WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi 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 Wi-fi 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 accomplish.
Wireless or PoE, which is the better? As a mature technician that has four years in video recording surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through wireless sign (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera facilitates Wireless, the camera can hook up your router without needing hardwired connection. WiFi can enable IP camera become lightweight, this is the advantage of Wireless.
But there are two downsides on WiFi, which are; every gadgets require power, that means your IP camera still requires cable tv for connection.
So far, I haven't found any IP camcorders have the ability to operate with batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting 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 many things to consider including ability rate of WiFi device, environment (inside or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters in house.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much far.
To extend 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 foot) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over sole Ethernet wire (Feline5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cams support plug-and-play unit installation, which greatly reduced the unit 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 can provide maximum vitality rate is to 15.4 W of DC power (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high electric power use 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 vitality.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Negatives AND Positives OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra electric power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable television, there is no signal disturbance, no signal jamming.
For properly working of PoE devices, Ability 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 when compared to a traditional network change, which increased just 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 Wi-fi IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I came across that Wi-fi IP cams are trusted for non-professional indoor security, and PoE IP surveillance cameras are installed for outdoor security system. But if you choose Wi-fi 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 cordless IP camera suites and would satisfy their needs. Because of this, they get sucked into buying wireless IP surveillance cameras 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 dazzling); what accuracy of data do you want to record? (HD images with or without audio tracks) & most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Naturally, this feature will rely upon the surroundings where you would like to use the camera.
A wide pan and tilt range is never an awful thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Ensure that you check the kind of zooming ability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never fail to find one with optical move.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your local electronic digital store.
Always request for a test setup as this will allow you to determine the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to create the gear in a proper manner to make sure that you have the best image and audio quality.
