WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. When you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the installation environment and check out which functions you want to attain.
Wi-fi or PoE, which is a good? As a older technician who may have four years in training video monitoring industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through wireless signal (2.4GHz UHF strap, 5GHz SHF group).
Obviously, after the IP camera supports Wi-fi, the camera can hook up your router without using hardwired connection. Wireless can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two downsides on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable television for connection.
So far, I haven't found any IP surveillance cameras are able to operate with battery packs.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have many things to consider including power rate of Wi-fi device, environment (interior or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters in house.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much significantly.
To extend the Wi-fi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range of about 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over one Ethernet cable television (Cat5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP camcorders support plug-and-play assembly, which greatly reduced the set up procedures, and eliminate the necessity of electricity 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 electric power (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high power consumption 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 power.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Drawbacks AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable connection, there is no signal interference, 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 much expensive than a traditional network move, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use Wireless IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I came across that Wireless IP camcorders are trusted for non-professional indoor home security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.
So how do you determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many clients often don't really know which kind of cellular IP camera suites and would fulfill their needs. As a result, they get sucked into buying cordless IP cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or shiny); what perfection of data would you like to capture? (HD images with or without music) and most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Needless to say, this feature will rely upon the environment where you intend to use the camera.
A wide skillet and tilt range is never a poor thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the kind of zooming functionality, 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 equipment before purchase.
That is vital, especially when you are buying from your local electric store.
Always obtain a test set up as this will enable you to look for the picture quality of the camera.
In addition, it will offer you an chance to learn how to set up the equipment in a proper manner to make certain you get the best image and audio quality.
