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 WiFi and PoE at same time. Once you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the installation environment and research which functions you want to attain.
WiFi or PoE, which is the better? As a mature technician who may have four years in video tutorial surveillance industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through wireless indication (2.4GHz UHF strap, 5GHz SHF band).
Obviously, after the IP camera helps 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 WiFi.
But there are two downsides on WiFi, that happen to 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 surveillance cameras are able to operate with battery packs.
#3. WHAT LENGTHS DOES 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 discussing WiFi coverage, we have a lot of things to consider including electricity rate of Wi-fi device, environment (indoors or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters indoor.
When WiFi devices are working outdoor without hurdle, the transmission distance will be much far.
To increase the Wireless coverage or distance, you can install WiFi gain access to point. This gain access to point (or hotspot) has a variety of about 20 meters (66 toes) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over single Ethernet cable (Cat5/6) is the key 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 permit IP camcorders support plug-and-play installation, which greatly reduced the set up procedures, and get rid of the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electric power rate is to 15.4 W of DC power (least 44V DC and 350mA) to each device.
To be able to provide power supply for high ability utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial 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 tv, no need extra vitality 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 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. Wi-fi VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized vitality solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of monitoring market, I came across that Wireless IP video cameras are trusted for non-professional in house home security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wireless IP Camera please read article below.
So how do you really determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many potential buyers 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 wireless IP surveillance cameras 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 bright); what accuracy of data would you like to catch? (HD images with or without audio) and most importantly, what is your budget?
Second, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Needless to say, this feature will depend on the environment where you would like 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 vital.
Ensure that you check the kind of zooming capacity, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never fail to find one with optical move.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your local electronic digital store.
Always request for a test installation as this will enable you to look for the picture quality of the camera.
Furthermore, it will offer you an opportunity to learn how to create the equipment in an effective manner to make certain you receive the best image and music quality.
