WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both WiFi and PoE at same time. When you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the set up environment and research which functions you want to achieve.
Wi-fi or PoE, which is the best? As a mature technician who has four years in training video 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 transfer data through cordless indication (2.4GHz UHF strap, 5GHz SHF band).
Obviously, after the IP camera facilitates Wireless, the camera can hook up your router without using hardwired connection. Wi-fi can allow IP camera become portable, this is the advantage of Wi-fi.
But there are two downsides on WiFi, that are; every gadgets require power, which means your IP camera still requires cable for connection.
So far, I haven't found any IP surveillance cameras have the ability to operate with battery power.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have a lot of things to consider including electric power rate of WiFi device, environment (inside or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters in house.
When Wi-fi devices will work outdoor without hurdle, the transmitting distance will be much considerably.
To extend the Wireless coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 foot) indoors and a larger 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 solitary Ethernet wire (Pet cat5/6) is the primary feature of PoE technology.
So long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum 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 electric power usage devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Disadvantages AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable, there is absolutely no signal interference, no transmission 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 than a traditional network swap, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I found that Wireless IP camcorders are widely used for non-professional in house home security, and PoE IP camcorders are installed for outdoor monitoring system. But if you select WiFi IP Camera please read article below.
So how do you really determine which wireless 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 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 consider: what conditions will the camera be located in? (Hallway, outdoor, low light or dazzling); what perfection of data would you like to get? (HD images with or without audio tracks) & most importantly, what's your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Naturally, this feature will be based upon the environment where you intend to use the camera.
A broad skillet and tilt range is never an undesirable thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Ensure that you check the type of zooming ability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, especially when you are buying from your neighborhood electric store.
Always obtain a test installation as this will enable you to determine the display quality of the camera.
In addition, it will offer you an chance to learn how to create the equipment in an effective manner to make certain you receive the best image and audio quality.
