WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. While you connect 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 installation environment and check out which functions you want to attain.
WiFi or PoE, which is the best? As a mature technician who has four years in training video surveillance industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cellular signal (2.4GHz UHF group, 5GHz SHF group).
Obviously, once the IP camera supports Wi-fi, the camera can connect your router without needing hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of WiFi.
But there are two drawbacks on WiFi, which can be; every electronic devices require power supply, that means your IP camera still requires cable for connection.
Up to now, I haven't found any IP cams are able to operate with batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting 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 have many things to consider including vitality rate of Wireless device, environment (indoors or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage extends to up to 10 meters interior.
When Wireless devices will work outdoor without hurdle, the transmission distance will be much very good.
To increase the Wi-fi coverage or distance, you can install WiFi gain access to point. Such an access point (or hotspot) has a variety around 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for 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 supply over sole Ethernet cable connection (Cat5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play unit installation, which greatly reduced the set up procedures, and eliminate the necessity of electricity cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum vitality rate is to 15.4 W of DC electricity (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high power intake devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called 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 Access Point
- Network Routers
- Industrial devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra ability cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable tv, there is no signal interference, no signal jamming.
For properly working of PoE devices, Electricity sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network turn, which increased just 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 choose to use WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. 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 power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I found that Wi-fi IP camcorders are widely used for non-professional inside 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 will you determine which wireless IP camera suits your needs?
Firstly, establish the thing 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 camcorders that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or excellent); what accuracy of data do you want to catch? (HD images with or without sound) & most importantly, what is your budget?
Second, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Obviously, this feature will rely upon the surroundings where you would like to use the camera.
A wide skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Make sure that you check the type of zooming potential, 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 gear before purchase.
This is vital, especially when you are buying from your local electronic store.
Always request for a test setup as this will allow you to look for the display quality of the camera.
Furthermore, it will offer you an opportunity to learn how to set up the gear in an effective manner to make sure that you have the best image and audio tracks quality.
