WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wireless and PoE at same time. Whenever you connect 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 whole IP camera system, you should analysis the unit installation environment and research which functions you want to achieve.
Wireless or PoE, which is the best? As a older technician who has four years in video tutorial monitoring industry, my response 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 cordless sign (2.4GHz UHF band, 5GHz SHF group).
Obviously, once the IP camera supports Wireless, the camera can hook up your router without needing hardwired connection. Wireless can enable IP camera become lightweight, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, that happen to be; every electronic devices require power supply, which means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cameras have the ability to operate with battery packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have a lot of things to consider including electric power rate of WiFi device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters in house.
When WiFi devices are working outdoor without hurdle, the transmitting distance will be much much.
To increase the Wireless coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a range 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 supply over single Ethernet cable connection (Feline5/6) is the main feature of PoE technology.
So long as your IP camera helps PoE, you just 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 installation, which greatly reduced the assembly procedures, and get rid of the necessity of ability 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 ability (bare minimum 44V DC and 350mA) to each device.
To be able to provide power supply for high 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 electric power.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet cable connection, 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 wire, there is no signal interference, no transmission jamming.
For properly working of PoE devices, Electricity 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 when compared to a traditional network transition, which increased a little on cost.
#6. Wireless 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 WiFi IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to control, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I found that Wireless IP video cameras are widely used for non-professional indoors home security, and PoE IP cameras are installed for outdoor surveillance system. But if you choose WiFi IP Camera please read article below.
So how can you determine which cordless IP camera suits your preferences?
Firstly, establish the thing you need. Many potential buyers often don't really know which type of wireless IP camera suites and would meet their needs. As a result, they get sucked into buying wireless IP video 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 accuracy of data would you like to capture? (HD images with or without sound) & most importantly, what is your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Needless to say, this feature will depend on the surroundings where you intend to use the camera.
A wide pan and tilt range is never a negative thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
Ensure that you check the kind of zooming capability, 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 zoom.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your neighborhood electronic store.
Always obtain a test set up as this will enable you to determine the picture quality of the camera.
In addition, it will give you an opportunity to learn how to set up the gear in a proper manner to ensure that you find the best image and audio tracks quality.
