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 Wireless and PoE at same time. If you hook up the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and check out which functions you want to achieve.
WiFi or PoE, which is a good? As a senior technician that has four years in video tutorial monitoring industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cellular transmission (2.4GHz UHF band, 5GHz SHF band).
Obviously, after the IP camera facilitates WiFi, the camera can hook up your router without using hardwired connection. WiFi can permit IP camera become lightweight, this is the advantage of Wi-fi.
But there are two downsides on WiFi, that are; every gadgets require power supply, which means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cameras have the ability to operate with batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including vitality rate of WiFi device, environment (indoors or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters indoors.
When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much much.
To increase the WiFi coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a variety of about 20 meters (66 feet) 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 sole Ethernet cable television (Kitten5/6) is the main feature of PoE technology.
So long as your IP camera helps PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play assembly, which greatly reduced the set up procedures, and get rid of the necessity of ability cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electric power rate is to 15.4 W of DC vitality (bare minimum 44V DC and 350mA) to each device.
In order to provide power 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 power.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Downsides AND PROS OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Electric power 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 when compared to a traditional network move, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is recommended. PoE is a lot reliable than WiFi in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to manage, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I found that WiFi IP surveillance cameras are trusted for non-professional in house security, and PoE IP cams are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.
So how do you really determine which cordless IP camera suits your preferences?
Firstly, establish what you need. Many potential buyers often don't really know which type of cellular IP camera suites and would gratify their needs. As a result, they get sucked into buying cellular IP camcorders that are beyond what they need.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what accuracy of data would you like to record? (HD images with or without audio) & most importantly, what's your budget?
Second, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Naturally, this feature will depend on the surroundings where you would like to use the camera.
A wide pan and tilt range is never a bad thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Make sure that you check the kind of zooming capabilities, 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 focus.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your local electronic digital store.
Always obtain a test setup as this will allow you to determine the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to create the equipment in a proper manner to ensure that you receive the best image and audio quality.
