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 WiFi and PoE at same time. Once you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the unit installation environment and check out which functions you want to achieve.
Wi-fi or PoE, which is the better? As a older technician who has four years in video recording surveillance industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cordless transmission (2.4GHz UHF music group, 5GHz SHF band).
Obviously, once the IP camera facilitates WiFi, the camera can connect your router without needing hardwired connection. WiFi can enable IP camera become portable, this is actually the advantage of WiFi.
But there are two disadvantages on WiFi, that are; every gadgets require power supply, which means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP cams have the ability to operate with batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does indeed 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 Wireless device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters in house.
When WiFi devices are working outdoor without hurdle, the transmitting distance will be much considerably.
To extend the WiFi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a range of about 20 meters (66 foot) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means 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 solo Ethernet wire (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cams support plug-and-play assembly, which greatly reduced the assembly procedures, and eliminate the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electricity rate is to 15.4 W of DC vitality (minimal 44V DC and 350mA) to each device.
To be able to provide power supply for high electricity consumption devices, the IEEE relationship 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 widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Negative aspects AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra electricity cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable television, there is absolutely no signal disturbance, no indication jamming.
For properly working of PoE devices, Ability sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network move, which increased just a little on cost.
#6. WIFI 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 Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I found that WiFi IP video cameras are widely used for non-professional indoor security, and PoE IP video cameras are installed for outdoor surveillance system. But if you choose Wireless IP Camera please read article below.
So how does one determine which cordless IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which kind of wireless IP camera suites and would fulfill their needs. As a result, they get sucked into buying wireless IP surveillance cameras that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or shiny); what precision of data do you want to get? (HD images with or without sound) and most importantly, what's your budget?
Subsequently, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Naturally, this feature will rely upon the environment where you intend to use the camera.
A broad skillet and tilt range is never an undesirable thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Make sure that you check the kind of zooming functionality, 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 move.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your neighborhood digital store.
Always request for a test setup as this will permit you to look for the picture quality of the camera.
Furthermore, it will give you an possibility to learn how to create the equipment in a proper manner to make sure that you have the best image and music quality.
