WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. While 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 set up environment and research which functions you want to achieve.
WiFi or PoE, which is the greatest? As a mature technician who has four years in video tutorial security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cellular sign (2.4GHz UHF music group, 5GHz SHF band).
Obviously, after the IP camera helps Wi-fi, the camera can hook up your router without needing hardwired connection. WiFi can allow IP camera become portable, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, which are; every electronic devices require power, that means your IP camera still requires cable connection for connection.
So far, I haven't found any IP surveillance cameras have the ability to operate with batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've many 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 provide WiFi coverage extends to up to 10 meters interior.
When WiFi devices are working outdoor without hurdle, the transmitting distance will be much significantly.
To increase the WiFi coverage or distance, you can install WiFi gain access to point. Such an gain access to point (or hotspot) has a range around 20 meters (66 legs) 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 over solo Ethernet wire (Kitty5/6) is the main feature of PoE technology.
As long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play installation, which greatly reduced the set up procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability 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 ability ingestion 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 vitality.
PoE technology has been widely used 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 features of PoE. A PoE IP camera can get the energy from the Ethernet cable, no need extra power 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 interference, no indication jamming.
For properly working of PoE devices, Vitality 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 a lot expensive than a traditional network transition, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Ensuring the Wireless IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of surveillance market, I found that Wi-fi IP camcorders are widely used for non-professional in house security, and PoE IP video cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how can you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many purchasers often don't really know which kind of wireless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cellular 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 excellent); what perfection of data do you want to get? (HD images with or without audio) & most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Obviously, this feature will be based upon the surroundings where you want to use the camera.
A broad skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Make sure that you check the sort of zooming functionality, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never neglect to find one with optical move.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your neighborhood digital store.
Always obtain a test setup as this will allow you to look for the picture quality of the camera.
Furthermore, it will give you an possibility to learn how to set up the gear in a proper manner to make certain you receive the best image and sound quality.
