WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. After you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the installation environment and research which functions you want to achieve.
Wi-fi or PoE, which is best? As a older technician who may have 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 which allows network devices transfer data through wireless indication (2.4GHz UHF band, 5GHz SHF band).
Obviously, once the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. Wi-fi can allow IP camera become portable, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, that are; every gadgets require power, that means your IP camera still requires wire for connection.
So far, I haven't found any IP video cameras have the ability to operate with batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've many things to consider including power rate of Wireless device, environment (interior or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters in house.
When WiFi devices are working outdoor without hurdle, the transmission distance will be much significantly.
To increase the Wi-fi coverage or distance, you can mount WiFi gain access to point. Such an gain access to point (or hotspot) has a variety around 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over single Ethernet cable tv (Pet cat5/6) is the key feature of PoE technology.
So 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 camcorders support plug-and-play installation, which greatly reduced the installation procedures, and get rid of the necessity of electric power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum vitality rate is to 15.4 W of DC electric power (least 44V DC and 350mA) to each device.
To be able to provide power supply for high ability consumption 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 vitality.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Drawbacks AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra power cable or power.
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 disturbance, no sign 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 turn, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system based on PoE is a lot easier to manage, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I came across that WiFi IP video cameras are widely used for non-professional indoors security, and PoE IP cams are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how would you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many buyers often don't really know which type of cellular IP camera suites and would meet their needs. As a result, they get sucked into buying cordless 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 precision of data would you like to catch? (HD images with or without audio) and most importantly, what's your budget?
Second, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Certainly, this feature will depend on the environment where you would like to use the camera.
A wide skillet and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the kind of zooming capacity, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your neighborhood electronic store.
Always request for a test installation as this will permit you to look for the picture quality of the camera.
Furthermore, it will give you an opportunity to learn how to create the gear in an effective manner to ensure that you get the best image and audio tracks quality.
