid of the necessity of ability cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum vitality rate is to 15.4 W of DC vitality (minimum 44V DC and 350mA) to each device.
In order to provide power for high ability ingestion 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 electric power.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negatives AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, 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 tv, there is absolutely no signal disturbance, no signal 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 much expensive when compared to a traditional network change, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, 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 Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is preferred. PoE is a lot reliable than WiFi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to control, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I came across that WiFi IP video cameras are widely used for non-professional interior home security, and PoE IP cams are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how would you determine which cordless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which kind of cellular IP camera suites and would gratify their needs. As a result, they get sucked into buying cordless IP video cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or smart); what perfection of data do you want to capture? (HD images with or without audio) & most importantly, what is your budget?
Second, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Of course, this feature will be based upon the surroundings where you intend to use the camera.
A wide pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Make sure that you check the kind of zooming ability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you'll never fail to find one with optical focus.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your neighborhood electric store.
Always obtain a test set up as this will enable you to determine the display quality of the camera.
In addition, it will offer you an opportunity to learn how to create the gear in a proper manner to make sure that you obtain the best image and audio quality.
