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. Whenever you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and research which functions you want to attain.
WiFi or PoE, which is best? As a older technician that has 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 which allows network devices transfer data through cellular signal (2.4GHz UHF band, 5GHz SHF group).
Obviously, once the IP camera helps Wireless, the camera can connect your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is actually the advantage of WiFi.
But there are two disadvantages on WiFi, that happen to be; every electronic devices require power, which means your IP camera still requires wire for connection.
So far, I haven't found any IP camcorders are able to operate with battery power.
#3. WHAT LENGTHS Will 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 discussing WiFi coverage, we have a lot of things to consider including electricity rate of WiFi device, environment (interior or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters interior.
When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much significantly.
To extend the WiFi coverage or distance, you can set up WiFi gain access to point. This access point (or hotspot) has a variety around 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means 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 over one Ethernet wire (Cat5/6) is the main 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 permit IP cams support plug-and-play assembly, which greatly reduced the installation procedures, and get rid of the necessity of electric power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum vitality rate is to 15.4 W of DC ability (minimum 44V DC and 350mA) to each device.
To be able to provide power supply for high ability usage devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called 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
- Professional devices
#5. Drawbacks AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra vitality cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable, there is absolutely no signal disturbance, no transmission jamming.
For properly working of PoE devices, 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 change, which increased just a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install a unitary 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 WiFi router.
For more than one IP camera, PoE is preferred. PoE is much reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to deal with, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I found that Wireless IP surveillance cameras are widely used for non-professional indoor security, and PoE IP camcorders are installed for outdoor surveillance system. But if you select WiFi IP Camera please read article below.
So how would you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many purchasers often don't really know which kind of wireless IP camera suites and would satisfy their needs. As a result, 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 glowing); what detail of data would you like to get? (HD images with or without audio) and most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Naturally, this feature will be based upon the surroundings where you would like to use the camera.
A broad skillet and tilt range is never an awful thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the type of zooming ability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never neglect to find one with optical move.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your neighborhood electronic store.
Always obtain a test installation 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 an effective manner to make certain you get the best image and audio tracks quality.
