WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. When you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and check out which functions you want to attain.
WiFi or PoE, which is a good? As a senior technician who has four years in video security industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cellular transmission (2.4GHz UHF band, 5GHz SHF music group).
Obviously, once the IP camera supports Wi-fi, the camera can hook up your router without using hardwired connection. WiFi can permit IP camera become portable, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which can be; every electronic devices 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 electric batteries.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including electric power rate of Wireless device, environment (indoor 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 WiFi devices will work outdoor without hurdle, the transmission distance will be much significantly.
To extend the WiFi coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a range around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over solo Ethernet cable connection (Kitten5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and get rid of the necessity of electricity cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electricity rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
To be able to provide power for high vitality intake 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 electricity.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. CONS AND Positives OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable television, no need extra electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable television, there is no signal interference, no signal jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is essential component, it's rather 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 swap, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is much reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to manage, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that WiFi IP cams are trusted for non-professional in house home security, and PoE IP video cameras are installed for outdoor surveillance system. But if you choose Wi-fi IP Camera please read article below.
So how would you determine which wireless 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 gratify their needs. Because of this, they get sucked into buying cordless IP cams 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 glowing); what accuracy of data do you want to get? (HD images with or without sound) & most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Certainly, this feature will be based upon the environment where you intend to use the camera.
A broad pan and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Ensure that you check the sort of zooming functionality, whether its optical or digital.
A lot of the IP cameras on 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 local electronic digital store.
Always obtain a test setup as this will enable you to determine the display quality of the camera.
Furthermore, it will give you an chance to learn how to set up the gear in a proper manner to ensure that you get the best image and music quality.
