WIFI OR PoE FOR IP CAMERA, WHICH IS 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. If you connect the IP camera to your router, you have to choose one of these, 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 research which functions you want to achieve.
Wireless or PoE, which is a good? As a senior technician who may have four years in video tutorial security industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through wireless signal (2.4GHz UHF music group, 5GHz SHF group).
Obviously, once the IP camera facilitates WiFi, the camera can connect your router without using hardwired connection. Wireless can allow IP camera become portable, this is the advantage of Wireless.
But there are two drawbacks on WiFi, which can be; every electronic devices require power supply, that means your IP camera still requires cable connection for connection.
So far, I haven't found any IP video cameras have the ability to operate with battery packs.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including power rate of WiFi device, environment (in house or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage grows to up to 10 meters in house.
When Wireless devices are working outdoor without hurdle, the transmitting distance will be much much.
To increase the WiFi coverage or distance, you can mount WiFi access point. This access point (or hotspot) has a variety around 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over single Ethernet cable television (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera facilitates PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP surveillance cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum vitality rate is to 15.4 W of DC vitality (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high power use devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negative aspects AND Advantages OF POE TECHNOLOGY
Let's firstly 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 connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electricity 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 swap, which increased a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wi-fi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to control, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of security market, I came across that Wi-fi IP cameras are widely used for non-professional indoors 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 does one determine which wireless IP camera suits your preferences?
Firstly, establish what you need. Many potential buyers often don't really know which kind of cellular IP camera suites and would meet their needs. Because of this, they get sucked into buying cellular IP cams that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or bright); what accuracy of data do you want to record? (HD images with or without sound) and most importantly, what's your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Obviously, this feature will rely upon the surroundings where you want to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Make sure 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 fail to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your local electronic digital store.
Always request for a test set up as this will allow you to determine the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the gear in a proper manner to make sure that you get the best image and music quality.
